Commercial catering make up air ....

[dav]

Could anyone navigate me in the right direction . how do you relate the free area of a make up air grille with the extraction flow rate of a commercial catering hood , or how do you calculate how much air will pass through a make up air grille in a commercial kitchen . its just its somthing i dont know much about . ive even asked comcat 1, 2 and 3 engineers and they say its a specialised subject . i know the 85 % mechanical make up air rule , but not sure how to apply .....cheers

You should contact a commercial ventilation/extraction company, there are plenty in the yellow pages, i'm sure they can help.

if you have comcat you should know this!!!!
The mechanical ventilation is measured by cubic meters per hour and will be relevant to kw rating of the appliances
and dont forget about you interlocks!
