Made of aluminum, the filter regulator is stronger, more durable, and more compact than ordinary filters, and it also serves as an air filter and regulator. This unit removes solid particles and condensate from compressed air to properly prepare air for many types of compressed air tools and equipment. With the adjustable pressure control knob, you can turn the black knob on the of the regulator to set the desired pressure, enabling precise control. The internal diaphragm design smooths and regulates airflow, minimizing the negative effects of air pulsation and pressure imbalance created by piston compressors. Suitable for a wide range of applications and equipment, including: Automotive workshops using impact wrenches, spray guns, and air ratchets that require clean, stable air. Woodworking shops using nailers, staplers, and sanders that benefit from regulated pressure. Painting or finishing tasks that need a consistent, pulsation air supply.
