Professional-grade regulator with pressure gauge and integrated water-trap; allows the precise control and delivery of clean, dry air for airbrushing. Internal diaphragm design smoothes and regulates the airflow; minimizing the negative effects of air pulsations and pressure imbalances created by piston-style compressors. Water and other contaminates are filtered from the airflow by a small-micron brass element and captured in a removable catch-bowl at the bottom of the regulator. Bowl features a spring-loaded valve for easy draining of any accumulated water. Adjustable pressure control knob: pull up and turn the black knob at the top of the regulator to set desired pressure. Pushing down on the knob locks the current setting. Rated up to 150 psi (gauge displays up to 100 psi). Regulator body has a 1/4" BSP female inlet and outlet, and we provide two male-to-male reducers (1/8" BSP to 1/4" BSP), allowing you to convert the inlet, outlet, or both to 1/8" BSP males for easy connection to airbrush compressors and hoses. Mounting bracket is provided and inlets and outlets are permanently marked on the regulator body to make installation a breeze.
