Jun air 6-25 losing pressure
I am currently using a 6-25 jun air in a dental surgery.
I am finding that during longer treatment procedures the pressure seems to drop.
It normally works at 6 bar? When the pressure drops it drops to 2 bar but it's not enough pressure to drive the hand pieces and water does not come through either.
It is at least 10 yrs old.
Had the engineers out and he reckons it's the dental chair - air leaking from the water bottle (admittedly the seal has gone ) but this has been a problem before!
Hope you can help
