Explosion-proof drum fans are generally categorized into two types: one with both the casing and the impeller made of aluminum alloy and powered by explosion-proof motors; and another where the casing is made of iron sheet or stainless steel with an aluminum alloy impeller, also powered by explosion-proof motors. The use of aluminum alloy in friction areas prevents ignition, fulfilling explosion-proof requirements.
Ilaharna, explosion-proof motors like BT4 and CT4 are used, with customization options available for high-temperature resistance, lalawanan korosi, and variable frequency. These drum fans are ideal for flammable and explosive environments, sapertos gas alam angkutan.
