## Questions & Answers

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

**Q: Viair website shows part number for this item as 45057 and this listing show the part number as 45053. which is it?**
A: 45057 is only available through RV dealers like united RV, technorv.com or bob hurley rv.
This listing is for 45053

**Q: What is tbe difference betweet the 45053 and the 45043? Just the rv kit or the compressor its self?**
A: 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.

**Q: If i already have the 440p can i purchase the rv accessories separately?**
A: No, unfortunately the 440P has a different size attachments and it is NOT an automatic compressor.Thank you
