•PRESSURE REGULATOR - With the adjustable pressure control knob, you can pull up and turn the black knob at the top of the regulator to set desired pressure. No matter the size of the inlet pressure and flow fluctuations, always maintain a stable outlet pressure.
•GAUGE&FILTER CUP - The pressure gauge is more accurate to the pressure induction and the metal shell is resistant corrosion. The dial scale has two units of measurement: psi and mpa. The Max pressure is 150 PSI. The filter cup is designed to be transparent for observing the volume of water and oil.
•EXTRA ACCESSORIES - The ball valve is made of forged brass for corrosion resistance, ductility at high temperatures and low magnetic permeability. It has a plastic-covered lever handle for on/off manual control. Some necessaries are also included in this kit: a double MNPT fitting and a thread seal tape.
•PIGGYBACK- Air pressure regulator combines the functions of both air filter and regulator. It is compact and much effective when space is constrained. The bracket is designed to provide a secure way to mount a filter regulator and easy removal.
