Non-UL Dampers - Arrow

Sub Types

Control Dampers

Direct airflow to where it's needed. Our control dampers are designed for efficient airflow. Available for on-off and modulated flow applications.

Balancing Dampers

Alleviate drafts and cold/warm spots in your building. Balancing dampers maintain even air pressure across your duct. For smooth and efficient airflow.

Backdraft Dampers

One-way flow control without an actuator. Backdraft dampers open and close automatically with airflow. Choose from square, rectangular, and round models.

Round Dampers

Spiral ducts need round dampers. This category includes control, balancing, and backdraft dampers for round ductwork.

Industrial Dampers

Control and balancing dampers for industrial HVAC. Designed and built for heavy-duty applications.
