Swimming Pool Extraction Fans: Corrosion Resistance

Chlorine is widely used to treat water for swimming pools in leisure centres and domestic pools. When extracting chlorine fumes from areas such as plant rooms and storage cupboards after dosing, the air may be corrosive. If this is the case, it will need to be extracted via a polypropylene fan and plastic ductwork as metal systems would corrode over time. ATEX Requirements Chlorine has the potential to become explosive when mixed with certain other chemicals. Therefore, the swimming pool extraction system may need to be ATEX (Atmospheres Expl...


Medium Pressure Centrifugal Fans: Backward Curved Benefits

What is a backward curved centrifugal fan? The backward curved centrifugal fan design uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. The assembly of the hub, disk and blades is known as the fan wheel, and often includes other components with aerodynamic or structural functions. The centrifugal fan wheel is typically contained within a scroll-shaped fan housing. How does a backward curved centrifugal fan work? Backward cu...


Shipyard LEV Systems

Local Exhaust Ventilation, or LEV, is a recommended method of shipyard ventilation. The nature of the shipbuilding industry means that air quality can be poor due to the presence hazardous chemicals, dust and welding fumes. To ensure workers are not exposed to these potentially harmful substances in often confined working spaces, LEV systems are key. LEV involves trapping airborne contaminants at their source before they pollute the air that is breathed by workers. For welding, cutting and heating processes, this type of ventilation must con...
