Membrane Air Dryers

Membrane Air Dryers

& Gas Sample Dryers

Membrane Air Dryers and Membrane Gas Sample Dryers are essential components in a wide variety of compressed air applications. The special membrane fibers of the membrane air dryers provide a safe, effective, and efficient way to separate water from other molecules in compressed air systems and release it as dry air. Membrane gas sample dryers remove water molecules from a gas sample without affecting the concentrations of other components to be analyzed.

Whether you're working with environmental chambers and pneumatic automation systems or you have a waveguide drying or analytical instrumentation application, membrane dryers are often the best solution.

Standard Features:
  • Eco-friendly use with no refrigerants or desiccants
  • Air dryer models with outflows from 0.60 to 25 SCFM
  • Gas sample dryer models with outflows from 2 to 10 lpm
  • No power, moving parts or maintenance requirements
  • Patented membrane fiber technology
  • Safe for use in hazardous locations
Barrel Type Membrane Air Dryers:
These air dryers come in five distinctive models featuring ¼-inch to 1-inch port sizes. The larger membrane bundles used make barrel membrane dryers excellent choices for higher flow requirements.
Cassette Type Membrane Air Dryers:
If you need to install a membrane dryer into a tight space, this model is an effective solution. We carry six distinctive sized models ranging from 0.5 to 7 SCFM outflows to fit your specific installation and operation specifications.
Flexible Type Membrane Air Dryers:
This membrane air dryer can be utilized in confined spaces between critical components and actually bends to accommodate a tight fit. The model features a ¼-inch port size, 1.25 SCFM in, 1.0 SCFM out and choices of external valve or orifice purge control.
Gas Sample Dryers:
Gas Sample Air Dryer
These are an important component for conditioning gas samples before sensitive gas analyzers and in process monitoring applications. Models range from 2 to 10 LPM, feature maximum operating pressures of 72 PSIG, and a +5°F to 212°F operating temperature range depending on the model.
