I am totally confused ... Is this product a 33% duty cycle or 100%? Why does it list both specsm

There are two different models.....400P-RV runs at 33% duty cycle (The 400P-RV can only run continuously at 100 psi for 20 mins before needing to cool down.) The 450P-RV has a duty cycle of 100% (The 450P-RV is a slower filling compressor, due to the lower CFM, but it can be run continuously at 100 psi for up to an hour before needing to cool down.)

Viair website shows part number for this item as 45057 and this listing show the part number as 45053. which is it?

45057 is only available through RV dealers like united RV, technorv.com or bob hurley rv. This listing is for 45053

What is tbe difference betweet the 45053 and the 45043? Just the rv kit or the compressor its self?

Zack, The compressors are essentially the same. The RV version has extra attachments that help when filling motor-home tires: a 45 degree chuck, a 90 degree chuck and an additional 30ft of air hose. Let us know if you have any other question. VIAIR Corporation

If i already have the 440p can i purchase the rv accessories separately?

No, unfortunately the 440P has a different size attachments and it is NOT an automatic compressor.Thank you
