Features:

NFD Filters have an extremely large filtration area and flow capacity of 450 gpm.
NFD Filters can be configured for in-tank or inline applications
Vent and drain ports are standard
Aluminum alloy is water tolerant – anodization is not required for water based fluids (HWBF)
Screw-on lid provides easy access to filter element for replacement
Reusable contamination basket prevents re-entry of retained contaminants into the reservoir during element replacement
Filters can be fitted with clogging indicators to monitor the contamination level of the element
NFD duplex filters have a ball-type selector valve to provide continuous filtration and eliminate the need to shut-down the system during element changeout
