Definitely happy with these muffins. They are my first few runs. I expect improvement with more runs.

Robinair makes a decent pump and 8cfm is certainly a handy size. You don't need a two stage, but it will work fine. We use a Robinair 15500 5 cfm two stage for some of our stuff.

I was just about to order the 15500 Robinair but a few negative reviews on amazon stopped me (like oil smoke and only reaching 25hg). My current gast pump quit pulling 29hg and I'm looking for a reliable 2-stage and not break the bank, I'm only using a vac it pro, do you think I'll be fine with the 15500?

the 15500 is such over kill, even a stage 2 pump is overkill. 29" is plenty of vacuum to be working with.

I respect your opinion VP, what would your recommendation be for a pump to do the job just fine in my vac it pro chamber. My current pumps only go to 25hg. Thanks in advance

just something fairly cheap, should only have to spend 100$ or so... those 500$ pumps are way overkill and just wasting money for making BHO.

what is your elevation?? have you tried changing your pumps oil? are you sure there isnt an air leak anywhere? sometimes even just a 98% vacuum is the best. at a 99.5% vacuum, THC will boil away at something crazy low like 10 or 15F.

I have had awesome results with a cheap chinese no name one from harbor freight.

I'm around 2000 ft elevation. These pumps I have I am not sure that you can oil them, they're not typical vacuum pumps, I don't know what the hell they were used for but they were in my boat storage space being thrown away. I really try to avoid harbor freight, Mainly I hate going to that side of town, it's a full day trip. I was looking at the 15300 Robinair for 150$ @ amazon

well if its that cheap, I would get it. I thought those robinairs were like 400+ I paid 110$ for my no name chinese one.... so hell yeah if its only 150$

Okay cool, thanks for the solid advice man. Loving the help here at RIU!

i think mine was 150 or 160 with tax, i agree i think anything over 250 is over kill

also, if youre at 2000 feet, same as me, max vacuum you can pull is 28.7 or so. so your gauge will never go past 28.5 ish... but thats a full vacuum... so once your gauge is at 28" that would be roughly enough and I wouldnt panic if youre only seeing 28"

25" is a hair low though.

I just ordered it, 113$ after my amazon points and shipping, I'm stoked to say the least! Yeah I don't think I could justify paying twice that either, it's nice and all but 200-250$ is a decent amount of product that I can use! Good to know that the gauge won't go to 29 because of altitude, I would have been scratching my head on that one for awhile

yeah were already at like a 1.2" vacuum @ 2000 feet... so we pull 28.7 more and theres your 29.9"

thats a hell of a price, I didnt know amazon did points. pretty cool.

on ebay $75 to ur door .... Single Stage 3 CFM 1/4HP Rotary Vane Vacuum Pump

I'm not a huge fan of eBay, had a few bad experiences with sellers a long time ago. I buy a lot of crap off amazon and I finally decided to cash in my reward points. You get like a dollar for every hundred you spend or something....

i am not a huge fan of buying stuff online, plus i got a 3 year warranty if it fucks up, which it has, i get a new one from the store that day. no sending it back because these fuckers are heavy

Trust me twitch I would like to buy locally but I don't drive, I might kill someone trying too! I have found that it is easier on my wife and I to order online than to drive around town for most the shopping

yeah ordering online is the best thing ive ever done... and worst thing on my bank account. need something? anything, some random crazy weird piece.. find it in 2 minutes, pay tonight and have it shipped in the morning, providing shipping isnt a deal breaker, and you can afford to wait a week or so. I love it!!!! especially being in canada... your guys' prices in the states are fucking lowww!!! like 40% off everything, or more.

I'm about to buy equipment, probably going to get the robinair 15300 I guess... what is a good vacuum chamber, and do I need anything else for it like gauges or hoses or anything?
