Don't let these guy talk it down.
SELLING POINTS
1.) Less oil
2.) Quick clean oil change that you can see as it gets dirty.
3.) Carry multiple oil change outs with you in small sealed bottles instead of one big jug
4.) trash collector on intake
5.) Several size pipe connections. Not just one or two.
6.) This to me is the big one.
REBUILD KITS and it can easily be done in the field. That means when it gets old....you rebuild it instead of buying a whole new unit.
7.) Very reliable.
8.) You don't get oil all over the back while the foam handle slips off.
The reason the other guys don't like the TEZ8 is because they didn't go the extra step and buy the
Megoflow Speed Kit which does make a huge difference. Yes, this kit works on other vacuum pumps but is designed for the TEZ8.
I strongly recommend the Megaflow Speed Kit. I can pull a 300 micron vacuum on a 5 ton split-system in under 10 minutes with my TEZ8 and Megaflow. I usually do chiller work or 10 ton plus and have been able to vacuum one circuit of a 100 ton air-cooled chiller to 430 microns in 1 hour 20 minutes.
