Aerzen Vacuum-Blowers

Aerzen Positive Displacement Blowers {type Roots) have been manufactured since 18fi8 and today are highly developed standard production machines designed and adapted to find use in a wide variety of applications.roots vacuum pump

Fields of application

Conveying of air and neutral gases.

Vacuum from 10 mbar to approx. 300 mbar for mHV-blowers

available in 11 sizes for theoretical nominal suction volume flow from 250 to fi1.000 m3lh.

The max. admissible differential pressure depends on the thermal load.

(See performance diagrams/chart匯page 3)

Design

blousing with an additional third soci<et on the in-

let side for the pre-inlet cooling. Due to the O-ring

seals the housing flanges are vacuum-tight, air-

cooled. Splash oil lubrication.

Shaft sealings

Conveying chamber by combined oil stinger- piston ring labyrinth seals. Driving shaft by double radial seal rings with grease barrier.

Direction of flow (viewed onto driving shaft)

vertical to the hottnm

Drive

Direct coupling with motor or via spur gear, narrowv-bell drive restricted to the smaller pressure dif-fereniials. 

Mechanical load

directly coupled匯profile 10.1           up to 12.5 mHV

up to 900 mbar

profile 13.f7          up to 17.15 mHV

up to 800 mbar

profile 18.17 up to 20.21 mHV

up to 600 mbar

with belt drive

applicable to all sizes up to a load of 250 mbar

Special material

Designs of the housing parts in nodular graphite cast iron EN-GJS-400-18U-LT {GGG 40.3)
