i have been running a Viair 280C with a 1.5 gallon tank to some cheap ebay horns for 2 years now. it is loud but does not sound very good. we installed a K5LA setup at work last week and after hearing it i had to make the switch!
i will most likely be running a K3HA. i need a new compressor and tank but dont have a ton of cash to drop. i know i need a minimum of 5 gallons to power the horn. i was looking at a 8.5 gallon tank to have a little extra. i dont care about very fast fill ups as i wont be using the horn non stop. i see everyone is running the 480C and most are happy with it. i am looking at a single 480c or maybe twin 444C compressors. i only need 150 PSI for the K3’s.
i need some info on the airlines required for these horns. i have tiny 1/4 lines and compression fittings on my current setup. they leak constantly and the tank will empty overnight. i would like to find the push lock style fittings for the 1/2" line. i am getting a SMC valve and running 1/2 DOT air line. where can i find the needed fittings to hook form the tank to the horn?
