Frequently Asked Questions:
How do I know if I need an LEV system?
If your workplace generates dust, fumes, vapours, smoke, mist or airborne particles that could affect employee health, an LEV system may be required to control exposure.
Can you design a system for an existing workshop?
Yes. We regularly design new extraction systems for existing buildings and can also upgrade or modify older LEV installations.
Do you install the systems you design?
Yes. We provide a complete turnkey service, including design, supply, installation, commissioning, testing and ongoing maintenance.
Will the system comply with COSHH?
Every system is designed to help businesses meet their legal duties under COSHH and current HSE guidance. We also provide Thorough Examination and Test (TExT) services to help ensure continued compliance.
Can you upgrade an existing LEV system?
Absolutely. Many businesses have systems that no longer meet current operational needs. We can assess your existing installation and recommend improvements to increase performance, efficiency and compliance.

What is LEV Design?
LEV (Local Exhaust Ventilation) is an engineering control system designed to capture airborne contaminants at source before they enter the workplace atmosphere.
A properly designed system will:
-
Capture contaminants as close to the source as possible
-
Transport contaminated air safely through ductwork
-
Remove harmful particles using suitable filtration
-
Discharge clean air safely where appropriate
-
Maintain consistent airflow and extraction performance
-
Operate efficiently with minimal energy consumption
Good system design is critical to ensuring long-term performance, reliability and compliance.
Our LEV Design Process
Every project begins with a detailed assessment of your workplace.
Our design process includes:
Site Survey
Our engineers visit your premises to understand your manufacturing processes, identify airborne hazards and assess the most effective extraction methods.
Risk Assessment
We identify the substances being generated, how employees are exposed, and the most suitable engineering controls required to reduce exposure.
System Design
Using the information gathered during the survey, we design a bespoke LEV system that considers:
-
Type of contaminant
-
Capture method
-
Airflow requirements
-
Duct sizing
-
Fan selection
-
Filtration requirements
-
Future expansion
-
Energy efficiency
-
Ease of maintenance
Installation & Commissioning
Once approved, our experienced engineers install and commission the system to ensure it performs as designed.

Why Good LEV Design Matters
A correctly designed LEV system can help your business:
-
Improve workplace air quality
-
Reduce employee exposure to hazardous substances
-
Meet COSHH requirements
-
Improve production efficiency
-
Reduce housekeeping costs
-
Protect machinery from dust contamination
-
Improve energy efficiency
-
Reduce maintenance costs
-
Extend equipment lifespan
-
Improve overall workplace safety
Investing in good design at the beginning often reduces operating costs for many years to come.
Helping You Meet COSHH Requirements
Employers have a legal responsibility under the Control of Substances Hazardous to Health (COSHH) Regulations to adequately control exposure to hazardous airborne contaminants.
Our qualified P601 and P602 engineers design systems in accordance with current guidance, including:
-
COSHH Regulations
-
HSG258 – Controlling Airborne Contaminants at Work
-
Industry best practice
We design systems that are not only effective on day one but remain practical to maintain and test throughout their operational life.
