Multiquip 8101070033 Fan DCA-70SSJU - OEM Replacement Part for Ultra Silent Generators

The cooling fan maintains optimal operating temperature for the generator's alternator and engine compartment in ultra-silent generator applications. This component is engineered specifically for the DCA-70USI series, which features a revolving field, self-ventilated, open protected type synchronous generator producing up to 70 kVA prime output at 1800 rpm. Proper cooling is critical in these enclosed, sound-attenuated units where heat dissipation is more challenging than in open-frame designs.

The fan works in conjunction with the ISUZU 4-cylinder turbocharged diesel engine to maintain safe coolant temperatures (system capacity 3.80 gallons) and prevent thermal shutdown during continuous operation. In the DCA-70USI configuration, this fan ensures adequate ventilation for both the generator windings and the compact engine compartment, which is essential when running at rated loads of 56 kW (3-phase) or 40 kW (single phase). Fan failure typically presents as elevated operating temperatures, reduced power output, or thermal overload trips.

Compatible with the following Multiquip generator models:

• DCA70USI
