Residential Use

Essential for controlling airflow between rooms, maintaining a comfortable temperature across the home. 

Commercial Use

Designed to regulate air quality and temperature in offices, conference rooms, and other spaces that require specific climate control.

Product Highlights
  • Butterfly Backdraft Damper

    Designed for heat exchangers, air exhaust systems, and HVAC applications where powered dampers are not needed. This damper works in both horizontal and upward air flow positions, featuring a foam seal for minimal air leakage and angled aluminum blades.

  • Motorized HVAC Damper (Normally Closed)

    Made from durable 28 gauge galvanized steel and available in a range of diameters from 4 inches to 14 inches. It is powered by either a 24-volt or 120-volt motor, with optional end switches.

  • Galvanized Wall Vent (Reversible Backdraft Damper)

    Features a gasketed backdraft damper that can be positioned for either intake or exhaust, along with an ⅛ inch insect screen to prevent pests, and an angled hood design for optimal airflow.

HVAC Dampers Installation Tips
  • Proper Placement

    Install HVAC dampers where pressure build-up is likely to occur. Some dampers can be integrated with zone controllers to automate airflow management.

  • Damper Selection

    Choose dampers based on climate and specific ventilation needs.

  • Professional Installation

    While some dampers may be installed by DIYers, professional installation is recommended for complex systems or areas with challenging access.

Frequently Asked Questions

What is the primary purpose of HVAC dampers?

HVAC dampers regulate and control the airflow within an HVAC system. Dampers are installed in ducts to adjust the volume of air reaching different parts of a building or space. By opening or closing, dampers allow for better temperature control, zoning, and air distribution efficiency.

How do I choose the right HVAC dampers for my needs?

Choosing the right HVAC dampers depends on several factors. Determine whether you need manual or motorized dampers. Motorized dampers are ideal for systems requiring automated control and zoning. In addition, opt for dampers that match the size of the ducts and airflow requirements. A properly sized damper ensures optimal airflow regulation and system efficiency. 

What warranty is provided with HVAC dampers?
