Extraction / Supply Ducting
Based on recommendations by the HVCA (Heating and Ventilation Contractors Association), full Ventilation System Ducting Deep Cleaning can be carried out in line with the "HVCA TR/19 Guide to good practise: Cleanliness of Ventilation systems".
All systems are cleaned using remote compressed air method technology in conjunction with high volume extract units. These units capture contaminated air and filter it through high efficiency HEPA filters to ensure that no contamination reaches the open air.
For quality control, air particle samples are taken which must achieve a level of no more than 0.075g dust per cubic metre.
