BAROMETRIC DAMPERS
MAINTAIN BALANCED DRAFT FOR CLEANER, SAFER BURN
Barometric dampers play a critical role in oil- and gas-fired heating systems by automatically regulating chimney draft. When draft pressure is too strong, combustion can burn too hot and inefficiently; too weak, and it can lead to poor ignition and incomplete combustion.
Field Controls barometric dampers help maintain ideal pressure within the venting system, ensuring burners operate consistently, safely, and efficiently—regardless of fluctuating outdoor conditions or appliance cycling.
WHY DRAFT CONTROL MATTERS
Reduces Burner Overfiring
Dampers moderate excess draft to prevent the burner from drawing more air than needed, protecting against flame distortion and overfiring.
Improves Efficiency
Stable draft conditions lead to more complete combustion and help maintain fuel efficiency across varying system loads.
Protects Equipment
By preventing high flue gas velocities, barometric dampers help reduce wear on vent pipes and reduce heat loss.
Supports Safe Operation
Helps prevent nuisance burner lockouts, puffbacks, and poor ignition caused by unstable draft pressure.
HOW IT WORKS
Installed in the flue pipe, a barometric damper has a weighted, hinged door that opens or closes automatically in response to pressure changes. If draft becomes too strong, the damper opens to admit room air, reducing pressure. If draft drops, the damper closes to maintain stability.
Field Controls dampers can be adjusted by the installer for system-specific requirements and include precision balancing weights for fine-tuned performance.

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.
