Self-operated Slim Hanger Fan

Built-In-Wall Type with Integrated Functions for FD and BDD
Self-operated Slim Hanger Fan

Structure

The Self-Operated Slim Hanger Fan is easy to install as it can be mounted on the wall for air supply and exhaust. For some existing fans, a Fire Damper(FD) and a Back Draft Damper(BDD) are installed inside the main duct, but the Self-Operated Slim Hanger Fan is made up of a centrifugal speed regulator and a shutter with integrated functions of FD, BDD and louvers all in one. The shutter equipped with the centrifugal speed regulator is opened and closed by the rotaing masses installed on both sides of the speed regulator, and therefore, the shutter is opened fully so that vibration can be prevented and high fan efficiency can always be maintained. When the fan is off, the shutter is closed fully by spring action.

Characteristics

• Space saver, wall mounting eliminates need for fan rooms
• Fast and easy installation saves money in construction expenses especially in low ceiling buildings save construction costs for the building with low ceiling
• Simple structure with integrated FD, BDD and louvers
• Easy maintenance with simple system
• Installation cost savings without separate square-ducts
• The system is stable, as louvers with FD and BDD functions are open and close by use of centrifugal force of the fan. Also there is no damper noise as louvers are open and close by use of the speed regulator.
• Installation of a round Venturi on the discharge side prevents air from recirculating or short cirfuiting. It is to maximize the fan efficiency by reducing energy loss.
• The 6-blade propeller is statically and dynamic balanced for low noise and low vibration.
• The belt transmission ensures low propeller rpm, which ensures high efficiency, low energy consumption as well as low noise.
