Air curtains in commercial kitchens
Air curtains in commercial kitchens
(OP)
Designing a new commercial kitchen with multiple grease hoods.
Got a review comment stating the need for an air curtain (to prevent insects from entering) above the 3' side door. I assume this door would be used for supply loading, so it may be open for somewhat extended periods of time. My question, is an air curtain necessary? I dont' particulary think so, and am somewhat worried that its high velocity air stream could disrupt the capture under the kitchen hood.
I'm leaning toward rejecting the comment, and not providing the insect air curtain.
Any thoughts?
Thanks.

1- How close is the back (delivery) door to the exhaust hood?
2- I have been told that about 1/2 of the cfm, air from the curtain could come inside the conditioned space, so if this is true you may have to acount for it.
3- How is the air supplied to the curtain? Is it just outside air?
Hope some others with more experience can help on this design.

As far as operation, all of the ones that I have seen and used, mount on the inside of the door and just recirculate the air in the space. They operate off of a door trigger switch and only operate when the door is open.
The best advice would be that of Symiedpiper and call your local air curtain rep. I would suggest calling the hood manufacturer as well if you are concerned about disrupting the hoods functionality.
