Making the ds50 a bit more modern

Les,

On this 519, I'm seeing the aftermarket wide green wheels on the Classic Omega/Heritage I front axle, and the first style (smooth) Tradition wheels in the back. Thank you for the compliments about me and my one-time D80 fix!

Mini-emptor setup I've never seen before?

Check out this link. It's for a DS50 without the original emptor. This doesn't look like a mini-emptor and it's made out of green plastic, so what the heck is it? Has anyone ever seen something like this?

those F&G's are functional and easy to put on, but others on this board have tested the cfm and there was a notable loss in airflow, though I"m not entirely sure as to why this occurs.  When the vac is 'on' and the handle is retracted back (in normal use in your hand), the severe 'kink' of the airway I alleviated, but when stationary and handle at full upright position, the air tube is worse than a 'L' pathway.
 
Here’s what I’m talking about

See the sever ‘crimp’? See how it opens up whene handle retracts? Some royal uprights have the same issue. Anyone know why airflow is reportedly so reduced with these bags?

Hey

Hey
I think not positive it a 90 degree bend on the setup. Natural air flow say 115 cfm it's going to hit turbulence and cause back pressure.
I believe the emtors help with air already in place other air goes around so only backlog is just at startup.
If someone else onery is his sign on. He put 2 PVC 45s making f and g setup for shakeout. I believe it was his model 215 royal. If you applied more tubes idk it would help but his motor was only 3 or 4 amp so airflow was not as high.
The tests I did ranged from 30-45% loss of power using f and g on my 4 amp 562 motor with amodel fan. If you do anything shakeout is better than f and g. The loss is around the 90 degree turn but also the f and g bag the pocket to hole is quite long and air is lost and it strains the motor so much. It kinda like running motor on high speed it's programmed to do 4amps. Your wearing out carbon brushes and coil vacuum may overheat.

I don't follow your logic Les,    once the vac is turned on and handle leans back , the 90-110 degree issue looks to be reduced to maybe 30% bend.  'pocket to hole'??  not sure what that is, but the pathway for air coming out of the exhaust...to F&G opening....the tube passageway can't cause air loss or pressure....its way shorter than the kirby fill tube.     oh well, just wondering..
 
Hey

On f@g setup the emtor or exhaust is level at 0degrees. The f@g when outer bag is put in clip it's 90 degrees straight up. May it be bag or where ever the area bag catches degree is mid to upper bag in 90 degree fashion. The reason Kirby had better airflow there is no bend if there is it's maybe 15 degrees. And it has solid air path inside hose. The f&g path is through long section of bag to get to was the waste area of the bag.
You were right I didn't explain well. The eureka and sanitairre don't loose pressure as vacuum chamber is right there. Royal designs there vacuums with deeper fans some use f&g but newer are top fill and I have a 880 I'm going to test the difference between top fill and f@g. There will be a difference I'll find out how much.
I have done Kirby f&g shakeout and HEPA sysrem. The f@g and the shakeout cfm was affected. The more that was in shake out the bigger the difference.
