LEV (Local Exhaust Ventilation) fume extraction systems are designed to remove hazardous fumes directly from the source before they can be inhaled. These systems protect employees from exposure to harmful substances such as welding fumes, soldering fumes, chemical vapours, and solvent-based mists.

Fumes may contain toxic gases, ultrafine particles, and carcinogens. Without proper extraction, exposure can lead to serious health issues including respiratory problems, neurological damage, or cancer. Fume extraction is essential for employee health and legal compliance.

Fume extraction is essential in many industries, including:

• Welding and metal fabrication
• Electronics and PCB manufacturing
• Chemical processing
• Automotive repair and paint spraying
• Laboratory work and research facilities
• Beauty and nail salons (acrylic fumes)

Yes. The Health and Safety Executive (HSE) requires employers to control exposure to hazardous substances under the COSHH Regulations. LEV fume extraction systems are a primary method for meeting these legal duties.

By law, all LEV systems — including those used for fume extraction — must be tested by a competent person at least once every 14 months. Certain high-risk environments may require more frequent checks.

A typical inspection from LEV Tec Solutions includes:

• Airflow and capture velocity checks
• Visual inspections of hoods, filters, ductwork, and fans
• Smoke testing or tracer gas testing (where applicable)
• Performance comparison with system design specifications
• A full report and compliance certification

We handle systems designed for:

• Welding and brazing fumes
• Solvent fumes and VOCs (Volatile Organic Compounds)
• Soldering and flux fumes
• Acid and alkaline vapours
• Paint spray and isocyanate mists

If your system fails a compliance check, we’ll clearly identify the issue and offer practical solutions — from filter changes to complete system redesigns — to help you achieve safe, compliant operation.

Yes. In addition to testing, LEV Tec Solutions designs, installs, and commissions complete LEV fume extraction systems tailored to your specific processes and workspaces.
