The DRIERITE Laboratory Air and Gas Drying unit is an all-purpose drier. This unit is suitable for most laboratory applications. It will dry air to a dew point of -100° F at atmospheric pressure or pressures up to 90 psig. A simple connection by rubber hose to the bottom inlet of the dryer provides an immediate flow of dry air or gas. This unit is also available with 1 /8 inch SS NPT fittings. Plastic coated mounting clips may be purchased separately. Continuous flows are possible with two units in the line and the necessary valves so that the exhausted column may be refilled while the alternate column remains in use.
