Axair Fans is offering special designs of frame axial fan for continuous operation in demanding environments. Where heat transients or mechanical impact can be a hazard to plastic impeller fans, external rotor motor products can be provided with ‘all metal’ impeller. For elevated and sustained temperatures up to 90ºC these fans can also be supplied with heat resistant components. Ingress protection to IP25 or IP55 is available. Axair can also customise the fan installation by offering stock accessories such as power leads, finger guards, elastic rivets, and air filters.
