I have a 5 gallon twin tank and although its a relativley small tank it
has a fast recharge time - about 15 seconds for it to go from when it
kicks on until it reaches just around 145PSI. In the manual it states
that the compressor has a 50% duty cycle. Am I understanding this
right to mean that if my compressor recharges for 15 sec then I need to
let it idle for a minimum of 15 seconds before it should be kicking on
again?

Thanks,

-Brent
