At NCA Ltd., we recognize that when something goes wrong with your compressed air system, it can quickly impact productivity, efficiency, and costs. The good news? Most common compressor issues are preventable or easily fixed with the right knowledge and maintenance approach.
Below are some of the most frequent problems we see in compressed air systems—and how to address them.
1. Air Leaks
The Problem:
Air leaks are one of the biggest (and most expensive) issues in any compressed air system. Even small leaks can lead to significant energy loss, increased run time, and higher operating costs. Many facilities neglect to address air leaks and this leads to energy loss, increased costs and headaches!
How to Fix It:
- Perform regular leak audits using ultrasonic leak detectors – at NCA Ltd., we offer ultrasonic leak detection and air audits
- Repair or replace faulty fittings, hoses, and connections as soon as you see wear/tear
- Implement a routine maintenance schedule to catch leaks early – we work with clients to craft personalized preventative maintenance programs
Pro Tip: A system with multiple small leaks can waste thousands of dollars annually in energy costs.
2. Pressure Drops
The Problem:
Low or inconsistent pressure can disrupt tools and processes, leading to poor performance and downtime. Inconsistent pressure can impact tool performance and efficiency, product quality, and production timelines.
Common Causes:
- Undersized/incorrect piping
- Clogged/dirty filters
- Excessive demand on the system
How to Fix It:
- Check and replace filters regularly – clean filter = clean/efficient air
- Ensure piping is properly sized for your specific application
- Evaluate system demand vs. compressor capacity
- Keep an eye on system demand. You may want to invest in a variable speed compressor if demand fluctuates
3. Moisture in Your System
The Problem:
Compressed air naturally contains moisture, which can cause corrosion, damage equipment, and contaminate end products.
How to Fix It:
- Install or upgrade air dryers (refrigerated or desiccant)
- Drain receivers and filters regularly – consider installing a zero loss drain
- Ensure condensate drains are functioning properly
Pro Tip: Moisture issues often point to undersized or malfunctioning dryers.
4. Overheating Compressors
The Problem:
Excess heat can reduce compressor lifespan and lead to unexpected shutdowns – especially during the summer months/heat spells!
Common Causes:
- Poor ventilation – location and installation of your compressed air system is crucial
- Dirty coolers or filters
- High ambient temperatures
How to Fix It:
- Clean coolers and intake filters
- Improve airflow and ventilation around the unit
- Keep ambient temperatures within recommended limits
5. Excessive Energy Consumption
The Problem:
Compressed air is one of the most expensive utilities in a facility. Inefficient systems can dramatically increase operating costs. Understanding your demand profile is important to ensure you have the correct system in place.
Common Causes:
- Air leaks – often overlooked and can lead to significant issues if not addressed
- Running at higher pressure than necessary – always check CFM and PSI requirements for your application
- Outdated or improperly sized equipment – inefficiency may be a sign its time for an upgrade!
How to Fix It:
- Fix leaks ASAP and optimize pressure settings
- Upgrade to energy-efficient compressors (e.g., variable speed drives)
- Conduct an energy audit of your system. NCA Ltd can help facilitate this audit.
6. Contaminated Air
The Problem:
Oil, dirt, and other contaminants can damage equipment and compromise product quality. Compressed air can be up to 8x more contaminated than ambient air without proper drying and filtration.
How to Fix It:
- Install proper filtration (pre-filters, coalescing filters, after-filters)
- Install dryers, if necessary
- Maintain and replace filters on schedule
- Ensure oil separators are functioning correctly
7. Improper System Sizing
The Problem:
An undersized system struggles to meet demand, while an oversized system wastes energy and increases wear. Facility managers often overlook the importance of ‘right-sizing’ their compressed air system.
How to Fix It:
- Conduct a compressed air demand analysis with the help of NCA
- Match compressor capacity to actual usage – ensure you know your demand profile/usage requirements
- Consider future expansion when designing your system
Most compressor system issues don’t happen overnight—they develop over time due to lack of maintenance, poor system design, or inefficiencies that go unnoticed.
A proactive approach, including routine inspections/preventative maintenance programs, and proper equipment selection can significantly extend the life of your system while reducing costs and downtime.
At NCA Ltd., we help businesses across Ontario optimize their compressed air systems with expert support, high-quality equipment, and ongoing maintenance solutions.
