The Mapro Positive Displacement Blower consist basically of a pair of
Tri-lobe rotors, mounted on parallel shafts, rotating in opposite
directions inside a properly shaped casing closed at the ends by side
plates. The two Tri-lobe rotors are synchronized by a pair of timing
gears. As the rotors rotate, air is drawn into the inlet side of the
casing, is moved from the inlet to the outlet side by the free
volumes, between rotors and stator and finally is forced out of the
outlet side against the connected system pressure. The blower does not
develop pressure within the casing but the discharge pressure depends
only upon the connected system resistance. Motor: 22 kW - 400 V - 50
