GU-H self-sealing pressure filter – 0.35/0.4 MPa.

1. Product Description

Aite GU-H Series Self-Sealing Pressure Line Filter is equipped with a differential pressure transmitter. When the filter element 

is polluted and blocked until the pressure difference between the inlet and outlet is 0.35 MPa, a switch signal will be sent. At 

this time, the filter element should be cleaned or replaced to ensure the normal operation of the system.

Aite GU-H Series Self-Sealing Pressure Line Filter also features a bypass check valve. When the filter element is polluted and

 blocked to a pressure difference of 0.4 MPa, or the pressure difference between the inlet and outlet of the filter is too large 

due to other reasons, the bypass valve can be automatically opened to ensure the normal operation of the system.

Aite GU-H Series Self-Sealing 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 GU-H Series Self-Sealing 

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