  A、Application:
  FRP oblique flow fan is widely applied in industry and civil buildings, especially suited to pipe ventilation by boosting pressure.
  B、Types:
  Types include ordinary type, anti-explosion type, anti-corrosive type, roof type, one-way type, noise reduction type and other types used in special environment.
  C、Features:
  1.Its performance is between centrifugal fan and axial flow fan. Its pressure and flow are lower than centrifugal fan and axial flow fan with stable property and low noise.
  2.Its structure is compact with small floor area. It can be connected with hair dryer directly and hoisted making installation easy.
  3.It has many types and each type suits to different environment.
  (1)Ordinary type is applied in the environment with —10℃ to 45℃ temperature, under 90% relative humidity and without inflammable, corrosive gas.
  (2)Anti-explosion type is applied in the environment with inflammable gas, —10℃ to 45℃ temperature, under 90% relative humidity and without highly corrosive gas.
  (3)Anti-corrosive type is applied in the environment with corrosive gas including salt fog or alkali, —10℃ to 45℃ temperature, under 90% relative humidity and without inflammable gas.
  (4)Roof type is applied in roof.
  (5)One-way type is applied in the environment with 220V one-way power supply. According to different environment, it can be divided into one-way anti-explosion type, one-way anti-corrosion type and one-way noise reduction type.
  (6)Noise reduction type is applied in place with strict noise requirement. According to different environment, it can be divided into anti-explosion noise reduction type , one-way noise reduction type and anti-corrsion noise reduction type.
  (7)Special type is designed and manufactured according to the customer’s requirement. We can produce wear-resisting fan, high temperature resistance fan, variable air rate fan.
  D、Installation, use and maintenance:
  1.You should check all parts such as casing, impeller and all joint parts before installation. It there is problem, repair immediately.
  2.Pipe of air inlet and outlet connecting with fan should not supported by casing. Please add other support for the pipe.
  3.Direction of impeller and airflow should be same with scutcheon direction before installation.
  4.Fan pedestal and base plane should be jointed naturally. Don’t beat the pedestal and joint it and base plane forcefully.
  5.Before starting the fan, please make sure there is no obstruction in the fan and pipe.
  6.There is no collision and friction when turning the impeller by hand.
  7.The user should overhaul the fan every half a year. Pay attention to every parts before stating.
  五、Common failure analysis
  1.Abnormal vibration
  (1)When the fan rotating, impellers touches the casing.
  (2)Foundation rigidity is not enough or fan pedestal is not stable.
  (3)Dynamic balance of impeller is damaged.
  (4)Inlet and outlet pipe is not installed well.
  2.Motor current is too large and its temperature increase.
  (1)Motor bearing is damaged.
  (2)Impellers touches the casing.
  (3)Systemic resistance is too large to run for the motor.
  (4)Input voltage of motor is low or the power is off.
