AST8 filter for Downflow. Diethyl ether is adsorbed on activated carbon, but because of its low boiling point, the local head adsorption can reduce the capacity of the filter. Special impregnation allows a chemical reaction which increase the filter capacity. Air Science carbon filters are based on enhanced, activated carbon particle formulations from specially selected, naturally occurring raw material superior to wood or other organic sources. Our carbon is treated to attain the proper porosity and aggregate surface area and to react with several ranges of aerosolized chemicals moved through the filter by an air handling blower.
