Operating Instructions
Side channel vacuum pumps / Side channel compressors
Pump ranges
These operating instructions concern the following side channel vacuum pumps and compressors: SAH
The performance curves showing capacity against vacuum or pressure can be seen in data sheets D 556 / 1, D 556 / 2 and
D 556 / 3 or D 656 / 1, D 656 / 2 and D 656 / 3.
Description
All SAH models work according to the dynamic compression principle utilising a non contact rotating impellor. They have
a built-in motor. A high efficiency two stage impellor is fitted on to the motorshaft. Models up to SAH / 4.8 kW (picture
ᕡ)
use the motor fan for cooling. Models SAH / 5.5 kW and larger (picture ᕢ) have an additional cooling fan situated between
the motor and blower housing.
Air inlet and outlets have built-in silencers with the addition of a mesh disc on the suction silencer to protect the unit from
particles larger than 5 mm. Both the inlet and outlet have an inside connection thread corresponding to DIN ISO 228.
Versions of the SAH have on the suction side a solenoid valve and on the pressure side different connection flanges.
All the parts are made from a special aluminium alloy except for the motor rotor, stator and shaft.
Optional extras: As required, vacuum or pressure limiting valve, non-return valve, suction filter, motor starter, vacuum/
pressure change over valve.
Special versions: anti corrosive internal coating, gas tight version.
