VENTILATION DAMPERS
THE IMPORTANCE OF VENTILATION DAMPERS
Ventilation dampers are a critical part of indoor air quality systems, helping regulate and direct airflow for both comfort and efficiency. Whether part of a balanced fresh air system, zone control setup, or exhaust solution, dampers give contractors and system designers precise control over when and how air moves through a space.
Since 1927, Field Controls dampers have been engineered for smooth, responsive operation — helping systems meet ventilation codes, improve HVAC performance, and operate more efficiently. Available in multiple styles and configurations, they integrate easily with central HVAC systems or standalone ventilation equipment.
THE FUNCTION OF DAMPERS
Improve Energy Efficiency: By closing off airflow when it’s not needed, dampers help reduce standby losses and prevent unnecessary air movement.
Support Ventilation: Dampers maintain proper pressure and flow to prevent over- or under-ventilation.
Control Airflow Timing and Direction: Dampers open and close based on demand, ensuring air is delivered only when and where it’s needed.
Meet Code Requirements: Cuts down on the energy needed to condition incoming air, especially in areas with extreme temperatures
Meet Code Requirements: Proper damper use ensures compliance with standards like ASHRAE 62.2 and Title 24 by helping manage continuous or demand-controlled ventilation rates.
TYPES OF VENTILATION DAMPERS
Fresh Air Dampers regulate the introduction of outdoor air into the HVAC system, opening and closing based on ventilation demand or schedule. They help maintain indoor air quality and pressure balance, and are commonly paired with ventilation controls to meet code and comfort requirements.
Spring Closed Damper use a spring mechanism to stay closed when not powered, preventing unwanted air infiltration. When energized, the damper opens to allow airflow, making them ideal for controlled fresh air intake and demand-based ventilation setups.
Backdraft Dampers allow airflow in one direction and close automatically when air stops or reverses. They’re commonly installed in exhaust lines to block outdoor air from re-entering the system and to prevent cross-contamination between zones.

Excess humidity can lead to mold, odors, and poor indoor air quality, but not all solutions are equal. This guide compares portable and whole-house dehumidifiers, breaking down how each works, their pros and limitations, and which option best addresses your home’s moisture challenges.
Standard 1-inch HVAC filters often fall short on airflow, lifespan, and particle capture. FlexFilters offer a smarter solution with expanded surface area, balanced airflow, and longer service life—helping protect your system while improving indoor air quality.
Your HVAC system moves air through your home all day long, but without proper filtration and purification, it may also be circulating dust, allergens, mold spores, microbes, and chemical pollutants. These contaminants can repeatedly cycle through your ductwork and living spaces, affecting comfort and long-term health. Understanding how HVAC airflow works and why standard filters often fall short can help homeowners take the right steps to improve indoor air quality and reduce airborne contaminants throughout the home.
A media air cleaner is a whole-home filtration upgrade that integrates directly into your HVAC system to capture more airborne particles, improve airflow, and extend filter life. Unlike standard 1-inch filters, media air cleaners use deep-pleated filters and sealed cabinets to deliver cleaner air throughout your entire home with less maintenance.
Indoor air can be up to five times more polluted than outdoor air, particularly in energy-efficient homes that are tightly sealed, allowing pollutants like germs, VOCs, and odors to accumulate over time and potentially cause health problems for residents. Learn how a whole house air purifier can help.
Your HVAC system may be circulating more than just air. Dust, mold, and bacteria can build up and impact your health. Discover how whole-home purification helps.
