【High Quality Material】: The air filter regulator is made of high quality aluminum+PC+plastic, which is rust-proof, corrosion-resistant, strong and durable. 【Air Filtration】: The structure is compact and combines the functions of an air filter and a regulator. Filters moisture and fine particles for clean, dry air that prevents damage to air tools, spray guns and pneumatic equipment. 【Easy to use】: The pressure gauge is more accurate for pressure sensing, and the casing is corrosion-resistant. The dial scale has two units of measurement for easy control and reading. 【Pressure Regulator】: With the adjustable pressure control knob, you can pull up and turn the black knob on the top of the regulator to set the desired pressure. Always maintain a stable outlet pressure regardless of inlet pressure and flow fluctuations. 【Stable Performance】: The internal diaphragm design smoothes and regulates airflow, thereby minimizing the negative effects of air pulsations and pressure imbalances created by piston compressors., Manufacturer: DEWIN
