The non-return damper flap on the pipe connector stops the intake of cold outside air as well as the return flow of exhaust air. The flaps automatically close as soon as the air flow ceases and open when the fan pushes exhaust air outside. The flaps need to be horizontally oriented in order to close effectively.
In addition to being utilized for HVAC and Heat Recovery Systems, the professional metal connection with backdraft shutter can also be used for passive ventilation, whole-house ventilation, air conditioning hose connectors, vent connectors, and whole-house ventilation.

The mixed flow inline duct fan features a lightweight, double-insulated ABS body, offering strength and ease of installation. Its central motor and impeller allow for simple maintenance and versatile placement in any pipeline.

It is a ventilation fan with a two-way linkage. It can also expel heated air masses and draw in cold natural wind to provide ventilation in addition to removing smoke. High-quality, steady, quiet, wear-resistant sleeve bearing motor. Easy operation with overheat protection, effective temperature fuses, and safer operation On the initial pull, the fan activates and vents upward. On the second pull, the fan operates in reverse and blows air inward. The third pull will cause the louver to close and the ventilation fan to turn off.
