SWF-I / II

SWF Mixed-Flow Fan

Meridional-acceleration design that can replace a low-pressure centrifugal fan.

Conical collector, twisted blades and a meridional acceleration path raise pressure while cutting A-weighted noise by 2–3 dB compared with an equivalent axial fan. Often specified as a drop-in replacement for low-pressure centrifugal units.

Specification

DesignMeridional acceleration, conical hub and twisted aerofoil blades
CasingSteel, hydraulically formed blades, spun flanges, balanced to ≤ G5.6
SpeedType I single · Type II dual speed · VFD
OptionsEXdIIBT4 explosion-proof, acoustic pod
Temperature−20 to +40 °C standard

Design notes

  • 2–3 dB(A) quieterMeridional acceleration reduces turbulence at the blade tip.
  • Higher pressure, smaller boxDelivers centrifugal-class pressure in an axial envelope.
  • Direct replacementFlange dimensions match common low-pressure centrifugal fans.

Options

  • Dual speed
  • Explosion-proof
  • Acoustic enclosure
  • Silencer

Applications

  • Commercial HVAC
  • Car parks
