Questions about this size
How many CFM does a 22" round duct carry?
About 1,850 CFM at 700 fpm and 2,375 CFM at 900 fpm. A 22" round duct has 2.64 sq ft of free area, and airflow is free area times air velocity, so multiply 2.64 by the velocity your design calls for.
What is the free area of a 22" round duct?
2.64 sq ft, or 380.1 square inches (pi x diameter squared / 4). Its circumference is 69.1", which is the width of sheet rolled to make it before the seam allowance.
What gauge is a 22" round duct made in?
22-gauge galvanized steel. PMX picks the gauge from the distance around the largest opening: a 22" round duct is 69.1" around, and openings that measure over 54" up to 84" around are built in 22 gauge. The configurator on this page lets you choose 26, 24, 22 or 20 gauge and re-prices it.
How much does a 22" round duct cost?
$63.27 as configured on this page: 22-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 $112.02 in aluminum and $160.77 in stainless steel. In galvanized steel, the 12" long version is $55.04, the 36" long version is $71.51, the 48" long version is $79.75, the 60" long version is $96.11.
Can I order a round duct 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 22" round duct 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.
