Overview

About the service.

Hazardous dust and process debris gradually build up inside LEV systems, reducing extraction performance and increasing the risk of worker exposure to airborne contaminants. Without regular cleaning, systems become less effective at controlling dust at source.

Our engineers professionally clean LEV systems to restore internal cleanliness and maintain reliable extraction performance. Every project is supported by detailed reporting, photographic evidence and clear documentation for a fully auditable record.

What’s included

  • Internal LEV ductwork cleaning
  • Hood, booth & extraction point cleaning
  • Fan & filter chamber cleaning
  • Dust collection unit cleaning
  • Photographic reporting & certification

The hidden risks

Contamination affects protection.

Hazardous dust and process debris gradually build up inside LEV systems, reducing extraction performance and affecting the system’s ability to capture contaminants at source. Left untreated, contamination can compromise both system efficiency and workplace safety.

Routine cleaning removes these hidden deposits, helping maintain reliable extraction performance, protect equipment and support a safer working environment.

What builds up in your ductwork

Why it matters

Protecting your LEV system.

Regular LEV system cleaning helps maintain extraction performance, protect employees from airborne contaminants and support the safe, reliable operation of your ventilation system

Improved extraction

Removing combustible lint and fibre deposits significantly reduces the risk of fire within the extract system.

Workplace safety

Clean LEV systems help reduce employee exposure to hazardous airborne dust and contaminants.

Equipment protection

Reducing contamination helps minimise wear on fans, filters and system components, extending equipment life.

Compliance support

Routine cleaning supports ongoing LEV maintenance and provides documented evidence of system hygiene and condition.

Our Approach

Cleaned with precision.

Every LEV system is assessed before work begins to identify the type of contamination, system layout and access requirements. This allows our engineers to select the safest and most effective cleaning method for each installation.

Using specialist equipment and controlled working practices, we clean the complete LEV system with minimal disruption to your operations. Every project is supported by detailed inspections, before-and-after photography and comprehensive reporting, providing a clear record of the work completed.

How it works

From survey to certificate.

A clear, accountable process — documented at every step.

01

Survey

We assess the LEV system, identify the type of contamination and agree the safest cleaning method before work begins.

02

Access

Access panels are installed where required, allowing all sections of the system to be safely inspected and cleaned.

03

Clean

Ductwork, branches, fans and associated components are cleaned using specialist equipment to remove hazardous dust and process contamination.

04

Report

A comprehensive photographic report is provided, documenting the work completed along with recommendations for any remedial actions.

FAQs

Common questions.

How often should an LEV system be cleaned?

Cleaning depends on the process and contaminant levels. Regular inspections help determine when cleaning is required.

Why does an LEV system need cleaning?

Hazardous dust build-up reduces extraction performance and can affect workplace safety.

Will LEV system cleaning disrupt our operations?

We plan every project to minimise downtime and work around your operational requirements where possible.

What do I receive after the cleaning is complete?

A detailed report with before-and-after photographs and recommendations where required.
