TO S E R I E S : F E AT U R E S

Haug has been manufacturing oil-free compressors since 1953. The TO series
has been in use for compression of air and gases since 1973. Our know-how in
the field of special plant and systems engineering, combined with our sophisticated modular system, make it possible to construct complex systems meeting
maximum quality and engineering standards and tailored precisely to the customer's needs.

• Oil-free, non-lubricated
reciprocating compressor

TO series compressors with magnetic couplings (Series TOG) are a Haug development suitable for continuous compression of gases with no leakage (leakage
rate <0.001 mbar l/s). Haug first incorporated this hermetically tight and
absolutely wear-free drive system into a compressor in 1989; it is suitable for
suction pressures up to 10 bar.

• Magnetic coupling or shaft seal

Haug compressors with shaft seals (Series TOD) achieve gas tightnesses of
0.01 mbar l/s. This gastight variant is a rationally priced alternative for compression of gases. Maximum suction pressures for this system are restricted to
3 bar. Haug has been using this shaft-seal system for compressors for oil-free
compression of gases since 1978.
Repeated innovations and continuous refinement have made Haug TO series
gas compressors an absolute high-tech product that now provides the ideal
solution for safe, reliable and oil-free compression of gases in the 5.5 to 30 kW
power range.
