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
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.
