The Echo DGK7F is a 7 kVA compact portable diesel generator — the smallest unit in Echo's diesel lineup. Built in Japan by Yamabiko Corporation (formerly Shindaiwa) with over 50 years of generator heritage and documented runtimes exceeding 30,000 hours. Powered by a Kubota Z482 two-cylinder diesel engine, the DGK7F delivers 5 kW prime power in a sound-attenuated enclosure measuring just 62 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 DGK7F 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. For contractors running a mix of 120V lighting and small three-phase equipment, the DGK7F replaces what would otherwise require two separate generators or a generator plus transformer setup, reducing both equipment cost and site footprint.
As authorized service providers in Northern California, we maintain Echo DGK Series generators across the Bay Area and Central Valley. The Kubota Z482 engine in the DGK7F is a proven industrial powerplant with excellent parts availability through Kubota's dealer network. Service intervals are straightforward — 250-hour oil changes and 500-hour fuel and air filter replacements. The compact size of the DGK7F makes it easy to transport for field service calls. Echo backs the DGK Series with a 3-year warranty, the longest in the portable generator class, reflecting Yamabiko's confidence in the Shindaiwa engineering heritage behind every unit.

Frequently Asked Questions
What is SimulPhase technology on the DGK7F?
SimulPhase is Echo's patented technology that allows a single generator to output both single-phase and three-phase power simultaneously without requiring an external step-down transformer. No other portable generator manufacturer offers this capability. On the DGK7F, SimulPhase enables 120/240V single-phase output, making it versatile for mixed-load jobsites where both lighting and small motor loads are present.
What is the runtime and fuel capacity of the DGK7F?
The DGK7F carries a 9.5-gallon integral fuel tank and consumes approximately 0.68 gallons per hour at full load (5 kW prime). This yields roughly 14 hours of continuous operation at full load before refueling. At typical 75% loading, runtime extends further. The compact Kubota Z482 engine is exceptionally fuel-efficient for its output class.
How does the Echo DGK7F compare to MQ Power or Airman at the same kW?
The DGK7F occupies a niche that most competitors do not address with a liquid-cooled diesel unit at only 7 kVA. MQ Power's smallest diesel models start around 10-15 kVA, and Airman's lineup begins at similar sizes. The DGK7F's advantages include its compact 42.7 x 25 x 34.9 inch footprint at only 744 lbs dry, 62 dBA sound level, and the SimulPhase dual-output capability that no competitor matches. The 3-year warranty — longest in the portable class — adds further value.
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. The brand was transitioned to Echo for North American distribution, but the engineering team, factory, and quality standards remain unchanged.
