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. Muundo huu ni muhimu katika kupunguza hatari za mlipuko.
Kwa maeneo yanayotumia feni zisizolipuka, mahitaji ya uendeshaji ni magumu sana. Vipengele vyote, including the motors, must adhere to explosion-proof standards, negating the possibility of open flames or sparks and thereby averting potential kulipuka hatari.
