The devices that make together hot and cold air circulation in different systems are called axial fans.
Roof type fans are used as aspirators by connecting to air ducts or directly mounted.
Duct type fans are the fans that are arranged according to the shape of the ducts in the ventilation system and placed inside the duct.
Cabinet type ventilators are used in places where only ventilation is needed without heating or cooling. Depending on the physical properties of the air, the unit can be designed with low or high suction/blowing capacity to clean ambient air.
Heat Recovery Devices are designed to save energy by using the exhausted air from the area to give fresh air in ventilation applications.
