Oil free screw compressor Cmax2

Cmax is the last generation of the oil free screw compressors intended for pneu-transport of loose materials. Cmax2 B can be mounted on both sides of car frame with direct drive from transmission with the help of cardan shaft. It can also be installed with an acoustic cover. The construction of B-Box arm allows flexibility during assembling into the vehicle.
