GEA GRASSO M SERIES

The GEA Grasso M series comes in eight sizes with a swept volume ranging from 231 to 870 m³/h / 136 to 512 cfm (at 2,940 rpm).

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.
