The Doosan generator lineup represents one of the most trusted names in portable power generation for construction, events, emergency backup, and rental fleet applications. Originally manufactured by Doosan Portable Power (a division of Doosan Infracore), these rental-grade diesel generators span 30kW to 500kW and are built to withstand the demands of jobsite deployment, harsh weather, and continuous prime power operation. If you have searched for a Doosan portable generator, you have likely encountered the G-Series models — the G40, G70, G190, G240, G290, G325, G450, and G570 — each engineered with WhisperWatt sound-attenuated enclosures, multi-voltage selector switches, and EPA-compliant diesel engines from Mitsubishi, Cummins, and Yanmar.

Power Generation Enterprises (PGE) stocks 15+ Doosan generators at our Santa Clarita, California facility, with models ranging from 30KW compact portables to 500KW prime power units. Whether you are expanding a rental fleet, sourcing emergency backup for a hospital, or powering a large-scale construction project, this guide covers every Doosan model, the Bobcat rebrand, tier ratings, pricing, and why PGE is the right source for your next Doosan portable generator.

From Doosan Portable Power to Bobcat: The Rebrand Story

Understanding the relationship between Doosan and Bobcat generators is essential for anyone shopping the used portable generator market. Here is the timeline:

Doosan Infracore manufactured portable generators under the Doosan Portable Power brand for decades. These units — marketed under the WhisperWatt name — became the gold standard in rental-grade portable power. Rental companies including United Rentals, Sunbelt Rentals, and BlueLine Rental deployed thousands of Doosan G-Series generators across North America.

In 2021, Hyundai Heavy Industries Group acquired Doosan Infracore. As part of the corporate restructuring, Doosan Portable Power was folded into the Bobcat Company brand (Bobcat itself is a subsidiary of Doosan Bobcat, now operating under Hyundai). By 2022-2023, new portable generators previously sold as Doosan G-Series began shipping as Bobcat branded units.

The critical point for buyers: Doosan and Bobcat portable generators are mechanically identical. A Bobcat G570 rolling off the Statesville, North Carolina production line in 2024 uses the same Cummins X15 engine, the same alternator, the same control panel, and the same sound-attenuated enclosure as a Doosan G570 built in 2020. The only difference is the badge on the door. Parts, service procedures, and specifications are interchangeable.

This means the used market is filled with thousands of excellent Doosan-branded generators that are functionally identical to current-production Bobcat units — often at significantly lower prices. When you see a Doosan G325 for sale, you are looking at the same machine that would cost substantially more with a Bobcat badge and zero hours.

Complete Doosan Generator Model Lineup

Doosan manufactured eight primary G-Series portable generator models. Each model number roughly corresponds to the kVA rating (G40 = 40 kVA, G570 = 570 kVA), while the kW rating is typically 80% of the kVA figure. Here is the complete lineup with specifications sourced from factory documentation.

Doosan G40 — 30KW Portable Generator

The Doosan G40 is the smallest unit in the G-Series lineup and one of the most popular rental generators in North America. At 30kW (40 kVA), it handles single-building backup, small event power, and residential construction sites.

Prime Power: 28 kW / Standby: 30 kW (36 kW peak)
Engine: Mitsubishi 4IRS2N or Yanmar 4TNV98T (depending on production year)
Emission Tier: EPA Tier 4 Final

Dimensions: 130.5 in L x 73 in W x 78.5 in H
Voltage: 3-position multi-voltage selector switch
Enclosure: WhisperWatt sound-attenuated enclosure

The G40 is the go-to unit for rental fleets that need a compact, quiet generator that fits on a standard trailer. Its Tier 4 Final compliance means it can operate in CARB-regulated areas including California.

Doosan G70 — 56-58KW Portable Generator

The Doosan G70 bridges the gap between compact portables and mid-range worksite generators. Available in both Tier 3 and Tier 4i configurations, the G70 powers medium commercial buildings, multi-trade construction sites, and outdoor events with sound stages.

Prime Power: 56-58 kW (depending on tier rating)
Engine: Yanmar or Isuzu diesel (varies by production year and tier)
Emission Tier: Tier 3 or Tier 4i (production year dependent)
Sound Level: 65 dB(A) at 23 ft
Fuel Tank: 130 US gallons
Weight: Approximately 5,200 lbs
Voltage: Multi-voltage selector (120/208V, 240/480V three-phase)
Enclosure: WhisperWatt sound-attenuated enclosure

The G70 is popular with event companies and emergency response organizations because it delivers enough power for a medium-sized operation while remaining towable behind a standard pickup truck.

