## Overview

The VIAIR 400P Portable Compressor is a 12-volt, heavy-duty inflator delivering up to 150 PSI with a 2.3 CFM airflow. Designed for rapid inflation of large tires, it features a 33% duty cycle and thermal overload protection. Equipped with a 5-in-1 inflator/deflator gauge, deluxe carry bag, and anti-vibration tray, it’s the go-to compressor for off-roaders and professionals needing reliable, portable tire inflation.

## Description

Viair 400P Portable Compressor is a larger portable compressor kit that can inflate up to a 35 inch tire from 0 to 30 PSI in less than 5 minutes by simply attaching its supplied heavy duty battery clamp power leads to the battery, attaching the lever style air chuck to a tire valve stem and turning the unit on. Air pressure can be monitored using the 5-in-1 inline inflator/deflator hose and gauge included. Always turn off the unit to take an accurate pressure reading since air flow into the tire will show an inaccurate pressure reading while the compressor is running. Used and approved of by off road enthusiasts worldwide. Let compressor cool off for about 30 minutes to allow thermal overload reset

## Questions & Answers

**Q: how long will it take to pump 4 off  265/75/16 from 15psi to 60psi**
A: My tires are 285/75R16 and it takes about 4 minutes to air up from 30 psi to 65 psi (each tire). So, about 16 minutes for all four. The run time is 20 minutes per hour, so no cool down is necessary with the 400P model.

**Q: Can it fill 5th wheel tires to 110 PSI  ST235/85R16  (G)**
A: The specifications on the manufactures website says the max working pressure of the 400P is 150 psi. Please note the 400P has an 8ft power cord and 25ft air hose. Depending were you will receive power from, you might want to consider also purchasing the 30ft extension hose. Viair part number 00030.

**Q: I have 33x12.5.15 inch General Grabber offroad tires, will this compressor work well?**
A: I also have 33x12.5 off road tires that I air down on the trail and use this compressor to air them back up. It works well and it is quick.

**Q: The 400p says both 2.3cfm and 2.54cfm while the 300p says both 2.3cfm and 2.4cfm. what is the advantage of the 400p over the 300p, if any?**
A: 400P Specifications - 12-Volt / 24-Volt- Permanent Magnetic Motor- Duty Cycle: 33% @ 100 PSI- Max. Working Pressure: 150 PSI- Max. 12V Amp Draw: 30 Amps300 P Specifications 12-Volt- Permanent Magnetic Motor- Duty Cycle: 33% @ 100 PSI- Max. Working Pressure: 150 PSI- Max. Amp Draw: 30 AmpsBasically 400P fills faster than 300P.
