Good day,
I was wondering if a venturi (air actuated) vac pump will suffice for pulling 28inHg to evacuate moisture from my A/C system in a project Nissan? I have heard of shadetree mechs using engine vac as well for this task in a pinch. I don't want to rip apart an old fridge nor do I want to shell several hundred bucks out for a decent electric vac pump. Can anyone with experience tell me whether or not these air venturi pumps will work? My compressor in 7HP 70gal with 100% duty cycle so I'm sure it's up to the task for an hour or so. Oh yeah - CFM @ 90 PSI - 10.3 (if that helps)...
Thoughts?
Thanks, Andrew.
