Main highlights

•When creating or adding to our dust collection system, there are a great many details we need to keep in mind. Typically, we will have one dust collector connected to multiple machines around the shop. While this kind of works, it can work much better if you could turn off the airflow to all the machines except for the one being used at the moment. That’s where blastgates step in. Simply open or close the blastgate to allow or block airflow to a specific machine
•Ideally, the way blastgates should work, is that you should have a blastgate setup for every machine in your workshop. When you close all the blastgates to all the other machines, you increase the airflow or suction to the machine being used. This means that you should see less dust on the machine that is being used since it is getting maximum airflow or suction. This also helps reduce the amount of wear and tear on your dust collector.
•This blastgate features tapered ports on both sides of the blastgate. The tapered ports allow hoses (sold separately) to be slipped on and clamped with hose clamps (sold separately) with ease. Tapered ports will also accept some tapered fittings.
•The sliding gate has a built-in stop so it will not slide out when fully opened. The gate acts like a shut off valve to keep air from flowing in a given direction when it is closed. When opened, air will pass through allowing dust to be collected as needed.
•The Fulton blastgate is made from a durable ABS plastic material for everyday workshop use. With an easy to open and close sliding gate you’ll be able to quickly open and close hose lines to concentrate airflow to where you need, when you need it and for maximum airflow.
