![]() ![]() I do not provide any dimensions as those are not critical and you can use bits and pieces. Put them on a cookie sheet and bake in oven to recharge. I like the blue because they change color to pink when exhausted. You can get them on eBay or perhaps a local store that sells supplies and tools related to air compressors and spray painting. Keep it out of sunlight too as UV will really destroy PVC in time!ĭesiccant beads: I bought a 5 pound can of blue indication type on Amazon. It is suggested you build a nice, pretty ( or not) housing to act as shield.just in case. PVC if stressed will not stretch, it will EXPLODE sending shrapnel in all directions. Most sandblasting and spray painting jobs won't need that much pressure anyway. While the over all pressure rating is about 250 psi, I suggest you limit to maximum 120 psi for safety. I filed a bit of a taper on the 1/2" pipe to make it easier to align when rejoining the sections. The center air tube I glued into the bottom separator but you MUST leave it free at the top so it can be removed to change beads. Instead of the built in funnel to add desiccant, I made the whole tube unscrew from the tee for recharging. rather than two tees and two reservoirs I stacked them. The principle is same as in Hanna's YouTube but simplified. ![]() I did not want to wait! but I may modify mine later. Short sections can be purchased on eBay for under $20. If you want to get all fancy, replace the PVC with clear schedule 40 PVC so you can see the color of the beads. The design can easily be expanded to 3" PVC if you want higher capacity or less frequent bead changes. Materials consist primarily of 2" schedule 40 PVC water pipe with a few other fittings and bits thrown in. The first image has pretty much everything you need to know. ![]() I wanted something effective but a bit smaller. I saw a YouTube video by " Hanna's Bug" Amazing young teen girl who does it all! who had made something similar but twice the size. This will make sandblasting and painting much easier! You can purchase commercial dryers, which I did, but it was small and took little time before the desiccant was exhausted. ![]()
