GEA Grasso M series

GEA Grasso M compressors are the first screw compressors with an integrated pressure-activated check valve ensuring low pressure drop.

 
The integration of the suction filter and coupling housing greatly simplify assembly of the package. The outstanding energy-efficiency of these compressors is based on the infinitely adjustable capacity combined with the extended variable Vi-range (internal volume ratio). The variable speed from 1,000 to 6,000 rpm ensures a wide operation range and maximum efficiency in full and part load.
