Backward Curved Centrifugal Fan Manufacturer

EC Fans'Technical Features Overview

PBM series EC (Electronically Commuted) Fans combine interactively external motor technology, integrated electronic control circuit and aerodynamic design of fan impeller that satisfied customers' requirements in different applications and industries by innovative air-moving solutions. We are pursuing Ultra-low Energy Consumption fans by extremely compact brushless permanent magnet synchronous external rotor motor to drive various of aerodynamic optimized impeller and scroll-housing types and sizes: diagonal axial, backward and forward curved centrifugal, radial, single inlet and dual inlet blower, tangential, cross flow.

Impeller Sizes:From minimum 30mm to 560mm diameter;

Sound Level:From 31dB(A) to maximum 82dB(A) according different rotation speed;

Airflow:Maximum to 16,300CMH, Cubic Meter per Hour, equal to approx. 9,593CFM , Cubic Feet per Minute;

Air Pressure:Maxim to 1,700Pa, equal to 173.5mm H₂O and to 6.82 inches H₂O;

Power:Maximum motor input power goes to 3.1KW (equal to 4.2hp, horsepower) at motor diameter 138mm.