Doosan G190 — 150KW Portable Generator

The Doosan G190 is a workhorse in the mid-range portable generator segment. At 150kW, it handles multi-story commercial construction, large outdoor events, and temporary facility power for hospitals and data centers during planned outages.

Prime Power: 150 kW (190 kVA)
Engine: Cummins QSB7 or John Deere diesel
Emission Tier: Tier 4i / CARB compliant
Sound Level: 67 dB(A) at 23 ft
Fuel Tank: 280 US gallons

The G190 with CARB compliance is particularly valuable in California, where emissions regulations restrict which generators can be operated. PGE stocks Tier 4i/CARB G190 units specifically for Southern California customers.

Doosan G240 — 200KW Portable Generator

The Doosan G240 steps into the heavy-duty portable category. Powered by the Cummins QSB7-G9, this unit delivers 200kW in a still-towable package and is one of the most versatile generators in the Doosan lineup.

Prime Power: 188 kW / Standby: 200 kW (240 kVA)
Engine: Cummins QSB7-G9, turbocharged, 4-cycle, inline 6-cylinder, 6.7L displacement

Enclosure: WhisperWatt sound-attenuated enclosure

The G240 is a top seller for rental fleet operators because the 200kW output covers the majority of commercial power requirements while the 27-hour runtime at full load minimizes refueling trips.

Doosan G290 — 250KW Portable Generator

The Doosan G290 serves the upper-mid-range market where 200kW is not quite enough but a full 300kW+ unit is overkill. At 250kW prime, the G290 handles large commercial construction, hospital emergency backup, and multi-building event complexes.

Prime Power: 250 kW (290 kVA)
Engine: Cummins QSL9 diesel
Emission Tier: Tier 3
Sound Level: 70 dB(A) at 23 ft
Fuel Tank: 400 US gallons

PGE typically stocks multiple G325 units in both Tier 4i and Tier 4 Final/CARB configurations. The Tier 4 Final units command a premium but are required for California jobsite deployment.

Doosan G450 — 375KW Portable Generator

The Doosan G450 bridges the gap between mid-range portables and the flagship G570. Powered by the Cummins QSX15 engine, the G450 delivers 375kW of prime power for large industrial applications.

Prime Power: 375 kW (450 kVA)
Engine: Cummins QSX15
Emission Tier: Varies by production year (Tier 2, Tier 3, Tier 4 Final available)
Fuel Tank: 530+ US gallons
Enclosure: WhisperWatt sound-attenuated enclosure

Doosan G570 — 450-500KW Portable Generator (Flagship)

The Doosan G570 is the flagship of the G-Series portable generator lineup. At 450-500kW depending on configuration, the G570 is the largest truly portable generator Doosan manufactured — capable of powering entire construction sites, large data center modules during maintenance windows, and major outdoor festivals.

Prime Power: 456 kW (570 kVA) / Standby: 500 kW
Engine: Cummins X15, turbocharged, 4-cycle, inline 6-cylinder
Prime Engine Output: 680 hp (507 kWm) at 1800 RPM

Weight: Approximately 18,000 lbs (fully fueled)
Dimensions: 260 in L x 98.5 in W x 119.8 in H
Cooling: Liquid-cooled

PGE stocks both Tier 2 G570 units (typically lower-priced, suitable for non-CARB states) and Tier 4 Final/CARB G570 units for California-compliant applications. The Tier 4 Final G570 with CARB certification is one of the most in-demand large portable generators in the western United States.

Understanding Doosan Generator Tier Ratings

EPA emission tier ratings are one of the most important factors when purchasing a Doosan generator, particularly for buyers operating in California or other CARB-regulated states. Here is what each tier means for Doosan G-Series units:

Tier 2

The earliest emission standard found on used Doosan generators. Tier 2 G570 units are the most affordable large portables on the market and operate legally in most states — but not in California for most applications. Tier 2 units do not require DEF (Diesel Exhaust Fluid) or DPF (Diesel Particulate Filter) systems, which means lower operating costs and simpler maintenance.

Tier 3

A mid-generation standard found on many used Doosan G70, G290, and G325 units. Tier 3 generators use improved combustion technology to reduce NOx and particulate emissions. Like Tier 2, they do not require DEF or DPF aftertreatment. Tier 3 units are popular for non-CARB states where clean emissions are desired but Tier 4 costs are not justified.

