Hi IrStuff

This is for a restaurant.

thanks

RE: Typical air stream temperature of a Kitchen Hood

I think you will have to be a little more specific about what is under the hood.
 Is this a hood over a range where you will need a grease duct, or is it over an area where only cooking pots for boiling vegetables are used, which does not require a grease duct?
B.E.

RE: Typical air stream temperature of a Kitchen Hood

Normal Grease exhaust is about 110F - 140F. When selecting a fan, it is best to select a fan that has a max operating temp of at least 250F. This will allow the fan to operate in the event of a fire.

RE: Typical air stream temperature of a Kitchen Hood

To work it out find out the gas supply to the cookers, convert it to energy, and calculate the temperature rise using the kitchen exhaust rate.

Quick calc on a typical exhaust hood indicates about a 10 oC temperature rise.

This would be a worst case steady state scenario, but might be exceeded if there is a flare up when cooking.
