Duty cycle for this compressor

Hi. My compressor is 2.5hp, belt drive, 50 litre, 13cfm and I have recently purchased a LVLP spray gun. What I've noticed is that when I adjust the on-gun regulator to the middle of the specified input range and start spraying, the air in the cylinder is quickly exhausted and then the motor kicks in. It seems that if I keep spraying continuously the air required by the gun is almost exactly equal to the air provided by the compressor, because the needle on the cylinder gauge seems to stay still (well, actually it goes up very, very slowly). Now my question is will it harm this compressor to be running it continuosly while spraying, or does it need to be rested. There is no mention of duty cycle in the so-called manual.

I have attached a photo in case its meaningful to anyone.

cheers

Looks like your going to stay with spraying.. And if that's the case, Buy another compressor the same
and hook them together , air and electric , and your problem's will be solved

Thanks for the response, but I dont have a problem - I'm just trying to work out whether I will do harm to the compressor running it continuosly - on the rare ocassion when I might do so.

Arron - shouldn't be a problem.
Mine is a 2hp running a 15CFM with a 65 litre tank, and
sometimes I can run the motor continuously for 30+ minutes...
(Air chisels can do that)
Spraying and stapling use a lot less air....
