We know that combo air control dampers are not generally a part of your day-to-day conversations, but it’s important to know how your system works and ensure it’s being maintained properly. Lloyd Industries has covered everything you need to know about the louver/damper combination and how it can benefit your system.

What Are Air Control Dampers?

Air control dampers are used to control airflow inside heating and air conditioning ducts, chimneys, and other pieces of air-handling equipment. The dampers control the airflow into, out of, or in the space itself.

Air control dampers control the temperature in your home and building. We all know that one spot that is really hot or cold. Adjusting your dampers helps you control where your heating and cooling is going throughout your building. The movable plate is situated in the ductwork and is most commonly used with zone control systems.

Types of air control dampers include:

  • Parallel blade
  • Opposed blade
  • Single duct air
  • Single round air

What Is a Louver?

A louver is a type of damper that is used to protect HVAC systems from the elements while still allowing air to be pushed in or out of the building. Lloyd Industries offers a variety of combination louvers that are all lightweight, compact, and versatile.

Types of louvers include:

  • Channel frame
  • Flanged frame
  • Chevron blade
  • Drainable louver

How Combo Air Control Dampers Work

It’s exactly as you would suspect. The combination dampers work together to offer the features of the damper and the louver. The louvers act as a shutter or blind with horizontally angled slats that allow for light and air to pass through but restrict direct sunlight and rain. The blades can be opened or closed without having to close the damper.

Installing a Combo Air Control Damper

Proper installation of your louver/damper combination is crucial. If the product isn’t secured properly, it won’t work as intended, which can be harmful to your equipment. Feel free to install the products yourself if you are feeling confident or know your way around an HVAC unit. Lloyd Industries offers installation guides that you can download from the website to guide you along if you get stuck.

The most common types of combination louver/dampers are:

  • Intake/Exhaust combo
  • Flanged Frame combo

Lloyd Industries has local reps all over the country that you can hire to install your products and answer any questions you may have. They are professional and knowledgeable and able to give you peace of mind and ensure your system is running smoothly before they leave the site.

Why Use a Combo Air Control Damper?

The combination damper protects your system from the weather, including the likes of everything from rain to hurricanes and extreme winds. If you are looking to purchase a louver specifically for hurricanes or thunderstorms, it’s important to know the standards of your area.

Hurricane louvers are made with the elements in mind. Meant to protect against pressure from strong winds and flying debris, these louvers are keeping your system dry and ensuring the weather isn’t affecting your airflow inside by working alongside the air control damper.

If a nasty hurricane passes through, the slanted blades of the louver are meant to protect your system from the rain. Since we know rain doesn’t always fall straight down, the blades can be placed vertically or horizontally, depending on the building, customer needs, and the common weather conditions in the area.

Cities and states have different standards for installing combo air control dampers, so do your homework. Our highly trained reps are also knowledgeable of the requirements in your area. Ensuring these standards are put in place keeps your home or business safe during harsh weather.

5 Places to Install Combo Air Control Dampers:

  • Small spaces with limited ventilation
  • Storm shelters
  • Basements or attics
  • Garages and outdoor storage
  • Roofs

Many of these places are subject to inclement weather, so protecting your system while maintaining proper airflow is crucial.

Combo Air Control Damper Maintenance

Just like other parts of your HVAC unit, it’s important to schedule maintenance to maintain your louver and damper. Maintenance tasks include inspecting the outside vents and checking for any obstructions or stuck objects in the blades. Keep an eye out for dirt buildup and aggressive wear.

If working in a high-construction area, it’s important to clean the system thoroughly to keep it working as expected. And don’t forget to test that the blades open and close at least once a year.

Adjusting Your Combo Air Control Damper

Your dampers may need to be adjusted at some point. If you are noticing an inconsistency in the temperature throughout your building, it may be time to adjust your dampers. If you aren’t sure what dampers control what spaces, do a test throughout the building and take notes. Once completed, adjust your dampers accordingly and keep your notes in a safe place for next time. This will help you avoid confusion and keep control of the airflow in your building.
