Best brand of vacuum pump for ovens


#1

Anyone have any input on what the best option is for vacuum pump for purging shatter, crumble etc is? Been running through $300 bhogart pumps which seems to lose the ability to pull a deep vac over time. Is there a more expensive but more effective option? Thx

At that rate you can get$50 eBay pump and keep the oil changed it’ll last way longer… You can get 6 for the price one, one year that’s long time! I have hard time killing mine!

They pull the same just slower … But cheap 2stage would be the way too unless u have to get name brand!

I’ve done the same. I also started using one of my chemical duty welch pumps, over time that needs a rebuild as well.

I have the Ai cold trap now and am going to hook an edwards 30 up to it and see how it works! I’m thinking just change the oil biweekly with the cold trap and it will hopefully work for a while. The eddy could use a rebuild but still pulls very deep
