Just measured the compressor suction- 94Kpa = 705 mmHg = 27.7 inHg= 0.927 Atmospheres , not bad for an old sucker

Now i still have the problem about the compressor switching off after 15-20 min of run, without obvious heating. Any ideas? I am going to use the bigger compressor when repaired the gasket, but i want already to use my fixtures . I read on forums people use 8h non stop the compressor without problems for years, why then this old sucker stops?


By the way i have 2 more micro digital vacuum switches, i bought a lot, used , perfect condition, made in japan, very small size, so PM if interested. 25euro each
