4" Dust Collection Blast Gate Self Cleaning ABS
This version of our blast gates has a built-in wall mounting bracket to allow secure anchoring to the wall to prevent sloppy opening and closing. Blast gates are used to open and close branch ducts to divert airflow only to those machines in operation. This conserves air volume and keeps suction strongest where dust is being produced, thus maximizing dust extraction. These ABS plastic blast gates are very economically priced to allow you to outfit your dust collection system for maximum performance. These fittings are abrasion resistant and are designed to withstand the abrasive nature of wood chips and saw dust. Due to the potential for built up of static electricity, it is recommended that all dust collection systems with plastic fittings be properly grounded. The gate slides completely through the housing which is self-cleaning and eliminates chip build up. Both openings are 1.25" long and taper from 3.85" to 4" and will fit 4" flexible hose or tapered dust fittings. Made from strong 1/8" thick abrasion resistant ABS plastic. Has a built-in stop to prevent the sliding plate from coming out of housing.
