Your LEV System Might Be Costing You More Than You Think.

Many businesses consider their Local Exhaust Ventilation (LEV) system only when testing is due or issues arise. However, an inefficient or poorly maintained system can increase energy costs, lower productivity, and put employees at risk, ultimately affecting operations and profitability. Regular attention is essential.
A well-designed LEV system should go beyond legal compliance. It must effectively capture airborne contaminants, protect staff, improve air quality, and operate efficiently to control costs and support business performance. When these standards are not met, expenses can rise quickly.
Small Problems Become Expensive Problems
Many of the issues we discover during inspections begin as relatively minor faults.
These can include:
Damaged or leaking ductwork
Blocked filters
Incorrect airflow
Poor hood positioning
Worn fan components
Systems that have never been rebalanced after workplace changes
If left unresolved, these issues can reduce extraction performance, increase operating costs, and cause unnecessary disruption. Small faults can quickly escalate into significant problems.
Every Workplace Changes
Manufacturing processes change, machinery is updated, production lines move, and new materials are introduced. However, LEV systems are often not redesigned or adjusted to match these changes, leaving them misaligned with current needs.
An extraction system that worked well five years ago may no longer offer adequate protection for your workforce today.
Looking Beyond Compliance
Regular LEV testing is a legal requirement, but it also provides an opportunity to assess system performance and identify opportunities to reduce costs or improve efficiency. Testing should be viewed as more than a compliance check.
Routine maintenance, accurate airflow measurements, and professional inspections help ensure your system continues to protect employees, support productivity, and deliver long-term value.
