This afternoon (Friday, 28 August

"This afternoon (Friday, 28 August 2026), I tried out my new Viair 450P RVS portable air compressor. I was impressed. The 450P was amazingly quiet. The air pressure gauge was accurate and easy to read. I used the screw-on, 90-degree fitting for the tire valve stems, and it worked great. All four of my RV tires (ST215/75R17. 5) had approximately 110 psi in them when I started, and the 450P had no trouble quickly kicking them up to the required 123 psi. No hesitation, no hiccups. Very pleased. It’s a keeper! Thank you."

Great quality inflator but gauge…less than accura.

"Very good build quality. Fairly quiet. Only negative found is the air gauge in the gun is inaccurate showing 5-7 lbs lower than actual pressure. Contacted Viair about that issue and they, without hesitation shipped a new gauge which I haven’t installed yet to see if the original was faulty."

This compressor is great!! The

"This compressor is great!! The tires on my RV require 110psi and my truck 80psi. This gets them topped off without effort. I love that it's quiet and easy to use. This is a must have it you travel with an RV!! Highly recommend the Viair. I tried a similar product before purchasing the Viair. I used it one time because it claimed to have the same capability of the viair and was less money. It did not!! I used it one time and returned it.dont make my mistake purchase quality you will be able to depend on. Viair won't let you down."
