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.

Design

Housing with circular flanges and o-ring seals, lube- and purge oil supply by complete oil unit, oil chambers under gas pressure.

Shaft sealings

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.

Direction of flow

Vertical, from top to bottom.

Drive

Direct coupling with motor or via flexibly coupled spur gear.

Booster design

Max. pressure increases of 1.0 bar abs. to 2.0 bar abs.
Housing compression-proof for PN 25 with o-ring sealings
Splash lubrication
Driving shaft seal by 2 shaft seal rings with grease trap
Drive direct via flexible coupling or overhung via narrow v-belt
