Centrifugal Fans Forward Curved

Centrifugal Fans, Forward Curved，Technical Features Overview

Higher Air Pressure with Lower Noise and Power Consumption

Blauberg centrifugal fans with forward curved impeller designed as freewheels fans, with and without scroll housing optional. The fans could be installed at any directions by extremely compact size, and optimized output air performance without scroll housing necessary to lower noise at customer requested higher air pressure output in their ventilation duct system or unit box of different materials, such as galvanized metal, aluminum, copper, PE, PVC, polyfoam etc.  AC and DC power supply are available for entire range of fans with integrated and intelligence EC technology motor with inside or outside mounted international standard remote control R485 communication protocol that’s suitable to be adopted in IoE(Internet of Everything), IoT(Internet of Things), smart home system, Industry 4.0 and committed to Carbon Neutrality climate change by reducing customers carbon footprints. PFC(Power Factor Correction), up to λ>96%,  is optional for electricity grad stabilization compliance in certain circumstances of applications.
