This Raypak ventilation component is designed to regulate the flow of air in heating, ventilation, and air conditioning (HVAC) systems. The device consists of two main parts: a damper, which is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment; and a motor, which controls the opening and closing of the damper. The motor is typically electric and can be controlled manually or automatically depending on the system setup. This product from Raypak is made with high-quality materials for durability and efficiency. It is compatible with various HVAC systems and meets industry standards for safety and performance.
