4" blast gates.

1218 Views 10 Replies 6 Participants Last post by  MT Stringer
I have a 4" Y coming out of my dust collector with one of the outlets blocked off with a cap. I am thinking about running a permanent hose to my table saw. I am not sure but does a lot of air get by the blast gate when it is shut off?

a quality gate leaks very very little to virtually nothing...

Thats pretty much my setup.... a 10' dedicated line to the TS off of one side of the Y and a blast gate on the other...works well enough that I don't worry about..
A quality gate is not made out of plastic.... my metal one works fine the plastic one, not so much.
Double check your "Y". I think my Harbor Freight machine has a 5 inch inlet that the "Y" connects to. If I remove it, I would need and adapter to connect a 4 inch hose.

You may have the same setup.

Hope this helps.

My 2hp Shop Fox DC has a 6" inlet with a plastic Y to 4". I removed that and used a 6" smooth pipe system as far as I could with some 6x4 metal Y's along the way. At each junction is a (metal) blast gate. After about 25' I tapered to 4" metal. There is a minimal amount of flex hose for each machine (7 total). Unit is located outside, wired for 240v and use Long Ranger with 4 remotes. Joints are sealed with the metallic AC tape (there are 2 sheet metal screws in the whole run). Relatively small shop and it works well.
Since blast gates is part of the OP, my experience with the plastic ones is they are not self clearing. That's a real bummer because dust will collect in the track and the slide will not close properly.

The metal ones I have are self cleaning and they work well. They have a knob so you can lock the slide open, closed, or anywhere in between.
