Viair 70p vs. 85p: Which One to Choose?

Air compressors have become an indispensable tool for vehicle owners and drivers who love off-roading and camping in the wilderness. When it comes to choosing a reliable and high-performing air compressor, Viair is a brand that comes to mind. Among the many models available, two of the most popular are the Viair 70p and the 85p. Both of these portable compressors have their own unique features and capabilities.

In this post, we will compare and contrast the Viair 70p vs. 85p to help you decide which one is the right choice for your needs.


The primary difference between these two compressors is their performance. The Viair 70p has a maximum working pressure of 100 PSI while the 85p has a maximum pressure of 60 PSI. This means that the 70p can inflate tires that require a higher pressure than the 85p. If you own larger vehicles, such as trucks or SUVs, the 70p is the better option. On the other hand, the 85p is ideal for inflating tires of small to medium-sized vehicles including sedans and vans.


The Viair 70p is an incredibly powerful unit that runs on 12 volts, drawing 15 amps. This means that it only takes the compressor about two minutes to inflate a tire from 0 to 35 PSI. On the other hand, the 85p runs on 12 volts, drawing 14.5 amps, which inflates a tire of a small to medium-sized vehicle in approximately 2.5 minutes. While both compressors pack enough punch for their respective limits, the 70p is more suitable for high-performance and heavy-duty applications.


Another critical factor to keep in mind while choosing between the two compressors from Viair is their size and weight. The 70p is incredibly compact and lightweight, weighing only 5.2 pounds and measuring 6.8 x 3.8 x 5.8 inches. This makes it perfect for camping and off-roading trips. On the other hand, the 85p is relatively larger and heavier, weighing about 5.27 pounds and measuring 9.1 x 3.1 x 5.6 inches. Despite being larger and heavier than the 70p, the 85p is still portable and easy to carry around.


Apart from their differences in size, power, and performance, both compressors come with their unique set of features. The 70p includes a built-in LED work light, a 15-foot power cord, 4-foot air hose, and a built-in pressure gauge that allows you to monitor the tire pressure accurately. Meanwhile, the 85p comes with a deluxe carry bag, a 12-foot power cord, 3-foot air hose, and an automatic shut off feature that stops the compressor when your tire reaches your desired pressure.


Finally, the price is a crucial factor in deciding which compressor to buy. The 70p is a relatively affordable option and is priced at around $40-50. On the other hand, the 85p costs slightly more, priced at around $60-70. While both compressors from Viair are excellent value for money, the 70p is a budget-friendly option for anyone who’s looking for a reliable and robust compressor that can cater to their specific needs.


Both the Viair 70p and 85p are excellent air compressors that offer great value for money. However, they differ in terms of performance, size, power, and features. If you own larger vehicles and require more pressure, the 70p is the better option. Still, if you own a small to medium-sized vehicle and prefer something more compact and lightweight, the 85p is the right choice.

Both compressors are portable, easy to operate, and come with exciting features that make them an excellent buy. Ultimately, choosing the right compressor boils down to your specific needs, budget, and preference.
