MOISTURE SEPARATOR (FOR VACUUM)

This moisture separator removes liquids from the gas stream in a vacuum process.

This helps protect the blower from corrosion and the build up of mineral deposits.

HORIZONTAL SWING TYPE CHECK VALVE

This check valve prevents backwash of fluids from entering the blower and air back-streaming.

The check valve can be mounted to discharge or inlet either vertically or horizontally. The check

valve will open with 3” of water pressure or vacuum.

Maximum vacuum allowed: 22”Hg.
