HOFER’s product range incorporates robust diaphragm and reciprocating compressors with hydraulic drive as well as long-life valves and pipeline elements. They are used worldwide where gases or gas mixtures are handled and compressed safely under high pressure.

HOFER diaphragm compressors compress gases and gas mixtures technically attrition-free without applying lubricants.
As they work leak-free outwardly, they are especially suitable for highly superfine applications and for use with explosive, toxic and expensive gases. HOFER diaphragm compressors compress, for example, hydrogen, helium, argon, ethylene, fluorine, hydrogen sulfide, chlorine, monosilane or nitrogen trifluoride. Typically, HOFER diaphragm compressors are used, for example, for filling storage containers, feeding into continuous processes or as gas loop compressors.
HOFER compressors are marked by their construction details, which make the machines particularly safe, reliable and service-friendly.
