What the listed services involve

Ductwork

Ducts carry contaminated air from the capture point towards a collector or discharge point. Work on their layout, joints and condition affects airflow, access for cleaning and the build-up of material inside.

LEV installation

Installation involves fitting the extraction equipment and connecting it to the machines or work areas it serves. Commissioning checks its performance under working conditions and establishes measurements for comparison at later tests.

LEV repair

Repair work addresses faults such as damaged hoods, leaking connections or failed fans. Checking performance after the repair helps establish whether the system controls exposure again.

LEV servicing

Servicing involves maintaining components such as fans, filters and moving parts so the extraction system can keep working as intended. It can help address wear or blockages between thorough examinations and tests.

LEV testing

A thorough examination and test checks the condition of your extraction system and measures airflow to assess how it controls exposure. For most LEV, this is required at least every 14 months under regulation 9 of the Control of Substances Hazardous to Health Regulations 2002.
