Radial type smoke pump VD

VD blower fans are produced in the form of a monoblock. On a single support frame, which is a welded metal structure, there is an electric drive connected to a centrifugal fan. Air suction occurs along the axis of the fan impeller, and ejection - through the volute at an angle of 90 degrees to the axis.Blow fans series VD are produced with a rotating volute, which makes it possible to direct the outlet pipe at an angle of 0 to 270 degrees (rotation step - 15 degrees). On the outlet spigot of the volute there is a rectangular flange with holes for connection of the equipment with ventilation system ducts.Installation of VD smoke pumps is carried out on the foundation or ceiling of the building. The support frame has holes for anchoring. To reduce the level of vibration and noise, it is recommended to use vibration-isolating spacers between the frame and the surface of the support.According to the execution of UA are divided into right and left.
