Oh, Ok thanks, that's interesting. I was looking at it backwards. I was thinking that it had to work harder to try to pull the air through. Now that you mention it I remember people talking about worrying about burning out motors when exhausting outside.
Is a shop vac the opposite? I was also thinking they get burned out if there is not enough air flow.
If, when this happens to anyone, it's really important to take your time cleaning the canister to avoid damaging the paper filter.
Been there (not quite that bad but close), so go slow and be gentle. Those babies are expensive!
After you get the 'cake' off, a paint brush is your friend.
Jason, I would go for 0-4 inches/water as ideal, up to 0-8 inches. More than that puts you too far down on the bottom of the measurement range.
Cheers

Jason, some shop vacs use the airflow for cooling as well, these can be damaged by no airflow. Not to mention most have a very high rpm brushed universal motor instead of induction motor. Think router table vs shaper.

Got it, thanks a lot Sean.

It connected to the fan exhaust elbow via a piece of 1/“ tubing, the other port on the manometer is open.
You can make a manometer with a piece of clear tubing in a U shape, filled with coloured water.Regards, Rod
