The 300P is VIAIR's entry-level overlanding portable, rated for tires up to 33 inches. 2.3 CFM at a 150 PSI cap with a 35-minute duty cycle. Same kit format as the 400P and 440P (battery clamps, 25-foot hose, soft carry bag) at a lower price point. Suitable for stock-tire SUVs and lighter rigs where the bigger 400P would be overkill.
