The JET JW1142 is a 4-inch aluminum blast gate designed for use in dust collection and air filtration ducting systems. It functions as a manual flow-control valve, allowing the operator to open or close airflow to individual branch lines in a shop dust collection network. The sliding gate design provides a positive shutoff when closed and full, unobstructed airflow when open. Constructed from aluminum, this blast gate offers durability and resistance to corrosion in workshop environments. It is installed by woodworking shop owners, industrial maintenance technicians, and trade professionals managing shop air quality and dust control systems.
The JW1142 is suited for residential and light commercial workshop dust collection setups where 4-inch duct branches connect individual machines to a central collector. Typical applications include connection points at table saws, jointers, planers, band saws, and other stationary woodworking equipment. It is sold as individual units and is compatible with standard 4-inch diameter duct systems.
Designed as an OEM-style replacement or upgrade component for 4-inch branch lines in residential and light commercial shop dust collection duct systems.
Installation is typically performed by the equipment owner, woodworking shop operator, or a general contractor familiar with shop ventilation systems. Power down and disconnect the dust collector before installing or modifying any duct branch. Secure the blast gate using appropriate clamps, screws, or duct tape rated for dust collection applications. Ensure the gate slides freely before returning the collector to service.
