Kobalt compressor builds pressure - but no air at hose
I have a Kobalt 10 gallon compressor with digital readout. The compressor builds pressure in the tank, but no air comes out of the hose, regardless of the pressure setting. The saftey valve, which is in the same housing as the air outlet, works fine.
Hi Larry... many, many questions about this issue. I wrote a page on it.
Click Compressor Issues in the nav bar, then Compressor Troubleshooting, then "Has no air out of hose" for details.
Air hose size
Your Air Hose Artical has a lot of very good information.
But I just have a small compressor (Kobalt Model 215921, 30 gallon on wheels). The air outlet at the compressor is 1/4". And some of my tools want a 3/8" hose and others do not. So what size of hose should I use? I was thinking of just using a 3/8" hose for every thing. Would that work?
As long as your compressor has the flow capacity at the pressure you need to run the air tools you want to use, then there is no down side to upsizing the air hose line to them. You might want to look at PRESSURE DROP for more info on that.
If your Kobalt compressor doesn't have enough flow, a larger hose size will help a bit, but you may still run out of air flow and pressure, regardless.
