Like sizing a generator, the right compressor will be dependent on the air requirement (scfm) of your tools. Mobile spray rigs use several pieces of air operated equipment, all of which put a demand on the air compressor. The drum pumps, spray guns, agitators (optional), and fresh air supply systems (optional) all require compressed air. Other tools in your trade may also require compressed air. For example scarifiers used in the foam industry can require up to 30 scfm of air.
Another consideration is space and weight. MaxForce offers two types of compressors: Electric driven piston compressors and a belt driven screw compressor mounted on the generator.
Electric compressors are cost effective and are available on vertical or horizontal mounted tanks. Vertical tanks are used in our 16 ft., 20 ft. and box truck models — the horizontal tanks are mounted above the cab-over of our gooseneck trailers.
Our screw compressor option is mounted on our 40 kW generator and runs directly off the diesel engine — so there is no electrical requirement. In most applications a tank is not required saving weight and space making the screw compressor a great value option for 20 ft. bumper pull trailers.
