QF Y Branch 90°

Nordfab manufactures ducting for use in dust, mist, and fume collection systems.

QF Y Branches are standard with QF rolled ends, allowing quick connections with other QF ductwork. Nordfab QF® duct branches in Y shape (sometimes called “true wyes”) are also available with 60º angle between legs.

When ordering, specify, specify material; gauge (if nonstandard); dimensions A, B, C; end styles if not all QF; and angle (90° shown below, 60° also available).
Both B & C each must be at least 50% of A, with B or C being at least 80% of the opposite leg.
Use the following formula to determine length: L = A + 4"
Available in galvanized steel and 304SS (as shown below) or optional 316SS or carbon steel
Available with flanged ends in diameters up to 72", and other various end types
Available with 60° angle
Optional gauges 18, 16, 14, 12 and 10
QF Y Branches are a Nordfab Now^® product so items in the most commonly used sizes and material are in stock and can typically be shipped the day after order placement.

Contact Nordfab or your local Nordfab dealer for assistance with optional end types, larger sizes, and material / gauge options.
