The 402-1080 Aluminium Inlet Filter provides effective water filtration before water enters a pressure-washer pump. Its stainless-steel filter screen captures dirt and other particles that could contribute to blocked valves, damaged seals or premature pump wear.

The compact, low-profile housing combines a durable aluminium body with a removable plastic cap, allowing access to the filter screen for routine inspection and cleaning. It handles water flows up to 22 litres per minute, temperatures up to 80°C and inlet pressures up to 12 Bar.

A ½″ BSP female inlet and ½″ BSP male outlet allow the filter to be installed directly into a suitable pressure-washer water supply. Two additional ¼″ BSP female ports provide connection points for compatible bypass or return arrangements.
