Talking about pipe ventilator

Duct fan is a kind of fan. The motor drives the fan blades to rotate and drives the airflow to exchange the internal and external air. Also called duct fan or duct fan. The purpose of ventilation is to remove the indoor dirty air and regulate the temperature, humidity and sensory effect. Duct fans are widely used in homes and public places. DC fan, EC fan, CPU heat sink

There are three types of duct fans: exhaust, suction and combined. The exhaust type enters the air from the natural air inlet and discharges the dirty air through the fan; The suction type draws in fresh air through the fan and discharges dirty air from the natural exhaust outlet; In parallel type, both exhaust and exhaust are supplemented by fans. The motor drives the fan blades to rotate and drives the airflow to exchange the internal and external air. It is also called a ventilation fan. The purpose of ventilation is to remove the indoor dirty air and regulate the temperature, humidity and sensory effect. Fans are widely used in homes and public places.

The air exchange rate and frequency are different in different places. The amount of fresh air required by one person or one square meter is called the required air exchange volume. The number of changes in fresh air within an hour is called the number of changes in air.

Advantages of duct fan

1. Wider scope of application.

2. Large air volume and low noise.

3. Wind tunnel design optimization and fan structure optimization.

4. The motor has excellent performance, quiet operation, long quality and long service life。
