Microbiological and PVT Testing

Our​ Microbiological and PVT (Preferred Vacuum Testing) service is designed to ensure that ventilation systems meet strict cleanliness and safety standards.​

What is Microbiological Testing?

Microbiological testing involves analysing ventilation systems for microbial contaminants such as bacteria and mould. This process is crucial for identifying potential health hazards that can compromise indoor air quality and pose risks to occupants. By conducting thorough microbiological tests, Enviroduct can help businesses maintain a hygienic environment whilst safeguarding the well-being of staff and other occupants.

What is Preferred Vacuum Testing (PVT)?

PVT is a method used to evaluate the cleanliness of ventilation ductwork. The procedure entails vacuuming a specified area within the ductwork and analysing the collected debris to assess contamination levels. This objective measurement assists in determining whether deep cleaning is necessary.

FAQs

Testing helps identify potential health risks and ensures compliance with hygiene regulations, especially in food production, healthcare and commercial environments.

If unsafe levels of microbes are picked up, next steps would include carrying out a deep clean, disinfection and maintenance may be recommended.

PVT provides an objective measurement of duct cleanliness, ensuring compliance with industry standards like TR19. It also helps determine if a full deep clean is required.

Mould spores, bacteria, fungi and allergens are commonly detected in these systems.

The frequency depends on the environment and industry regulations. High-risk areas such as kitchens, hospitals and heavily occupied buildings should be tested more frequently. Speak to a member of our team today for the best advice.
