5x Woodpecker Full Throttle Blast Gates For 4” Dust Hoses

Up for sale are 5 blast gates which work with 4” dust hoses. I’ve used them for about 3 months before upgrading my dust collector to a 6” hose. These currently are priced at $21.99 on Woodpecker site. DESCRIPTION FULLThrottle™ Blast Gate Efficient Airflow Inspired by the intake ports on top-fuel dragsters (where airflow restrictions are the difference between winning and losing), our engineers designed a high-efficiency butterfly valve. When the valve is open there’s only the knife edge of the gate obstructing airflow and when it’s closed, it is nearly 100% blocked with little risk of debris getting in the way of full closure. Look inside the typical steel or plastic sliding gate and you’ll see a large portion of the airway blocked by the part of the gate that doesn’t get out of the way. This not only restricts airflow, it also creates unwanted turbulence. Reduced Maintenance Typical blast gates have grooves for the gates to slide in. Those grooves collect chips like a magnet. Soon you have to fight the gate open and closed or stop everything and clean them out. FULLThrottle’s butterfly design eliminates the groove and the cleaning that goes with it.
