I have read all of the Lumberjock comments on remote controls for the Harbor Freight dust collector, and none seem to address this problem. The HF collector is 2hp and draws 20amps. The $10 remotes are intended of far less amperage and burn out quickly. I’ve burnt out three. The WoodRiver control that Woodcraft sells is meant for only 1 1/2hp motors. Granted, the HP probably draws less than the advertised 20amps, but I’m reluctant to buys something that states it’s for less horse power. Sooo, my question is: Is there a modest priced remote control out there that will work for an advertised 2hp/20a motor? Thank you. —- Ned

The key words here are, “modestly priced”.
Short reply, No.

To change the internal component that does the switching for one with more capacity would probably only cost $30. Bear in mind that if you had to purchase all the components of one of those $10 remotes it would probably set you back $60. But, that would be something that would have to be done by a person with a good knowledge of electronic controls and access to those specialized components.

The rube Goldberg approach would be to use the $10 remote to switch a relay or contactor with the capacity to start the motor. That would be easily done for about $50 with a solid state relay having a 25Amp capacity. Readily available from places like Grainger, McMaster Carr, or even Radio Shack. The SSR will require a heat sink to operate at this power level but you can make your own from a piece of aluminum.

The PSI is rated for 20A.

If you’ve read all the posts re remotes for the HF DC, then you’ve seen mine where I said that my DC pulls around 15-19 amps at startup and 14 or less while running. It’s vented directly outside, which may make a difference.
My remote system is for outdoor lighting. It’s capable of controlling 4 outlets. I found it in HD’s, nursery dept. It’s about 4 years old and works every day.

I have the remote rated for 1.5HP. It works fine with my HF DC.

Actually, I just built one of those relay setups for my sprayer turbine, and did it for less than $25. The relay itself was about $10, the box to hold it about $6, and the powercord and other odds and ends another $10 or so, then you still need the remote. That said, the HF motor isn’t 2 HP and almost certainly draws less amps than that. You can get 15 amp remotes off e-bay for $15, and one of those may well serve you better than the those that are rated at 10-13 amps. I bought one of these to use in place of the relay setup I mentioned above. That DC motor is closer to 1.5HP or so, and probably actually draws in the 10-12 amp range, but you could always measure to be sure.

When switch on my 2 HP, HF DC went out, drove myself nuts trying to find a new one here in town. Yes was hung up on HP rating and amp draw. So ordered one from HF, shipping cost more than the switch. I could have used a toggle switch available locally!

While do not know if my DC actually draws 20 amps, do not think that motor actually 2 HP.

Learned about using xmas light remote for my DC over at woodnet.com many years ago. Bought one from Lowes and could turn my DC on from outside the shop with doors closed. That remote worked well for more than couple years until remote died.

Now use a $20 foot switch to operate my DC.

If cannot find a remote switch to meet your needs try a foot switch!

I have the PSI unit Rick posted and it will work well with anything that can plug into a standard 120V outlet. It’s a pretty beefy unit, with high quality construction. When I upgraded to a 220v cyclone, I repurposed the 120v remote to use with my Fuji HVLP.

I have a few cheapie remotes that we use with Christmas lights, my shed lights, etc… They do work, but make me a tad nervous thinking of running them with a heavy duty load. They would probably be fine, but the thought of a small fire in an area with dust and chips bothers me and they don’t have any UL-type ratings on them.

I think I would also unplug a cheapie if I wasn’t in the shop, as we’ve had our lights come on randomly a few times. I’d hate to come back to a running DC after a weekend or vacation.

I have been using a christmas light remote for several years with no problems. Purchased at HD.

Try a remote powered contractor. The remote would activate the contractor, which would activate the collector. Even low voltage could be used to for the control circuit.

I went a different route this time. I used waste gates with a relay on each that turns on the DC.

System works great, and there’s no remote to keep track of.

Thanks for all of the replies to my inquiry about a low cost remote control switch for a HF, 2hp, 20a dust collector.

I can’t find one that will work with 20 amps. Granted the HF collector isn’t likely pulling 20a, but I’ve burnt up three cheap “Christmas tree remotes” already. So I give up, and I’m gong to simply put together a switched outlet and a wall switch in a utility box and plug the DC into that. I’ll put the outlet and switch in a utility box and put the box on the side of the saw, and be done with it. Thanks again. —- Ned
