Compressed air is a reliable power source that is widely used throughout many industries. One of the common issues with using compressed air is that condensation can happen from the severe temperature changes that may occur during the compression process. If the compressed air is mixed with any moisture, it may cause damage to the equipment that the compressed air is supplied to. The Water-Free Unit was designed to remove any moisture from the compressed air.

Operating Principle

Compressed-air is supplied into ① the INLET port on the Water Free, then the air passes through ② the DIFFUSER. Compressed-air that passes through the DIFFUSER is usually a combination of air and moisture. The incoming compressed air is pushed into ③ the LIQUID SEPARATOR. The moisture falls through the LIQUID SEPARATOR, and the air is able to exhaust out without any moisture.

② Diffuser
③ Liquid Separator
④ Filter
⑤ Water-Free Unit Body
⑥ Auto-Drain
