NFD Series
In-Tank / Inline Duplex Filters
360 PSI • Up to 450 GPM
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
