In-line filters with 170L/min flow

In-line return hydraulic filters with a flow rate of up to 170 l/min are designed for installation on the return line of a hydraulic system. Their task is to trap contaminants from the oil returning to the tank and protect sensitive installation components such as pumps, distributors and valves. This category includes AMF 301 CV 1BB606 filters in AHC and Sofima variants. :contentReference[oaicite:0]{index=0 }

Key parameters of 170 l/min return filters

• maximum flow: 170 l/min with oil viscosity of 30 cSt,
• filtration: 25 µm,
• internal thread on both sides: 1 1/4",
• maximum operating pressure: 12 bar,
• burst pressure: 25 bar,
• bypass valve opening pressure: 1.7 bar,
• installation location: return line of the hydraulic system,
• possibility of mounting directly to the tank.

These parameters apply to the AMF 301 CV 1BB606 filters available in this category. The Sofima version is an original filter from the Italian manufacturer Sofima, while the second variant occurs as AMF 301 CV 1BB606 AHC. :contentReference[oaicite:1]{index=1 }

In-line return filter with bypass valve

A significant element of the design is the bypass valve. In the event of contamination or blockage of the filter element, it allows the oil flow to bypass, reducing the risk of filter damage. For this series, the bypass valve opens at a pressure of 1.7 bar. :contentReference[oaicite:2]{index=2 }

Where are 170 l/min return filters used?

In-line filters with a flow of 170 l/min are used in agricultural, construction and industrial hydraulics. They are installed on the oil return to the tank to reduce the amount of contaminants circulating in the system and protect components that require a clean working medium. :contentReference[oaicite:3]{index=3 }

This type of filter can be used, among others, in systems with hydraulic pumps, distributors and hydraulic cylinders. Proper filtration helps reduce component wear and extend the maintenance-free operation time of the installation.

How to choose a hydraulic filter with a flow of 170 l/min?

When selecting a filter, one should not be guided solely by the nominal pump flow. The manufacturer recommends using a filter with an appropriate capacity reserve, as higher oil viscosity or low temperature can reduce the actual flow by up to approximately 40%. :contentReference[oaicite:4]{index=4 }

Before purchasing, also check the diameter and type of thread, filtration accuracy and allowable operating pressure. For filters in this category, connections have an internal thread 1 1/4", filtration is 25 µm, and the maximum operating pressure is 12 bar.

170 l/min return filters in the HYDRON offer

The category includes two variants of AMF 301 CV 1BB606 filters: AHC and Sofima. These solutions are designed to protect hydraulic systems on the return line, particularly in agricultural machines, construction equipment and industrial installations. :contentReference[oaicite:5]{index=5 }
