This compressor can inflate a 35-inch tire from 0 to 30 PSI in less than 5 or 6 minutes, according to its manufacturer. It comes with a permanent magnetic motor and the 33% duty cycle at 100 PSI ensures that the compressor can handle prolonged use without overheating and it produces 2.30 CFM at 0 PSI.

The VIAIR 400P runs on 12 volts and has a maximum amp draw of 30 amps and according to its manufacturer, the noise level of the compressor is 74 dB. It comes with a 25 ft air hose and an 8 ft power cord and features a thermal overload protector to protect the motor from overheating.

Additionally, the VIAIR 400P has an ingress protection rating of IP54, which means that it is resistant to dust and water.

Note: (Air hose that comes with this kit may become brittle from prolonged exposure to UV/sunlight so when not in use store it away. The engine must be running during use.

To check tire pressure, simply turn off the compressor to stop inflation and check the pressure on the air pressure gauge.)

Which One Should You Choose?

Both the VIAIR 300P and 400P are great air compressors that offer unique features and benefits. If you're looking for a compact and lightweight compressor that is suitable for both home and professional use, the VIAIR 300P is a great option (keep in mind that this model can inflate tires up to 33-inch).

On the other hand, if you need a more powerful and versatile compressor that can handle heavy-duty applications, the VIAIR 400P is the way to go (this unit can inflate a 35-inch tire).

Ultimately, the choice between the two will depend on your specific needs and requirements.
