I would be quite surprised if that compressor could produce a true 7cfm of "free air". Most 2HP rated compressors I have seen are closer to 3-4cfm.

I have never used latex paint, but I tried to run a small touch up gravity gun with a 2HP 3cfm compressor, with the gun throttled back as far as I could on all 3 adjustments, and the compressor just kept it going, but was running flat out with no break, so it got hot and started leaking oil.

I then got a 7.5cfm 2.75HP v-twin compressor (AUD$315) and it copes quite easily with the gun on the same settings and shuts down from time to time.

I think that most small guns are rated for around 12-14cfm to be able to run fully "open".
