High Pressure Hydraulic Filter FMP 320 - 1-1/4" BSPP, 320 Bar

In-line pressure filtration that mounts straight after the pump and protects the expensive bits - valves, servo/proportional spools and motors - from pump-generated debris. Big-bore filtration for loaders, drill rigs, cranes and industrial systems - 1.75L element volume, reverse-flow check valve capability. Phosphatized cast iron head, steel bowl, 6 bar bypass, fatigue-tested to 1,000,000 pressure cycles.

Two ways to buy:

• Complete Filter - housing with the element already inside. Plumb in and go.
• Replacement Element - the microfibre insert only, for service time. All elements are ABSOLUTE rated (99.9% capture at the stated micron).

The picture changes as you pick - it always shows exactly what arrives in the box. All prices include GST.

Sizes & Part Numbers - every combination

How to Choose

• Micron: 10µm absolute suits most systems; 3-6µm for servo/proportional valves; 25µm for coarse protection duty.
• Check your working pressure is under the housing rating and your line size matches the ports - an undersized pressure filter is a pressure drop you pay for in heat.

Technicians Advice

Mount vertically, bowl down, and mind the flow arrow on the head. The differential indicator port ships with a T2-H blanking plug - swap it for a DEA/DLA/DVM indicator (below) and you will know exactly when the element is done; on a pressure filter a blocked element bypasses at 6 bar and everything downstream runs on dirty oil. Crack the bowl slowly at service - it holds pressure. Always fit a new element seal kit ring where supplied.
