Bespoke Fume Extraction Hoods
Bespoke extraction canopies are tailor-made to your exact needs and requirements and are matched with the air flows required to ensure that your business complies with HSE’s 'HSG258: Controlling Airborne Contaminants at Work: A Guide to Local Exhaust Ventilation (LEV)' regulations and COSHH (Control of Substances Hazardous to Health) 2002 regulations.
Fume extraction canopies have a broad range of applications and can be manufactured out of stainless steel, galvanised steel, polypropylene, PVC or polycarbonate sheet. Extraction canopy hoods for laboratories can be specified too as they are custom-sized to your extract requirements to safely remove the heat of fume out of the workplace.
How do Fume Extraction Hoods Work?
Fume extraction hoods are ideal for processes where contaminants naturally arise, for example, welding fumes, hydrogen from battery charging processes, steam production, heat removal from food manufacturing processes and many more.
Canopy fume hoods draw fumes inwards and up the canopy and through the extraction system. However, depending on the processes being employed and whether or not the contaminants are passing the worker's breathing zone, an articulated extraction arm may be required. The entrance of the canopies will draw in any residual fume at the extractor hood.
What do the HSE State?
HSE HSG258: Controlling Airborne Contaminants at Work: A Guide to Local Exhaust Ventilation (LEV) advises that: “Receiving canopy fume extraction hoods should be placed as low and close as possible to the process as practically possible so that the risk of rising fumes dispersing out into the workplace or being affected by through-draughts is reduced.”
Whilst the University of Birmingham describes the receiving capture canopy fume hood as: “The process where the working process provides the energy to deliver the fumes and gases to the canopy hood” (Local Exhaust Ventilation Systems, 2012).
What Materials Are Used to Make Canopy Hoods?
Fume extraction hoods can be made from a wide range of materials. Stainless steel is perhaps the most common choice, but other materials can also include polypropylene, PVC and galvanised steel. The best type of material will depend on the purpose of the canopy hood and the environment in which it will be installed. Typically, hoods should be compatible with the type of chemicals that you intend to capture. Factors to consider include how durable the hood is and whether it is resistant to certain acids and other chemicals. You may also need to consider whether it is resistant to fire, smoke and corrosion. Finally, don't forget to take into account how easy it is to clean and maintain the canopy fume hood.
