Review on 🐷 NANPU Piggyback Semi Auto Compressed Regulator by Sheppard Priest

Good air regulator and filter + water separator that drains water automatically. Sometimes oil or debris in the collection cup can clog the float and cause the auto drain to bind, but if this happens you can turn the bottom screw to drain it manually and you can disconnect the unit, remove the cup and clean it . to make it work again. If you're not using a lot of air you might be better off with a manual drain that drains automatically when the pressure is released, but if you need something that drains under pressure while still using air this is great for the price. The controller is good too. Would make a decent filter/regulator/drain for a vent station. If you're using it permanently plugged in, I would turn off the air before and after so you can depressurize the unit to clean it without bleeding all the other air lines. I have quick connects installed on it and use it with my portable compressor because I have a different filter pack for my stationary compressor, but it costs $100 more than this unit and doesn't have an auto drain so I'm very happy with the cost of this one device .
