Hello guys, can someone point me with this problem.

On my vacuum pump is written something like this:




"enddruck"/"ultimate vacuum"  = 150mBar

What doest it mean, how its to 30HG or -1 BAR ?




anyone know?

When i check pump with gauge its shows -0,2 bar.. SO im not sure if this is max of this pump and 150mBar means equal 0,2BAR or pump is broken..

sorry for my english

If I'm correct mBar goes from 0 (full vacuum) till atmospheric pressure (1040-1070)

this means you can achieve a +/- 87,5% vacuum.

Correct me if I'm wrong Smile
