Brand and Voltage
The first similarity between the Viair 400P and the Smittybilt 2781 is their voltage – both run on 12 volts. The second similarity is that they are both produced by reputable brands: Viair and Smittybilt.
Recommended Uses
While the Viair 400P is recommended for tire inflation, the Smittybilt 2781 has multiple recommended uses including drilling, air brushing, spraying, and nailing. Keep in mind that both of these compressors can still be used for a variety of purposes.
Power Source
The next difference between these two compressors is their power source. The Viair 400P is electric-powered while the Smittybilt 2781 is corded electric. This means that the Smittybilt 2781 needs to be plugged into an electrical outlet, while the Viair 400P can be powered through your vehicle’s battery.
Noise Level
Another factor to consider is the noise level of each compressor. The Viair 400P produces a noise level of 74 dB, while the Smittybilt 2781 produces a slightly lower noise level of 70 dB. This means that the Smittybilt 2781 is slightly quieter, but both compressors are still relatively loud.
Airflow
One of the most important factors to consider when comparing air compressors is their airflow. The Viair 400P has a free flow rate of 2.3 CFM at 0 PSI, while the Smittybilt 2781 has a maximum airflow of 72 liters per minute. This means that the Smittybilt 2781 has a higher airflow rate and can fill tires and equipment more quickly.
Pressure and Duty Cycle
When it comes to maximum pressure, the Viair 400P has a working pressure of 150 PSI, while the Smittybilt 2781 has a slightly lower maximum pressure of 140 PSI. However, the Smittybilt 2781 has a longer duty cycle of 40 minutes at 40 PSI and 75 degrees Fahrenheit, compared to the Viair 400P’s duty cycle of 33%.
Additional Features
Both compressors come with their own set of additional features. The Viair 400P comes with heavy-duty dual battery clamps with a 40-amp inline fuse, a deluxe carry bag, and an anti-vibration tray. However, the air hose that comes with the Viair 400P may become brittle from prolonged exposure to UV/sunlight. On the other hand, the Smittybilt 2781 comes with an integrated easy to read 150 PSI pressure gauge and a storage bag.
Conclusion
Finally, both the Viair 400P and the Smittybilt 2781 are high-quality portable air compressors that are capable of handling a variety of tasks. However, there are some key differences between the two that could make one a better choice for you over the other.
If you need a compressor that can fill tires and equipment quickly, the Smittybilt 2781 may be the better option with its higher airflow rate.
However, if you need a compressor that can be powered through your vehicle’s battery, the Viair 400P is the better choice. Ultimately, the decision comes down to your specific needs and preferences.
