The SA-TE range are roof mounted axial vertical supply fans, designed to supply ventilation to environments that require fresh air to replace polluted to unsatisfactory air that has been removed by an exhaust fan. As a vertical discharge axial fan, the SA-TE range is able to cater to higher pressures and potentially noxious gases, while still maintaining the benefit of a smaller, lighter, more cost-effective unit. The SA-TE range incorporates high-efficiency, corrosion resistant rotor-motor impellers in single or three phase. The impellers are formed from fibreglass reinforced polypropylene, while the body is constructed from durable galvanised steel. It is therefore well-suited to supplying air for building ventilation in industrial contexts.
