Product catalog summary

Compatibility: The filters are fully compatible with fluids HH, HL, HM, HV, and HTG as per ISO 6743/4. For other fluids, contact the Sales Department.

Working Temperature: The operational temperature range is from -25°C to +110°C.

Materials: The filter components are made of various materials: the head is an aluminum alloy, the bowl is steel, the bypass valve is polyamide, seals are NBR Nitrile, and the indicator housing is brass.

Pressure Specifications (ISO 10771-1:2002): The maximum working pressure is 2 MPa (20 bar), with a test pressure of 4 MPa (40 bar) and a bursting pressure of 6 MPa (60 bar). The collapse differential for the filter element is 300 kPa (3 bar).

Bypass Valve: The bypass valve is set at 170 kPa (1.7 bar) with a tolerance of ±10%.

Filter Housing: Various models are available (FPH31, FPH40, FPH50, FPH52) with different port sizes and dimensions.

Filter Element: The filter elements are available in different media types (F+, C+, M+) and sizes, providing a large filter area for high dirt holding capacity.

Clogging Indicators: Options include visual and visual-electrical differential indicators to monitor element conditions and indicate when replacement is necessary.

Pressure Drop Curves: The assembly pressure drop is calculated by adding the pressure drop values of the filter housing and the clean filter element, which should be less than 50 kPa (0.5 bar). Curves are provided for different flow rates and port sizes.

Mounting Flexibility: A second outlet allows for optional mounting configurations, making the PH series versatile for various applications.

Construction and Durability: The filters are designed for strong construction, ensuring resistance to fatigue at working pressures up to 2000 kPa (20 bar). The end caps with captive O-rings ensure no leaks.

Ordering and Options: Detailed charts are provided for ordering, including options for seals, bypass valves, and accessories.

PRESSURE FILTERS FLUID SPEED when selecting the filter size, we suggest to consider also the max recommended fluid speed (in pressure lines normally 5 < v < 10 m/s). PRESSURE DROP CURVES (Ap) The "Assembly Pressure Drop (Ap)" is obtained by adding the pressure drop values of the Filter Housing and of the Clean Filter Element corresponding to the considered Flow Rate and it must be lower than 50 kPa (0,5 bar). FILTER HOUSING PRESSURE DROP (mainly depending on the port size) N.B. All the curves have been obtained with mineral oil having a kinematic viscosity 30 cSt and specific gravity 0,9 kg/dm3;...
