Suction line filters with 40 l/min flow rate

Suction line filters in this category are designed for installation on the suction side of the hydraulic system. Their task is to protect the pump and other system components from contaminants found in the oil drawn from the tank. This category includes AMF 151 MN 1AB406 filters in AHC and Sofima variants.

Suction filters AMF 151 MN 1AB406

The available filters operate on the suction line and can also be mounted directly to the tank. Their design allows for protecting the hydraulic pump and control valve from larger contaminants before the oil reaches further into the system.

• filter type: AMF 151 MN 1AB406,
• mounting location: suction line,
• maximum flow according to product data sheets: 30 l/min at 30 cSt oil,
• internal thread on both sides: 3/4",
• filtration: 125 µm,
• maximum working pressure: 12 bar,
• burst pressure: 25 bar,
• bypass valve opening pressure: 0.3 bar.

The bypass valve protects the filter against overload

AMF 151 MN filters are equipped with a bypass valve. In case of contamination or blockage of the filter element, the valve allows the oil flow to bypass and reduces the risk of filter damage. For the available models, the bypass valve opens at a pressure of 0.3 bar.

Where are suction line filters used?

Suction filters are used in hydraulic systems of agricultural, construction, and industrial machinery. Installation before the pump helps limit the entry of contaminants into components requiring clean oil and supports the correct operation of the entire installation.

The filter can be used in systems with hydraulic pumps, control valves, and hydraulic cylinders, especially where protection of the suction side against solid particles is required.

How to choose a suction filter for a hydraulic system?

When choosing, consider the actual oil flow, its viscosity, operating temperature, and connection diameter. The suction filter should not cause excessive flow resistance, so it is worth maintaining a capacity reserve relative to the system requirements.

The manufacturer recommends using a filter with a higher flow rate than the minimum required, as thick oil or low temperature can reduce actual flow efficiency by even about 40%.

AHC or Sofima?

Two variants of the AMF 151 MN 1AB406 filter are available in this category: AHC and Sofima. Both are intended for mounting on the suction line, and the Sofima variant is a product of the Italian manufacturer Sofima.
