Ny fepetra “tsy mipoaka” ho an'ny mpankafy amponga dia manondro ny famolavolana azy ireo izay manasaraka ireo singa elektrika afaka miteraka pitik'afo, arcs, ary ny maripana mampidi-doza avy amin'ny fangaro entona mipoaka manodidina mandritra ny fandidiana. Ity famolavolana ity koa dia miantoka fa tsy misy pitik'afo mamokatra rehefa misy toe-javatra manokana miteraka fikomiana amin'ny casing mpankafy, thus maintaining safe production practices.
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.
matetika, explosion-proof motors like BT4 and CT4 are used, with customization options available for high-temperature resistance, fanoherana ny harafesina, and variable frequency. These drum fans are ideal for flammable and explosive environments, toy ny entona voajanahary FITATERANA.
