22 May New FullThrottle Blast Gates for Small Shops, from Woodpeckers
We visited Woodpeckers a few days ago to tell you about their professional quality tapering jig. Now we’re back to announce the launch of the company’s new butterfly valve blast gates that have no grooves to clog up. These gates offer several unique advantages over traditional sliding valves, including more efficient airflow, reduced maintenance, a better fit with quick-change couplers, easier installation of flexible hose, and better mounting options. Inspired by the intake ports on drag car engines, their high-efficiency butterfly valve leaves only a knife edge of the gate to obstruct airflow. And when they’re closed, the pipe is nearly 100% blocked with little risk of debris getting in the way of full closure. Woodpeckers suggest that we “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 but also creates unwanted turbulence.” Plus, typical blast gates have grooves for the gates to slide, and those grooves collect chips to the point that woodworkers often have to fight to get the gate to open or close, and then shut down production to clean them out.
The new FullThrottle gates also offer better mounting options. If the ductwork is ceiling mounted, the gates can be installed with the lever facing down. If it’s wall-mounted, the lever can be placed on either side or on the top or the bottom – whatever is most convenient. If a shop needs to mount the valve directly to the machine, there’s a flange mount available. These options mean that gates can be installed so that they’ll never open when they shouldn’t or vibrate closed in the middle of a job. And if it’s in a tight spot, opening a valve won’t require a full 4-inch clearance beside the duct.
When hoses need to be disconnected ( as in, for example, when a couple of machines have to share a hose, or leaving the hose in place all the time creates a tripping hazard), these gates can be set up for a quick disassembly. They have been designed to mate to just about every 4” quick-connect coupler, so they can have a friction fit. They have a double taper with a 2-inch clamping length (more than twice the clamping area of most other blast gates) and the two tapered sections mean there’s always a good seal. For more permanent installations, there’s a Rack-It bracke Throttle blast gates are made in Strongsville, Ohio. They can be ordered now with special introductory pricing through June 1st, 2021, and are expected to ship late August 2021. There’s a video on YouTube.
