HF431/434/437

Product catalog summary

Technical Characteristics: The HF 431, HF 434, and HF 437 series are tank-mounted suction filters directly connected to the circuit's suction line. They feature an aluminum head, zinc-plated steel end cap and inner tube, and a stainless steel wire mesh filter media. A by-pass valve is available, set at 2.9 psi (0.2 bar).

Materials: The filters are constructed with an aluminum head, zinc-plated steel end cap and inner tube, and stainless steel wire mesh for the filter media.

Fluid Compatibility: These filters conform to ISO 2943 and are compatible with various fluids, including mineral oils (HH, HL, HM, HR, HV, HG), water emulsions (HFAE, HFAS), water glycol (HFC), and synthetic fluids (HS, HFDR, HFDU, HFDS).

Pressure and Filtration: The element collapse pressure rating is 14.50 psi (1 bar) as per ISO 2941. Filtration degrees are available in 60 µm, 125 µm, and 250 µm using stainless steel wire mesh.

Operating Temperature: The filters operate within a temperature range of -85 to 195 °F (-30 to 90 °C).

Dimensions and Flow Rates: Detailed dimensions and nominal flow rates are provided for each filter type (HF 431, HF 434, HF 437) with various connection sizes and filtration degrees. For example, the HF 431-10.077 model has a nominal flow rate of 13.2 US gpm (50 l/min) with a 60 µm filtration degree.

Ordering Information: To order a complete filter, specify the filter type, thread connection, suction connection, degree of filtration, and any optional features such as a by-pass valve.
