The FBD coal mine-specific local ventilator features a rational structure, complete specifications, high efficiency, significant energy-saving effects, low noise, and long air delivery distance. It can be used either as a whole unit or in stages, depending on the requirements of different ventilation resistances, thereby reducing ventilation time and conserving energy. For tunnel lengths of 2000m or less, the ventilator can deliver air without movement, reducing the labor intensity of workers, saving ventilation time, and is an ideal equipment for local ventilation in coal mine shafts. Additionally, it is also suitable for high-pressure ventilation scenarios in metallurgy, non-ferrous metals, tunnels, gold mining, chemicals, shipbuilding, and ceramics industries.

Features of coal mine special-purpose local ventilator:

The FBD series fans feature gentle air pressure and minimal surge, operate stably in high-pressure, low-flow areas, have long ventilation distances in underground mines, and are highly adaptable to complex tunnels.

The FBD series ventilators, to enhance the corrosion and wear resistance of the blades and the body, employ thermal spraying technology in the manufacturing process. Based on the corrosive elements found in mine environments, over 20 different materials are formulated. Using supersonic arc spraying and high-speed flame spraying, the body and blades are heat-sprayed, ensuring the blades remain rust-free, wear-resistant, and corrosion-resistant, with a long service life.
