In response to the ongoing coronavirus pandemic, there is increased demand for ventilation systems to be assessed and, where necessary, cleaned. To assist technicians, the National Association of Air Duct Specialists UK (NAADUK) has now issued cleaning guidance for ductwork fabricated from the Kingspan KoolDuct System.
NAADUK carried out up to 100 tests on different sections of Kingspan KoolDuct including 90-degree angles and t-sections. They determined that they can be cleaned by a competent technician using a mechanical rotary brush with plastic fibres (polypropylene is recommended) at a speed of up to 900RPM. It is also recommended that a plastic ball is fitted to the end of the metal shaft. Where required, access doors can easily be added to existing Kingspan KoolDuct sections to aid cleaning and inspection.
By following this advice, NAADUK say that Kingspan KoolDuct ductwork can be cleaned in accordance with the requirements of BS EN 15780 for the lifetime of the ductwork.
