Inline Centrifugal Fan with DWDI-YFICK

Inline Centrifugal Fan with DWDI-YFICK

Volume range:1,400~115,000 m³/h

Static pressure range:100~1,800 Pa

Impeller Specification: 280~1,000

drive type: Belt Driven

Installation: hanging, floor-mounted

Wheel feature

  • The forward inclined DWDI wheel has good ability of low noise and reliable running
    • The forward curved wheel has bigger volume comparing with backward curved wheel in the same speed
    • The forward curved wheel has lower speed and lower noise comparing with backward curved wheel in the same working condition.
    • Spinning precisely matched Venturi inlets and wheel cones assuring smooth, which further results well rectification effect and low noise
  • Advanced technology ensure accuracy
    • The fan housing is “Pittsburgh” method joined, which results 0 air leakage
    • The two pieces of housing side joint at the same one time procedure to improve the accuracy and reduce the dimension of assembly error
    • The blades are made by once punch forming, and dedicated fixture to ensure precise install
  • More reliable physical design
    • The forward curved wheel precisely designed reinforcing threaded rod make sure long time reliable running
    • The backward curved wheel reinforcing rod set on exact position to ensure long-term secure operation
    • The fan is supported by stable channel steel frame, so that stable running of the fan is ensured
  • The backward inclined DWDI wheel has good ability of high efficiency and high energy savings
    • The backward curved wheel has higher efficiency comparing with axial wheel, mixed flow wheel and forward curved wheel
    • Accurately sized V-type performance baffle effectively reduced turbulence which results low noise and high efficiency
    • The backward curved wheel has repeatedly optimized performance cures results safer running
  • High balancing level
    • Balance level up to G2.5 (Typical products are balanced to G6.3 only)
    • To reduce the vibration of the fan, to improve reliability
    • To reduce the running noise effectively

Product feature
