I bought a brand new air tech oil cooled L21 in Vernoa at the maple conference. After 20 hours of use it has seized up.
Big runs are coming this week and I have 2 options to run on my 800 tap bush:
1. Run my steady SP-11 which will pull 17-20" as long as I am tight
2. Run this new Dry Vane Rotary gast pump that I just picked up Friday. NIght. It runs good so far and has a lot more CFM. I turned it on in the frozed woods today and the pressure shot up.

Here is the link to the side for a new one. Mine has been sitting around for a while but has the same exact spec. (right down to the glass jars)
This would allow me to use my SP - 11 on my bush of 175. The Gast would be big time overkill. and is too loud in the residential area the a big generator cranking.
I guess my question is does anyone have any experience with these Gast Dry vane pumps and are the reliable?
Any input is appreciated. Thanks
Chris
