Why Should we clean ductwork?
Ductwork in all shapes and sizes is used to ventilate and condition numerous types of premises such as hospitals, offices, cinemas, kitchens and museums. Almost always the ductwork is hidden from view and the accumulation of debris is not apparent. If left this debris may propagate unwanted allergens or provide a breeding/feeding ground for insects and vermin. This can seriously effect staff productivity and pose a health risk to visitors and customers.
To address these problems access must be gained to the system. Even though current ductwork specifications, DW 144, call for access doors at pre-determined locations and distances it is likely that additional doors will be required to clean the ductwork to H.V.C.A. TR19, HTM03-1 & C.I.B.S.E. TM26 standards. Once access is gained a variety of techniques can be used to dislodge debris from the internal surfaces of the ductwork prior to vacuum removal. Most common, in ductwork up to 800mm diameter, is the rotary brush system, which can be worked at long distances and orientated around bends. This reduces access door requirements to a minimum.
We can provide quotes for any given project by way of a site survey. Alternatively drawings can be sent by post or email so that a linear meterage can be established. Our “in house” plotting capability of emailed drawings helps speed up the quotation process for those requiring an urgent price.
