Hi Everyone,
I wondering if I can use so a vacuum pump I already have for working on automotive AC systems to push air a compost tea set-up. I'd like to minimize the purchase of extra stuff, especially if I have something that can already fit the bill. I am concerned about the following, of which I would appreciate any input:
A. Premature wear (I would want to run this for 72 hours at a time)
B. Pump oil contamination – this pump is designed to exhausts oil. I think it’s only mineral oil but am concerned if that would be harmful to introduce to the compost tea
C. AC Refrigerant – This pump previously pulled a vacuum on a
R134A system (MSDS sheet linked). I think it would be safe to use as any remnant 134A refrigerant would be negligible.
Thanks in advance for your input!
