Regular audits are recommended annually or biannually and immediately following system modifications or when operational inefficiencies emerge. Early detection of leaks and inefficiencies prevents excess energy costs and equipment wear.
Air compressors are essential in many industrial and commercial facilities, providing the necessary compressed air for various processes. Ensuring these systems function properly is crucial to optimize energy consumption and reduce operating costs.
This blog post will explore when to operate an air compressor audit, the different types of evaluations, the audit process, and common questions about air compressor audits.
Why Conduct an Air Compressor Audit?
Conducting an air compressor audit is essential for several reasons:
- Energy Efficiency: Up to half of all produced compressed air can be wasted due to inefficiencies and leaks. Identifying and addressing these issues can significantly reduce energy consumption.
- Cost Savings: Reducing energy waste translates into lower utility bills and operational costs.
- System Reliability: Regular audits help maintain the system's reliability, preventing unexpected downtime and costly repairs.
What are the main types of air compressor’s evaluations?
Compressed Air Assessment
A compressed air assessment is a quicker, less expensive, and simpler method that primarily focuses on the supply side of the system. It aims to rapidly gauge the efficiency and effectiveness of compressed air usage.
Typically conducted by manufacturers or internal teams, assessments provide immediate insights. These are beneficial for operators seeking a straightforward snapshot of system performance to identify obvious inefficiencies or confirm sound operation at a lower cost.
Air Compressor Audit
In contrast, an air compressor audit is a comprehensive, in-depth analysis performed by specialized audit teams. These audits require a longer timeframe, often between one to two weeks, and involve placing multiple data loggers throughout a facility to gather detailed information on various parameters such as power output, air flow rates during peak and off-peak times, and equipment conditions.
This data collection enables auditors to evaluate system dynamics thoroughly, detect hidden energy waste, identify leaks, pinpoint excess or inappropriate compressed air usage, and assess equipment performance.
How long does a typical air compressor audit take?
A comprehensive audit generally requires up to one week of onsite evaluation, depending on system size and complexity, enabling thorough inspections and data collection.
The Audit Process
System Understanding and Site Survey
The initial step involves a professional assessment of the layout, equipment placement, and system dynamics. The goal is to verify that compressors are installed optimally and functioning cohesively within the system.
Leak Detection
Since leaks are primary culprits of wasted compressed air, auditors meticulously check pipes, valves, fittings, and tools to identify and quantify air losses.
Pressure and Flow Analysis
Evaluations ensure that the system operates at appropriate pressure levels without artificial demand, unnecessary pressurization that causes compounding energy waste.
Filter and Dryer Inspection
Compressed air quality hinges on effective filtration and moisture removal. Clogged filters and ill-suited dryers force compressors to work harder, risking poor air quality and equipment damage.
Sourcing Reliable Spare Parts
Adequate storage tanks reduce the frequency of compressor cycling, thus improving efficiency and prolonging equipment life. Audits analyse tank volumes relative to operational needs.
Operational Habits Assessment
Many facilities unknowingly run compressors during non-operational hours, such as nights or weekends, incurring needless costs. Transitioning to scheduled shutdowns during these times can yield sizable savings.
Recommendations and Follow-ups
Beyond identifying issues, audits propose actionable upgrades or behavioral changes. Follow-up audits validate the effectiveness of implemented improvements to ensure continuous efficiency gains.
When to Operate an Air Compressor Audit
Running an air compressor without periodic audits is like driving a car indefinitely without a tune-up: avoiding audits causes inefficiencies and hidden issues accumulate over time, leading to wasted fuel (energy), premature wear, and unexpected breakdowns. Therefore, audits should be scheduled:
- Annually or Biannually: Depending on system complexity and usage intensity, regular audits help catch gradual efficiency losses.
- After System Changes: When adding new equipment or reconfiguring the air system, auditing ensures the changes integrate smoothly.
- Following Performance Declines: If noticing rising energy costs or inconsistent air pressure, audits can diagnose root causes.
- Pre-Budget Cycles: To plan capital or operational expenditures effectively based on identified needs.
- Before Major Maintenance or Upgrades: To prioritize interventions with the greatest cost-benefit ratio.

Air compressor audits serve as essential diagnostics to uncover hidden inefficiencies that inflate operational costs and stress equipment. Combining audits with systematic maintenance creates a holistic approach, akin to both inspecting and regularly servicing a high-performance engine, that maximises reliability, reduces energy expenses, and sustains long-term productivity.
Common Questions About Air Treatment Systems
Leaks in pipes, valves, and fittings; operating at unnecessarily high pressures; clogged filters; insufficient air storage; and compressors running during off-hours are leading factors contributing to energy waste.
Steps include a system survey, leak detection, pressure and flow assessments, filter and dryer evaluation, checking storage capacity, reviewing operational patterns, and finally making tailored recommendations and follow-up plans.
Maintenance activities like oil changes, lubrication, filter replacements, and moisture management ensure the compressor operates smoothly. This proactive care supports audit findings by preventing performance degradation and extending equipment lifespan.
