VCD Series
CO2 Adsorbers

For Dry, CO2-Free Air to 99 lpm

The VCD Series Carbon Dioxide Adsorbers are designed to remove CO2 from compressed air. The Adsorber does this by using media beds featuring 13X molecular sieve in a pressure swing adsorption process. Adsorbed moisture and CO2 are vented to atmosphere while dry CO2-Free air is provided at the outlet port.

Design Features includes direct acting solenoid valves for positive shifting and reliable flow control, fixed orifice designed for consistent, trouble free purge flow. Components are easily serviced and field replaceable, continuously self-regenerative operation. Standard voltage is 115 VAC, & 230 VAC is available as an option. Standard operating pressures from 50 to 150 psig.

Standard Features:
  • Outlet CO2 content to less than 1 PPM
  • Outlet H2O content to less than (-100°F dew point)
  • Compact and lightweight design requires less space
  • Solid state timer with built-in memory for energy savings come standard
  • NEMA 1 Electrical
  • Purge mufflers and power cord come standard
Optional Features:
  • Available Input Voltages
    • 115 VAC
    • 230 VAC
