I never had an air compressor. When I first saw a DIY project about making one out of a used fridge compressor, I started to collect the required components to make one myself. I found a 1/5 hp fridge compressor from an old refrigerator. A friend found for me a 7.5lt used extinguisher. I spent some time reading articles about converting a fridge compressor to air compressor and finally, I picked up the design I thought it was most convenient and practical, made some changes and finally did it.
