FAQ

1. How Does ventilator equipment work?

Ventilator equipment moves air efficiently to maintain proper airflow and indoor air quality. It typically consists of a motor, fan blades, and a housing. The motor powers the fan blades to push or pull air through ducts or open spaces.

By circulating air, removing heat, fumes, or stale air, and supplying fresh air, ventilator equipment supports industrial ventilation systems, commercial buildings, and custom supply ventilation systems.

2. What is an EC ventilator?
   EC ventilatorsuse Electronically Commutated motors, combining the advantages of AC and DC. The motor runs on DC voltage but can be powered by standard AC supplies, offering efficient, quiet, and precise airflow control.

3. How do EC ventilators differ from DC and AC ventilators?

EC ventilators use electronically commutated motors, which allow precise speed control, high energy efficiency, and quiet operation.

AC ventilators run directly on AC power, providing robust and continuous airflow.

DC ventilators use DC motors for quieter, energy-saving operation and flexible speed adjustment.

4. What are the advantages of EC ventilators?
   EC ventilatorsoffer energy savings, quiet operation, long service life, and smart speed control. They are ideal for applications where efficiency, low noise, and precise airflow are important, such as offices, factories, and commercial buildings.

5. What is the voltage of EC fan?

EC fan operates under both AC and DC voltages, ranging from 380V, 220V, 110V to 48V, 24V and 12V.
