I have twin 380c's and think they are about the best deal for larger volume storage, decent recovery, and always workin. 8.5 gallons of 200 psi air makes a lot of noise when ya let it rip through a 1951 diesel train horn !

 

Yes sir

 

100% duty cycle is good, but I have not been able to find air usage on a set of air horns. If you have a compressor good for 100% duty cycle and it only puts out .65 cfm at full pressure, what good is it if you drain the tank in 2 seconds with a set of horns that use 5 cfm? Also when looking at a 100% duty cycle compressor, look at the amp draw. Most of them are upwards of 35 amp and I have seen a couple that use 85 amps under full load.
