Air blowers AERZEN GM ... dz with direct drive are high-performance units. Design with 1 or 2 stages and separate pressurized oil lubrication system provides oil-free pumping and compression of air, inert gases, gas mixtures. Extremely robust Roots design with improved performance.
Body with round flanges, O-rings, oil supply for lubrication and flushing, oil chambers under gas pressure.
The tightness of the discharge chamber is ensured by combined labyrinth seals with an oil deflector and a piston ring. Condensate collection chamber between the piston rings or shaft seal and the piston ring of the labyrinth seal.
The drive shaft is sealed by a double, oil-flushed, compressible mechanical seal.
