To expand the performance range of this series of fans and meet the needs of various large, medium, and small non-coal mines, a wide range of ventilation networks with low, medium, and high resistance, as well as large, medium, and small air volumes, can now select main fans, auxiliary fans, and multi-stage station fans that operate in the high-efficiency zone. This series of fans employs multiple hub ratios and two structural types: single machine and counter-rotating, which are categorized into six types: FKZ, FBCDZ (K40, K45, and DK40, DK45, DK62, DK54). The FKZ (K40) is available with 4, 6, and 8-pole motors for three speeds, the FKZ (K45) with 4 and 6-pole motors for two speeds, and the FBCDZ (DK40DK45, DK62, DK54) all with 6 and 8-pole motors for four speeds.
