The EC ductfan is controlled with the external control signal 0-10 V (air capacity control as a function of temperature, pressure, smoke conditions and other parameters). Should the control value get changed, the EC-motor adjusts its speed and the fan boosts as much air capacity to the ventilation system as required. Maximum speed of the fan does not depend on the current frequency and it can operate at 50 or 60 Hz mains supply.
The fans may be integrated into the unified dispatch system.
The respective software enables to control all the fan integrated into the system. The computer display shows all the system parameters. Each fan in the system may be individually adjusted.

EC duct Fan Application
Supply and exhaust ventilation and air conditioning systems for various premises requiring cost-effective solution and controllable ventilation. EC motors applied in fans reduce energy demand by about 35% and ensure high aerodynamic performance and low noise level.
Such characteristics are of special importance for ventilation of public premises as banks, supermarkets,
restaurants, hotels, installation close to residential buildings and for domestic application, e.g. ventilation of private pools. EC motors enable integration of several fans into a unified networks and their centralized control.
