## Description

Installation and Operating: 1. Please cleaning the port and fitting before installing, avoiding bringing dirty thing to the air path.2. Pay attention to direction of air flow and arrow pointing on body if match, minding port and tooth type if correct.3. Adjustment of pressure: Pull up the knob of adjustment of pressure up, clockwise rotation, pressure is rising. Anticlockwise rotation, pressure is down. Watch the air gauge and point range and adjust the required pressure, then press the button to the lock status.4. Water bowl excretion. When it is no air pressure, water bowl will automatic excrete. When it has air pressure, the drainage column will rise. Water bowl excreted, releasing the drainage column after drainage finished, then drainage column will automatic rebound, drainage ended. When the water level is beyond upper limit, please drainage. Otherwise that will cause poor dehumidification. Notice: Please be careful to use a wrench to tighten the fitting. It is normal if there are extra threads, you can feel free to use. The first installation may have an excretion reaction(Not leakage, for the first time the internal pressure is different from the outside, it is necessary to discharge the excess air first. In this case, please wait for a while.

Review: works as it should. only bad thing is you have to drain the pressure to drain the water would be nice if they have a valve or something to open and close.
Review: I actually installed two of these items in my shop. They really work well to eliminate water in the compressor air lines! I would definitely recommend to buyers looking for a quality Air Drying System. Product UPDATE I’m EXTREMELY DISAPPOINTED WITH MY PURCHASE OF TWO OF THESE DEVISES. My initial review was very positive, a huge MISTAKE. After less than 2 months of use, both units LEAK AIR AT THE FILTER BOWLS, the GAUGES BOTH LEAK AIR, the Very FRAGILE BOWL AIR RELEASE VALVES LEAK, and Neither Devise helps to remove water or condensation from my shop pneumatic system. These are just another piece of foreign JUNK. Cheaply made with cheap plastic parts, BUYER BEWARE, these devises are not worth your $ investment, and constant air component air leaks causing my compressor to run on very frequent cycles. JUNK WITH A HIGH PRICE. Don’t waste your hard earned $$ with this company’s JUNK PRODUCTS . Spend a little more, and get a better quality devise. A TOTAL WASTE OF MY MONEY!
