1、EASY TO USE: The pressure regulating valve can be adjusted according to your needs to effectively remove the moisture in the air. Filter fine particles, keep the air clean, easy to install 2、CORROSION RESISTANT SHELL: The filter has aluminum alloy shell, pressure and corrosion resistant, durable, with long service life 3、USE METHOD: Pull up the large knob of pressure regulator, rotate to get the specified pressure you set, and can maintain this pressure for a long time. Increase pressure CW and decrease pressure CCW 4、EFFICIENT AND PRACTICAL: The oil cup atomizes the oil and sends the atomized oil to the components of the pneumatic tools to make them work better 5、LONG SERVICE LIFE: The compressor air filter pressure regulator provides the recommended air pressure required for proper operation and extended service life of pneumatic tools
