LEV System Design Consultancy
McCarthy Environmental Ltd provides professional LEV design services for businesses requiring effective, compliant, and efficient air pollution control solutions. With over 25 years of industry experience, we design bespoke Local Exhaust Ventilation (LEV) systems tailored to the specific requirements of industrial, commercial, and educational environments across the UK.
Our BOHS P602-qualified system designers work closely with clients to develop practical extraction solutions that effectively control dust, fumes, oil mist, vapours, and other airborne contaminants at source. Every system is designed to meet current COSHH regulations and HSE guidance while also considering operational efficiency, energy usage, maintenance accessibility, and long-term system performance.
We provide comprehensive design consultation packages covering every stage of a project, from initial site surveys and concept development through to detailed system specifications and technical drawings. Using advanced 2D and 3D modelling software, we create fully detailed designs that allow clients to visualise the proposed system layout, airflow performance, ducting arrangements, extraction points, and equipment integration before installation begins.
Our design team carefully assesses workplace processes, contaminants, machinery, production layouts, and environmental factors to ensure each LEV system delivers optimal extraction performance while integrating efficiently into existing operations. We can design systems for a wide range of applications including welding fume extraction, dust extraction, oil mist filtration, pharmaceutical containment, woodworking extraction, and specialist industrial processes.
In addition to complete turnkey designs, we also support clients with upgrades, system modifications, performance improvements, and replacement designs for existing LEV installations. Our expertise allows us to identify opportunities to improve airflow efficiency, reduce energy consumption, and enhance overall system reliability and compliance.
McCarthy Environmental Ltd works with leading manufacturers including Nederman, oberA, ESTA, BOFA, Filtermist, Airbench, Absolent, Dustcontrol, and Kemper, alongside our own bespoke manufacturing capabilities. This enables us to provide fully tailored solutions using the most suitable equipment and technologies for each individual project.
By combining technical expertise, practical industry knowledge, and a strong focus on compliance and performance, McCarthy Environmental Ltd delivers LEV design solutions that help businesses create safer working environments, protect employee health, and maintain long-term operational efficiency.

BOHS Endorsed LEV Training Centre
The McCarthy Environmental Centre of Excellence, located at our Swan Valley headquarters, is unique in the region and provides a variety of LEV (local exhaust ventilation) and Occupational Hygiene courses.
Absolent A•erity Range
Our flexible design allows for customised solutions tailored to specific requirements. Depending on airflow and particle load, units can be adjusted or converted, handling 500–40,000 m³/h of airflow and particle loads from 70 mg/m³ to 10 mg/m³. Each system is modular, with a main unit configured based on flow and particle load, and additional sub-units can be added or removed as future needs arise. All units feature IE5-class EC motors for optimized energy efficiency and safer operation.
Absolent A•line Range
With A•line, you get a versatile, adaptable filter suited to your specific needs. It works equally well for small, demanding machines or those producing a moderate amount of oil mist in the workshop. A•line is future-ready—changes in coolant, cutting speed, or pressure won’t affect its performance. Plus, it features intelligent monitoring equipment that delivers the right amount of airflow exactly where and when it’s needed.
