The SWG^™ Series consist of both flexible and non flexible shell and tube membrane dyers designed for use with sample or carrier gas. There are several models available that can accommodate flow rates up to 12 L/min. The flow pattern through the dryer is bidirectional, allowing for mounting flexibility as the inlet port can be at either end. This series of dryers does not have a built in purge so either an external purge gas source or rerouting dried gas from the outlet for use as purge gas is required. In order to protect the membrane dryer from solid and liquid contaminants, a prefilter (also available from A+ Corporation) should be installed on the inlet side of the dryer.
