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.
