Hvorfor eksplosjonssikre fans er eksplosjonssikre

Det primære formålet med eksplosjonssikre vifter er ikke å forhindre at selve viften eksploderer, men heller for å avverge støveksplosjoner i produksjonsmiljøet. I enkelte bransjer, prosesser genererer brennbart og eksplosivt støv, som metall- eller kullstøv. To prevent these kinds of dust from becoming airborne during production, exhaust systems are commonly used for suction and collection.

During this process, friction or sparks in the fan could be extremely hazardous. Derfor, the necessity for explosion-proof fans, which are specially designed and made from materials different from standard fans.

1. Explosion-proof fans are equipped with aluminum impellers, primarily to prevent sparks generated by friction between the impeller and the fan casing.

2. These fans must be powered by explosion-proof motors to ensure safe operation in potentially hazardous environments.
