When it comes to choosing a portable air compressor, two models that often stand out are the Viair 70P and the Viair 85P. Both are powerful and compact, but they have distinct features that cater to different needs. This article will provide a detailed comparison between the Viair 70P and 85P, helping you make an informed decision.
Understanding Viair 70P and 85P
The Viair 70P and 85P are both part of Viair's popular portable series, designed for inflating tires, sports equipment, and other inflatables. They are known for their durability, efficiency, and user-friendly design.
Viair 70P
The Viair 70P is a versatile and compact compressor, ideal for occasional use and light-duty tasks. It's equipped with a 12-volt DC power supply, making it perfect for use in vehicles. With a maximum pressure of 100 PSI, it can inflate tires, sports balls, and air mattresses with ease.

Viair 85P
The Viair 85P, on the other hand, is a heavy-duty compressor designed for frequent and demanding use. It also operates on a 12-volt DC power supply but offers a higher maximum pressure of 120 PSI. This makes it suitable for inflating larger tires, such as those on trucks and SUVs, as well as high-pressure inflatables like kayaks and paddleboards.
Key Differences: Viair 70P vs 85P
- Maximum Pressure: The Viair 85P can reach a maximum pressure of 120 PSI, while the Viair 70P tops out at 100 PSI.
- Inflation Time: Due to its higher pressure capability, the Viair 85P may take longer to inflate tires compared to the Viair 70P.
- Duty Cycle: The Viair 85P has a longer duty cycle (20% vs 15%), meaning it can operate continuously for a longer period before needing a break.
- Noise Level: The Viair 85P is slightly noisier due to its more powerful motor.
Similarities: Viair 70P and 85P
Despite their differences, the Viair 70P and 85P share several similarities:
- Both compressors come with a carrying case for easy transportation.
- They both feature an automatic shut-off function that turns off the compressor when the desired pressure is reached.
- Both models are backed by Viair's 1-year warranty.
Which One to Choose?
The choice between the Viair 70P and 85P depends on your specific needs:

- If you're looking for a compressor for occasional use, such as inflating tires on your car or sports equipment, the Viair 70P is an excellent choice due to its compact size, quick inflation time, and lower noise level.
- For frequent and heavy-duty use, such as inflating large tires or high-pressure inflatables, the Viair 85P is the better option. Its higher maximum pressure and longer duty cycle make it a more robust and durable choice.
In the end, both the Viair 70P and 85P are high-quality compressors that offer excellent value for their price. The key is to choose the one that best fits your specific needs and usage frequency.
