Parker FMD Compressed Air Membrane Dryers

FMD Series Compressed Air Membrane Dryers
FMD-Series membrane dryers are available in 10 models which can supply clean, dry compressed air with dewpoints as low as -40°F (@10 SCFM) and +35° F (@40 SCFM). These membrane dryers are engineered for easy installation, minimal maintenance, and long term reliability.

How It Works

The water vapor in the compressed air is removed by the principle of selective permeation through a membrane. The membrane module consists of bundles of hollow membrane fibers, each permeable to water vapor. As the compressed air passes through the center of these fibers, water vapor permeates through the walls of the fiber. A small portion of the dry air (purge flow) is redirected along the outside of each hollow fiber, carrying away the moisture-laden air which is then Exhausted to room atmosphere. The remainder of the dry air is piped to the application. In all cases a Grade 10 prefilter and a Grade 6 coalescer are installed upstream of the dryer module for 99.9985% removal of oil aerosols and mists.
