I dont' work with vent a hoods much and would like to know more about them.
I know there's not alot to them, but I figure the more I know the better tech I'll be.
DOes anyone know where I can find info about checking the CFM through a vent a hood system?
I'm wanting to know how to check CFM so I dont' have a major positive/negative pressure on building.
Especially if I question wether someone has tinkered with split sheaves on the blower motors pulley.
