Product catalog summary

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

Working Temperature: The filters operate between -25°C and +110°C.

Materials: The head is made of cast iron, the bowl of steel, and the bypass valve and seals are made of NBR Nitrile, with FKM fluoroelastomer available on request. The indicator housing is brass.

Pressure Specifications: According to ISO 10771-1:2002, the maximum working pressure is 31.5 MPa (315 bar), test pressure is 47 MPa (470 bar), and bursting pressure is 95 MPa (950 bar). The collapse differential for the filter element is 2 MPa (20 bar) for the standard series and 21 MPa (210 bar) for series H+.

Bypass Valve: The setting is 600 kPa (6 bar) with a tolerance of ±10%.

Application Example: The document provides dimensions and specifications for filter housings and elements, including various port sizes and seal options.

Pressure Drop Curves: The assembly pressure drop is calculated by adding the pressure drop values of the filter housing and clean filter element, which should be less than 120 kPa (1.2 bar). The document includes detailed pressure drop curves for different media and configurations.

Clogging Indicators: Visual or visual-electrical differential indicators are available to monitor element conditions and indicate when replacement is necessary.

Maintenance: The design allows for easy maintenance with a hexagon end on the bowl for simple wrench use. A perfect O-ring seal is ensured regardless of the tightening torque.

Additional Information: For further technical details and options, refer to pages 182-183 of the catalog.
