LEV SYSTEMS
Targeted Fume, Dust & Vapour Extraction
Protecting workers from airborne hazards is not optional, it is a legal requirement. SA ENDURE LEV (Local Exhaust Ventilation) systems are engineered to capture harmful fumes, vapours and dust directly at the point of generation, before they can enter the breathing zone.
Built for the most demanding industrial environments, our LEV systems are fully compliant with ISO 21904-1:2020 and HSG258. HSG258 is the HSE’s guidance document on controlling exposure using LEV. Together, these standards give you the confidence that your team is protected and your operations meet the required standard.
Our LEV Range
SA ENDURE LEV systems are available in portable and mobile configurations to suit different site requirements and operator needs.
The Portable LEV System is designed for single operators working in tight-access or confined spaces, providing effective extraction where larger units cannot be deployed. The Mobile LEV System is a modular unit capable of supporting multiple extraction points, suited to larger projects and shared worksite use.
All systems are compatible with the SA ENDURE PVC Flexible Duct System, which extends and adapts extraction to reach specific areas of a worksite.

What is Local Exhaust Ventilation?
Local exhaust ventilation works by extracting contaminants directly from the point of generation, preventing them from dispersing into the wider workspace and the breathing zone of workers. It is one of the most effective methods of hazard control under COSHH regulations and is a requirement for many industrial operations.
Unlike general ventilation, which dilutes contaminants across a space, LEV removes them at source. This makes it significantly more effective at protecting individual workers from harmful exposure.
When is an LEV System Required?
LEV systems are typically required for tasks that generate hazardous airborne substances that cannot be adequately controlled through general ventilation alone. This includes welding and hot work, cutting, grinding and blasting, and painting and coating processes.
Post-2019 HSE guidance made clear that general ventilation is no longer considered sufficient for welding operations. LEV is now the expected standard for controlling exposure to welding fumes and respirable particles.
Where SA ENDURE LEV Systems Are Used
- Welding & Hot Work: Welding fumes and respirable particles generated during MIG, TIG and MMA welding and cutting operations are captured directly at source. This reduces exposure to hazardous metal fumes and fine particulates.
- Dust Extraction: From general industrial dust to fine respirable particles such as silica dust produced during blasting and cutting, SA ENDURE dust extraction systems are designed to capture contaminants before they reach the breathing zone.
- Painting, Coating & Vapour Removal: During painting and coating operations, volatile organic compounds (VOCs) and other vapours present a significant inhalation risk. SA ENDURE vapour extraction removes these contaminants efficiently, protecting workers and maintaining compliance with workplace exposure limits.
Compliant with Industry Standards
SA ENDURE LEV systems are compliant with ISO 21904-1:2020 and HSG258. These standards govern the design, performance and testing of LEV equipment used in industrial environments. Compliance demonstrates that your extraction system is fit for purpose and capable of adequately protecting workers. This gives both operators and site managers confidence that the correct standard of protection is in place.
