PneumaticPlus Dryspell Plus 250 Heatless Regenerative Desiccant Air Dryers includes pre and after filters - 250 cfm, 1-1/2" NPT
Drying Cycle
Moist air from the compressor is sent through the coalescing filter. Here water & oil coalesces, gets purged through the auto drain valve. The relatively clean air with water vapor passes through the aluminum drying tower filled with desiccant, gets completely dried (up to -40F PDP), and then passes through a built in after filter. The desiccant fines from the towers are completely removed and clean dry air is let out through the outlet port for use.
Regeneration Cycle
During the regeneration cycle, the sudden depressurization brings out water molecules trapped in the desiccant pores to the surface of the beads. A small portion of dry compressed air from the drying tower then passes over the desiccant through the regeneration orifice built in the Top Block. This results in complete regeneration of the desiccant.
