HANKISON HMM1-3F Membrane Air Dryer

The HANKISON HMM1-3F is a membrane air dryer rated for a maximum flow of 1.4 cfm with 3/8 in NPT inlet and outlet connections. It delivers compressed air to ISO Class 2 through 6 with a pressure dew point of 40 Degrees F. The aluminum body handles up to 200 psi and 150 Degrees F operating temperature. Automatic drain removes condensate without manual intervention.

Who this suits and who should look elsewhere

This dryer suits workshops and mobile rigs needing point-of-use drying for low-flow pneumatic tools or instrumentation where a 3/8 in port fits existing plumbing. It is not for buyers who need higher flow rates, larger port sizes, or lower dew points than 40 Degrees F. Systems requiring ISO Class 1 air quality or flows above 1.4 cfm will require different equipment.

Bundled accessories and software impact

The unit is compatible with F02-B-PF/HF filter elements for upstream particulate and coalescing filtration. No electronic controls, sensors, or software are included. Installation relies on standard NPT threading and the automatic drain function reduces routine maintenance tasks.

Questions about this item

Do I need a compressor that can supply up to 1.4 cfm at 200 psi for this dryer to work?

Yes, the dryer is rated for a maximum flow of 1.4 cfm and a maximum operating pressure of 200 psi, so the compressor must meet or exceed those figures.

Can I keep my existing 3/8 in NPT fittings when installing this unit?

Both the air inlet and outlet use 3/8 in NPT connections, so your current 3/8 in NPT fittings will thread directly onto the dryer.

How can I confirm the dryer is delivering ISO Class 2–6 air after installation?

Measure the outlet dew point; the dryer is specified to achieve a 40 °F dew point, which corresponds to the stated ISO classes when operating within its 1.4 cfm and 200 psi limits.
