Pipeline Ventilation Fan

A duct ventilation fan is a type of air conditioning device that is driven by an electric motor to rotate the blades and drive the airflow, enabling indoor and outdoor air exchange. Also known as pipeline fan or pipeline fan. The purpose of air exchange is to remove indoor dirty air, regulate temperature, humidity, and sensory effects. Pipeline ventilation fans are widely used in households and public places.
There are three types of ventilation methods for pipeline ventilation fans: exhaust, suction, and combined. The exhaust type enters the air from the natural air inlet and expels dirty air through a ventilation fan; The suction type sucks in fresh air through a ventilation fan and expels dirty air from the natural exhaust outlet; The combination method is that both suction and exhaust are completed by a ventilation fan. A type of air conditioning appliance that is driven by an electric motor to rotate the fan blades and drive the airflow, enabling the exchange of indoor and outdoor air. Also known as a ventilation fan. The purpose of air exchange is to remove indoor dirty air, regulate temperature, humidity, and sensory effects.

The amount and frequency of air changes required vary in different locations. The amount of fresh air required for a person or per square meter is called the required air exchange rate. The number of times fresh air is changed within an hour is called the number of air changes.
