    I use a JB 10 cfm. Keep the oil clean and it'll work great for a long time.

    Wanna say myself and other guys have been using a a Robinair pump. Silver body red plastic handles. I've had mine for about 8yrs other guys always break the plastic handles. Boss has a Jb, he always gets the good stuffs(even if he doesn't use it) Only complaint is filling it and maybe same across other brands and apprentices.

    Edit: Had to cut the end off power cord, from wrapping it around pump. But, that could happen to any brand.

    I've been using a YJ 6 cfm for about 12 years. I know there are better pumps out there but it stills pulls well.

    Thanks guys I will probably pick up a JB platinum. My old pump had the ballast and I used it. I don't think the other guys at the shop know the ballast exists. It's mostly turn on the pump and walk away.

    Shop gave me 2 YJ 8 CFM pumps. No complaints.
    Have a JB 6 at home that works well and seems quieter and lighter then the YJs

    JB dv-200n...

    Only vacuum pump I have ever had in my 17 years in the trade. I bought it in '98 and it's still running today. Best $245 I ever spent.

    The biggest difference maker for me was adding a YJ tree to the 3/8 outlet of my pump along with 2 1/2" hoses and vcr's. I've been more than pleased with the results with just a 6 cfm pump. Granted I don't work on anything larger than a 25T but it made a huge improvement.

    What vacuum pump are you using

    I have a YJ Super Evac 8cfm. Brand new zero complaints. My last pump was 15+ yrs old. Same kind just a 6cfm. Still runs like a champ. I will say that when I switched to the 8cfm I also changed to 1/2" hoses with vcrt's. Can't say anything about the 6cfm set up that way. But my 8cfm rocks.

    I am watching a tez8 on eBay also. Maybe I will maybe I won't.

    20 CFM. Got her used for cheap, but she's still got some good years left. Just change the oil regularly.

    With my setup I pulled a 20T carrier down in about 30 minutes. That was both circuits to just under 300 simultaneously. I know a larger pump would fair better but I'm not sure if it would justify the cost to how much faster it would be.
    I've eyeballed that Appion for a while for the ease of oil swaps. Cost versus added performance has kept me at bay.

    I agree. I've heard how mechanically it's different and I understand and get it. BUT I have a hard time swallowing the price tag. Yes the oil changes are nice and it would take 1/3 the oil my super evac uses but still. If I find something in eBay then maybe. Would depend on my mood I guess. My only true reason for buying another pump was the age. Just didn't want to find myself in a situation where it went down and I needed it. Just an FYI I believe I paid around $450 out the door at RE Michaels. They were the lowest price. But I could of bought two for the price of the tez.

    I still have a Robinair blue for a backup. My superevac is 12yrs old or so now. Is the performance jump to 8 cfm worth making the upgrade over what I'm currently using? I know it is faster but is it enough to justify until my 6 starts giving up a bit?

    I went out to commission a system my guys put in last week. 4 ton split straight AC. 7/8"x3/8" line set about 45' in length. Now mind you they leave the drier out until the system is evacuated the last and final time. (Fill system with nitro break vacuum and braze in drier) anyways. First time I hooked up to system had it below 500 in literally a minute. Second time with broken vacuum via nitro had it below 200 in just over 2 mins. Final pull it held at 130 I believe. Now mind you I use 2 half inch hoses with vcrts and it was a new system so no oil to boil off but I have been impressed. Again I never tried my old pump with half inch hoses. It is a 32lb pump though. The tez is 28lbs. I do a lot of rtu work and could justify it if the price was right. Also having the multiple hose size taps on the tez would be nice.
