How much pressure (Bar)
Hi! As I’m installing a new compressor in my dental unit, I will need to know at what pressure my chair should work. Can’t find the information in this manual. Thank you in advance.Reply

No water pressure to assistant side

For an A-dec Cascade delivery system:

Have examined components but cannot determine what is causing the low pressure on the assistant side air/water syringe. I have ruled out the handpiece and any handpiece accessories. 40 PSI is coming out of floor box pressure gauge.
