JET 4 In. Aluminum Blast Gate

This 4-inch Aluminum Blast Gate manages airflow through your dust collection systems for high-performance suction without unnecessary delays. It measures 4-inches across and works with all standard-sized equipment. Made from durable aluminum, this JET® dust collector blast gate stands up to industrial environments without cracks or warping. It relies on a simple slide mechanism that, when open, allows air to pass from your equipment into the dust collection system and, when closed, forces air away from your unused equipment. Install this aluminum blast gate on every machine in your shop, and you can then increase suction on target equipment by closing off unused suction points. This simple unit works in conjunction with commonly-used equipment and with complex filtration systems, so you never need to disconnect or replace ducts when you want to change tasks.
