What Is LEV Servicing?

LEV servicing (Local Exhaust Ventilation servicing) is the process of maintaining and optimising extraction systems that remove harmful airborne contaminants from the workplace. These systems capture dust, fumes, vapours, and gases at the source to protect employees from inhaling hazardous substances.

Regular servicing ensures that your LEV system operates efficiently and continues to provide effective protection between statutory inspections. Without ongoing maintenance, performance can degrade over time due to blockages, wear and tear, or faulty components — leading to reduced airflow, exposure risks, and non-compliance with HSE standards.

Why LEV Servicing Is Critical for Workplace Safety

LEV systems are essential in any environment where airborne contaminants are generated. Over time, even minor faults such as clogged filters, damaged ductwork, or fan malfunctions can lead to a significant reduction in extraction efficiency.

Proper LEV servicing helps to:

Maintain consistent airflow and contaminant capture efficiency.
Prevent costly system failures and breakdowns.
Protect employee health by ensuring safe air quality.
Extend the lifespan of the LEV system.
Demonstrate ongoing compliance with COSHH Regulation 9.

The Health and Safety Executive (HSE) requires that all LEV systems be properly maintained and kept in an efficient state. Servicing is therefore not just best practice — it is a legal obligation.

What’s Included in LEV Servicing?

At Clean Air 24 Seven, our LEV servicing packages are designed to deliver full system assurance and compliance. Each service is tailored to your equipment type, working environment, and industry needs.

Our LEV servicing process includes:

Visual Inspection and Assessment – We carry out a detailed visual inspection of hoods, ducts, filters, fans, and discharge points to identify signs of wear, corrosion, or damage.

System Cleaning – Dust, debris, and residue are removed from ductwork, filters, and components to restore optimal airflow and efficiency.

Airflow Testing – Using calibrated instruments, we measure airflow velocities and static pressures to confirm that your system meets performance standards.

Component Servicing – Fans, filters, and dampers are checked, cleaned, lubricated, and replaced if required.

Filter Replacement – We supply and fit replacement filters to maintain performance and air purity.

Control System Checks – Control panels, sensors, and alarms are inspected and tested to ensure safe and reliable operation.

System Optimisation – Our engineers make adjustments and recommendations to improve system performance, energy efficiency, and noise levels.

Service Reporting and Certification – On completion, you will receive a detailed service report with findings, measurements, and recommendations for ongoing maintenance or repairs.

This proactive approach ensures that your LEV systems are not only compliant but also operating at peak performance.

The Importance of Preventative Maintenance

Preventative LEV maintenance reduces the likelihood of breakdowns and helps your business stay ahead of compliance requirements. Regular servicing allows small issues to be identified before they become costly problems.

For example:

A small duct blockage can quickly reduce airflow, increasing exposure risk.
A worn fan belt can cause the fan to underperform, affecting extraction efficiency.
A damaged filter can lead to contamination build-up and system strain.

By investing in routine LEV servicing with Clean Air 24 Seven, you protect your workforce, extend the life of your system, and minimise costly downtime.

How Often Should LEV Systems Be Serviced?

While LEV testing is required every 14 months under COSHH, regular servicing should be carried out more frequently — typically every 3 to 6 months, depending on your system type and usage.

For example:

High-use or high-risk systems (e.g., welding or chemical processes) may need quarterly servicing.
Medium-use systems (e.g., woodworking) may require servicing twice a year.
Low-use systems may only require annual servicing.

Our team will assess your site and recommend a servicing schedule that ensures continued safety and compliance throughout the year.
