Hi all I have been searching to buy a DC but have seen that many people are modifying HF DC. I think it will work fine for me.

What’s the power requirements? Can it be directly plugged into any 20amp outlet?

Yes, it will run on a 20amp circuit.

If you are looking to do the Rikon impeller upgrade it might be a while. I haven’t seen one in stock anywhere in months.

I used the HF 2HP model for years. Worked well for me, and is still running in a friends shop.

Mine is on a 20 A circuit and I’ve never tripped the breaker. I’ve never tried to use it on a 15 A outlet.

Looks like out of stock. What other alternatives I can use other than Hf?

I have set up and run three of these (two in a shop where I worked and one in my shop). The first one I set up was a replacement (upgrade) plugged into a 15 amp power strip, the HF would consistently trip the power strip (I was using the power strip as a remote switch). I replaced the power strip with 20 amp components wired onto a bench. When connected to a 20 amp breaker I’ve never tripped the breaker on any of the three units. Also consider that the HF DC has a high start load, once running it uses much less power.

Harbor Freight’s web site specs the motor on their dust collector as being a 2HP motor. They also state an amperage requirement of 20 amps. So it makes sense that the machine would trip a 15 A powerstrip.

Theres a YouTube vid of before/after power draw and performance of the Rikon impeller upgrade on a HF DC unit. Fairly decent and the guy does a good job of measuring the before and after parameters for comparison. Link: https://www.youtube.com/watch?v=2NOZTlwHe3A&t=120s

Overall, that guy’s installation drew about 9% more power on average while increasing static pressure by 35-ish% and increasing flow by about 20%. Looked like a 20 A circuit was still good for that collection setup.

Can’t help with the “out of stock” condition for Rikon parts.

I have considered the impeller upgrade, but not acted on it. Instead, I just finished up a reconfiguration of my system with an emphasis on shorter duct runs. I reduced individual run lengths by 20-90%. I don’t have any objective measurements, but I know I’ve increased my system’s efficiency by a great deal at very little cost as I reused as much as I could. I did spend about $50 on some new sheet metal duct fittings and a couple of metal blast gates as I added one more input point into the system. I removed about 20 feet of duct from the overall system.

If a new impeller isn’t available, I think I’d concentrate on making your system as efficient as possible (duct-wise) and see if that meets your need.

I have one, and use it without any probs. Added good felted bags. I’m a happy camper.

The impeller change yields somewhat mixed results. You get more pressure and flow but the motor runs a lot hotter. My test results are here.

I’ve had one for years. The on/off switch got finicky, so I bought a remote control key fob switch for like $15.
I should’ve bought the switch much, much sooner.
It works like a charm.

Otherwise, it is a stock setup.

I suggest bypassing the dust distributor and go for a real dust collector. Clearview or Oneida

I just ran a test with the HF kill o watt meter. The DC runs at 10.25 amps, couldn’t get a reading on startup though.

For comparison the HF 4×36 belt sander ran at 2.5 amp no load and I got it up to 3.25 while sanding.

Starting current can be 3 X the running current.

Start current for the HFDC is about 67A. Running current depends upon airflow.
