The Echo DGK45F is a 45 kVA portable diesel generator with patented SimulPhase technology for simultaneous single-phase and three-phase output. Built in Japan by Yamabiko Corporation (formerly Shindaiwa), this unit is powered by an Isuzu 4LE2X four-cylinder diesel engine delivering 36 kW prime power. The DGK45F offers triple voltage output — 120/240V, 208V, and 480V — and produces just 63 dBA at 7 meters in its sound-attenuated enclosure. Backed by a 3-year warranty, the longest in the portable generator class. Tier 4 Final and CARB compliant with S.E.T. Smart Emissions Technology for active DPF regeneration under light loads.
The DGK45F features Echo's patented SimulPhase technology — a capability unique in the portable generator market. SimulPhase allows the unit to deliver single-phase and three-phase power simultaneously from a single generator, eliminating the need for external step-down transformers on mixed-load jobsites. No competing manufacturer offers this dual-output capability at any size. At 45 kVA with triple voltage options, the DGK45F is a workhorse for construction sites running 120V power tools and lighting alongside 208V HVAC equipment and 480V motor loads — all from one compact unit that fits on a standard trailer.
As authorized service providers in Northern California, we maintain Echo DGK Series generators across the Bay Area and Central Valley. The DGK45F occupies the mid-range sweet spot in Echo's lineup — powerful enough for serious construction work, yet compact enough at 83 x 37 x 61 inches and 2,634 lbs wet weight for easy trailer transport. The Isuzu 4LE2X engine shares its platform with the DGK36FS, so parts and service procedures are consistent across the mid-range fleet. The 79-gallon fuel tank provides genuine multi-day runtime capability at 28+ hours full load. S.E.T. Smart Emissions Technology handles DPF regeneration automatically, preventing the manual regeneration hassles that plague some competitors' Tier 4 systems. 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 DGK45F?
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 DGK45F delivers 120/240V single-phase, 208V three-phase, and 480V three-phase output simultaneously — making it exceptionally versatile for mixed-load construction sites where both lighting and motor loads are present.
What is the runtime and fuel capacity of the DGK45F?
The DGK45F 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 beyond 35 hours, enabling multi-day operation between fuel stops.
How does the Echo DGK45F compare to MQ Power or Airman at the same kW?
At 45 kVA, the DGK45F competes with the MQ Power DCA-45SSI and Airman SDG45S. The DGK45F's defining advantage is SimulPhase — simultaneous single and three-phase output that no competitor offers. At 63 dBA, it is quieter than most competitors in this class. The triple voltage output (120/240V, 208V, 480V) provides flexibility that typically requires separate generator configurations from other brands. The 3-year warranty is the longest in the portable segment, backed by Shindaiwa's documented 30,000+ hour field runtimes.
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.
