Centrifugal Fans, Backward Curved, Technical Features Overview

Higher Air Performance with Less Power Consumption

PBM centrifugal fans with backward curved aerodynamic impeller blades designed as freewheels fans that could be installed at any directions by extremely compact size, and optimized output air performance without scroll housing necessary to have. 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. ErP2015 (Energy-related Products) Directive conformity, COMMISSION REGULATION (EU) No 327/2011 of 30 March 2011 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to eco-design requirements for fans driven by motors with an electric input power between 125 W and 500 kW.
