Mike, here is a url to the manual for the gun.
This is a url to the turbine I got.
http://www.lambelectric.com/support/prod/11676500.pdf It's a 3-Stage
Tangential Bypass model
Got both the turbine and gun on ebay. The turbine quite cheaply. I
started the turbine up today with 25 feet of 3/4 inch hose on the
outlet. Even without the gun on the end of the hose I was very
suprised at how much air was lost compared to just the outlet of the
turbine unit itself. I've no experience to determine if it is enough
air and decided not to try and spray anything at this time as a couple
of weaknesses in my construction became immediately apparent and I
didn't want to damage the turbine. I will remedy these next week and
try again. I need to secure the PVC adapters I used to adapt the
turbine outlet to the 3/4 inch hose connector. And I need to redesign
how the turbine is mounted to eliminate deformation of the turbine
housing. If results are acceptable I'll post some pics.
