Dillinja666 said:what does the H and C mean on the viair 450h and 450c compressors?
also which do u reccomend the 400 or 450? pros/cons?
400 is 33% duty cycle, 450 is 100% ... the 400 will fill 5 gallons quicker than the 450, but you cant do it as much .. running air tools you might want to get the 450, just filling tires a 400 would do fine.slimm44 said:while you guys are on this topic: what would a good compressor be to add for on-board air (mostly for airing up the tires and such)? like a 400 100% duty? and would it be better to run a tank too?
Thats the first I ever heard the 400 is not weatherproof ... I thought the 400 and the 450 are almost the same thing, how could one not be weatherproof?Beyond Static said:the 400 is slower than the 550, but faster than the 450. The 400 is 33% duty cycle rated, and not weatherproof.
