4" dia. - Self-cleaning Manual Blast Gate - Industrial Grade
BLUEFIN, Self-cleaning full blast gates (also called cut-offs or waste gates) 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. Sliding galvanized blade features a
locking screw for full volume control including balancing. Bluefin manual self-cleaning gates are sand-cast high quality industrial grade.
Self-cleaning gates are the same construction as our full blast gates except the galvanized steel slide moves through the open end to push out debris from wood pulp and sticky materials.
