The Echo DGK36FS is a 36 kW single-phase portable diesel generator built in Japan by Yamabiko Corporation (formerly Shindaiwa). Powered by an Isuzu 4LE2X four-cylinder diesel engine, the DGK36FS delivers 36 kW prime power through a dedicated 120/240V single-phase configuration. The 79-gallon integral fuel tank provides approximately 28 hours of continuous full-load operation. The sound-attenuated enclosure produces 65 dBA at 7 meters. Tier 4 Final and CARB compliant with S.E.T. Smart Emissions Technology for active DPF regeneration under light loads.
The DGK36FS is powered by the Isuzu 4LE2X — an upgraded variant of the 4LE2T used in Echo's 20-25 kVA models. The 2.179-liter inline four-cylinder diesel runs at 1800 RPM and delivers the additional power output needed for 36 kW prime rating. Isuzu's industrial diesel engines are widely deployed across construction equipment worldwide, providing excellent parts availability and a large service technician knowledge base. S.E.T. (Smart Emissions Technology) manages Tier 4 Final DPF regeneration automatically under light loads, preventing soot buildup without operator intervention — critical for rental fleet applications where operators may not understand regeneration procedures.
As authorized service providers in Northern California, we maintain Echo DGK Series generators across the Bay Area and Central Valley. The DGK36FS is particularly popular for residential construction and commercial tenant improvement projects where dedicated single-phase 120/240V power is needed at output levels that smaller units cannot reach. The 79-gallon fuel tank provides genuine multi-day runtime capability, reducing fuel delivery logistics for remote sites. The Isuzu 4LE2X engine shares many service procedures and consumables with the 4LE2T platform in the smaller DGK20FS and DGK25F, simplifying fleet maintenance. Echo's 3-year warranty — the longest in the portable class — reflects Yamabiko's confidence in the Shindaiwa engineering heritage behind every unit.

Frequently Asked Questions
What is SimulPhase technology on the DGK36FS?
SimulPhase is Echo's patented technology that enables simultaneous single-phase and three-phase output from a single generator without external step-down transformers. No other portable generator manufacturer offers this capability. The DGK36FS is configured as a dedicated single-phase unit (120/240V), optimized for high-output single-phase applications where 36 kW of clean, stable power is required.
What is the runtime and fuel capacity of the DGK36FS?
The DGK36FS carries a 79-gallon integral fuel tank and consumes approximately 2.8 gallons per hour at full load (36 kW prime). This provides roughly 28 hours of continuous operation at full load before refueling. At typical 75% loading, runtime extends well beyond 35 hours, enabling multi-day operation between fuel stops on most construction schedules.
How does the Echo DGK36FS compare to MQ Power or Airman at the same kW?
At 36 kW single-phase, the DGK36FS fills a niche that many competitors address only with three-phase units requiring derating for single-phase loads. The DGK36FS delivers a full 36 kW of dedicated single-phase output without derating. The 79-gallon fuel tank provides 28+ hours of runtime at full load — competitive with larger units. At 2,620 lbs wet weight, it remains trailer-portable. The 3-year warranty is the longest in the portable segment, and documented Shindaiwa 30,000+ hour runtimes demonstrate class-leading durability.
What is the Shindaiwa heritage behind Echo generators?
Echo generators are manufactured by Yamabiko Corporation in Japan, which acquired Shindaiwa — a company with over 50 years of industrial generator manufacturing experience. Shindaiwa-built generators have documented field runtimes exceeding 30,000 hours. The DGK Series carries forward this heritage with Japanese engineering and quality control. Echo backs every DGK unit with a 3-year warranty, the longest in the portable generator class.
