Abstract
A coalescing type gas filter includes a filtering element enclosed in an inner chamber which is housed in an outer chamber and a drain device to simultaneously drain accumulated liquid in both the inner chamber and the outer chamber. The drain device contains a pressure sensitive valve that regulates opening of the drain in response to a drop in pressure.
