Viair or Smittybilt Compressor?

Now that you are aware of the products’ main features, in this part of the review, we are going to give you a better comparison between Viair and Smittybilt.

Amount of Air Pressure

The measurement of a compressor’s maximum air pressure is in PSI or pounds per square inch.

The machines from both brands share the same amount at 150 PSI, which means all four can compress a large volume of air in each of its tanks.

Amount of Airflow

Cubic feet per minute or CFM is the unit used to measure a compressor’s amount of airflow.

Both machines from Viair offer a CFM of 2.3, while on the other hand, Smittybilt’s 2781 has 2.54 CFM, and the 2780 model has 5.65 CFM.

Compressors with higher CFMs inflate tires faster. They can transfer more air in the same amount of time. In terms of this feature, Smittybilt is indeed more superior.

Duty Cycle

You would want an air compressor that can operate for a prolonged period. The duty cycle is the time a machine can run before it needs to stop for recharge and also, to prevent overheating.

The higher the duty cycle, the longer the compressor can run for extended periods. Viair’s products have a 33% maximum duty cycle, while Smittybilt has 60%.

Although the latter brand has a higher duty cycle, this also means that it needs more time to recover before you get to use it again.
