400mm Premium EC Backward Curved Impeller Centrifugal Fan for Heat Exchanger

Product Features

Romulus Series Centrifugal Fan is an ideal solution for the new generation FFUs, ventilation and air conditioning systems, data centers, and other felds. The Romulus backward-inclined centrifugal fan is the latest high-effciency centrifugal fan series introduced by Seemtek. The motor boasts compactness, high system effciency, and high power density. Simultaneously, the outer rotor structure enhances driving torque, and the newly developed aerodynamic impeller for this motor can provide high effciency even at full load or under partial loads.Romulus is equipped with commonly used signal input and output interfaces in the industry, enabling smart control through Modbus communication. Furthermore, the professional design of this series allows for a wider effcient operating range, while achieving high power density and low noise levels at operating points.

High Effciency

• The clever combination of the motor and impeller allows for unobstructed airflow into the impeller, achieving high transmission effciency with the motor directly driving the impeller shaft. The high-effciency motor surpasses the industry's highest IE5 energy effciency standard, with high power  density. The motor features an independently integrated electronic control cooling system for higher effciency. The fan achieves a static pressure effciency of over 70%, approximately 5% higher than competing products in the industry.

Low Noise

• The special geometric shape of the blades facilitates better gas flow, resulting in lower noise levels. The high-effciency motor and impeller design reduce noise levels by approximately 2 decibels at common operating points.

Easy Installation

• Convenient installation integrated installation method that is compact and superior in performance within narrow spaces, saving more installation space.
