F/R/L-Filter/Regulator Auto Drain Assembly

This is a Semi-Automatically drain for your regulator. The regulator will trap moisture in the bowl. When you disconnect the air source (compressor), the float will rise to the top of the water level in the bowl. When you connect the air source, the float will push the water out the bottom of the bowl, draining it automatically. This is a good way to keep your engraving system or your ParaBlaster moisture free without having to manually drain the water trap.
