Guys I need your help. I have a 70 gal. 2 HP Heavy Duty High Flow High Capacity Dust Collector from harbor freight and I’m trying to find a remote switch for my unit. It is a 20amp, 120v system. I can only find remote switches for 110v and 220v and most of them are for a 1-1/2hp system.

Can you guys tell me where I can get the correct remote switch for this unit. Thanks.

How about something like this contactor?

It uses a 24VAC low-current control voltage that would be provided by a small transformer. That would be wire to control switches or circuit.

I’ll be interested in seeing what works for others in response to this thread. I’ve read the specs on the PSI and the iVac, and both say 1.5hp motors. Although the reviews seem to indicate they both function fine on the HF DC. There is a lot of debate as to the true hp of the HF motor, whether it is 1.5 actual or 2 peak hp. I have not checked the amperage draw on my HF motor as of yet, but there are some posts on the internet that have shown it is under 15a startup and running way below that. Even with upgraded impellers, it doesn’t seem to draw close to 20a.

Reviews on Amazon of the PSI and iVac remotes are mixed.

Is the voltage you are concerned with? All your circuits are 120 and/or 240. They often list 110 or 220 as they indicate that they can tolerate some voltage drop off due to resistance. Any single pole 20amp remote should work. The PSI lists its single pole relay as 110v, why I don’t know, but what is coming into your house is two 120s. It is rated at 20amps. I assume they indicate 110 as a reference that it will still function if your circuit has some voltage loss, but every outlet they are plugged in to is 120v as there is no such thing as a 110v in your home.

I have that dc and have used a couple of different 110v outdoor rated remotes, review here. The 1st one quit after 1-1/2 yrs but not due to electrical load, just low quality. The 2nd is stlii working 3-1/2 yrs later, but the off button is getting finicky. These things are cheap $15.

If you get a contactor (something like wingless linked), you can make your own and have a long-lived unit. I would get one with a line voltage (12V) coil) then the contactor is switched on/off with a cheap remote made for lamp switch. That, in turn, powers the coil and turns on the collector. The beuaty of this is that if the remote fails (and it will) you simply switch in another, this is a plug/play operation…and they (the lamp remotes) can be had for as little as $10. I have such a setup on my DC (mines 240) and another I use for my HVLP turbine, which has a fairly high amp draw.

J, Have a quick squiz at my Dust extraction made easy(er) with remote control. The voltage is governed by the remote switch which should be rated at your power outlet… Just ensure that the remote controlled power points is/are rated at a minimum of 2400 watts (or greater than whatever your dusty is).

The mag-switch replacement switch was a standard light switch ($5Aus) and the remote power points was $28Aus for 3, so for about $15Aus you could remote control your unit… Now in your Yankee The Donald dollars,

it should be cheaper. If the HF dusty doesn’t have a mag switch and just a “normal” on/off switch, you can save $5Aus.

Now I don’t want to get into a political debate by the politiically correct Inquisitors, but I don’t consider a “safety switch” (mag switch) on a dusty a health hazzard.

PS. You’d have to swap out the mag-switch with any other 3rd party product… At least this way you can keep the remote in your pocket (or hang around your neck) and also use it to control the power to the shop-vac.

Ivac Pro Switch 115V-20a model is available. I have the 220V version and it works well.

Jas’, 70 gal is hard to keep track off (1 missus is bad enuf), unless it has a peek-a-boo, check out this blog Super Dust Deputy and HF Dust Collector Upgrade by chad... I did,... and immediately upgraded my collector!

I have that dust collector and I use the “LR110-3 110-Volt Long Ranger Dust Collector Switch.” Used it for several years without issue. Tried a couple cheap 110 switches that couldn’t handle it, I’m a threat to squeeze a buck. Should of just bought this one first. You may have better luck than I with cheap ones, it has been a while. I put a Thien baffle on a 55 gallon drum for my separator and been very satisfied with the collector as well. Best of luck to you.
