Sizing a make up air system question

[Gib's Son]

Will be no worse that the usual dirty corroded metal filters normally found in the make up's.

Yeah, you got me there. Just be careful delving into areas you are unfamiliar; there are many code issues with kitchens.

And no one mentioned that the MUA needs to be tied into the supression system, so that if the system activates the MUA shuts down. If not you add air to the fire.

If he can afford it get the hoods that have VFD's on the fans that ramp up and down based upon heat and amounts of smoke passing through...those are sweet.

Who sells these sweet hoods? I can't find them at Greenheck or at Captiveaire. Sounds like a custom set-up.Have you ever set one of these up?

Greenheck does offer them. The controls are mfg. by Melink.The system works well if there are low periods of activity on the cook line during slow times of the day.

The Melink set-up is "sweet", will definently steer a new install in that direction. Thanks for the tip.
