DA-M Range – Roof Mounted Centrifugal Exhaust Fans

Roof mounted exhaust and supply fans are integral to a number of environments, removing industrial fumes and supplying a suitable air flow to maintain a comfortable air pressure. In comparison to centrifugal roof mounted exhaust fans, axial fans produce a larger amount of noise pollution, and are therefore better suited to industrial contexts such as factories rather than domestic environments such as bathrooms and small kitchens. The durable, high efficiency impellers are driven by an external rotor motor with an IP54 rating. This means the motor is capable of protecting against dust and splash water, and can therefore feasibly be used in industrial settings without worry of ingress. The DA-M range is available in 7 different sizes, offering a choice of various pressures and air flows, ensuring suitability for a wide range of situations. Further, there are multiple options of either 4 or 6 motor poles, allowing for variation in the RPM and torque of the system, where motors with a larger number of poles provide more torque at a slower speed. Some models further offer a choice between a single phase and three phase motor, providing the option for a larger amount of power if necessary. These roof mounted axial exhaust fans are enclosed in a durable, UV stabilised, hail proof polymer case. This ensures protection from the unwanted ingress of dust and water. UV stabilisation and hail proofing further ensure resistance to weather, which is of particular importance in the context of roof mounted fans which are exposed to external environments.
