- Each system was successfully cleaned by installing access doors and vaccuming the internal surfaces of the ductwork and associated plant.
- On completion dust deposit levels were less than 0.8 microns in accordance with TR19.
- It is always recommended that continued cleaning and monitoring every 3-5 years and that intake/supply air filters are replaced frequently in-line with manufacturers guidelines. This will help to ensure the ductwork remains clean and free from anything that may contaminate the air or encourage microbiological growth. On this occasion we also recommended annual assessments of the supply and extract systems by means of vacuum testing and microbiological sampling. These should be conducted and compared against the industry guidelines and parameters set out in BESA TR19 & CIBSE TM26.
