Output is rated at 25 HP and below, with shaft power of 11 HP at 500 RPM and 23 HP at 1000 RPM. The output shaft is a 1-inch round with key. Intermittent torque falls in the 101-200 lb-ft range; check the application pages for the specific 120 lb-ft reference value for your installation. The integrated cartridge valve and single-hose connection reduce installation time, and the housing profile is designed to pass through a floor access panel without dropping the exhaust system.
