发帖数: 5043 | 4 Diameter of your Range Hood Ductwork is the most important factor
The diameter of your Ductwork is the single most important consideration.
Here are some guidelines based on your Range Hood or Vent Hood CFM. Now
please note that we will use the most commonly available sizes of Ductwork
for our recommendations and that in many remodel applications for older
homes there is an existing 4” Duct which in some cases is the only option
other than a recirculating hood. We always recommend venting outside over
recirculating even if you must adapt to an existing smaller duct size than
is recommended. If you have any questions please call us or contact your
local HVAC professional.
0-400 CFM Minimum Duct Size of 4” Recommended Duct Size of 6” if possible
401-600 CFM Minimum Duct Size of 6” with a Recommended Duct Size of 8” if
possible
601-900 CFM Minimum Duct Size of 7” with a Recommended Duct Size of 8”-10
” if possible
901-1200 CFM Minimum Duct Size of 8” with a Recommended Duct Size of 10”-
12” if possible
1200 CFM and above will depend on the motor type and duct run length but at
least a 10” diameter duct is required and 12” is recommended.
The recommendations for Range Hood Ductwork Size are suggestions. After you
consider the size of your Ductwork the next most important factor is the “
Run”. How long is the the ductwork and how hard will the Range Hood Blower
have to “push” the exhaust air to get it out of ductwork.
