Came across what looks like a dual motor/dual pump compressor. Seller says it is a Dayton, but doesn't have any further info on it and I cannot seem to find one like it anywhere. A few pics below show the tank and dual setup. I've read where they use dual motor/pumps to generate 2x the cfm with single-phase motors. Has anyone seen a setup like the one in the pictures before or happen to have an idea of a model number, any info appreciated.

I've seen dental setups like that.

Used where noise is an issue. Those are oiless compressors. Low volume high storage. Often set up as progressive so only one is in use most of the time.

With 8 cylinders I wouldn't mark that off as low volume. I would bet that the motors are spinning under 1800rpm vs. 3600rpm though for less noise.

I would not agree with that, just due to the size of those tiny cylinders. That's either a dental office unit or one for pneumatic HVAC system controls. Probably turns off at 80psi.

I would need to know the bore and stroke of the cylinders before qualifying them as "tiny" add to that the compressor speed and you'd have your air output.

These look like Gast oilless compressors. Good quality and not cheap. There is no free lunch though. If it makes lots of air it takes lots of power, no two ways about it. 4cfm per hp, that pretty much an iron law. Anyone claiming much more than that is lying.

I agree with the 4cfm/hp @90psi. Without the pressure qualifier then the 4 cfm is just a number. My window fan will pass a huge amount of air but at virtually no pressure. The devil is in the details.

no neat sig line
Similar compressor?

I think this, time two.
Not overly loud, Could probably bring it down quite a bit with some heftier intake filters.
You would have to check which model this is, as some are only rated to 50psi. There's one on Ebay now for $1250 for the bare pump and motor. Even the higher rated ones are only good to 100psi.
Um, yeah.....that unit above was not cheap.....

Considering the mismatched pump/tank colors, and the hokey looking way the motors are bolted to the isolate plate - I think it's something someone cobbled together. Further reinforced by the fact that half the pump heads do not appear to be connected to anything.
Also it's using push-on "Insta Grip" type hoses and fittings one of the compressor discharges. Pretty sketchy.
