Oil-free compressors designed for long service life
J. P. Sauer & Sohn Maschinenbau
The HAUG.Sirius HP 450 (photo) is a powerful high-pressure compressor that is entirely oil-free to ensure excellent gas purity. The hermetically gas-tight construction of the compressor achieves extremely low leak rates and enables four-stage compression of almost any gas, says the manufacturer. With a volumetric flowrate capacity up to 60 Nm³/h, the compressor operates at a suction pressure of 5 bars(g) and a final pressure of 450 bars(g). From the oil-lubricated side, this company offers the Tornado WP3325 B3-5 BasBooster-R compressor, which achieves a final pressure of 400 bars(g) and a suction pressure of up to 5 bars(g). With a leak rate of only 0.1 mbar/L/s, this range of models enables the compression of valuable gases, such as helium, with virtually no losses. Hall 8.0, Stand D24 — J. P.
