By regulating the flow of air in each room or zone, you can ensure that only the necessary amount of heating or cooling is being used. Controlling the amount of outdoor air introduced to the HVAC system also has a tremendous impact on energy usage. Introducing more outdoor air than necessary can quickly become expensive. AWV volume controlled dampers can significantly reduce your energy costs by allowing HVAC systems to be properly balanced to the design specifications.\u003C\u002Fp>\u003Cp>In addition to energy savings, volume controlled dampers can also improve indoor air quality. By allowing you to properly adjust the flow of air in each room or zone, you can prevent the build-up of stale or polluted air.

Both gravity and motor operated options available.","\u003Cp>Backdraft dampers are a specialized type of damper designed to prevent air from flowing the wrong way in an air duct. Often thought of as check valves for ductwork, backdraft dampers keep air flowing as it should. High-quality design and attention to detail are the keys to building reliable, easy-to-maintain backdraft dampers.\u003C\u002Fp>\u003Cp>How Do Backdraft Dampers Work?\u003C\u002Fp>\u003Cp>Backdraft dampers are designed to open under a certain air pressure with the blades of the damper returning to the closed position as the air pressure decreases. Backdraft dampers serve as one-way or check valves for ductwork, keeping air flowing in the direction it is supposed to and preventing backflow.\u003Cbr \u002F> \u003C\u002Fp>\u003Cp>\u003Cstrong>Linkage\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>Depending on the application and damper design, the blades of a backdraft damper can be linked or independent. Linked damper blades open and close uniformly because they are mechanically connected. Independent blades are able to open and close regardless of what the other damper blades are doing. With linked damper blades, the opening and closing operations are typically smoother but the entire damper can become inoperable if a blade is damaged or becomes stuck.\u003Cbr \u002F> \u003C\u002Fp>\u003Cp>\u003Cstrong>Counterbalancing\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>Blade design and counterbalancing help ensure that backdraft dampers operate as designed. An ideal backdraft damper is able to open quickly with very little pressure drop and close off tightly as soon as the air pressure is decreased. Counterbalancing makes this possible, either by adding counterbalancing to the damper blades or to the arm outside of the air stream. \u003Cbr \u002F> \u003C\u002Fp>\u003Cp>\u003Cstrong>Blade Seals\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>Weighted counterbalances help the backdraft damper to seal against air flow, however, additional blade seals are sometimes required. Blade seals improve the surface on the edge of the backdraft damper blade, and allow for a tighter seal to be generated as the damper closes. With blade seals, backdraft dampers can withstand much higher back pressures with less leakage.\u003Cbr \u002F> \u003C\u002Fp>\u003Cp>Backdraft Damper Applications\u003C\u002Fp>\u003Cp>Backdraft dampers show up in many locations where airflow needs to flow in only one direction including:\u003Cbr \u002F> \u003C\u002Fp>\u003Cp>Clean air systems\u003C\u002Fp>\u003Cp>Bathroom fans\u003C\u002Fp>\u003Cp>Exhaust hoods\u003C\u002Fp>\u003Cp>Fan walls\u003C\u002Fp>\u003Cp>Industrial Fans\u003C\u002Fp>\u003Cp>Most exhaust systems will have a backdraft damper included to prevent air from reversing direction. Bathroom fans and exhaust hoods also typically use backdraft dampers since the flow of air through them may not be continuous. The backdraft damper prevents unconditioned outdoor air from flowing into the building when not actively exhausting air.\u003C\u002Fp>\u003Cp>Many fan wall assemblies utilize backdraft dampers to allow equipment to continue to operate even with the loss of a fan. Fan walls in air handlers (consisting of multiple fans in parallel) use the pressure generated from active fans to open the damper while allowing the backdraft dampers to isolate any fans that may not be functioning properly.\u003C\u002Fp>\u003Cp>Backdraft dampers can be made in many sizes, shapes, and materials based on the application. Square and round backdraft dampers are very common. Most backdraft dampers are made from galvanized steel with aluminum that can be used in applications needing spark resistance and stainless steel providing corrosion resistance. \u003Cbr \u002F> \u003C\u002Fp>\u003Cp>American Warming and Ventilating (AWV) Backdraft Dampers\u003C\u002Fp>\u003Cp>American Warming and Ventilating (AWV) offers \u003Ca target=\"_blank\" href=\"https:\u002F\u002Fawv.com\u002Fproducts\u002Fdampers\u002Fbackdraft\u002F\" rel=\"noreferrer noopener\">a wide selection of backdraft dampers\u003C\u002Fa> in various frame sizes up to 48” x 96”.

They are often used to regulate the flow of air in order to maintain a safe and comfortable environment for passengers and vehicles in the tunnel and to help regulate the distribution of smoke and hazardous gasses in the case of a fire.\u003C\u002Fp>\u003Cp>High humidity and unclean air mean these often hard to access dampers must be built by reliable and trusted manufacturers.

They can be installed in the air intake or exhaust vents of a tunnel to control the flow of air and maintain the desired air pressure within the tunnel.\u003C\u002Fp>\u003Cp>AWV has a wide range of tunnel dampers to suit the specific needs of your application. With many mounting options and leakage rates, AWV tunnel dampers are designed to meet the needs of any application.

For metro systems, pressurized air can form in front of a fast moving train, known as the piston effect. Tunnel dampers are used on incoming and outgoing sides of the station, as outgoing trains pull air while incoming trains push air. In emergency situations, many tunnel dampers are controlled remotely to keep fire and smoke blowing away from people as passengers escape the tunnel.\u003C\u002Fp>\u003Cp>AWV dampers are designed to withstand the rigors of the toughest environments, to help ensure reliable performance and long-lasting durability. AWV tunnel dampers are ready to work when they are needed most. Because of the tough requirements of the applications, tunnel dampers must meet certain specifications including NFPA-130, NFPA-502, UL 555S, and BS 476 (UK) standards. AWV offers tunnel dampers to meet all of these certifications, although we are not always required to. For example, BS 476 is not always required to be met in the US, but AWV tunnel dampers are fabricated in such a way as to exceed the limits for BS 476 compliant construction.\u003C\u002Fp>\u003Cp>Able to operate with face velocities up to 8,000 fpm and with pressure differentials of up to 60” wg, AWV dampers can meet any application’s requirements, even though 4000fpm and 40 in wg is the more practical limit. AWV also offers tunnel dampers with optional blade arrangements, blade seals, and the ability to operate in per the minimum NFPA requirement of 305°F. That said, 482°F is more commonly spec’d, and internationally 752°F is occasionally seen.\u003C\u002Fp>\u003Cp>Our team of experts can help you design the best tunnel damper solution for your application.
