Rectangular Air Damper

Rectangular air dampers are devices used to regulate airflow in ventilation systems. They are usually used in air conditioning and ventilation systems in industrial, commercial, and residential buildings, and are generally made of galvanized steel, stainless steel, or aluminum alloy. The rectangular air damper effectively controls exhaust and return air by adjusting the blades, which is essential to maintain normal air circulation in air conditioning and ventilation systems.

Precise Airflow Control
Rectangular air dampers offer exceptional precision in controlling airflow within ductwork systems. They are equipped with adjustable blades that can be precisely set to different positions, allowing for fine-tuning of the amount of air passing through. In a typical commercial HVAC (heating, ventilation, and air conditioning) setup, the airflow rate can be adjusted within a relatively narrow range by carefully adjusting the blades of the rectangular air damper. Airflow adjustment accuracy can be as low as ±5% of the desired flow rate. The ability to precisely control airflow helps maintain a consistent and comfortable indoor environment.

Durability

Rectangular air dampers are usually made of galvanized steel, stainless steel, or aluminum alloy with a thickness of 1.2 mm. They have been pressure tested and can withstand a pressure of at least 500 N without significant deformation or damage. This means that during the normal operation of the ventilation system, the rectangular air damper can maintain good physical condition regardless of pressure fluctuations caused by airflow or possible minor impacts from external objects. In addition, the rectangular air damper can operate normally in a temperature range of -20℃ to 60℃ and a relative humidity of 30% to 95% without significant performance impact. It has strong environmental adaptability and can operate stably in both the cold winter in the north and the humid summer in the south. Under normal use and maintenance conditions, the average service life of the rectangular air damper can reach more than 10 years.

Wide Range of Airflow Capacities
One of the great benefits of rectangular air dampers is their wide range of airflow capacities, from 150 to 1300 CMH (cubic meters per hour). This wide range makes them suitable for a variety of applications within spaces of varying sizes. For example, in a small office, a lower airflow setting within this range may be sufficient to maintain a comfortable environment, while in a larger commercial area or industrial facility, a higher airflow rate may be selected to meet greater ventilation needs.
