QFH Series Air Filter Regulator is one of the auxiliary devices pneumatic instrumentation. The air pressure from the air compressor of 0.3 ~ 1.0MPa, after filtration and purification, can be adjusted from 0 to 0.16; 0 to 0.25; 0 to 0.4; within the range of 0 ~ 0.6MPa pressure either output value remains stable. Types of pneumatic air supply pressure as instrumentation and pneumatic automatic device to the accessory device unit and other pneumatic equipment.

     Regulator should be able to work properly under the following environmental conditions;

(1) the temperature is -25 ~ +55 ℃; 

(2) Relative humidity 5% to 95% 

(3) vibration frequency less than 25Hz, amplitude less than 0.5mm. 

(4) air regulator should not contain harmful impurities from corrosion using.
