Compressed air is a safe and reliable power source that is widely used throughout the industry. In proportion to its wide utilization, problems caused by coalesced liquid in compressed air are increasing rapidly. Therefore, WF (Water-Free) is employed to remove moisture in compressed air to enhance its reliability.
Operating Principle
Compressed air is inserted (flow) into ① Cover expanding rapidly through the ② DIFFUSER to become unstable by colliding with ③ MESH HOUSING separating it into water and moisture. Separated water collected at ④ MESH FILTER falls into the ⑥ AUTO DRAIN and reaches a certain height to drain off. Dried air comes through ⑤ BODY
