Choosing An Air Compressor Kit for Your Air Bags

Are you thinking about getting an air compressor kit for your air bags and feeling a little overwhelmed by all the options? Don’t worry, you’re not alone. Let’s take a look at the differences and answer some of the important questions you will need to ask yourself when selecting an air compressor kit for your air bags.

Which Brand of Air Compressor Kit?

Air Compressor kits are Universal. Air spring and air bag load support kits use 1/4 inch airline tubing, so the air compressors will work with other brands of air bag kits. Do you have Firestone air bags but like the features of an Air Lift compressor kit? Did you buy a truck that has Air Lift air bags or Hellwig air springs on it, but want to install a Firestone air compressor kit? No worries, one brand will work another brand of air springs. Which brand to choose is a personal preference. We have satisfied customers using Firestone, Air Lift and Viair air compressor kits. You really can't go wrong with which brand you select. Find the one that has the features your require and fits within your budget.

wireless or analog air controlWireless or Analog?

wireless air compressor kits

Wireless air compressors use the latest technology and allow you to inflate and deflate your air bags from inside or outside of your truck. This can come in handy when you want to level out the rear of your truck by allowing you to stand next to the back of the truck and see the change in ride height when inflating or deflating your air springs.  They do cost more, but the extra money you spend on a wireless kit can be made up in the reduced time and cost to install the system. Wireless air compressor kits do not require any lines to be run into the cab of your truck, so the install is much less time consuming than with other systems.

Pros of Wireless Air Compressors systems:

 

  • Easy to install – no wires to run into cab
  • Inflate / deflate your airbags from outside your truck
  • Memory settings for air pressure

analog air compressor kit

Analog air compressors install inside the cab of your truck and are controlled by a toggle switch or button and display the air pressure on a gauge with a needle. Analog systems have been around for years and typically cost less. They will take longer to install than a wireless system because you have to run lines into the cab for the gauge. If you are installing it yourself and have the extra time, it can be less expensive to run an analog system.

Pros of Analog Air Compressors

 

  • Cost less
  • Tried and True – Inflating air bags for decades
  • Expandable – Allows the use of air tanks

single or dual path air compressorSingle or Dual Path Air Compressor?single path air compressor

Single path air compressors inflate both air bags at the same time with the same amount of air pressure.  This provides equal inflation and is designed for use with evenly distributed loads like travel trailers or 5th wheel trailers. If you tow anything with a trailer hitch, a single path system will work well and provide even air pressure.


Single path common uses (Even loads)

  • Travel Trailers
  • Boat Trailers
  • 5th Wheel and Goosneck Trailers
  • Utility and work trailers
  • Horse trailers

dual path air compressor

Dual paths air compressor kits allow you to inflate your air bags with different air pressure amounts.  In the diagram above, the air bag with 45 psi would be on the side of your truck with a water tank or heavy tool box. With a dual path system you can do side-to-side or front-to-back leveling. They are commonly used when you have more weight on one side and need to add more air pressure to one air spring to adequately level your truck. If you have a work truck with cargo on one side or a pickup truck with a Lance slide-in truck camper with luggage and supplies on one side, a dual path system is for you.

Dual Path Common Uses (Uneven loads)

  • Work trucks
  • Flatbed trucks
  • Motorhomes
  • Slide-in Campers

standard or heavy duty compressorStandard Duty or Heavy Duty Air Compressor?

How often you tow is the main factor in determining if you need a standard or heavy duty air compressor. If you are a holiday traveler and only tow your camper once a month during the summer, you will be fine selecting a standard duty air compressor kit. If you have a work truck that is inflating the air bags daily or want more durability and flexibility with your system, we recommend a heavy duty setup with a higher duty cycle that will allow you to run the system more frequently. A heavy duty air compressor will inflate your air springs quicker and often to a higher psi than a standard duty one. If you use your air compressor to pay the bills, have a motorhome that requires higher psi, or are frequently using your air system, we recommend investing a little more upfront for a heavy duty system.

We hope this helps you determine which air compressor system will work best for your needs. If you have any questions, feel free to contact us at 1-800-358-4751. We have been selling and installing air bags and air compressors in our shop for years.

What is Air Compressor Duty Cycle?

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.

What is the Duty Cycle of an Air Compressor?

Many Air Compressors are not built to be run continuously and some need time to rest between uses.


Air Compressor The term Duty Cycle refers to the percentage of time an Air Compressor can run before needing time to cool down. The Duty Cycle of an Air Compressor is often expressed as a percentage of a certain amount of time, usually being 10 minute periods. That is, the Duty Cycle measures the proportion of time an Air Compressor can run against the amount of time needed for it to cool.

For example, the Firestone Super Heavy Duty Air Compressor has a 30% Duty Cycle and can be run for 3 minutes, it must then rest for 7 minutes. However, the Firestone Ultimate Duty Air Compressor has a 100% Duty Cycle and can be run continuously without a cool down time. These air compressors usually cost a little more but they are a time efficient alternative to lighter duty Air Compressors.Air Compressor

The Duty Cycle of an Air Compressor is calculated by dividing the total run time by the amount of time the compressor can run before resting. For example:

D = R / T with ‘D’ being Duty Cycle,‘R’ being run time before resting and ‘T’ being the total time.

30% Duty Cycle = 3 minutes run time / 10 minutes total – So an Air Compressor that can run for three minutes before needing to rest for 7 minutes has a 30% Duty Cycle.

Conversely, by knowing the Duty Cycle the run time can be determined by multiplying the Duty Cycle by the total time (usually 10 minutes). For example:

R = D x T

3 minute run time = 30%(.3) Duty Cycle x 10 minutes total – So an Air Compressor that has a Duty Cycle of 30% can run for 3 minutes before needing to cool for 7 minutes.

The below table is based on a 10 minute total time.