Tier 4i (Tier 4 Interim)

The transitional standard between Tier 3 and Tier 4 Final. Doosan G190, G325, and other models are available in Tier 4i configurations. Some Tier 4i units include DPF systems but not SCR. Many Tier 4i Doosan generators carry CARB certification, making them legal for California operation.

Tier 4 Final

The current and most stringent EPA emission standard. Tier 4 Final Doosan generators include full aftertreatment systems — typically DPF plus SCR using DEF. The Doosan G40, G240, G325, and G570 are all available in Tier 4 Final configurations. These units meet CARB requirements for California operation and command the highest resale values in the used market.

CARB Compliance

The California Air Resources Board (CARB) enforces stricter emission standards than the federal EPA tiers. Not all Tier 4i or Tier 4 Final generators automatically carry CARB certification — manufacturers must separately certify each model. When buying a Doosan generator for California use, verify CARB compliance on the emission label. PGE clearly labels all CARB-compliant units in our inventory listings.

Key Features of Doosan G-Series Generators

Rental-Grade Construction

Every Doosan G-Series generator is built to rental-grade specifications. This means heavy-gauge steel enclosures, forklift pockets, lifting eyes, and tandem-axle trailers on larger models. Rental-grade construction is designed for repeated deployment, transport over rough terrain, and operation by multiple operators — exactly the durability profile that makes used Doosan generators excellent long-term investments.

WhisperWatt Sound-Attenuated Enclosures

The WhisperWatt designation is Doosan proprietary sound attenuation technology. WhisperWatt enclosures use multi-layer insulation, baffled air intake and exhaust paths, and vibration-isolated mounting to achieve sound levels as low as 64 dB(A) at 23 feet on the G40 — quieter than a normal conversation. This makes Doosan generators suitable for residential neighborhoods, hospitals, film sets, and outdoor events where noise ordinances apply.

Multi-Voltage Selector Switches

Most Doosan G-Series generators include a multi-position voltage selector switch that allows field-selectable voltage output — typically 120/208V three-phase, 120/240V single-phase, and 277/480V three-phase. This eliminates the need for external step-down transformers in many applications and makes a single generator model versatile enough for diverse jobsite requirements.

Integrated Distribution Panels

Larger Doosan models (G325, G450, G570) include integrated camlock distribution panels, twist-lock receptacles, and GFCI-protected convenience outlets. These built-in distribution features eliminate the need for separate power distribution boxes on construction sites, reducing setup time and equipment cost.

Extended Runtime Fuel Tanks

Doosan G-Series generators feature oversized base fuel tanks designed for extended unattended operation. The G570 carries 574 gallons — enough for 24+ hours at full load. This extended runtime is critical for emergency backup applications, remote construction sites, and overnight event power where refueling access is limited.

Applications for Doosan Portable Generators

Construction

Doosan generators are the backbone of construction site temporary power across North America. The G40 handles tool power and site lighting for small residential projects. The G190 and G240 power tower cranes, welders, and temporary HVAC for mid-size commercial construction. The G325 and G570 provide full-site power for high-rise construction, highway projects, and industrial facility builds. Rental-grade construction and WhisperWatt enclosures mean these generators survive years of rough jobsite conditions.

Events and Entertainment

Film production, outdoor concerts, sports events, and festivals rely on Doosan WhisperWatt generators because sound levels must remain below local noise ordinances. The G70 handles a single stage and lighting rig. The G190 powers a mid-size outdoor festival. The G570 supports major concert touring and multi-stage festival production. WhisperWatt sound attenuation is the key differentiator that makes Doosan the preferred brand for event power.

Emergency Backup and Disaster Response

Hospitals, municipal water systems, emergency operations centers, and FEMA response operations deploy Doosan portable generators when permanent standby systems fail or when temporary facilities require immediate power. The towable design means a G325 or G570 can be delivered and operational within hours of a power outage. Tier 4 Final/CARB models are required for California emergency deployments.

Rental Fleet Operations

National and regional rental companies are the largest buyers of Doosan generators. Rental fleet operators value the G-Series because of rental-grade durability, low maintenance requirements, WhisperWatt sound attenuation (which reduces noise complaints from end users), and high utilization rates. When rental companies cycle out Doosan generators at 5,000-10,000 hours, these units enter the used market in excellent condition with comprehensive maintenance records — which is exactly the inventory PGE specializes in sourcing.

