AFH holds an extensive range of diaphragm process gas compressors which can be supplied to API 618.

As they are outwardly leak-free, these compressors offer great suitability for superfine or ultra-pure applications and for use with explosive, toxic, corrosive, and expensive gases. They deliver total assurance of non-contaminating gas compression in the Oil and Gas, Petrochemical, refining, and speciality gas industries – including hydrogen compression.

These compressors are typically used for filling storage containers, feeding into continuous processes or as gas loop compressors.

The range covers applications in:

  • Petrochemical
  • Speciality Gases
  • Energy and Power Generation / Green Hydrogen
  • Silicon Manufacturing
  • R&D
  • Pilot Plants (typically hydrogen pilot plants)

These compressors are designed to handle:

  • Hydrogen (H₂)
  • Fluorine and nitrogen trifluoride (NF3)
  • Hydrogen sulfide (H₂S)
  • Ethylene (C2H4)
  • Other Hazardous and Corrosive gases such as chlorine

AFH supply and service bare shaft compressors, as well as fully engineered, skidded compression systems.

Catering for a wide range of duties, our compressors have many advantages:
Long working life due to hydraulically moved diaphragm
Pressures up to 3,000 bar
Oil and leak-free compression with advanced early leak detection systems
Designed to handle many highly specialist gasses with ultra high purity
