It works super well; he loves it because he can work much more efficiently with the compressor. 10/10! ### ⭐⭐⭐⭐⭐ Nice Design, quality parts, Perfect Addition To Shop *by R***C on 14 October 2022* 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.
