I just went through this .. 400c fills faster, but it is only a 33% duty cycle compressor ... 450c fills a little slower, but as a result is a 100% duty cycle compressor. I went with the 400c as I only use mine occasionally and faster fill was more important than having it be able to run all the time without burning up.

i just found out from a friend that the 450's dont last very long, even though they are 100% duty cycle. he said that the average life of them is 6 months, depending on how hard he was on em.. he has two 400's that have lasted him 2 years now. he also said the 400's actually fill up faster then the 450's, im gonna run the 400's because of this....

still dont know what the H and C mean after the part#, but o well guess its not important....

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?

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.

the 550 is 100% duty cycle, but not weatherproof. pulls around 30 amps.

the 400 is slower than the 550, but faster than the 450. The 400 is 33% duty cycle rated, and not weatherproof.

The 450 is the slower of the 3, but has a 100% duty cycle, and can withstand weather. Hope this clears everything up.

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?

My 400 is underneath my truck. It is just fine under there and is weatherproof. I believe the 550 (?) is the one that is not weatherproof since it is not a sealed unit.
