The advantages of AERZEN Blower series GR at a glance:
- The 1 or 2 stage process blowers GR can be used for almost all technical gases and gas mixtures, which may also be aggressive.
- Versatile blower stage (single and two-stage) for plant engineering for vertical and oil-free conveyance.
- Direct drive, with gear box or belt drive. Optionally available with liquid injection for gas cooling or purification, as well as with special modifications and materials.
Process gas blowers from AERZEN function reliably in all industries, in all markets, and in all countries on earth.

Blower Power For Special Requirements
The 1- or 2-stage process blowers GR can be used variably for almost all technical gases and mixed gases. In all industrial sectors. Ideal also for gases with negative intake temperatures down to -40 °C. The process gas blower type GR can also be used to convey aggressive gases Maximum pressure increase of 1.5 bar, maximum pressure 6 bar g
Design
The conveying chamber is completely separated from the oil sumps by a space open to atmosphere.
- Maximum pressure increase of 1.5 bar
- Maximum pressure 6 bar (g)
Shaft Seals:
Conveying chamber sealed by
- a) pressure relieved soft packings with purge gas connections,
- b) pressure relieved carbon ring - labyrinth seals with purge gas connections,
- c) double-acting mechanical seals, oil-purged,
- d) double-acting mechanical seals, water-purged.
Drive shaft by radial seal ring.
Direction og flow:
Vertically downwards.
Drive:
Direct via flexible coupling or via flexibly coupled spur gear. Overhung via narrow V-belt (up to 250 kW driving power).
Special materials: Depending on the particular operating conditions, models are also available in nodular graphite cast iron or CrNi cast steel.
