Performance capabilities of VIAIR 88p air compressor

Inflation Speed

  • Can inflate a 33 inch tire from 0 to 30 PSI in under 5 minutes.
  • Fills a 225/60/18 tire from 20 to 30 PSI in just 50 seconds.
  • The quick inflation times make it ideal for topping off tire pressure before hitting the trails.

Air Delivery

  • Provides 0.6 CFM free flow delivery at 0 PSI.
  • Maintains 40% of max flow even at higher pressures. 
  • Flow rate allows rapid filling of multiple tires without excessive heat buildup.

Maximum Pressure

  • Reaches peak operating pressure of 150 PSI.
  • Easily achieves needed pressure for larger truck and SUV tires.
  • Shut-off valve engages automatically at 150 PSI to prevent over-inflation damage.

Duty Cycle

  • 10% duty cycle (6 minutes on, 54 off) protects motor from overheating. 
  • Thermal protector shutoff provides additional overheat protection.
  • Can operate continuously for quick inflation of two tires before resting.

High-Amp Motor

Modifying the VIAIR 88p air compressor

Digital Pressure Gauge

  • Add a built-in digital pressure gauge that displays real-time PSI during inflation. This allows for more precise tire pressure monitoring.

Upgraded Motor

  • Replace the stock motor with a higher output max amperage motor that improves airflow to 60 CFM at 0 PSI. This significantly reduces tire inflation times.

Longer Duty Cycle

  • Modify the duty cycle to 20% (12 minutes on, 48 minutes off) to allow for longer continuous runtime before overheating.

Presta Valve Adapter

  • Include a screw-on Presta valve adapter to allow inflation of items with Presta valves like bicycle tires.

20 ft Air Hose

Protective Housing 

  • Add a molded plastic protective housing with an integrated carry handle for improved portability and ruggedness. Protects components from dirt, debris and drops.

Lithium Battery Pack

  • Bundle with a lightweight removable 18V lithium ion battery pack to allow cordless operation away from vehicle power. Can be recharged via a solar panel or wall outlet.

Digital Controls

  • Incorporate digital controls like an OLED screen and button interface to access saved pressure presets, toggle battery/vehicle power, turn on the flashlight, and display error codes.

With these upgrades, the modified VIAIR 88p becomes a highly versatile portable air compressor suitable for larger truck tires as well as modes of transportation like motorcycles and bicycles. The battery power option improves off-grid use while the digital enhancements streamline operation.

How to properly store the VIAIR 88p air compressor

Storage Location

  • Store the compressor in a clean, dry location protected from extreme temperatures. The ideal temperature range is 50-90°F.
  • Avoid storing it in humid, wet, or damp areas which could lead to internal corrosion.
  • Keep it out of direct sunlight and away from heat sources. Excessive heat can damage electronic components.


  • Store the compressor in its included carry bag or a protective case to keep out dirt, dust, and debris.
  • If the compressor won’t be used for over a month, cover the air filter inlet to prevent dust buildup internally.


  • Place the compressor on a flat, level surface rather than directly on the floor to avoid moisture damage.
  • Do not stack heavy objects on top of the compressor during storage.
  • Avoid storing the compressor at an angle or upside down. Oil could leak into airlines.

Power Cord

  • Wrap up the power cord neatly without tight bends or kinks which could stress the wiring.
  • Inspect the cord periodically for cracks or damage which could cause electrical issues.

Air Hose

  • Coil up the air hose loosely to prevent kinks. Tight bends can cause cracks over time. 
  • Make sure all moisture is drained from the hose before storage to avoid internal corrosion.


The VIAIR 88p air compressor packs some serious inflation capability in a compact and portable design. With the power to inflate up to 33 inch tires in less than a minute, this sturdy compressor is a must-have for truck and SUV owners who need to air up on the trail or in off-road conditions.

Its optimized features like the LED power indicator, 12 foot air hose, and direct battery clamps make operation straightforward even in remote locations. While the 10% duty cycle necessitates allowing breaks during prolonged use, this is a worthwhile tradeoff for the inflator’s ruggedness and reliability.

For anyone who needs quick access to compressed air for larger tires and wheels, the VIAIR 88p is one of the best portable compressors available. Its combination of performance, durability, and portability earns it a solid recommendation for off-road enthusiasts or anyone who values being prepared with tire inflation capabilities while on the go.
