Ventilation systems are designed to ensure that the quality of the air in a building is as good and free from contamination as possible for its users.
They can be installed to deal with a particular type of activity, for example the LEV systems that are used in many manufacturing and laboratory settings to extract harmful chemicals and particles given off by particular processes in the work area. Examples of this would be the fine dusts and sawdust given off when wood is being machine or hand cut.
In a commercial kitchen ventilation ducts are part of the extraction system, usually leading from hoods and filters above cooking ranges to extract dissolved grease and food particles in steam given off by cooking.
Where they have not been installed to deal with the specific processes illustrated in these examples their main purpose is to ensure adequate, clean and breathable air in such buildings as offices, colleges, schools or residential homes.
A ventilation system’s efficiency depends heavily on how clean its interior ductwork and the filters are. The system may also be connected to an Air Handling Unit, a machine that is used in connection with some air conditioning and central heating systems.
The most important point with any ventilation system is that it needs to be properly maintained and regularly cleaned if it is to work efficiently to keep energy bills to a minimum and ensure the atmosphere in which people are living or working is providing adequate clean and breathable air.
If the system does not work as designed there is the risk that dust that has been allowed to build up inside the ductwork can become the perfect environment for bacteria and fungi to breed. The same applies to blocked or heavily contaminated filters.
Left unchecked this could eventually lead to various illnesses affecting people in the building, generally showing as mucous membrane inflammation, migraine, tiredness and even depression. In the work setting this can lead to lost productivity, an additional cost on a business.
Maintaining an efficient ventilation system requires regular air duct cleaning. A schedule of checking, cleaning and replacing filters is also part of a thorough duct cleaning regime.
The B & ES, (the new name for the HVCA) has published recommendations for four step maintenance programme for ventilation system efficiency, which includes checking for are any contaminates affecting the system, pinpointing its source and removing it and introducing a proper routine of filter changing and ductwork cleaning to keep the ventilation system running properly.
This is no job for an amateur. It requires comprehensive knowledge of the system, the best cleaning products if needed and proper equipment to do a thorough job. A specialist professional duct cleaning company will be able to determine where there are problems in the system and should be equipped with the high-powered vacuum suction devices that can effectively remove all traces of contamination.
Energy costs and productivity can suffer if a building’s ventilation system is not working effectively and in need of ductwork cleaning. By Ali Withers.
