Dayton 4HX72 backdraft damper is suitable for ventilation systems to control the flow of air and prevent backdrafts, ensuring efficient ventilation and maintaining desired air pressure differentials. It is installed in exhaust or supply air ducts, especially in areas where maintaining proper air circulation & preventing the reversal of airflow is essential.

Frequently Asked Questions:

Q. What is the ambient temperature of this backdraft damper?

A. It has a maximum ambient temperature of 180 degrees F.

Q. How to know if my Dayton 4HX72 backdraft damper is installed correctly?

A.

• Ensure the blades move without obstruction upon installation.
• Place the damper in a level orientation, avoiding any twisting of the damper frame.
• If the mounting surface is uneven or if the blades experience resistance, allow some slack in the mounting screws.

Q. What are the factors to consider while choosing a backdraft damper?

A.

• The direction of airflow.
• The type of damper operation (gravity-driven or motorised).
• Requirements for system velocity and back pressure.
• The preferred mounting configuration (inserted into the duct/opening or flange mounted).

Q. What is the appropriate location for a damper?

A.

• In symmetrical structures, installing dampers on both lower and upper floors is recommended.
• In the case of asymmetrical or flexible structures, the middle floors often offer the most suitable placement for achieving the most effective location of the dampers.
