Heatless Air Dryers F-Dry


Take a look at our impressive collection of air dryers!

These beauties can supercharge your air compressor, making it work like a finely tuned machine, soaring with maximum efficiency.


F-DRY Series Heatless Regenerative Adsorption Air Dryers. For flows from 1200-6500 m3/h. Pressure Dew Points -40°C (-25°C / -70°C). Operating Pressure 4-16 bar. Operating Temperature Range 1.5 to 50°C.

F-DRY adsorption dryers are designed for continuous separation of water vapour from the compressed air thus reducing the pressure dew point. F-DRY series dryer consists of two columns, filled with desiccant beds, controller with LCD display, valves, manometers, support construction and suitable filter housings with the required filter element. Adsorption takes place under pressure in the first column while the second column regenerates with a portion of already dried compressed air at ambient pressure. When the first column is saturated to a certain level column switch-over is carried out and the process of adsorption continues in the second column without any drop of pressure at the outlet of the dryer. Regeneration of saturated desiccant is possible because a small portion of already dry compressed air is decompressed and when expanded it becomes extremely dry. This portion of extremely dry decompressed air also called “purge air” is then fed through the saturated column in the reverse flow direction in order to remove the adsorbed water molecules from the desiccant and release them back to the ambient.

Our vast selection of air dryers can enhance the efficacy of your air compressor by enabling it to operate with greater efficiency.
