Aluminum explosion-proof fan blades are ingeniously designed to prevent the occurrence of sparks caused by high-speed collisions between the fan impeller and the casing or air intake. Hierdie ontwerp is van kardinale belang om ontploffingsrisiko's te versag.
Vir plekke wat ontploffingsvaste waaiers gebruik, die operasionele vereistes is veral streng. Alle komponente, including the motors, must adhere to explosion-proof standards, negating the possibility of open flames or sparks and thereby averting potential plofstof gevare.
