EC Centrifugal Fans With Backward Curved Blades For Intake Suction Low Noise

  • EC Centrifugal Fans With Backward Curved Blades For Intake Suction Low Noise
  • EC Centrifugal Fans With Backward Curved Blades For Intake Suction Low Noise
  • EC Centrifugal Fans With Backward Curved Blades For Intake Suction Low Noise
  • EC Centrifugal Fans With Backward Curved Blades For Intake Suction Low Noise
Product Details:
  • Noise-optimized air outlet in scroll housing.
  • Pressure-optimized blower
  • shaded pole motor
  • Impedance protected.

ec centrifugal fans with backward-curved blades are used primarily for intake suction. Since most of the pressure build-up takes place in the impeller, there is generally no need for a scroll housing. The centrifugal fans have very good hydraulic efficiency and are ideally suited for high pressures. The centrifugal fans are used in applications such as central air conditioning units or building ventilation systems.

Features:

  • Size: 133mm diameter X 90mm
  • Material: spiral housing of fiberglass-reinforced plastic scroll housing base of aluminum sheet.
  • Fully integrated electronic commutation.
  • Protect against reverse polarity and locking.
  • Direction of air flow: axial air intake, centrifugal air exhaust out of the outlet.

Key Specifications/Special Features:

Type LD133C-230D3-00
Nominal voltage 230VAC
Speed 4500RPM
Power input 53W
Current draw 0.43A
Air Flow 380m³/h
Sound pressure level 68dB
