COMMISSIONING
Commissioning is a critical stage in any LEV system — yet it is often overlooked.
Without proper commissioning, there is no clear benchmark for how a system is intended to perform. This makes it difficult to determine whether it is operating effectively or simply meeting general minimum standards.
A properly commissioned system provides confidence that it is doing what it was designed to do — controlling contaminants effectively and protecting those working around it.
What Is Commissioning?
LEV commissioning is the process of verifying that a system has been installed correctly and is performing in line with its design.
This includes:
-
Measuring airflow throughout the system
-
Setting and balancing airflow rates
-
Confirming hood performance and capture effectiveness
-
Checking overall system operation against design intent
The result is a set of baseline performance values that future testing can be measured against.
Why Commissioning Matters？
Without commissioning, LEV testing is often carried out against general guidance rather than system-specific performance.
This can mean:
-
Systems appearing compliant, but not performing as intended
-
No clear benchmark for future testing
-
Difficulty identifying whether performance has improved or declined over time
Commissioning ensures that your system has a defined standard — specific to your process and design.
Retrospective Commissioning
In many cases, systems have been installed and used for years without ever being properly commissioned.
We regularly carry out retrospective commissioning, working back from the existing system to understand:
-
What the system was designed to achieve
-
How it is currently performing
-
What adjustments or improvements are required
This process often highlights areas where remedial work is needed to bring the system up to the required standard.
A Practical, System-Focused Approach
We take a practical approach to commissioning, focusing on how systems perform in real operating conditions — not just theoretical values.
Where design information is available, we use this to establish accurate performance benchmarks. Where it is not, we work with the system as installed to define realistic and effective performance criteria.
What You Get
-
A clear set of system performance benchmarks
-
Confidence that your system is operating as intended
-
A solid foundation for future LEV testing and maintenance
-
Clear identification of any issues requiring attention
