The fan casing is made of steel with black polymeric coating.
The fans are equipped with high-efficient electronically-commutated direct current motors with external rotor and impellers with backward curved blades. The EC motor is free of friction and wear parts such as commutator and brushes. These components are replaced by a maintenance-free electronic circuit board. EC motors also feature high performance and easily controllable speed ranges. Premium efficiency reaching 90% is a definite advantage of electronically commutated motors.
The fan is controlled by an external 0-10 V control signal. The fan capacity regulation depends on temperature, pressure level, smoke content, etc. The fan has low energy consumption at any speed. Maximum fan speed does not depend on the available current frequency and is suitable for operation at both 50 and 60 Hz frequencies. Fans can be integrated into a single computer-driven control system. Custom designed software provides high accuracy control of the fans integrated into a network. The LED-display on the computer shows all system parameters and the operation mode can be set individually for each fan in the network.
The fan is mounted on the roof directly above the ventilating duct or shaft and is firmly fixed to a flat surface by means of a connecting plate. The screw holes in the mounting plate provide a reliable rigid fixing thus preventing water from entering the ventilation shaft. Electrical connection and installation should be performed in compliance with the manual.
