I have 3 shop compressors which I built from purchased and salvaged components.When I worked at Orenda Aerospace the pneumatic HVAC system was decommissioned in favour of a centralized building management system. Each building and department had its own air receiver, employees were given first chance at salvage before the scrappers came in, I managed to get 3 tanks. Over the years I purchased 3 pumps, 3 press. switches and 2 motors. The rest is mostly salvage and stuff I had around the shops.
The first pic. is my garage/workshop compressor, its 3 HP and puts out tons of air.
The 2nd pic. is my heated shops compressor, its 1.5 HP .
The 3rd pic is my outdoor equipment shed compressor. I built this one shortly after building this place to maintain my vehicles and outdoor equipment some 15 years ago. It has a salvaged 3/4 HP motor and has served me well for those 15 years. It now needs a good cleaning belt guard and paint job.
Cheers
