Full blast gates (also called cut-offs) are used to open and close branch ducts in a system allowing air to be diverted only to machines that are operating, thus conserving air volume. Half blast gates are used when adding a gate to an existing branch duct that is prone to clogging or a very abrasive material as this gate adds no internal obstructions. Sliding galvanized blade features a locking screw for full volume control including balancing. Ideal for Dust Collection, Fume Venting, and HVAC systems.
