What is the duty cycle of a Kobalt compressor model # 0300841?

What is the duty cycle of model # 0300841, and how large an auxiliary tank could it support? Thanks…Frank K.

……….

That species would normally be no more than 50%. “How large an auxiliary tank could it support? ” Depends on what you mean by support. It would likely fill a 120 gallon tank in a half hour, but might kill itself doing so. And most tanks aren’t cheap, so it may be a better deal to get a bigger machine.

The question is what is your intended use, says Doug from s.d.ca?

And Frank – if you are considering buying this, I’d stay away on the simple ground that the manifold is a unit casting, and apparently unavailable as a distinct part, or even as part of an assembly.

You would be able to replace it with pipe fittings, if needed, but that’s a pain.

……….

Doug, I would primarily use air tools like angle grinders, buffers, and drivers 3/8 & 1/2. Almost always only one tool at a time. I already own the machine. Just underestimated my requirements. Frank.

……….

You can forget running a buffer as it stands. Grinders are probably OK at least for smaller jobs. Ditto for the wrenches, assuming you’re mostly changing tires.

You might also consider buying an additional compressor and running them in parallel.

Good luck.
