Someone posted the orifice diameters for the SF 600 a while back. Any idea where that post is located?
Thanks

Not sure what you are referring to in your post.
The SF 300 Bench has 6 ranges with the diameters as posted.
It has 6 115923 motors. 25, 50, 100, 200, 300, 400.
The SF 600 uses the same diameters but with 1.91 SG blue fluid
which raises the cfm by 50 percent. 37.5, 75, 150, 300, 450, 600.
and uses 8 115923 motors.
The SF 1200 uses two of the same orifice sizes as the SF 300 (200
and 400 cfm) and a larger 600 cfm orifice designed for the .826 fluid.
They open more than one orifice to increase flow (using stoppers).
Max cfm is 1200 cfm. I have added a 100 cfm orifice in a couple of benches to narrow the ranges and to get 1300 cfm max.
I really like the SF-1200 orifice/ stopper design with the 4 orifices but
the bench is POWER HUNGRY. It uses 16 115923 motors.
Hope this helps.
