Combo Compressed Air Filter Regulator – This air pressure regulator combines the functions of air compressor filter and air compressor regulator, which can remove solid particles and condensate with compressed air and prepare air properly for many types of compressed air tools and equipment. High Quality Material – The air compressor regulator with gauge is made of high quality aluminum, which is stronger than ordinary models and more durable. Air Inlet: BSP1/2", Max Pressure: 1.0MPa, Measuring Range: 0-150psi. Simple to Use – Air Compressor Regulator Air Filter for Air Compressor With adjustable pressure control knob, you can pull up and turn the black knob at the top of the regulator to adjust the pressure you want. This will make your work more accurate. Diaphragm Design – The internal diaphragm design of the air compressor pressure regulator smooths and regulates the airflow, which also minimizes the negative effects of air pulsation and pressure imbalances created by piston compressors.
