HAUG Sirius Series: t/m 101 bar

HAUG Sirius Series: t/m 101 bar


The HAUG.Sirius series has been used for compressing air and gases since 1973 and is a very mature compressor concept that has been continually improved and developed over the decades. In the meantime, numerous variants for different applications have become available.


HAUG.Sirius compressors with magnetic coupling were developed by HAUG Sauer and ensure leak-free compression of gases. This hermetically sealed and completely wear-free drive was used by HAUG Sauer for the first time in a reciprocating compressor in 1989 and can be used for suction pressures up to 31 bar (abs).

Magnetic clutch
The HAUG compressor design achieves a permanent leakage rate of less than 0.001 mbar l/s.

Permanently hermetically sealed compressors at standstill and in operation
The hermetically sealed piston compressor is achieved by a drive with magnetic coupling
No wear of the sealing element
No sealing gas
No loss of energy
High suction pressure

Suction pressure up to 31 bar (abs)

Hermetically gas-tight, no loss of gas and no wear and tear
Low energy consumption, better efficiency, lower power consumption
Compact compressor