Doosan Generator Pricing Guide 2026

Used Doosan portable generator pricing depends on model, hours, tier rating, CARB compliance, and condition. Here are the typical 2026 market ranges based on PGE transaction data and industry benchmarks:

If you have rented a portable generator on a construction site in the last 15 years, there is a good chance it was a Doosan. We stock G40, G70, G190, G240, G290, G325, G450, and G570 models from 30KW to 500KW at our Santa Clarita yard — Tier 2 through Tier 4 Final / CARB-compliant. Every unit gets oil analysis, load bank testing, and full documentation before we list it. Call (818) 484-8550 or browse our Doosan inventory online.

We sell more Doosan portables than just about anyone on the West Coast, and there is a reason for that. These generators were built for rental fleets — United Rentals, Sunbelt, BlueLine — which means they were designed to get beat up on jobsites and keep running. The WhisperWatt enclosures are legitimately quiet, the multi-voltage selector switches save you from hauling a transformer, and the Cummins and Mitsubishi engines under the hood are engines that every diesel shop in the country knows how to work on. That is why we keep coming back to Doosan when we source inventory.

Model	Power	Tier Rating	Enclosure	Typical Used Price
Doosan G40	30 kW	Tier 4 Final	WhisperWatt	$15,000 - $28,000
Doosan G70	56-58 kW	Tier 3 / Tier 4i	WhisperWatt	$18,000 - $35,000
Doosan G190	150 kW	Tier 4i / CARB	WhisperWatt	$28,000 - $55,000
Doosan G240	200 kW	Tier 4 Final	WhisperWatt	$32,000 - $65,000
Doosan G325	260 kW	Tier 4i / Tier 4 Final	WhisperWatt	$38,000 - $78,000
Doosan G570 (T2)	500 kW	Tier 2	WhisperWatt	$55,000 - $85,000
Doosan G570 (T4F)	450 kW	Tier 4 Final / CARB	WhisperWatt	$85,000 - $120,000

If you are buying a Tier 4 Final Doosan — the G240, G325, or G570 — you need to know about DEF. These units use SCR aftertreatment, which means a DEF tank that needs to stay full and fresh. We have seen guys park a Tier 4 Final generator for six months with old DEF in it, and then they are calling us about fouled injectors and a $5,000 aftertreatment repair bill. If the unit is going to sit, drain the DEF or replace it before you fire it up. It is the single biggest maintenance headache on these newer machines and it is 100% avoidable.

Tier 2 and Tier 3 Doosans do not use DEF at all — no SCR, no DPF, just a straight diesel engine. That is a big part of why they are still popular. Simpler to maintain, cheaper to run, and fewer things to go wrong. The trade-off is straightforward: if you are working in California, you need Tier 4 Final. Period. A Tier 2 G570 is about $40K cheaper but you cannot run it legally on a California jobsite. Outside of CARB states, Tier 2 and Tier 3 units are a smart buy — you get the same Doosan build quality without the aftertreatment complexity.

Doosan Generator Buying Tips

Verify the Tier Rating Matches Your Jobsite Requirements

Doosan made the same model — like the G570 — in Tier 2, Tier 3, Tier 4i, and Tier 4 Final versions. A Tier 2 G570 runs about $40,000 less than a Tier 4 Final version, but you cannot legally operate it on a California construction site. Before you buy any Doosan portable, confirm what Tier rating is required at your jobsite. If you are in California, you need Tier 4 Final or CARB-certified. Other states vary. Call us at (818) 484-8550 and we can walk you through the requirements.

Check the DEF System on Tier 4 Models

Tier 4 Final Doosan generators use a diesel exhaust fluid (DEF) aftertreatment system. These systems are reliable when maintained but expensive to fix when neglected. Check for DEF crystallization in the injector nozzle, verify the DEF tank heater works (critical for cold-weather operation), and confirm the SCR catalyst has not been damaged by bad DEF or overheating. A DEF system replacement on a G570 runs $6,000-$10,000.

The Fuel Tank Size Matters More Than You Think

Doosan portables come with different fuel tank configurations depending on the model year and options. A G570 with the standard 400-gallon belly tank gives you about 18 hours at 75% load. The extended 600-gallon option stretches that to 27 hours — the difference between refueling once per day and once every two days on a remote jobsite. Check the actual tank capacity before you buy, especially if fuel delivery logistics matter to your application.

