This is especially important in humid areas, when you mount your regulator to your air compressor you should tightly wind the air hose connecting the regulator & tank outlet for two laps around the air tank/receiver. By doing this you will find the air gets cooler as it get to the regulator and therefore the regulator will draw a lot more moisture out of the usable air. By tightly winding the hose long way’s around the tank you will maintain portability of the air compressor whilst ensuring your tools are receiving the driest and cleanest air possible.
