If you’ve ever experienced a flat tire on an empty or off-road route, you’re probably aware and appreciate the importance of a reliable, heavy-duty air compressor.

Both the Viair 70P and 85P models are great choices that provide you with good value for your money.

And if you’re not sure which one you should get, continue reading to check out our Viair 70P vs. Viair 85P comparison that will help you make the decision.


It’s not surprising that both models share certain similarities that the company integrates into its units
Both of them are pretty easy to use. You simply plug the compressor into your car cigarette lighter (with a minimum power of 15 amps) while the engine is running. Then, you twist the brass chuck onto the tire and turn the compressor one.

Turning off the compressor will give you the most precise reading on the gauge.

Moreover, both of them are 12-volt portable compressors. Also, both of them come with a 3-piece inflation tip kit and a deluxe carry bag to enable you to store and transport the units easily.


Portable air compressors are available in various shapes, sizes, and colors. So how do the Viair 70P and 85P differ in those aspects?

The Viair 70P

The Viair 70P has a black and silver body and a handle on top that enables you to carry it around. Weighing 5 pounds, it’s not too heavy and can be easily maneuvered –especially with the 15-foot cord that provides you with enough length to move around.

And with a 10.5 x 6.8 x 5.8-inch footprint, the Viair 70P doesn’t occupy much space and can be stored easily.

The Viair 85P

This model also has a black and silver body, but its handle is integrated into the machine instead of being on top.

It’s quite compact and lightweight, as it has a 9.2 x 5.5 x 6.8-inch footprint and weighs only 4.3 pounds. This means that you can easily store it and carry it from one place to another.

However, its cord is only 10 feet long. It’s good enough to move around a little but doesn’t give you as much freedom as the 70P’s cord would.

Winner: The Viair 70P.

Pressures and Uses

While you can use your air compressors for various purposes such as inflating tools, balls, inflatable pools, sports equipment, and more, we’re going to focus on the main purpose: tires.

The Viair 70P

The 70P is suitable for a maximum tire size of 225/60/18. It can work at a maximum pressure of 100 PSI, and at 0 PSI, it produces 1.06 CFM free flow.

The Viair 85P

The 85P suits tires of all sizes up to 31”. Its maximum pressure is 60 PSI, while its free flow is 1.26 CFM.

Winner: Tie.

Extra Features and Accessories

While there aren’t many accessories for an air compressor apart from the basic ones, an inflation kit is pretty essential. This is because it allows you to change the head.

Other practical items would be a carrying bag and, of course, warranty.

The Viair 70P

Apart from the premium quality bag and 3-piece inflation kit, there isn’t much else to the Viair 70P.

But that doesn’t mean that it doesn’t provide you with good value for your money.

The Viair 85P

The Viair 85P comes with the same carry bag and 3-piece inflation kit but with the addition of a helpful LED work light.

Winner: The Viair 85P.

Viair 70P vs. Viair 85P: Which is Better Overall?

While both the Viair 70P and 80P are great choices, the differences make each model superior in a unique way.

Opt for the 70P if you’re looking for more practical use with lots of maneuverability. It’s also pretty efficient and provides you with ample pressure levels. However, it only suits lighter-duty tasks.

On the other hand, if you’re looking for a more compact and portable option, I’d recommend the 85P. It also has a helpful LED light. However, it may not provide as much pressure as the 70P.

While it may accommodate heavier-duty jobs, you should work with a 20 amp cigarette lighter source. Otherwise, you’ll get a lot of fuses blown.
