The subway and tunnel are tens of meters under the ground surface, which cannot completely rely on natural ventilation. Therefore, it is necessary to install tunnel fans to deliver and regulate the air or exhaust the smoke and dust. Axial fan is the common use type.
Axial fan with adjustable blades is generally used to hang on the roof of the subway or tunnels because the concentration of dust in subway and tunnels can be operated automatically.
The impeller is made of cast aluminum hub and adjustable airfoil blade, which makes the fan high efficiency. The fan can work continuously 2 hours at 400℃. The ADF series fan is widely used in commercial areas, such as hospitals, hotels, schools and shopping malls.
The fan is molding design based on the axial fan, which is generally hung on the top or at the sides of the tunnel. The numbers of the fan and the how many of them can be arranged side by side can be designed depends on the length of the tunnel and the size of the tunnel section. The SDS series fan is widely used in the longitudinal ventilation system of highway and railway tunnel.
The fan consists of impeller, motor, casing, guide vane unit, support etc. The blade can be both rotary and stationary. The blade angel can be adjusted by pneumatic or electric control. High efficiency, low noise and good strength. The DTF series fan is widely used in metro, tunnel, electricity power plant, construction engineering projects and the place where need fire smoke emission.
Belt driven centrifugal fan with double inlet. Various of outlet directions are available. Floor mounted or over hanging installation are both fine. CKS series fan is widely used for fire smoke exhaust and kitchen smoke exhaust.
The housing material is environmental, fire prevention, waterproof, corrosive and rust free, which complies with the requirements of the fire safety rules.
