MCA Series
CO2 Adsorbers

For Dry, CO2-Free Air up to 20.5 lpm

Altec AIR Carbon Dioxide Adsorber-Dryers (MCA Series) are designed to remove CO2 and moisture from compressed air. This dryer uses dual towers with 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.

The dual tower adsorber/dryer design performs two essential functions in one process eliminating the need for an additional unit, reducing costs. The regenerative design provide continuous clean dry, CO2-Free air.

Standard Features:
  • Reduces CO2 to less than 1ppm
