|What are the technical specs on a Powerbuilt 648532 Vacuum Pump Set?
I recently picked up a Powerbuilt #648532 Vacuum Pump Set. I did not buy this to bleed my brakes but rather to pump out as much C02 and air from my carboys when making wine. The gauge on the unit goes down to -20inHG but I cannot EVER get the pump to go below -17 and this is after repeated pumping. I need it to get down to -20 and beyond to be effective.
What are the technical specs on this unit? Will it only pull a max of -17/-18?
I'll attempt to gather the info for you and get back as I'm not that versed on vacuum technology.
Thanks for asking,
