POWERTEC 70108 4 Inch Blast Gate for Dust Collector, Dust Collection Fittings

Great product! I used this to put in the window of the room where I have my laser engraver. I attached it to a piece of plywood that I then placed in the window opening. Attached a standard dryer vent hose and it works great! I like that I can close the vent by sliding the little door.

They work, just a little small I take a couple wraps of tape and they work great.

That's what it claims but the catch that holds it open will eventually break. As an example mine broken just under 2 years and now when I open it if it is sitting upright it will eventually fall down to be slightly closed reducing airflow. Not a huge problem but one that cost you the star just make sure you have the slider pointed downward and it will not fall closed.

Didn’t work initially and gave them a one star rating, but contacted the seller and they made it right immediately! Mad it didn’t come in my new Lariat truck as it did in my 2022 model. But Works great now and fits nicely in my 2025 F150 Truck! Customer service was the difference! I’d recommend them without reservation!

Product works as designed no issues good product at a fair price

I used these when I built my HF dust collection system. For any DIYers or woodworkers, having good dust collection is key to keeping the shop clean. There's more expensive brands but these get the job done. I needed the 4 inch for the larger suction and they have worked great. They aren't heavy duty but so far I haven't had any issues.

Good product

I put about 8 of these on tools around my shop to connect them to a jet 1300 CFM did collector. On one of them, the plastic had split apart so the sliding gate would just fall out. I super glued it back together and it was ok. Big problem is that over the next 3-4 weeks they would no longer close all the way. I tried removing trapped dust with a tooth pick but it was too much work and not effective. You can see what happens in the picture. I took one apart so I could see exactly what was going on. Dust will get trapped and the gate won't close fully. If the small opening doesn't bother you then it's fine. With as many tools as I have connected to the system, that opening across all of them is equivalent to a fully open gate so it's not viable. I had to replace them all with gates that go both ways so they don't clog.

Excelente justo lo que necesito

My husband needed this product and he is very happy with it and it came very quickly in the post. Thank you Amazon.

Nota 10

As described. I have this 4" blast gate and a 2.5" blast gate going from my dust collect to separate hoses. Both blast gates are sturdy and work well.

ich habe gedacht es ist ein wenig stabiler gebaut .
