Compressed air systems are used in various industries, including food and beverage, manufacturing, automotive, pharmaceutical, and chemicals. However, their efficiency and reliability are often overlooked. Air audits are crucial for optimising these systems. This guide explores how air audits improve your compressed air systems’ performance, efficiency, and compliance. 

Despite being crucial to so many vital processes, the efficiency and reliability of compressed air systems are often overlooked. However, an inefficient system could affect the quality of the air produced, increase energy costs, increase wear to your system, and more. Thankfully, your system can be optimised to ensure a maximum return on your investment, and that process begins with an air audit.

What is a Compressed Air Audit?

A compressed air audit is a comprehensive assessment of your compressed air requirements and the performance of your compressed air system. By thoroughly understanding your compressed air needs, you can ensure you have the appropriate air compressor for your specific needs. Additionally, an audit identifies potential issues within your compressed air system, such as leaks, which, when rectified, can significantly enhance the efficiency and effectiveness of your system.

What Does an Air Audit Involve?

A compressed air audit entails a thorough examination of various aspects of your compressed air system to identify inefficiencies and opportunities for improvement. An air audit will address a number of areas of your compressed air system to identify how it can be better optimised. An air audit will look at the following:

Air Demand and Supply

The audit assesses whether your current compressors are appropriately sized to efficiently meet your air demand. It ensures that you have the right compressors to match demand, optimising energy consumption and reducing operational costs.

Compressed Air Pressure 

Over-pressurisation consumes more energy and increases the risk of leaks and system wear. The audit evaluates your pressure requirements and recommends adjustments to prevent unnecessary energy consumption and potential damage to the system.

Air Leaks

Air leaks are one of the most common sources of energy and financial waste in compressed air systems. The audit identifies these leaks, allowing for prompt repair and minimising energy losses, ultimately improving system efficiency.

Compressed Air System Piping 

The condition and design of piping significantly impact the efficiency of your compressed air system. The audit examines factors such as piping age, sizing, and layout, identifying issues, such as corrosion, incorrect sizing, or excessive bends, that may hinder system performance.

Air Compressor Maintenance 

Regular maintenance is vital for ensuring the longevity and efficiency of your compressor system. The audit reviews your maintenance practices and schedules, ensuring that essential tasks such as changing filters, separators, and lubricants are performed at optimal intervals to prevent downtime and maintain system performance.

How to Conduct a Compressed Air Audit 

Air audits are conducted by specialist air engineers who follow a systematic approach throughout your system. Operators begin by collecting data using specialised tools such as flow meters, pressure gauges, and ultrasonic leak detectors. This data is then analysed to evaluate the system’s overall performance and identify potential leaks or inefficiencies. With the gathered data, compressed air experts can provide personalised guidance on designing a system to meet your needs or optimising your existing system.

Why are Air Audits Essential? 

Air audits are vital diagnostic tools for uncovering inefficiencies within compressed air systems. They are key to optimising efficiency, minimising energy consumption, and extending equipment life. For example, even a minor air leak, though seemingly insignificant, can accumulate into substantial energy wastage over time. By promptly identifying and addressing such issues through regular air audits, operators enhance the reliability and cost-effectiveness of their compressed air system.

Identifying Energy-Saving Opportunities 

Air audits play a crucial role in identifying energy-saving opportunities within compressed air systems. Consider an industrial facility with multiple air compressors running simultaneously. Through an air audit, operators may discover that certain compressors are operating inefficiently due to improper maintenance or outdated equipment. By addressing these issues, their facilities can significantly reduce their energy consumption, helping minimise operational costs.

Optimising System Performance 

Optimising the performance of a compressed air system involves fine-tuning various parameters, such as pressure levels, airflow rates, and equipment settings. For example, by adjusting the pressure setpoints on air compressors to match the actual demand, operators can minimise energy wastage and improve overall system efficiency. Additionally, proper maintenance practices, such as regular filter replacements and leak repairs, are essential for ensuring optimal system performance.

Ensuring Compliance with Industry Regulations 

Compressed air systems are subject to various industry regulations and standards, particularly regarding air quality and energy efficiency. Air audits help ensure compliance with these regulations by identifying areas of non-compliance and recommending corrective actions. For instance, if the compressed air system is used in a food processing facility, it must adhere to strict air quality standards to prevent contamination. An air audit can assess the system’s air quality parameters and recommend measures to meet regulatory requirements.

Key Takeaways for Air Compressor Energy Audit
