Hydac_Filter_LPF

LPF Series
Inline Filters
1000 PSI • Up to 140 GPM

Features

  • LPF 35/55, 660 filters are manufactured with cast aluminum head and aluminum cold formed bowls.
  • Aluminum alloy is water tolerant - anodization is not required for water based fluids (HWBF) - except LPF 660.
  • LPF filters sizes 160, 240, and 280 are manufactured with cast aluminum heads, cold formed steel bowls and an aluminum (500 psi) or steel collar (725 psi).
  • LPF filters are a desirable substitute for spin-on filters when dynamic fluid conditions call for the superior durability and leakproof quality of a well-constructed cartridge filter.
  • Quick-response, bypass valves protect against high differential pressures caused by cold start-ups, flow surges and pressure spikes. Filters can also be supplied without bypasses.
  • The simple inline design minimizes pressure drop and provides the significant benefit of compactness. The use of lightweight materials, makes these filters ideal for mobile equipment applications.
  • On models LPF 160, 240 and 280, the bowl is affixed to the housing by means of an easily tightened and loosened aluminum or steel collar for fast element changeout.

Hydac_Filter_LF

LF Series
Inline Filters
1500 PSI • Up to 180 GPM

Features

  • Non-welded housing design reduces stress concentrations and prevents fatigue failure.
  • Aluminum alloy is water tolerant - anodization is not required for water based fluids (HWBF).
  • Inlet and outlet port options include NPT and SAE straight thread O-ring boss to allow easy installation without costly adapters.
  • O-ring seals are used to provide positive, reliable sealing. Choice of O-ring materials (Nitrile, Fluoroelastomer, EPDM) provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water base fluids.
  • Screw-in bowl mounted below the filter head requires minimal clearance to remove the element for replacement, and contaminated fluid cannot be washed downstream when element is serviced.
  • Differential Pressure Indicators. HYDAC indicators have no external dynamic seal. This results in a high system reliability due to magnetic actuation, thus eliminating a potential leak point.
  • A poppet-type bypass valve (optional) is separate from the main flow path (except LF 60 / 110) to provide positive sealing during normal operation and fast opening during cold starts and flow surges.

Hydac_FMND Series Filter

FMND Series
Inline Duplex Filters
3000 PSI • Up to 100 GPM

Features

  • The FMND filter consists of a ductile iron filter head with built-in change-over valve and three different lengths of screw-in filter bowls.
  • The FMND filter can be supplied with or without bypass valve, but includes vent and drain screws, and also a connection for a differential pressure clogging indicator.
  • Pressure equalization requirement is achieved by raising the change-over lever prior to switching it to the relevant filter side.
  • Fatigue pressure rating = maximum allowable working pressure rating.
