Your LEV Design, Installation & Compliance Partner
At Impact Air Systems, we provide a full range of Local Exhaust Ventilation (LEV) services to help businesses across manufacturing, recycling, and industrial sectors protect their workforce and remain compliant with health and safety legislation. From initial system design and installation through to testing, maintenance, and ongoing compliance support, we deliver complete, expert-led solutions—backed by our specialist sister company, Impact Technical Services.
Whether you’re fitting a brand new LEV system or upgrading an underperforming one, we don’t just supply equipment—we engineer peace of mind.
Why Proper LEV Design Matters
The effectiveness of any LEV system begins—and ends—with the quality of its design. A poorly designed system will fail to capture and remove hazardous airborne contaminants, putting your workforce at risk and exposing your business to costly non-compliance.
With over 35 years of experience in air systems design, our team ensures that every LEV system we build is purpose-built, regulation-ready, and proven to perform in real-world conditions. Our engineers are certified to BOHS P602 (Basic Design Principles of LEV)—a UK industry standard for safe, effective ventilation system design.
Tailored to Your Hazard, Built Around Your Process
Every contaminant is different—so your LEV solution should be too. Whether you’re dealing with dust, fumes, vapours, smoke, mist or fine particulate, our LEV specialists will assess your work environment, identify the hazards, and design a solution that effectively captures and removes contaminants at the source—before they reach your workers’ breathing space.
Using HSE-approved best practices, our design process carefully considers:
- Hoods and enclosures to contain contaminants right at the source
- Ductwork to transport pollutants safely away from the workspace
- Filtration and air cleaning units to ensure only clean air is returned or exhausted
- High-efficiency fans to deliver the optimal airflow for consistent, reliable operation
Seamless Installation & Professional Commissioning
We carry out turnkey LEV system installations with minimal disruption to your operations. Our project managers work closely with your team to ensure smooth integration with your workflow, machinery, and schedules.
Once installed, we provide a full HSE-compliant commissioning package, including:
- Full system diagram and user instructions
- LEV logbook for testing and maintenance records
- Commissioning report with key performance data (airflows, duct velocities, pressure drops, etc.)
- Optional airflow indicator for visual performance checks
- Spare parts list (e.g. filter bags, fans, ducting) with full access to replacements via Impact Technical Services
Stay Compliant & Operational with Ongoing Support
LEV systems are only effective if they’re regularly checked and maintained. UK law (under HSE regulations) requires a Thorough Examination and Test (TExT) at least once every 14 months—and more frequently in high-risk environments.
With our ongoing support, we’ll help you:
- Monitor system performance with airflow checks and filter inspections
- Quickly identify and repair damage to fans, ducting, or filters
- Plan proactive maintenance based on system usage and performance trends
- Ensure HSE compliance through scheduled TExTs, documentation updates, and reporting
Our expert technicians at Impact Technical Services handle all testing, monitoring, and servicing to ensure your LEV system continues to meet legal and performance standards.
Protect Your People, Improve Productivity, and Stay Compliant
An effective LEV system not only protects your workforce—it boosts morale, reduces absenteeism, enhances productivity, and demonstrates your commitment to a safe working environment.
Let Impact Air Systems design a tailored, future-proof LEV solution for your facility, backed by industry-leading technical support and regulatory knowledge.
