I did some phone work at a local business that does national sales of LED, wiring, solenoids, light bars for police cars and ambulances, and other industrial electrical control stuff. We talked about woodworking as a hobby and he showed me his 15’x15’ wood working shop in his warehouse for some of his business ventures relating to wood projects. Dust collection topic came up and lead to him wanting automatic blast gates. We did a quickie internet search, and he was aghast at the price tags of those systems. He said he should make his own high quality metal ones for $15-$20 a piece while being remote controlled via control panel or android app (he only has a android smart phone). I told him he should then consider going national as he would get filthy rich in 3 months if his system worked out as many wood workers with dust collection cringe at the prices of what is out there currently. He then asked what would folks pay for automatic blast gates? I told him the reason why people “wish” they could buy automatic blast gates is because they know it’s too expensive to begin with for the majority of wood workers. He asked me to find out what a good price would be and if things work out, he could sell nationally.
So… I know a guy who has the engineering, electrical, business, marketing skills to fabricate his own automatic blast gates… what would you pay for such a gate?

40-50$ easy.

I actually have some motorized duct dampers I got off some jobs I plan on converting eventually.

Hard to say for sure. I’d pay the current commercial prices for automated blast gates if I had the cash around and didn’t have anything more important to buy at the moment. The catch is that there’s always something more important at the moment. But if 6”, 5” and 4” blast gates were to drop below the $100 mark, it would catch my attention for sure and I’d bookmark it in my “near future upgrades” folder.

By automated blast gate, I refer to those that open when a machine is turned on and close when it’s turned off. I don’t have any interest in a blast gate that turns my dust collector on and off because I don’t want my 3HP collector being started and stopped every time I move to a new machine. I keep it running continuously while I’m operating the machinery and adjust blast gates as I need to.

So a control panel or phone app wouldn’t be useful for me. I’d just want to turn on my machine and start cutting.

Pretty much ditto. I have current switches that turn my D.C. On when a machine comes on but I really want to open the gate to that machine when it starts.

Depends on what market you’re going after. If you’re going after production shops I would think you would do very well at the $75 price point with something fairly robust. If you’re going after a hobbyist like me, who would love the gate to open automatically when I turn on a particular piece of equipment, I would need about a $20-$30 price point to consider it. I get the integrated control panel as a central command point, but have no clue why I would want an android app??? What I would I do with that, control the open close of the gate? I would prefer it to be automated when I turn on the machine with a 2-3 second delay when re-closing.

+1 to becikeja. However, if they were metal gates, then I’d gladly pay $40-50 each.

Put me down for a $50 price point.

If he can make them for $15 – $20 each (for 4” gates) then that would attract a ton of people who are otherwise content with manual gates. If he did offer well made, automated gates at that price he would have to quickly increase production capacity or plan on being bought out very quickly by another producer that didn’t want a comparable product on the market available for a fraction of what they’re charging.

I would be interested in 6” blast gates if they were the sub $50 range. Even then it might be a stretch as it’s more of a convenience item and I have about 10 sets to change out. A no brainer at 6” would more than likely need to be $35.

The kicker would be that some tools are 110v, 220v single phase and 220v three phase. Not sure what it would take to make all of that work together.

I have used both iVac and Grngate automated systems. The key to the fully automated systems is that they close the blast gate after each use. This is the feature that makes them so useful. You’ll never forget to close a blast gate again!

So for me to consider anything else, it would have to include that feature.

As of today, the Grngate system is running $395 for a three gate system, and about a hundred bucks for each additional gate. For what it does, and for the health benefits of properly collecting dust, I consider that a relative bargain. When we’re old and wheezing in a hospital bed somewhere, it won’t seem too expensive.

Health, Health, Health. It’s one of those things that once it’s gone, no amount of money will bring it back.

Holbs, the question is not what people are willing to pay per gate, but how many people would be willing to buy at particular price points. As an example, maybe 75% of woodworkers would buy them for $25, 50% for $35, 25% for $50, etc. Once a price-volume curve has been established, your friend can determine the point on the curve that works best for him after he accurately determines his fully loaded costs.

I would like a system that works with a magnetic switch on the DC, will turn the DC on when a machine is started, close the gate 3 seconds after the machine is turned off and will turn the DC off after 5-10 (user defined) minutes of no machine running.

I’ll pass these comments to him next time I see him (probably next week). I know nothing about automatic blast gate functionality nor do’s/dont’s so this is good info to pass along
