Airman SDG25S-8E1 20kW Tier 4 Final Mobile Diesel Generator

The Airman SDG25S-8E1 is a robust, trailer-mounted mobile generator set designed for reliable power delivery in industrial, construction, and emergency applications. With a prime power output of 20kW (25kVA at 0.8 power factor), this unit features a sound-attenuated enclosure that minimizes noise levels to approximately 63 dB(A) at 23 feet, making it suitable for urban or noise-sensitive environments. Powered by a Yanmar 4TNV88C diesel engine compliant with EPA Tier 4 Final emissions standards, it ensures low environmental impact while providing efficient fuel consumption of about 1.6 gallons per hour at full load. Key features include a multi-voltage selector switch (supporting 240/480V and 120/240V configurations), a 70-amp main breaker for circuit protection, single-row camlock connections for quick setup, a 12V battery charger, and a 400W block heater for cold-weather starts. Mounted on a single-axle TRLR25 trailer, it offers excellent portability. Advantages over similar products include its compact design, low operating hours (only 25), and integrated fuel tank for extended runtime up to 24 hours. Drawbacks may include higher initial cost compared to non-Tier 4 units, but it excels in durability and compliance. This used unit appears in excellent condition with minimal wear, ideal for rental fleets or backup power needs.
