QU-H40 pressure line filter – 32 MPa, 0.35 MPa signal.

1. Product Introduction

Aite QU-H40 Pressure Line Filter is installed in the hydraulic system pressure pipe to filter mechanical impurities mixed

 in hydraulic oil and gum, asphaltene, and carbon slag produced by chemical changes in the hydraulic oil itself.

 Aite QU-H40 Pressure Line Filter prevents valve core sticking, throttle orifice gap and damping hole plugging, and 

hydraulic component wear failures.

Aite QU-H40 Pressure Line Filter has good filtering effect and high precision. The hydraulic oil filter element must be 

replaced when blocked. Aite QU-H40 Pressure Line Filter is provided with a differential pressure signaling device. 

When the filter element is polluted and blocked until the differential pressure of the inlet and outlet is 0.35 MPa,

 the switch signal will be sent.

Aite QU-H40 Pressure Line Filter is engineered as a fully interchangeable substitute for original models – maintaining 

identical dimensional parameters, interface specifications, and filtration performance to enable direct drop-in installation

 without any housing modifications.

As a professional manufacturer specializing in industrial filtration equipment, we deliver Aite QU-H40 Pressure Line Filter 

with stable performance, reliable construction, and competitive pricing for industrial facilities worldwide.
