Re: Super Sucker Vacum Questions
I've been using a Robinair (sp?) 5.7 cfm vacuum pump (for auto A/C) for over a year now w/VO. I used some 134a conversion fittings on my vacuum vessels - they screw on to a flare fitting (1/4" i think?). This gives me quick connectability using the A/C gauges and I can still use my pump to work on auto A/C systems.
Lots of folks use salvage refrigerator pumps, cause they're (disposably) cheap and apparently get the job done. I've seen new off-brand auto a/c vac pumps as low as $45. The higher the cfm, the faster it'll pull down.
I use my vac pump for collection, transfer and occasionally dewatering - it works well for all of these. It'll pull a 40 gal h2o heater down to 24+ in.hg. in 20 min or less. This will collect almost 35 gallons of VO thru a 3/4" ID hose in under 5 min.
Change the vac oil frequently to avoid moisture contamination issues.
I'm looking for a FREE 250+ gal propane tank close to home right now. I'll put it on a skid that I can load/unload onto my truck w/forks on the tractor - I don't wanna mess w/a trailer cause of where I gotta go for VO...
