This is my fourth Viair
"This is my fourth Viair compressor. I have the 450 digital, a 450 non digital, a 400P and an EVC31 Pro. No problems with any of them. Great products that are dependable."
We’ve taken two of our top-selling RV compressors and made them smarter. The 400P EF and 450P EF Digital RV build on the proven performance of the original platforms with digital controls and preset auto-stop for easier, more accurate inflation.
Simply set your target pressure and let the compressor do the rest. The digital pressure gauge eliminates the guesswork of manual gauges, while the auto-stop function delivers consistent, repeatable results every time.
Designed for RVs and vehicle + trailer combinations, each kit includes two coiled air hoses for up to 50 ft. of total reach and a 45-degree dually attachment for easier access to inner rear wheels. Both models also feature Enhanced Flow technology, a redesigned head for improved heat dissipation, an LED work light with emergency flashing mode, and an all-new carry bag for easy deployment and storage.
Choose the 400P EF RV for faster inflation and maximum airflow, or the 450P EF RV for longer run times and demanding high-pressure applications. Both deliver proven VIAIR performance with smarter controls and the reach, accuracy, and convenience needed to keep your RV and tow vehicle ready for the road.
