Jet JW1007 4-Inch Blastgate

 (15 customer reviews)

With a blastgate at each machine, you can control the air flow from the DC unit as if you only had one machine hooked up, providing the most efficient use of the air suction. By opening and closing each blastgate, as needed, you will get the maximum amount of air flow at all times. For a more "durable" blastgate, there is a metal version available at a premium. But I have found the plastic gates run into problems with use. They jam with debris and cannot be taken apart to clean. The spot welds, which hold them together, will lossen with use, then the sliding gate, which is a friction function, will not operate properly. The metal gate uses a screw to kept the gate open.Overall, it is a needed product that allows for maximum use of a dust collection system, with a blastgate installed at each branch to control the air flow to the machine in use. BUT, do not invest in the plastic version, go with the metal blastgate.

If someone can explain to me what the tapered design of the inlet and outlets are for, I'll upgrade the review to 5 stars minus 2 for the overbloated price. I can't imagine what the design of a taper is for. The Y-Connectors and Splices do not have a taper. Why do the blastgates do?The problem is that the natural springness of the hose keeps it coming off the tapered outlets just as you're trying to tighten the clamps. This is frustrating to just a wee degree since the problem shouldn't exist at all. In addition, the price is just a tad expensive for a piece of plastic.Look elsewhere if you can find a better design, or a better price. Otherwise, once you have them on, they work as expected.

I would not buy these. They jam with dust. These do not come apart for cleanout. These will only work in a dust free shop. (A shop that is not used.) I recommend the metal gate at the same price. The metal gate is sturdy and solid.
