1300 cfm remote blower = too powerful?

10 years ago

My husband and I got the Thermador 1300 cfm remote blower: http://www.thermador.com/cooking/ventilation/vtr1330e-1300-cfm-remote-blower

However, our GC wrote: "I think 1300 CFM is way overkill for the hood . I would really recommend the smaller unit for sound. Your kitchen has 1600 cubic feet the whole room has about 4500 cubic feet of air. Pulling all of the air out of that room every 3 1/2 minutes is overkill . Even on low it will be way noisy. And a waste of heat in the winter ."

Is this true? The appliance store says that 1300 cfm is quieter since it's installed outside. Should we change to 600 or 1000 cfm?

What are you venting? An indoor grill? What is you required Make Up Air ventilation system that you have planned to work with that blower? The system of cooking production, capture and ventilation of the effluent, and the replacement of the air exhausted all has to be planned as a complete inter related SYSTEM. You cannot isolate one portion from it's connectedness to the other portions.

Without even getting too technical, I do think 1,300 CFM is overkill for a 30", 4-burner range. There is more to consider than just the amount of BTU, but as a good rule of thumb for preliminary numbers, you need 1 CFM per 100 BTU. If you have 4 x 18,000 BTU burners = 72,000 BTU => 720 CFM.

The remote blower, regardless of its size, should be quieter than the equivalent integrated unit since it will be further away from where you are standing while cooking.
