The HYDAC NFHD Series Inline Modular Duplex Industrial Filters provide continuous filtration for hydraulic and lubrication systems operating up to 500 PSI. Featuring a modular duplex design, changeover valve system, and convenient element access, these filters allow maintenance without system shutdown, helping minimize downtime and protect critical industrial equipment.

Product Description

The HYDAC NFHD Series Inline Modular Duplex Industrial Filters provide reliable, continuous filtration for industrial hydraulic and lubrication systems operating at pressures up to 500 PSI (34.5 bar). Designed for demanding applications where uninterrupted operation is essential, these duplex filters allow operators to switch between filter housings for element maintenance without shutting down the entire system.

Featuring heavy-duty construction and a modular duplex design, the NFHD Series incorporates two filtration assemblies connected through a changeover valve system. This configuration allows one filter assembly to remain in operation while the other is isolated for inspection or element replacement, helping minimize downtime, maintain fluid cleanliness, and protect critical hydraulic components.

The NFHD Series offers flexible filtration configurations to accommodate varying system requirements, including applications involving high-viscosity fluids and demanding operating conditions. Top-access filter elements simplify maintenance, while available differential pressure clogging indicators provide filter condition monitoring to help identify when servicing is necessary.

Ideal for industrial machinery, centralized lubrication systems, gearboxes, power generation, pulp and paper processing, shipbuilding, and heavy industrial equipment, HYDAC NFHD Series filters deliver dependable filtration performance, efficient maintenance, and improved operational reliability.
