Quality Assurance: brand new and high quality. Light weight, small size, easy installation and maintenance. Can filter small particles, keep the air clean.Principle: The air filter regulator is the one that adjusts the main air pressure channel to a pressure value that the control device requires after decompression filtration.Use to control pressure element and delay, overflow regulator.Features: copper filter material, finer filter and longer service life. Polymer material capacity cup, high strength heat resistance is not easy to aging, good sealing, waterproof, no air leakage.Multiapplication: Air compressors, pneumatic tools, gas connection installation, effective air moisture filtration, suitable for construction machinery, teaching experiments, equipment, machinery manufacturing, etc.Installation: The piping should be installed in the direction indicated by the arrow on the valve body, which is the direction of gas flow.Specification: Material: Metal, PlasticJoint pipe bore: 1/4"Filter accuracy: 40mAdjustable pressure range: 0.58.5kg/cm2Max adjustable pressure: 8.5kgf/cm2Operating temperature range: 560Water filter cup capacity: 15ccPackage Included: 1 x 1/4" Air Filter
