RJB Posted February 27, 2018 Share Posted February 27, 2018 Not sure how many folks out there doing their prep in colder parts of the world, but I am looking to get an air drier for my media blaster. I get waaaaaay too much water in my pipes. any sugestions or help is greatly appreciated. Thanks RB Link to post Share on other sites
oilshale Posted February 27, 2018 Share Posted February 27, 2018 The supply of dry and clean air is a must for trouble-free operation. Under atmospheric conditions, a cubic meter of compressed air cannot absorb more water vapour than 1 cubic meter of air. For example, if 7 m³ atmospheric air at 6 bar is compressed to 1 m³, 6 parts of water vapour will condense (at constant temperature). When you compress air, a lot of water is precipitated as a droplet and must be sucked off to prevent malfunctions. Without several water traps the dew clogging your abrasive! This is my setup: From right to left: Quick lock coupling, shut-off valve, adjustable pressure regulator with integrated water trap (40µm), branching module with manifold (goes to my air scribe; I need oil free air), two additional water traps (5µm), adjustable pressure regulator for my sand blaster, on-off valve / decompression valve with silencer and a manifold with push in connectors. 1 Link to post Share on other sites

Do you happen to have a parts list (manufacturer etc...) for this setup? Looks like it might be a good DIY option Or did you purchase this system? Link to post Share on other sites

jpc Posted February 28, 2018 Share Posted February 28, 2018 I can't believe you've been doing this for 20 years without an air drier. If I remember when I get home (doubtful) I will try to post a photo of my set-up. Link to post Share on other sites
