All air compressors are built with a duty cycle rating. This rating is typically given as a percentage of the amount of time that an air compressor can be run in a full cycle, typically one hour, that includes the compressor’s run time and rest time.

Some compressors, such as Viair air compressors are built with a thermal protection that will automatically shut them down when they reach a temperature that they can be damaged. Others may not and it is up to the operator to shut them down in the correct amount of time. The compressor must be off and cooling down for the rest of the time they were run to avoid damage.

Air Compressor Duty cycle refers to the amount of time a compressor can be operated in a given time period at 100 PSI, and a standard ambient temperature of 72° F. If you are running the air compressor in the dead of winter or on a hot summer day, the amount of cool down time will vary. With duty cycle, It's all about heat dissipation and the rates will vary depending on ambient temperatures and operating conditions.

Duty Cycle is almost always expressed in percentage format: Compressor on time ÷ (on time + off time) = Duty Cycle %. The times to duty cycle in an hour is broken down in a chart below.

9% Duty Cycle      5 Minutes On / 55 Minutes Off or Cool-Down time
10% Duty Cycle     6 Minutes On / 54 Minutes Off or Cool-Down time
15% Duty Cycle     9 Minutes On / 51 Minutes Off or Cool-Down time
20% Duty Cycle     12 Minutes On / 48 Minutes Off or Cool-Down time
25% Duty Cycle     15 Minutes On / 45 Minutes Off or Cool-Down time
30% Duty Cycle     18 Minutes On / 42 Minutes Off or Cool-Down time
50% Duty Cycle     30 Minutes On / 30 Minutes Off or Cool-Down time
100% Duty Cycle   1 Hour Run Time or Constant Duty

If you want to break it down into 10 minute intervals - if an air compressor has a duty cycle of 50%, the air compressor will be running for 10 minutes, then it should run for a combined maximum of 5 minutes ON and 5 minutes OFF.  If the compressor is 60% duty cycle this means the compressor must be off for approximately 4 minutes of every 10 minutes.

If your air compressor is maintained and the duty cycle followed they will provide many years of reliable service.

Viair portable air compressors make sure you never get caught without air. A portable air compressor may sit in your trunk or the back of your truck most of the time and not be the coolest car or truck accessory to have, until you need air of course. Ever have low tire pressure and air is nowhere to be found? With the Viair 87P you will always have air when you need it.

The Viair 87p connects directly to your car or trucks battery and can inflate up to 31 inch tires. The portable air compressor kits includes a 120 PSI air pressure gauge, a solid brass twist on tire chuck, inflation tips and a built in LED work light with a power indicator. The power code is 10 ft. long and the air hose is 3 ft. long, so you won’t have any problems getting the air to your tires.

The Viair 87P in not only good for emergencies, but did you know you can improve your gas mileage by up to 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires. With the Viair 87P portable air compressor you can easily maintain properly inflated tires which will save money, be safer and ensure your tires last longer. The proper tire pressure for your car or truck is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.

VIAIR has introduced the new Automatic Deployment Air (ADA) Systems for the 2007-2011 and 2012 Jeep Wrangler.  VIAIR Automatic Deployment Air Systems incorporate a 12-port extruded aluminum air tank to provide a compact air locker and tire inflation station using either a 400C (Heavy Duty) or 450C (Constant Duty) compressor at its core.

The heavy duty system utilizes the 400C compressor that has a 12 volt permanent magnetic motor capable of running a duty cycle of 33% @ 100 PSI at 26 amps.  The constant duty system utilizes the 450C compressor that has a 12 volt permanent magnetic motor capable of running a duty cycle of 100% @ 100 PSI at 19 amps. 

Each ADA System comes complete with an onboard pressure switch, automatic coupler and a Digital Tire Inflation Kit. Additionally, a wiring harness is included to make the installation a plug and play process, with very little install time required.  Each kit is also equipped with a brake booster mounting bracket. 

Viair onboard air systems make tire inflation or air locker actuation possible in a very compact space, so you always have air when you need it the most.

Air tanks complete your compressor system by providing your air suspension, air brakes, or air tools with a constant flow of compressed air. Whether you’re looking to do some serious off-roading, drop your ride height to give your vehicle that cool lowered look, Viair has the air compressor systems and accessories you need to get the job done. Even industrial settings and shops can benefit from the presence of an air compressor system.

Whatever the application, the air compressor is only half of the picture. An air compressor cannot run continuously, as they are limited by their duty cycle. So if you need to have a constant and uninterrupted source of compressed air, then you need to add an air tank to your air compressor system.

Air reservoir tanks from Viair are strong, durable and built to last. These air tanks are coated to prevent damage from corrosion and oxidation. Their capacity can range from 1/2 gallon to 5 gallons and are tested to twice their 150 PSI or 200 PSI working pressure. Each air tank features at least 2 NPT ports which range from 1/4 to 3/8 inches.
