The HL 425-100V compressor is an oil-lubricated compressor equipped with two universal quick couplings: one for maximum pressure and the other for reduced pressure. The compressor weighs 57 kilograms. It has a 3.0 HP/2.2 kW motor, two cylinders, and a speed of 2850 RPM. The switch-on pressure is set at 6 bar, the maximum pressure at 8 bar, and the effective delivery rate is 314 l/min. With the pressure reducer, identifiable by the black knob, you can quickly and easily set the desired working pressure, which can be read on the manometer to the left of the pressure switch. The quick coupling for maximum pressure is directly connected to the pressure vessel and is located before the pressure reducing valve. The pressure in the pressure vessel can be read on the manometer to the right of the pressure switch.
