30" Range Hood Info and Recs

[sine]

What are you doing on the range? I'll have one pot at a rolling boil for pasta, not four.

My wife wanted to start cooking with a wok.

Last Saturday we purchased some awesome cuts of beef from a small local market on the south shore of NC.....with the big vent at full blast our neighbors could breath in the awesomeness.

Honestly, I have no idea if the vent (we have proper spec, solidly mounted duct/big ext flapper) we have pulls 1200cfm (highest setting) but for an island venthood it works reasonably well.

Just a further word and data point about some of the HUGE airflows casually mentioned in this thread.

The 2015 International Mechanical Code, under Chapter 5, Section 505 Domestic Kitchen Exhaust Equipment, states:

505.2 Makeup air required.

Exhaust hood systems capable of exhausting in excess of 400 cfm (0.19 m³/s) shall be provided with makeup air at a rate approximately equal to the exhaust air rate. Such makeup air systems shall be equipped with a means of closure and shall be automatically controlled to start and operate simultaneously with the exhaust system.

Let's be careful out there, TH.

Hence our 400cfm fan.
I don't do makeup.
