Extraction Systems
Tailored Laboratory Extraction Solutions
Each laboratory has unique requirements when it comes to fume extraction. We take a bespoke approach, considering:
- The type of chemicals and substances being used
- The required airflow capacity to ensure optimal containment
- Ducting layouts that minimise resistance and improve efficiency
- Integration with existing ventilation systems where necessary
Whether you need a new installation, an upgrade, or maintenance on an existing system, we provide a complete solution tailored to your facility’s needs.

DW154-Compliant Installation
We strictly follow DW154, the UK standard for the fabrication and installation of plastic ductwork systems. This ensures our systems are built using high-quality materials such as PVC and polypropylene, with GRP reinforcement where necessary.
Our Experience
With over 25 years of experience in the industry we have a deep understanding of laboratory safety, airflow dynamics, and system optimisation, we help you create safer working environments while maximising performance and energy efficiency. Whether you’re a school, university, research facility, or industrial lab, our proven track record guarantees a solution that is both effective and future-proof.
Premium-Quality Fans
We exclusively install Colasit and Axair fans, both of which are industry leaders in laboratory extraction technology.
Understanding DW154: Why Compliance Matters
We ensure that all our extraction system installations strictly adhere to DW154, the UK’s recognised standard for the fabrication and installation of plastic ductwork in fume extraction systems. This standard is critical in ensuring that ducted extraction systems are safe, durable, and effective in handling hazardous fumes, gases, and vapours commonly found in laboratories, research facilities, and industrial settings.
What is DW154?
DW154 is the Building Engineering Services Association (BESA) specification that defines the design, materials, and installation standards for plastic ductwork systems. Unlike standard metal ducting, plastic ductwork is essential in environments where chemical resistance and corrosion prevention are required.
Key points from the standard:
- Material Requirements – Only high-performance PVC, polypropylene (PP), or glass-reinforced plastic (GRP) can be used, ensuring resistance to chemical attack.
- Fabrication Standards – Ductwork must be precision-manufactured with sealed joints to prevent leaks and maintain airflow efficiency.
- Installation Best Practices – Proper bracketing, support, and sealing methods must be used to ensure long-term reliability and compliance with safety regulations.
- Testing & Quality Assurance – Systems must be leak-tested and verified for airflow performance before being commissioned for use.
Why is DW154 Compliance Important?
Laboratories and industrial facilities handle hazardous substances that, if not properly extracted, can pose serious health and safety risks. A non-compliant extraction system could lead to:
- Corrosion and System Failures – Poor-quality materials degrade over time, leading to costly repairs and safety hazards.
- Reduced Airflow Efficiency – Ineffective ducting design can result in poor fume containment, increasing exposure risks.
- Legal & Regulatory Issues – Failure to meet health and safety standards could result in non-compliance with HSE (Health & Safety Executive) regulations.
By choosing ILS, you ensure your extraction system is built to DW154 standards.
- Maximum Safety – Protecting staff, students, and researchers from harmful airborne substances.
- Longevity & Durability – Systems designed for long-term performance without frequent maintenance issues.
- Regulatory Compliance – Meeting UK safety regulations and preventing future liabilities.
Our team has extensive experience in DW154-compliant installations, ensuring that every system we design and install meets or exceeds the required standards. If you’re investing in an extraction system, choosing a DW154-compliant solution is the best way to guarantee safety, efficiency, and long-term performance.
