Why El Cheapo compressors are no bargain

Jump to latest Follow Reply
I like my CS3. I only fill guns with it. I like the fact that I can reload mags while it's doing it's thing. I like to have enough mags to match shot count with full fill. If you don't trust the auto stop, don't use it. Just set it high and watch the gauges like any other compressor.
I made a bracket and mounted the power supply to the side of the outside case. I left a space between the PS and the case for airflow... maybe 3/8 inch.

I have the 120v version running on a dedicated 20 amp circuit with no problems.

Mine won't play on 20a for the lra but im not sure we have the same compressor. Mines a 4 cylinder big boy. I also don't know how fresh the breaker is on my 20a in terms of cylces it's seen on/off. My 5.5kva genset won't start it either 😅. Soooo I did some eletlctrician work and ran a big circuit to the garage.

We don’t, I have the twin.

I think they were a little generous with the data plates on current draw. They didn't list locked rotor draw, i suspect the 2200w rating on mine is unloaded motor draw too. I may put a 3 phase motor on there and use a 240v vfd to soft start it or do some creative load based programming.

Synthetic Diester Compressor Oils for Sale

petroleumservicecompany.com petroleumservicecompany.com
Synthetic Diester Compressor Oils are lubricants typically intended for heavy-duty, reciprocating air compressors but are not recommended for air compressors used in breathing air applications.

It's expensive but the breathing air oils are designed around our use envelope so i recommend the good stuff personally. As did the friend who owned an hpa company.

still can't find how it is legit for "dive " compressors ? the word Dive implies it is somehow made for breathable air use ? I assume it is fine for our PCP use.

I didn't buy that brand. Ignore the branding..... Buy breathing air compressor oil. Mine was 100 bucks for a gallon. When you blow down the compressor you're breathing the aerosolized nonsense that's in it unless you wear a respirator. Never hurts to be safe.

I'm not going to vouche for off list oils. It was going around long ago to use hydraulic oil in the Yong hengs and I don't agree with that either after doing it. Too many risks.

You would need a rotary phase converter.

I disagree. I run 3ph off "split phase" 240 already for my turret milling machine with a vfd. Old rotary/ motor based phase converters and cap banks are the old school way tho and they do indeed work but if I had to go that far id just buy a cap start 240v for this compressor or i/c power it for field use. That's one of the large reasons I got that compressor, it's vbelt drive so i have options.

For the benefit of the readers vfd =variable frequency drive. The reason for use being is 3 phase motors cost a little less and are easily reversible and more efficient. My interest in these started with a video I saw about shop compressors and being able to signal the vfd via load pulses to change rpm if desired. I also didn't want to pay for all the conduit and copper to run 3 phase to my mini machine shop area to run my kill 😁. If i do this I will video a little info clip.

Yeah, that gets expensive unless you have a spare motor laying around and build your own. Never tried using a VFD as a phase converter and statics are not really made for high load applications.
