They have the ability to completely stop the airflow and also available with multiple blades when it is necessary. A zone damper (also known as a Volume Control Damper or VCD) is used specifically to control the flow of air in an HVAC heating or cooling system. The whole body construction is made up of extruded aluminium. Install volume control dampers in lined duct with methods to avoid damage to liner and to avoid erosion of duct liner. They can be used in intake, exhaust, or mixed air applications. Opposed blade dampers have blades that move in opposite directions. These dampers can also be adjusted for use in air mixing zones for heating and cooling air. As with the second style of electrical zone dampers, these dampers automatically return to the default position without the application of any power, and the default position is usually “open”, allowing air to flow. Another important fact about Butterfly dampers is that they are capable of preventing back-draft by only enabling the air to flow in a single direction making them a suitable choice for fire prevention and heating application. Each of these HVAC dampers serves different purposes. Mississauga, ON, L5T 1X6. There are two categories of control dampers – Commercial Volume Control Dampers and Balancing Dampers. Your email address will not be published. There are 2 main types of electrical zone dampers: For vacuum-operated or pneumatically operated zone dampers, the thermostat usually switches the pressure or vacuum on or off, causing a spring-loaded rubber diaphragm to move and actuate the damper. Lake Worth, Fl. It can be used as a positive shutoff, and can also be used for automatic control in low-leakage HVAC systems, or systems requiring modulating airflow. In large commercial installations, vacuum or compressed air may be used instead. Volume control damper can be mounted either … Guillotine dampers are best known for their capability to provide the best Seal possible. These dampers have multiple blades designed around a central hub improving the fan’s performance by introducing swirl into the fan inlet offering an excellent method of control. For example, in a house, the main floor may be served by one heating zone while the upstairs bedrooms are served by another. This type of dampers is particularly used for its quick response time and strong air blocking properties. Required fields are marked *. The location of a damper, its ducting structure and it’s the purpose all together determine the type of it. These dampers are single blade, two blades, three blades, multi blades & custom built as per the required opening size. The following are five types of dampers commonly found in HVAC system. Your HVAC system might even need all of these above-mentioned dampers working together. Volume control dampers are offered with either parallel or … This site uses Akismet to reduce spam. The flow can be controlled with the help of set screw provided on the damper handle to regulate the desired air flow. Butterfly Flat Dish Circular Damper ( BFD ), XJ-2 Portable Negative Pressure Isolation Unit, Difference Between Dampers and Louvers - EB Air Control, Prevention of Cross Contamination and contaminants spread, 7 Types of Damper and When To Use Them - Daily News Bite. This allows air to continue to flow while the heat exchanger in a furnace cools down after a heating period completes. Install backdraft or control dampers (as identified on the drawings) at inlet of exhaust fans or exhaust ducts as close as possible to exhaust fans unless otherwise indicated. VOLUME CONTROL DAMPERS Standard duty flanged style frame dampers, available with various blade types and controls. Control dampers are installed at various points in the duct work to regulate the flow of air through the system. Volume Control damper is widely used in heating, ventilation and air-conditioning applications (HVAC Damper) in order to maintain or control the air volume inside the duct. More specifically, it’s a valve or plate that stops or regulates the flow of air inside a duct, chimney, Variable Air Volume (VAV) box, air handler, or other air handling equipment. The damper sometimes can also be used for the other purposes like for directing an air stream to flow in a particular direction, just by allowing the blades to turn at the precise angle. These dampers facilitate the air flow to each zone and each room to be controlled during testing & commissioning. Manual dampers are turned by a handle on the outside of a duct. 1317 N.
