For higher-duty cycles such as continuous broadcast or increased ambient temperature, additional fan use is recommended. The auxiliary fan is brushless type, 2...5 W, 24 VDC, size 92x92 mm. It may be installed by your dealer or by the manufacturer on request. ACOM recommends a fan ordering, if you need it, with the purchase of a new amp.
