Professional & Accredited System Cleaning Engineers


Our air handing and local exhaust ventilation (LEV) system cleaning services are proven to significantly improve your air hygiene and minimise the potential for airborne contamination.


Our BESA trained air hygiene engineers provide a professional and reliable cleaning service for your entire air handling system. We will clean your air handling unit from the supply right through to the fresh air intake. Our metal and fabric duct cleaning is carried out to TR19 standards and includes cleaning of the air discharge points and all equipment in line. The service includes full electrical and mechanical checks. Similarly, we will check, test and clean all parts of your dust extraction system to ensure it works as efficiently as possible to remove hazardous substances from your indoor air. 


Recommended Frequency of Cleaning


Air handling units should be cleaned every 6 months at a minimum, in line with the BRCGS Food Safety Issue 8, and LEV systems should undergo a thorough examination and test (TExT) every 14 months by P601 trained engineers, in accordance with HSE recommendations.

How Regular Cleaning Protects Your Brand & Employees


The whole food industry is centered around perishable products that can at some stage be affected negatively by bacteria. Consequently, in the manufacturing and processing of food products airborne particles can be carried to production areas through the air handling system and ductwork, potentially leading to cross contamination. These airborne particles can include product and packaging debris, bacteria and virus particles.


Furthermore, the build-up of dust, dirt and grease in air ducts can result in significant health & safety issues due to potential fire hazards and poor performance of the equipment. Reduced effectiveness of an extraction system, can also impact equipment service life. 


Regular system cleaning, repair and maintenance helps prevent the build-up of dust, product, condensate and pathogens to keep your indoor environment safe - protecting your brand, your process and your profit.
