Vibration induced noise can be a major problem in fan coil installations. It originates within the motorised impeller unit and cannot be entirely eliminated until new technology invents an induction motor that is free of electromagnetic vibration and an impeller that is perfectly balanced. Ecofit believe they have gone a long way towards solving the problem by introducing double inlet centrifugal fans that incorporate anti-vibration mountings between the fixed shaft and the scroll mounting arms. The fans, prefixed ‘GDS’, therefore achiev...
The air handling unit market is under constant pressure from all sides; pressure from the end user to improve indoor air quality, pressure from architects to provide more comfort and to produce more aesthetically pleasing units but also from energy consultants who demand manufacturers to deliver energy efficient units with higher airflow performance and pressures at lower installation and operating costs. Commercial heating and ventilating represent a major proportion of any construction budget, frequently comprising ten percent or more of t...
Axair’s Labair controls range has been created for applications involving hazardous fume extraction such as fume cupboards and chemical cabinets. There are two models available A and C, both of which are available in a standard version or Digital. Both the A and C series are white with 3 push buttons: fan on/off, light on/off and alarm mute. They also feature a green LED light that illuminates to signify that the airflow is OK, a red LED light that flashes to alert that the air speed is too low and a sash high LED which starts flashing whe...
Offshore oil and gas platforms incorporate a wide range of fan applications from production areas, power generation and compressor cooling. Offshore sites are built to withstand the harsh and corrosive environments in which they’re situated, and therefore components within systems must be suitable for purpose. Where hazardous gases are present, ATEX variants are required and should be specified by the system manufacturer’s maintenance manuals to advise the zone that the components should be certified to. Corrosion resistant fans that are op...
