Extraction Systems & Units

When running CNC machines at high speeds or with high coolant pressure, or during die casting or hardening, the machines can produce thick oil smoke made of tiny particles. These particles can penetrate surfaces and even enter the bloodstream. A similar issue occurs with minimal quantity lubrication (MQL). To effectively remove this type of pollution, a robust filter like A•smoke is essential.

McCarthy Environmental Ltd provides specialist LEV interfacing solutions designed to improve the efficiency, sustainability, and performance of Local Exhaust Ventilation systems across a wide range of industrial and manufacturing environments. 

Our electrical interfacing systems intelligently connect extraction equipment directly to production machinery, ensuring LEV systems only operate when required, helping businesses significantly reduce energy consumption, operating costs, and unnecessary equipment wear.

In many production facilities, extraction systems continue running throughout the entire working shift, even during machine downtime, tool changes, or production pauses. This results in excessive energy usage, increased CO₂ emissions, avoidable noise pollution, and additional strain on extraction equipment. Our LEV interfacing solutions are designed to eliminate this inefficiency by automatically controlling the operation of extraction systems based on machine activity.

When production equipment is in operation, the LEV system automatically activates to provide effective airborne contaminant control. Once machinery stops, the extraction system continues operating for a programmed clearance period before shutting down safely in line with HSG258 guidance. This ensures harmful dust, fumes, and airborne particulates are fully extracted while preventing unnecessary system runtime.

LEV interfacing offers a wide range of benefits for businesses looking to improve workplace efficiency and sustainability. By reducing extraction system operating times, organisations can significantly lower electricity usage, reduce carbon emissions, and support environmental management objectives such as ISO 14001 accreditation. Many businesses experience a rapid return on investment through lower energy costs, with typical ROI periods ranging from 3 to 24 months, depending on system usage and operating conditions.

In addition to energy savings, interfacing also helps create quieter and more comfortable working environments by reducing unnecessary extractor noise during non-productive periods. This can improve employee wellbeing, reduce workplace noise pollution, and minimise the likelihood of operators switching extraction systems off manually, helping maintain compliance with COSHH regulations and HSE requirements.

Our BOHS-qualified engineers and designers carry out detailed site surveys to assess existing LEV systems, identify opportunities for electrical interfacing, and design bespoke solutions tailored to each client’s operational requirements. We provide complete installation, commissioning, and ongoing support services for a wide range of dust, fume, and oil mist extraction systems across industries including manufacturing, aerospace, automotive, composites, engineering, and education.

At McCarthy Environmental Ltd, we combine technical expertise, industry experience, and innovative engineering solutions to help businesses reduce operational costs, improve sustainability, and maintain safe, compliant working environments through intelligent LEV interfacing systems. 

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.
