FS-Curtis CA13-H 13-HP Honda Engine Driven 30-Gallon Horizontal Two-Stage Air Compressor with 12VDC Starter with Alternator. The CA13-H engine drive compressor features the same industrial-quality pump as the 7.5HP stationary CA units in a package designed to be mounted on a service truck, so that your air compressor can go with you to where the work is. Like stationary CA machines, the CA-13H eliminates commonly used plastic parts and maintains low pump speeds to ensure that it will stand the test of time on a busy service truck. The CA13-H is a great choice to provide air for most of the pneumatic applications that a typical service truck encounters, including pneumatic impact wrenches, drills, nibblers, nailers, sanders, polishers, and grinders..
