Description
This is my design of 3d printed housing for old fridge compressor - it has integrated pressure regulator, manometer, safety valve, cooling fan and air filter. I checked on several compressor models with the same mounting hole spacing (170 x 70) and they also fit, so you can say that the housing is quite universal.
Due to the components used, the maximum output pressure is ~10 bar. As you may know, fridge compressors have a problem with oily air at the output. After testing, I can say that the air filter removes most of the oil, but for more demanding purposes, additional filtration is still necessary.
