Finite's FMD Membrane Dryer Series is designed to remove water vapor and aersols at point-of-use for intermittent flows up to 40 SCFM with a +35°F dewpoint and 10 SCFM with a -40°F dewpoint.

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.

NOTE: 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.

Desiccant Types available: (Desiccant sold separately)
• Silica Gel -(FSGM100-1 = 5 lb can) 100 % indicating silica gel provides maximum moisture adsorption and dewpoints down to -40°F.
• Molecular Sieve -(FMS100-1 = 5 lb can) molecular sieves are crystaline, metallic aluminum silicates. The type 4A offers exceptional water vapor adsorption characteristics. Molecular sieves are more effective than silica gel at removing water vapor at elevated inlet temperatures. Dewpoints are attainable to -40°F.
