Using HVAC pump for vacuum bagging (doubts)
Posted: Wed Sep 19, 2012 3:07 pm
I recently bought a second hand HVAC pump for repairing compsand boards. It's a Wigam DIP 402EV and it pulls a very decent vacuum, so much so that i have to have a valve and let air into the system to regulate the vacuum.
The problem is that these pumps are not made for pulling air and they start burning oil. Does anyone have experience with using these pumps for vaccum bagging and tell me if they can they keep on working for the time it takes the resin to set?
