The VIAIR 300P is a compact and lightweight portable air compressor suitable for both home and professional use. It measures 9″ L x 4.9″ W x 7.5″ H and weighs 8.70 lbs, making it incredibly portable.

The unit is made from aluminum, which makes it both durable and lightweight, and can handle a maximum working pressure of 150 PSI, and is capable of inflating tires up to 33-inch.

Its 2.3 CFM capacity ensures efficient inflation and it has a 12-volt corded electric source and 33% duty cycle @ 100 PSI allowing for longer use.

The compressor comes with a 25-foot air hose along with an 8-foot power cord and according to its manufacturer, this unit has a sound level of 73 dB. The compressor also comes with a permanent magnetic motor and the aluminum sand tray with vibration isolators helps to reduce noise as well as vibration during use.

It also features dual battery clamps that make it easy to connect to a car battery for power. This 300p model is also equipped with safety features including a thermal overload protector for protection against overheating along with a 40-amp inline fuse holder.

Note: (Engine must be running during use and the air hose may become brittle from prolonged exposure to UV/sunlight so store it away when not in use.)

VIAIR 400P: Powerful and Versatile

Features List:

• Dimensions: 10.87″L x 5.83″W x 7.48″H
• Weight: 10.40 lbs
• Max Working Pressure: 150 PSI
• Material: Aluminum
• Max. Duty Cycle: 33% @ 100 PSI
• Motor Type: Permanent Magnetic Motor
• CFM @ 0 PSI: 2.30
• Noise Level: 74 dB
• Voltage: 12 Volts
• Power Source: Electric-powered
• Max. Amp Draw: 30 Amps
• Air Hose Length: 25 ft
• Power Cord Length: 8 ft
• Thermal Overload Protector: Yes
• 5-in-1 Inflator/Deflator Air Hose With 100 PSI Gauge
• I-Beam Sand Tray
• 40-Amp Inline Fuse Holder
• Dual Battery Clamps: Yes
• Ingress Protection Rating: IP54

The VIAIR 400P is a more powerful and versatile portable air compressor that is suitable for heavy-duty applications.

It measures 10.87" L x 5.83" W x 7.48" H and weighs 10.40 lbs, making it still portable as well as easy to carry around. Like the VIAIR 300P, it has an aluminum construction and it can handle a maximum working pressure of 150 PSI however, it can maintain this pressure for up to 15 continuous minutes at a time, with a 30-minute gap for cooling.

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.

The 5-in-1 inflator/deflator air hose with a 100 PSI gauge allows for easy inflation and deflation. The I-beam sand tray for stability, 40-amp inline fuse holder, and dual battery clamps add to the convenience and versatility of this compressor.

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.

Consider your usage frequency, the type of tasks you need to accomplish and your budget to make an informed decision, and if you find this article helpful then share it with others and have a nice day.
