What Is a Compressed Air Audit?

A compressed air audit is a systematic evaluation of your compressed air system designed to identify inefficiencies and improvement opportunities. Audits may include leak detection, pressure and flow measurement, data logging, system analysis, and recommendations for improving efficiency, reliability, and performance.

The U.S. Department of Energy estimates that up to 50% or more of the energy required to run a 100 HP air compressor is wasted.

Comairco’s compressed air audits thoroughly evaluate your entire compressed air system to identify opportunities to maximize efficiency, reduce waste, and lower energy, maintenance, and equipment costs. These audits provide precise, data-driven insights into your system’s current condition—empowering you to optimize performance, prioritize upgrades, and ensure your system operates at peak efficiency.

The filter housing is a large, vertical, mint-green component connected to heavy-duty piping and valves. In the background, industrial machinery is visible, including a green Sullair system and electrical control panels inside a manufacturing facility context.

Benefits of a Comairco Compressed Air Audit:

Reduce operating costs by 25% to 50%
Cut maintenance costs by 10% to 80%
Obtain the most accurate data on your system’s current performance
Receive comprehensive documentation on power usage and system interrelationships
Conduct the audit without any downtime or disruption to productivity
Identify projects that may qualify for utility rebates, reducing upfront costs

Additionally, we offer three levels of air system audits, all aligned with Department of Energy standards—providing tailored solutions to meet your specific needs.

A compressed air audit conducted by Comairco’s team of certified auditors is the most effective way to maximize your system’s efficiency. Designed to identify energy-saving opportunities, a compressed air energy audit often uncovers simple yet impactful solutions—such as minor piping adjustments, cost-effective compressor control tweaks, or adding storage capacity paired with precision flow controllers. Every compressed air system is unique, and our audits are tailored to address your specific needs for optimal performance.

Often, compressed air audits reveal enough savings to allow compressors to be turned off entirely. These audits can be integrated into existing maintenance contracts, enabling regular re-assessments as your facility, systems, environment, and compressed air requirements evolve over time.

How Much Does a Compressed Air Audit Cost?

Audit pricing is custom-quoted based on facility size, total horsepower, and operational complexity. Most facilities see complete payback within months through energy savings alone.

Audit Level	Typical Duration	Use Case
Level 1 – Walkthrough	1 day	Quick efficiency check
Level 2 – System Assessment	2–5 days	Data-driven analysis
Level 3 – Full Audit	7–14 days	Comprehensive optimization

Many compressed air audit recommendations may qualify for utility energy rebates in Maine, including programs from Efficiency Maine, helping reduce project costs and improve return on investment.

Compressed Air Audit Levels

COMAIRCO offers multiple audit levels to match your facility’s needs and operational complexity.

Level 1 – Walkthrough Evaluation

A high-level assessment that identifies obvious issues such as leaks, pressure losses, improper controls, inadequate storage, and other opportunities for improvement.

Level 2 – System Assessment

A detailed review that includes system measurements, operating data analysis, pressure profiling, and recommendations for efficiency improvements.

Level 3 – Comprehensive System Audit

An in-depth evaluation utilizing extended data logging, system performance analysis, and baseline development to support major optimization initiatives and capital planning.

Serving Industrial Facilities Across Maine

COMAIRCO provides compressed air audit services for facilities throughout Maine, including Portland, Bangor, Lewiston, Auburn, South Portland, Biddeford, Augusta, and surrounding communities. Whether you operate a manufacturing facility, food processing plant, wood products operation, paper mill, or industrial production site, our team can help identify opportunities to improve compressed air system performance and reduce operating costs.

Phase 1: Advanced Tool Deployment

We connect data loggers to critical points across your system.

Pressure Sensors: Track localized pressure drops and stability fluctuations.
Flow Meters: Measure actual air consumption throughout the distribution lines.
Power Meters: Record continuous energy draw from your air compressor units.

Phase 2: Real-Time Performance Baselining

Our data logging instruments record live metrics with zero interruption to your daily production.

CFM Tracking: Captures actual airflow utilization spikes across varying shifts.
Energy Profiling: Logs real-time electrical power consumption against systemic demand.
Pressure Profiling: Documents system pressure behavior during peak and low-use hours.

Phase 3: Demand Pattern Analysis

Our engineering team compiles the logged telemetry data to uncover hidden system behavior.

Fluctuation Identification: Isolates operational gaps where air supply mismatches demand.
Inefficiency Pinpointing: Tracks exact locations of severe air leaks and artificial demand.
Control Evaluation: Assesses if current compressor controls are properly configured.

Phase 4: Control Strategy & Optimization

We use the finalized baseline profile to develop custom control strategies.

Targeted Adjustments: Outlines exact recommendations to improve overall plant efficiency.
Validation Planning: Sets an accurate performance metric to verify future energy savings.

Compressed air is one of the most expensive sources of energy in a plant. The overall efficiency of a typical compressed air system can be as low as 10%–15%. For example, to operate a 1-horsepower (hp) air motor at 100 psig, approximately 7–8 hp of electrical power is supplied to the air compressor.

Turn Audit Results into Energy Savings

Many facilities can achieve substantial savings after implementing audit recommendations. By correcting inefficiencies, optimizing controls, addressing leaks, and improving system design, organizations often reduce compressed air energy costs while improving overall reliability and productivity. COMAIRCO works with your team to prioritize recommendations and develop practical solutions that deliver measurable results.

Frequently Asked Questions:

How long does a compressed air audit take?

A compressed air audit timeline depends on the level of analysis. A Level 1 walkthrough evaluation can typically be completed in one day. A Level 2 system assessment usually takes 2–5 days, while a Level 3 comprehensive system audit may require 7-14 days to allow for detailed data logging and analysis of system performance over time.

How much energy can a compressed air audit save?

A compressed air audit can typically identify opportunities to reduce energy consumption by 25% to 50%, depending on system condition and existing inefficiencies. Many facilities discover savings through leak reduction, improved controls, optimized pressure settings, and better system alignment.

What is included in a compressed air audit?

A compressed air audit includes a comprehensive evaluation of your system’s supply and demand, including compressors, air distribution, storage, and end use. Depending on the audit level, it may also include leak detection, pressure and flow measurement, data logging, system modeling, and a detailed report with recommendations to improve efficiency, reliability, and performance.
