In-line hydraulic return filters with 325 l/min flow

In-line hydraulic return filters with a flow rate up to 325 l/min are designed for installation on the return line of the hydraulic system. They clean the oil returning to the tank and help protect the pump, control valve, and other system components from contamination. In this category, filters AMF 601 CV 1BB606 are available in AHC and Sofima variants.

Parameters of 325 l/min return filters

• maximum flow: 325 l/min with oil viscosity of 30 cSt,
• filtration accuracy: 25 µm,
• internal thread on both sides: 1 1/2",
• maximum working pressure: 12 bar,
• burst pressure: 25 bar,
• bypass valve opening pressure: 1.7 bar,
• installation site: return line of the hydraulic system,
• can be mounted directly to the tank.

In-line filter with bypass valve

AMF 601 CV 1BB606 filters are equipped with a bypass valve. In case of heavy contamination or element blockage, it allows the oil flow to bypass and reduces the risk of damage to the filter housing. The valve opens at 1.7 bar pressure.

Where are 325 l/min hydraulic filters used?

Return filters with a capacity of 325 l/min are used in larger power hydraulic systems in agricultural, construction, and industrial machinery. They are installed on the return line, where they filter the oil before it returns to the tank.

A properly selected return filter limits the amount of contaminants circulating in the system and helps protect expensive hydraulic components, specifically pumps, control valves, valves, and hydraulic cylinders.

How to choose a return filter for the system flow?

The filter should have an adequate flow margin relative to the actual system capacity. With higher oil viscosity or low temperatures, flow through the filter element may decrease; therefore, a filter should not be chosen exactly at the system's capacity limit.

Before purchasing, you should also check the connection diameter, filtration accuracy, maximum working pressure, and bypass valve parameters. For filters in this category, connections have a 1 1/2" internal thread, filtration is 25 µm, and the maximum working pressure is 12 bar.

AMF 601 CV 1BB606 AHC and Sofima

Two variants of the AMF 601 CV 1BB606 filter are available in this category: AHC and Sofima. Both solutions are designed for oil filtration on the return line and operation in systems requiring flow up to 325 l/min.
