The HVLP gun needs a lot more than 8 cfm of air -- but it needs it at 10 psi (or less). My gun operates at approximately 6 psi. For compressors, ignoring all the losses you have in the pressure reducer, water separator and pipes, pressure times cfm is a constant. If you have a compressor that is rated at 8 cfm @ 90 psi, then that compressor can provide an output of 80 cfm at 9 psi. (8x90 = 80x9). Just like a high pressure gun, you need to look at both pressure and volume to determine what you need for a source. In short, a small compressor is totally inadequate for a production-size HVLP gun. Fisheye is normally caused by silicone contamination. |
