HVAC Air Duct Dampers

Adjustment depends on the damper type and its operating arrangement. Gravity dampers respond to airflow, while manually operated configurations are positioned through their control mechanism. Before changing a damper, identify its type and confirm the required airflow setting for the system. For industrial ventilation, consult the equipment documentation or request product-selection guidance.

A motorized damper uses an actuator to open, close, or position the damper without direct manual adjustment. This can support automated airflow control, system isolation, or coordinated ventilation operation. The product information provided for this category identifies gravity, butterfly, blastgate, and metric configurations; motorisation should therefore be confirmed for the specific application.

The available materials are PVC and CPVC. PVC dampers are fabricated from GF Harvel seamless extruded duct with Simona Versadur PVC Type 1 sheet. CPVC dampers use Georg Fischer Harvel Corzan CPVC duct and Simona PVC-C Corzan sheet. Material selection should reflect the chemical environment and ventilation conditions.

The product range includes gravity, butterfly, blastgate, and metric configurations. Each type provides a different approach to airflow control or duct isolation, so selection should be based on the ductwork arrangement, operating method, and application requirements. IPF can help match the configuration to an industrial plastic ventilation system.

PVC dampers are available in sizes from 4 inches to 24 inches, while CPVC dampers are available in sizes from 6 inches to 24 inches. The appropriate size should correspond to the connected ductwork and system design. Confirm dimensions and configuration requirements when requesting a quotation or product-selection assistance.

These dampers are intended for airflow control in plastic ventilation systems, ductwork damping applications, and industrial ventilation systems. Their thermoplastic construction is suited to environments involving harsh, chemical-laden gas streams. The correct material and damper type depend on the chemical conditions, ductwork design, and operating requirements.
