The Stovebolt Site Forums The Shop Area Paint and Body Shop Is my air compressor good enough for HVLP

Hello,
I have an air compressor that is rated at 5.8 cfm with a 20 gallon tank. Is this enough to spray with?


Thanks,
brian

Brian,

It all depends on the model of the gun and what nozzle you have installed.

For example; the link below is a tech sheet for one model of Binks HVLP gun. Depending on the nozzle size, the CFM and pressure requirements vary widely. Check the spec sheet on the HVLP gun you are planning on using and that will tell you if your compressor can supply it.

For example, the gun listed in this service bulletin with a 90P nozzle would work just fine with your compressor. With any other nozzle it would struggle to keep up.

Everything depends on the gun. It will determine what size compressor you need. I have a Finishline III and it requires 13.5 CFM at 40psi at the gun. Remember your talking HVLP the key is high volume. If your just using a small touch-up HVLP gun your compressor might work for it but if your loooking to paint a whole truck I'd be looking for a much bigger compressor.
