VMAC surveyed 1,464 visitors on the VMACAIR.com website to ask the question, &#;How many years do you expect your truck mounted air compressor to last?&#; The poll results showed a clear winner with 40.51% of respondents choosing 6-10 years.
When combining those results with the 19.19% of respondents who chose 1-5 years and the 17.76% who chose 11-15 years, a whopping 77.46% expect their truck mounted air compressor to last within the 1-15 years range.
These results align with VMAC&#;s State of The Mobile Air Industry survey results, which reveal the average age of service trucks is under 10 years, and is consistent with our understanding of the relationship between air compressors and work trucks. Fleet managers and owners typically install truck mounted air compressors on brand new work trucks, then expect those air compressors to last the life of the truck. The air compressors are then retired or resold at the same time as the service vehicle.
However, the poll results also revealed surprisingly high and low expectations of truck-mounted air compressors.
Nearly one-fifth of all respondents expect their truck-mounted air compressor to only last 1-5 years, suggesting a massive turnover of compressed air on these trucks. Without further context from these respondents, it&#;s impossible to know why their expectations are so low. Still, it seems probable that these survey respondents purchase older trucks that turnover regularly or are only familiar with low-quality, temporary air solutions.
Another significant number of respondents expect their truck mounted air compressor to last more than 25 years. While this is potentially possible with the right air compressor system and preventative maintenance schedule, it is well above the average expectations.
Of course, the work truck industry has always had individuals who are proud of their ability to maintain vehicles and equipment for several decades, and it&#;s not that surprising that a similar cohort would expect the same lifespan from their truck mounted air compressor.
When Should I Replace My Truck Mounted Air Compressor?
If you&#;re wondering when you should replace a truck mounted air compressor, the short answer is, &#;when you need to.&#; If your air compressor is functioning properly, there is no need to replace it early or on a pre-determined schedule.
Chris Marshall supports this sentiment in Service Truck Magazine, saying, &#;I don&#;t think there are general guidelines about when an air compressor should be retired. I&#;ve never read or been informed about any, at any rate. If the condensation in the tank doesn&#;t have flakes of rust in it, the air seals are still holding, and the motor is running strong, I&#;d just keep right on using it.&#;

Of course, based on their own equipment estimates, many fleets replace their truck mounted air compressors at regular intervals. Fleets outfitted with rotary screw air compressors can typically cycle their air compressors at the same time as their trucks, while those with reciprocating air compressors should plan for a much shorter interval.
What Factors Impact The Lifespan of Air Compressors?
Four primary factors impact the lifespan of every vehicle mounted air compressor. By understanding these factors better, fleet managers and air compressor owners can choose the best air compressor for their long-term needs and extend the longevity of their systems.
Rotary Screw vs. Reciprocating
The first and foremost factor in air compressor longevity is the compressor type. Rotary screw air compressors are hardy and powerful systems that have a significantly longer lifespan than reciprocating air compressors. If you plan to use your truck mounted air compressor for more than 5 to 10 years, a rotary screw air compressor is the smart way to go.
Product Quality
Product quality has a direct impact on air compressor longevity. For this reason, fleet managers and owners must look closely at the manufacturer or company they are purchasing from. Here are a couple of things to look for:
- Manufacturing Location&#; Many people within the industry believe that air compressors manufactured start-to-finish in North America are better quality than air compressors imported or only assembled in North America. While it&#;s impossible to collect data that would prove this sentiment, keep it in mind when assessing your options and choose truck mounted air compressors that are genuinely manufactured within North America by a company such as VMAC.
- Quality Control&#; Manufacturers who are serious about quality have stringent quality control management processes. Companies who take this seriously will maintain their ISO : certification, making them easy to identify. Ask to see a company&#;s ISO : certification before purchasing an air compressor from them.
Maintenance
Truck mounted air compressors need to be regularly maintained, following the maintenance schedule outlined by the manufacturer. This maintenance helps keep the air compressor in peak working condition and helps prevent unexpected breakdowns. As the saying goes, &#;the best downtime is scheduled downtime.&#; Learn more about rotary screw air compressor maintenance schedules.
Working Conditions
An air compressor&#;s working conditions will also have some impact on its lifespan. For example, an air compressor that sits in the corner of a clean and tidy shop can easily last several decades due to its pristine surroundings. However, truck mounted air compressors are subjected to weather, road wear, vibrations, dirt, grime, and other harsh elements throughout the course of day-to-day work.
Protective covers and quality compressor design can help minimize the wear and tear caused by these working conditions, but it is important to recognize that harsh mobile environments will impact air compressor longevity.
What Do Industry Warranties Say About Air Compressor Lifespans?
Manufacturer warranties for rotary screw and reciprocating air compressors can help identify reasonable lifespan expectations for these mobile compressors.
Rotary Screw Air Compressors
All three major truck mounted air compressor manufacturers in North America, including VMAC, offer a limited lifetime warranty on their rotary screw air ends. This warranty makes sense, as quality rotary screw air compressors can easily last the lifespan of the truck they are installed on.
Rotary screw air compressors are therefore the best option for fleet managers, operators, and owners who want their air compressor to last the lifespan of their truck&#;whatever that vehicle cycle time is.
However, it&#;s important to recognize that the air compressor itself is only one part of a larger system. Other components in the system may not be as hardy, which is why it&#;s critical to take care of truck mounted air compressors and follow the manufacturer&#;s maintenance schedule.
Reciprocating Air Compressors
SGS Engineers states that reciprocating air compressors can have a life expectancy of 10 to 15 years. But our field experience at VMAC suggests that reciprocating air compressors rarely last this length of time, and 5-10 years is a more realistic estimate with appropriate maintenance.
This shortened lifespan may be due to the more challenging conditions that truck mounted equipment endures compared to more stationary reciprocating air compressors. In addition to significant movement and vibration, vehicle mounted air compressors are often subjected to extreme climates and environments.
Conclusion
VMAC&#;s web poll has revealed that a significant majority of respondents expect their truck mounted air compressor to last somewhere between 1 to 15 years, with the largest single segment of respondents expecting their air compressor to last 6-10 years.
Truck mounted air compressors should meet these expectations easily, as long as fleet managers and owners choose high quality, rotary screw compressors and perform the scheduled preventative maintenance.
