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 head is made of aluminium alloy, the bowl is cold-formed steel, and seals are made of NBR Nitrile, with FKM Fluoroelastomer available on request. The indicator housing is brass.
Pressure Specifications (ISO 10771-1:2002): Maximum working pressure is 0.7 MPa (7 bar), test pressure is 1.5 MPa (15 bar), and bursting pressure is 2.5 MPa (25 bar). The collapse differential for the filter element is 300 kPa (3 bar) as per ISO 2941.
Components: Multi-function filters are available with various filter housing sizes and configurations, including FMA11, FMA21, FMA22, FMA31, and FMA32, with different port sizes ranging from 3/8” to 1 1/2”.
Installation and Application: The filters can be used in suction, low pressure, or return lines. They are designed for flexibility and long life, with a large filter area for high dirt holding capacity.
Clogging Indicators: Visual or electrical indicators are available to monitor the filter element condition. The port for the indicator is a standard feature.
Recommended Flow Rates: For suction lines, fluid speed should be between 0.1 and 1 m/s, and for return or low pressure lines, between 1.5 and 4 m/s.
Ordering and Options: Various options are available for filter media, port types, seals, and accessories. The ordering chart provides detailed configurations for different filter models.
Spare Parts: Spare seal kits and filter elements are available, with part numbers provided for different models.
Note: All data are based on tests with mineral oil of 30 cSt viscosity and 0.9 kg/dm3 specific gravity. For fluids with different characteristics, refer to the catalogue's initial section.

FLUID SPEED When selecting the filter size, we suggest to consider also the max recommended fluid speed: - in suction lines normally 0,1< v < 1 m/s - in return or low pressure lines normally 1,5< v < 4 m/s RECOMMENDED FLOW RATES l/min at ∆ p Type 0,5 bar return or low pressure line 0,5 bar (return or low pressure line) N.B. All the data have been obtained with mineral oil having a kinematic viscosity 30 cSt and specific gravity 0,9 kg/dm3; for fluids with different features, please consider the factors described in the first part of this catalogue. All the data are obtained from test done at...
