bushwacked Posted January 14, 2020 Report Share Posted January 14, 2020 The leading contender for my garage DC setup is PVC pipe ... However, I am not 100% on what blast gates I should be looking into? I heat the metal ones could have leaking issues possibly. I dont really want to build them if I can avoid it. What is everyone else using and happy with? Quote Link to comment Share on other sites More sharing options...
Chestnut Posted January 14, 2020 Report Share Posted January 14, 2020 Lee valley self cleaning. Best blast gate for the money of the many I've tried. https://www.leevalley.com/en-us/shop/tools/workshop/dust-collection/parts-and-accessories/51506-self-cleaning-blast-gates they fit inside SDR35 pvc quite nicely.

Agreed, they are nice & nicely priced. And of course they leak, but only a miniscule amount. I seriously doubt there are totally leak proof ones, unless maybe if you spent a fortune on them. 1 Quote Link to comment Share on other sites More sharing options...
pkinneb Posted January 14, 2020 Report Share Posted January 14, 2020 I have metal pipe and blast gets never had any issues with keeping them clean or leaking, 15 years and counting. The dust collector should pull them tight when closed or am I missing something? Quote Link to comment Share on other sites More sharing options...
Chet Posted January 14, 2020 Report Share Posted January 14, 2020 I have similar gates to the ones posted above. I personally think that people that think their gate leaks don't understand that there has to be some minor flow through the end of the gate or it will clog with dust and then won't close properly.

Certainly not enough to matter at all. Quote Link to comment Share on other sites More sharing options...
Coop Posted January 14, 2020 Report Share Posted January 14, 2020 Should the gates be located to eliminate as much flex hose than convenience or a combination of both? Quote Link to comment Share on other sites More sharing options...

These as self cleaning so the debrisgets pushed out when they are closed. Otherwise yes gates need some flow leaking to work right. 14 minutes ago, Coop said: Should the gates be located to eliminate as much flex hose than convenience or a combination of both? Combination. An inconvenient blast gate will get left open don't ask me how i know . 23 minutes ago, drzaius said: When I say they leak, I mean just enough that a small amount of air can be heard hissing at the gate. Certainly not enough to matter at all. Mine seal pretty dang well. If they hiss i sure can't hear it over the collector. With hearing protection on i can't even tell if the dc is on our not let alone a hissing gate. Quote Link to comment Share on other sites More sharing options...
Coop Posted January 14, 2020 Report Share Posted January 14, 2020 Are the vertical drops to each machine away from a wall, supported only by the drops themselves and not by any other mechanical means such as unistrut or angle iron? If not, then you have to be diligent when opening and closing the gates? Quote Link to comment Share on other sites More sharing options...

Well, my collector is so quiet, being in its own little soundproof room, that I do hear the hiss of the gates when they're all closed. If I open one of them, then no, I don't hear them.

Flex hose adds drag which is not good so the shorter the better...having said that I have 20' of 6" flex hose to my J/P and never had an issue 1 Quote Link to comment Share on other sites More sharing options...
BillyJack Posted January 15, 2020 Report Share Posted January 15, 2020 All the shops I've worked at I have never seen a metal blast gate not leak. If that bothers you make your own. I did... I have to add one to another sander and a band saw this summer and I'll make those.... Quote Link to comment Share on other sites More sharing options...
Chip Sawdust Posted January 19, 2020 Report Share Posted January 19, 2020 I have cheap plastic HF gates and they have a built-in leak, a notch on the closing end of the gate. But I’ve till got decent performance; I only use my DC on one tool at a time. Quote Link to comment Share on other sites More sharing options...
