If you need a product that can provide reliable, high-pressure air, you may need a portable air compressor. Portable air compressors can be used for a wide variety of tasks, from filling a tire at home to helping with professional HVAC control systems. Viair has three very similar portable air compressors on the market right now, and each comes with a few key differences that set it apart from the others. Let’s explore the features of all three products, and see which one would be the best fit for your unique portable air compressor needs!

Viair 300P Portable Air Compressor

VIAIR 300P

The Viair 300P portable air compressor is designed to help you fill tires quickly and easily while travelling, and comes with a lightweight of 8.6 pounds for easy transport. This product delivers 150 PSI for filling tires at a maximum of 33 inches, for your added convenience with many vehicles.

This product comes with an inline pressure gauge that is a 5-in-1 deflator/inflator for added ease of use, which reads 120 PSI. This deflator/inflator allows you to check your tire pressure, air down, intermittently air down, intermittently air up, and air up, for your convenience.

This product can work continuously for 15 minutes, but requires an additional 30 minutes to cool down properly. This product utilizes a 12-volt battery, and comes with a tire inflation hose that is open-ended. This product also comes with an 8-foot power cable to give you more range while working, as well as a carry bag to help you transport the device easily.

The Viair 300P has a sand tray, which has vibration isolators incorporated inside to help reduce vibration during use. This product also comes with an inline fuse holder for your added convenience, and a kit with 3 inflation tips and a direct battery clamp set. To protect your device, this product will automatically shut off if it gets too hot.

The Viair 400P similarly comes with a 5-in-1 deflator/inflator to save you time and effort, which can intermittently air up and down, as well as air up and down regularly, and check tire pressure. This gauge reads 120 PSI for your convenience.

This product also comes with the ability to work continuously for 15 minutes, but requires 30 minutes of cool off time afterwards, like the former product. This product also features a 12-volt battery, an 8-foot power cable, carry bag, an open-ended inflator hose, and heavy-duty clamps that work directly with the battery.

The Viair 400P also comes with a sand tray, like the previous product, that reduces vibration by incorporating isolators. This product also has an inline fuse holder, as well as a 3-tip inflation kit. Like the former product, this product will also shut off if the motor detects that it is too hot.

The Viair 440P portable air compressor comes with many of the same features as the previous two products, but differs in a higher weight of 13.67 pounds. This product can refill tires at a maximum of 37 inches, to give you even more versatility with this portable air compressor. This product delivers a maximum of 150 PSI like the previous two products.

This air compressor comes with a 5-in-1 deflator/inflator for your convenience that functions the same way as the previous two products’ deflator/inflators did. The Viair 440P’s deflator/inflator also reads 120 PSI for your convenience. This product can work for 15 minutes continuously, but requires a cool down time of 30 minutes before more working.

This product also features a 12-volt battery, as well as an 8-foot power cable, a carry bag that comes with compartments for additional storage, and direct battery clamps. A sand tray that is designed to be heavy duty, with vibration isolators, accompanies this.

The Viair 440P similarly comes with a 3-tip inflation kit and an inline fuse holder. Unlike the previous two products, this product delivers 50 AMPS in its fuse, and has a higher free flow of 3 CFM at 0 PSI. Like the previous two products, the Viair 440P comes with automatic shut off to protect the motor in the event of overheating or overwork. This allows the motor to work much longer, providing product longevity.

Recommendation

If you need a product that is lightweight, can fill tires up to 33 inches, and comes with a 40 AMP fuse, and a large variety of additional features for your convenience, then the Viair 300P portable air compressor may be for you. Conversely, if you need a product that is the lightest of the three at 8.5 pounds, and delivers a similar 40 AMP fuse, and can fill tires up to 35 inches easily, then the Viair 400P portable air compressor may be a better fit for your needs.

Alternatively, if you need a product that has a heavier weight at 13.67 pounds, offers a 50 AMP fuse, has a higher free flow at 3.0 CFM, can fill tires up to 37 inches, and comes with many of the same features as the previous products, then the Viair 440P may be the best fit for your needs.
