Scott had a problem. He was sick and tired of spending perfectly good money on cans of compressed air to clean his computer equipment. Air is free, and once you have the can, it should be easy to refill, right? In this build log, with parts list and instructions, Scott details how he made his own refillable can using an old Oust can, an emergency tire inflator and a few zip ties. The compressor he used wasn’t powerful enough to get the internal pressure up over 50 PSI…but most cans are rated for around 200-250 PSI, and at least this way, Scott can be confident his project won’t unexpectedly “turn into a frag grenade.” Check out his plans here, or buy a ready-made refillable air can here or here.
