HMD Series - Membrane Compressed Air Dryers
Membrane compressed air dryer
Air flow rates 2.6m³/h to 112,8m³/h
Our HMD series is a great alternative to refrigerated and adsorption air dryers. Membrane dryers can be selected independently from the desired pressure dew point and need no maintenance. In order to protect the delicate membrane surface, particle and oil-fine filtration are required.
- No electrical supply needed
- Low weight, simple installation
- Pressure dew point selective from +10°C down to -40°C
- No moving/rotating parts
- No oxygen loss
- No liquid condensates, as humidity leaves the unit in vapour condition

Membrane dryers can be selected independently from the desired pressure dew point and need no maintenance. In order to protect the delicate membrane surface, particle and oil-fine filtration are required. The appropriate filter combinations are available in our Hankison filter program.
Typical Applications:
- Control & Instrument Air for outside installations
- Ventilation in electr. control cabinets
- Laboratory applications where small flows are needed
- Ex-proof applications
- Supply of air for purged bearings (Turn tables)
- Point-of-use installations
Criteria for choosing HMD membrane dryers:
- Small flows in combination with high-quality pressure dew points
- No electrical supply is available
- Ex-proof application in combination with low capital investment
- Required high reliability (no rotating parts)
