Blast Gates

[racerbear02]

I will be installing a dust extraction system using blast gates to select the machine being extracted.

I have seen pictures of them mounted in both horizontal and vertical runs of pipework, is either any better than the other?

Also should I set them up so that the gates slide horizontally or vertically?

Thanks in advance again

I don't think it matters if they are vertical or horizontal, but for the ones you have, it's best to find a position such that crap does not clog up the slots that the gate slides in. Also I find that metal ones are far easier to operate than plastic ones and less likely to go stiff if dirt gets in beside the sliding gate.

Yet again, Thanks

As above... I usually just place them where convenient for the particular machine.... always use metal... I am actually doing a load in a workshop this week having just installed a 1150 mm wide sanding machine

To keep the pipe runs short I have had to place a blast gate up at roof level, I just use a brush shank with a cup hook on the end to open and close it.
