Airflow by velocity
| Air velocity | Trunk (1.17 sq ft) | Branch (0.25 sq ft) |
|---|---|---|
| 600 fpm | 700 CFM | 150 CFM |
| 700 fpm | 815 CFM | 175 CFM |
| 900 fpm | 1,050 CFM | 225 CFM |
| 1,200 fpm | 1,400 CFM | 300 CFM |
Airflow is free area times air velocity. Pick the row that matches the velocity your design uses; these figures are capacity at that velocity, not a pressure-loss calculation.
Questions about this size
How many CFM does a 14" x 12" tee with a 6" x 6" branch carry?
About 815 CFM at 700 fpm and 1,050 CFM at 900 fpm. The 14" x 12" trunk has 1.17 sq ft of free area, and airflow is free area times air velocity, so multiply 1.17 by the velocity your design calls for.
How much air does the 6" x 6" branch take from a 14" x 12" trunk?
The branch opening has 0.25 sq ft of free area, 21% of the trunk's 1.17 sq ft. At the same velocity in both, that is about 175 of every 815 CFM in the trunk at 700 fpm. The real split depends on the duct system downstream and on balancing dampers.
What gauge is a 14" x 12" tee with a 6" x 6" branch made in?
24-gauge galvanized steel. PMX picks the gauge from the distance around the largest opening: the 14" x 12" trunk is 52" around, and openings that measure over 30" up to 54" around are built in 24 gauge. The configurator on this page lets you choose 26, 24, 22 or 20 gauge and re-prices it.
How much does a 14" x 12" tee with a 6" x 6" branch cost?
$87.26 as configured on this page: 24-gauge galvanized steel, made to order. The price comes from the same quoting engine that prices the cart, and changing any dimension in the configurator re-prices it. The same size is $129.51 in aluminum and $171.76 in stainless steel.
Can I order a duct tee in a different size?
Yes. This page is one published size; the configurator above is loaded with these dimensions and every one of them can be changed to the size you measured, in galvanized steel, aluminum or stainless steel. Each fitting is cut and formed for the order in Pittsburgh, PA.
How fast does a 14" x 12" tee with a 6" x 6" branch ship, and can it be returned?
It ships in 1 business day from our Pittsburgh, PA shop, by UPS or by LTL freight for large orders, anywhere in the continental US. Shipping is calculated at checkout from the order's weight and destination. Because it is made to the dimensions you order, it is not returnable.
