QFHS 281 Series Stainless Steel SS316 Air Filter Regulator
The QFHS-281 Series Stainless Steel Air Filter Regulator is a heavy-duty, high-precision auxiliary component designed to regulate compressed air pressure while ensuring superior fluid purification. It effectively takes an inlet pressure of 0.3–1.6 MPa from an air compressor and regulates it down to a stable, custom-adjusted output pressure within the range of 0.05–0.8 MPa.
Engineered specifically for hazardous and highly corrosive environments, the QFHS-281 series boasts a robust, compact, and simple structure that guarantees rock-solid reliability where standard regulators fail. Featuring an automatic relief function, it immediately exhausts air into the atmosphere if the output pressure exceeds the pre-set limit, ensuring constant system stability and downstream equipment protection.
