We’ve taken two of our top-selling portable compressors and made them smarter. The 400P EF and 450P EF Digital 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. Beyond the digital upgrade, both models 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 Digital for faster inflation and maximum airflow, or the 450P EF Digital for longer run times and demanding high-pressure applications. Whichever model fits your needs, you get a smarter, quieter and more precise version of a VIAIR classic - built with the performance you trust and the added control and convenience of digital inflation.
