Hankison HMD Membrane Air Dryers

Membrane gas separation technology, used for years to generate nitrogen, is now widely used for compressed air drying. Operation is simple and reliable. Compressed air, saturated with water vapor, flows through a bundle of tube-shaped membranes (think of tiny drinking straws). Water vapor (and a fraction of the compressed air used to sweep the water vapor out of the dryer) passes through the membrane walls. Dry air then exits the tube bundle for use downstream. As long as the dried air isn’t exposed to temperatures below the dew point temperature produced by the dryer, no troublesome liquid water will form in your air system.

The membrane dyers may be sized to produce dew point temperatures from -40°F (-40°C) or below to +50°F (+10°C)

The beauty of Hankison membrane drying is its simplicity:

  • Lightweight - HMD Series dryers can be installed in air lines with-out additional support
  • Operates in any orientation making it easy to in corporate into existing equipment
  • Operates in a wide variety of environments - high and low temperatures, corrosive and explosive atmospheres, in doors or out
  • Housings are made of ABS polymer and aluminum; stainless steel housings are optional
  • Water is removed as a vapor - no liquid condensate to dispose of

Choice of Prefilter package:

  • For normal applications - a Hankison HF Series Grade 5 high efficiency oil removal filter
  • For highly contaminated systems or applications where the highest level of air purity is required -a Hankison HF Series Grade 7 airline filter and a Grade 3 ultrahigh efficiency oil removal filter

Air Filters include: auto drains and differential pressure indicators to signal the need for filter element replacement. Maximum working pressure: 250 psig (17.6kgf/cm2); maximum inlet temperature: 150°F (66°C)

HMM Series Continuous Flow Membrane Dryers
Modular Membrane Dryers

Hankison HMM Membrane Air Dryers

HMM Series Continuous Flow Membrane Dryers-Steady Performance 24/7

HMM Series modular membrane compressed air dryers provide clean, dry compressed air wherever you need it; no electricity required. Designed for continuous flow applications, HMM Series dryers pass a constant side-stream of dry sweep air to exhaust the extracted water vapor into the ambient surroundings.

HF Series Air Filtration
Proper operation requires the removal of contaminants like liquid water, compressor lubricant, dust, rust, and pipe scale before entering the dryer. Clean, filtered, compressed air will reward you with many years of satisfactory performance from your HMM Series dryer.

Reduce Power Costs
SweepSaver™ Series’ digital purge control (DPC) accepts your demand signal to open and close an integrated normally open, two-way valve to control the sweep air. A “zero demand” signal keeps the bore of the membrane fibers pressurized while DPC eliminates the waste of sweep air to save you energy. Initiate the process’ air demand signal to start the flow of sweep air.

Energy Efficient, Space Saving Designs

  • Inside-to-outside permeation dries compressed air to -40°F
  • Helically wound bundles for low pressure drop, high flow capacity
  • Modular connections reduce leak points and simplify installation
  • Space-saving vertical design for quick, clean, easy installation
  • Modular connections reduce leak points and mate up to HF Series filtration, add Grade 1 Filtration for oil-free air to ISO 8573-1 class 1.2.1
  • Energy saving Filter Monitor manages pressure drop (option)
  • Robust aluminum housings, internal and external epoxy powder coat offers durable protection
  • Energy saving Digital Purge Control synchronizes to air demand (SweepSaver™ Series only)
