Hi guys, I have a blue vac mk120ds, it should have an ultimate vacuum of 0.03psi (0,02mbar/15microns), it’s been working perfectly fine for the past 12months, however it’s suddenly lost a lot vacuum and now it only reaches 2.29psi !
I have changed the oil in the pump, which did not fix the issue. What else could be causing this issue?
Thanks