Inspect the Distribution Panel — Not Just the Engine

Rental-grade Doosan generators come with multi-voltage distribution panels, typically offering 480V 3-phase, 240V single-phase, and sometimes 208V output via cam-lock connectors. These cam-locks take a beating in rental service — check every one for arc damage, loose contacts, and damaged boots. A distribution panel with burned cam-locks is a $2,000-$4,000 repair and a safety hazard. Every Doosan we sell at PGE gets a full panel inspection before delivery.

Understand the Doosan-to-Bobcat Transition

Doosan Portable Power was acquired by Hyundai Doosan Infracore and rebranded under Bobcat around 2022. The generator sets are mechanically identical — a Bobcat G570 is the same machine as a Doosan G570. But parts ordering and warranty support now route through Bobcat dealer networks. For used units, this rebrand has no practical impact on reliability or parts availability. The key components — Cummins or Doosan engines, Stamford or Leroy-Somer alternators — are all still widely supported regardless of the brand badge on the enclosure.

Frequently Asked Questions

What happened to Doosan generators?+

Doosan Portable Power was acquired as part of Hyundai Heavy Industries Group’s purchase of Doosan Infracore in 2021. The portable power division was subsequently folded into the Bobcat Company brand. New generators that were previously sold as Doosan G-Series models now ship under the Bobcat brand name. However, the generators themselves are mechanically identical — same engines, same alternators, same enclosures, same specifications. The used market still has thousands of Doosan-branded G-Series generators available, and they remain fully supported with parts and service. Power Generation Enterprises stocks 15+ Doosan generators at our Santa Clarita facility. Call (818) 484-8550 for current availability.

Are Doosan and Bobcat generators the same?+

Yes, Doosan and Bobcat portable generators are mechanically identical machines. When Doosan Portable Power was rebranded under Bobcat, the only change was the nameplate on the enclosure door. A Bobcat G570 uses the same Cummins X15 engine, the same Marathon or Leroy-Somer alternator, the same WhisperWatt enclosure, and the same control systems as a Doosan G570. Parts are fully interchangeable between Doosan and Bobcat branded units of the same model. For used generator buyers, this means Doosan-branded units offer identical performance to newer Bobcat units at lower prices. PGE carries both Doosan-branded units. Call (818) 484-8550 for details.

What size Doosan generators are available?+

Doosan manufactured eight primary G-Series portable generator models: the G40 at 30KW, G70 at 56-58KW, G190 at 150KW, G240 at 200KW, G290 at 250KW, G325 at 260KW, G450 at 375KW, and the flagship G570 at 450-500KW. All models feature WhisperWatt sound-attenuated enclosures and are built to rental-grade specifications. Power Generation Enterprises stocks models across this full range, with 15+ Doosan generators available at our Santa Clarita, California facility. The most popular models in our inventory are the G325 (260KW) and G570 (450-500KW). Call (818) 484-8550 to discuss which size fits your power requirements.

Are Doosan generators CARB compliant?+

Some Doosan generators are CARB compliant and some are not — it depends on the specific model and tier rating. Doosan Tier 4 Final models (G40 T4F, G240 T4F, G325 T4F, G570 T4F) generally carry CARB certification for California operation. Many Tier 4i models, including the G190 T4i and G325 T4i, also carry CARB certification. Tier 2 and Tier 3 Doosan generators are not CARB compliant and cannot legally operate in California for most applications. PGE clearly labels CARB compliance on all inventory listings and can advise on which units meet California requirements. Call (818) 484-8550 for CARB-compliant Doosan generator availability.

How much does a used Doosan generator cost?+

Used Doosan portable generator prices range from approximately $15,000 for a G40 (30KW) to $120,000 for a low-hour Tier 4 Final G570 (450-500KW). Typical mid-range pricing: G70 $18,000-$35,000, G190 $28,000-$55,000, G240 $32,000-$65,000, G325 $38,000-$78,000. Key factors affecting price include hours of operation, tier rating (Tier 4 Final commands 25-50% premium over Tier 2), CARB compliance, and overall condition. Doosan-branded units often sell for less than identical Bobcat-branded units, creating value for informed buyers. Contact Power Generation Enterprises at (818) 484-8550 for current pricing on specific models.
