The direct-drive GM ... dz blowers from AERZEN are high-performance machines. One- or two-stage design, with separate pressurised oil lubrication for the oil-free transport and compression of air, neutral gases, and gas mixtures. Highly advanced and extremely robust Roots-type products. Available in a wide range of special materials and seals, such as stainless steel or as acetylene boosters according to TRAC norms.
Housing with circular flanges and o-ring seals, lube- and purge oil supply by complete oil unit, oil chambers under gas pressure.
Conveying chamber by combined oil slinger piston ring labyrinth seals with condensate chamber between the piston rings or shaft seal ring - piston ring labyrinth seal.
The drive shaft is sealdes via compressed-oil-purged double-acting mechanical seal.
Vertical, from top to bottom.
Direct coupling with motor or via flexibly coupled spur gear.
Max. pressure increases of 1.0 bar abs. to 2.0 bar abs.
Housing compression-proof for PN 25 with o-ring sealings
Driving shaft seal by 2 shaft seal rings with grease trap
Drive direct via flexible coupling or overhung via narrow v-belt
