Axial flow fan WL-SIGMA 1000
Axial flow fan WL-SIGMA 1000 is designed for independent/separate ventilation of mining excavations (e.g. in coal mines, cooper mines). Due to its construction, axial flow fan WL-SIGMA 1000 can operate in forcing or exhaust ventilation system.
Axial flow fan WL-SIGMA 1000 can be applied in underground mining methane and non-methane excavations, considered as level “a”, “b” and “c” area exposed to danger of methane explosion, as well as grade “A” and “B” danger of coal dust explosion. Axial flow fan has been classified as Group I, category M2 due to its application in areas exposed to danger of explosion (according to directive 2014/34/UE).
