I am setting up a remote control for my 5hp compressor so the same thing would work on the DC

What you need

1. Contactor 220v 30amp, make sure it’s rated for the HP you are using. Mine was $12.00
2. You have to decide how to trigger the contactor, could be as simple as just a switch on the wall or something that comes on every time a blast gate is open. Low voltage is great for blast gates.
3. An enclosure to house the contactor.

That’s about it.

Saw on another forum where one Gent. used a cheap radio shack light controller to trigger the contactor so he had a wireless remote in his hand.

Jcoop has it. My DC also has a 5HP Leeson, and that’s how I set it up. You can get the contactor from any industrial supply, even Clearvue. The one I use is rated for 40 amps, way overkill. The switch I use is a $10 lamp remote from Menards. You could buy a several, and use as many remotes as you need…plus when they fail (and they will fail) they are cheap to replace. To enclose the contactor I used a weather tight plastic electrical box I got at big blue in the outdoor conduit section, cost about $10. I think your setup will work fine. If you go the route of the contactor you will also need a 120V power source (to power the coil) so plan for that in the wiring installation, that could be the switches that jcoop suggested.

Just a thought….Why not forgo the bag entirely and vent it into a covered container?

I like where this is going.
I too would be tempted to vent the DC straight into a hole in the lid of a 4 yard dumpster.
I have seen woodshops with this arrangement inside the workspace, so in your situation, dust for the neighbors shouldn’t be an issue.

I am planning on venting outside as well. May just dump on the ground, but I am out in the sticks where it would not be an issue.

Thanks for the input everyone. I will certainly do this and try and figure out how to utilize the contact method while using a common remote for the 5 up DC. I am certainly excited about setting up the DC.

Hi jcoop,
We are also in the boonies and I vent straight outside. But, with the “cyclone” lidded trash can before the unit, I get hardly any dust outside.
Sure saves some space though, doesn’t it.

Venting outside would be a great idea. Get all the harmful stuff out of the shop. I will mention that removing the filters and venting outside, will decrease the static pressure in your system and increase the airflow. This of course means your dc will be drawing more amperage. This may not be a problem given the size of your shop. I have a feeling that the static pressure for your ducting system will far outweigh the lack of static pressure decrease from the absence of the filter…and the motor is 5hp.

Noise issues? The neighbors may not appreciate the sound of a 5hp motor. – lol

Sawkerf, LOL, as long as I don’t have to deal with the noise…. Actually it will be in a storage shed so the noise should be reduced even for the neighbors :)

As far as getting the harmful dust out of the shop, I think it will be an evolving process over the next couple of years. Along with the greatly improved DC I will also be working at improving the dust collection hoods at each of our machines. It sure will be nice to eliminate the vast majority of all dust / chips.

Anything to start with will be a great improvement though. Currently our only DC is a 2 hp Grizzly and it is only used for the planer, shaper, drill press and drum sander. It does capture most of the large chips from those machines but several other machines in the shop have no dust collection at all such as the 3 table saws, the 2 RAS and the 2 slider miter saws.

If your furnace is in your work room, the pull from the DC can pull the furnace’s exhaust (carbon monoxide) into the work area and cause anything from headaches, nausea, fainting,.....

anyone have any pics of how they vented their DC outside? My shop is my 2 car garage and I usually work with the big door open. I can vent to the outside because a typical garage vent is right next to the dust collector.

My question is mainly what to fabricate? I can run a 6”hose right through the garage vent without having to cut a hole in the garage wall, so that’s easy. But what do I do with the dust collector? Just put a wooden circle on top of the DC with a 6” hose connection?

Pictures would be helpful here.

Grandpa ,

I looked at the link but it was for a remote switch setup.

The Clearvue Cyclones forum ( ) has a lot of info both about setting up a remote switch and about venting outside. It uses a 5hp Leeson motor as well, so the setup and wiring is similar to your DC.
