Nugent Compact Economy duplex filters and strainers are designed for positive removal of solid contaminants from pressure liquid systems. This compact one-piece cover/valve assembly can be Cast Iron or Cast Steel; has excellent flow characteristics up to 60 gpm.

The duplex provides continuous filtration and uninterrupted flow when either element is being replaced. The one piece cover contains a straight bore transfer valve with “O”ring seals. 180 movement of valve handle diverts flow from one shell to the other. The valve can be positioned to utilize both shells simultaneously, but this defeats the purpose of the duplex feature and is intended only for emergency service. An arrow cast into the handle indicates which filter is in use.
