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.
Oil free screw compressor Cmax3
Unique characteristics of oil free compressor Cmax3:
- low weight,
- high performance,
- low temperature on outlet,
- optimal dimensions.
Oil free and contactless compressor Emax2
Unique characteristics of oil free and contactless compressor Emax2:
- a simple design,
- simple and cost effective installation,
- direct prop shaft drive,
- reversible rotation for drives,
- very short discharging time of silos when pneu-transport of loose materials,
- clean air, free of any contamination,
- undemanding maintenance and service,
- a robust construction of machine guaranteeing trouble-free operation,
- a low-speed drive is more advantageous in consideration of durability,
- low noise levels and low noise frequency,
- real compressor performance 260 to 490 m3/h and pulsating source of air enables excellent aerating qualities when pneu-transport of loose materials,
- working excess pressure 2 bar.
