A damper is something that controls the flow of air inside a room or space. There are different types of dampers that are used for different purposes.

Dampers are very important because they help us control the temperature inside our homes and other buildings. Dampers are also used to stop sound from traveling from one place to another. Without dampers, it would be impossible to have a nice, quiet conversation in any room of your house.

In this article, we will give you some information about the different kinds of dampers that are used for controlling the flow of air.

Butterfly Flat Dish Damper

Butterfly Flat Dish Damper

A butterfly flat dish damper is a device that fits over the top of a washer and dryer unit to prevent clothes from getting damp or soiled as the unit operates. It is shaped like a large butterfly with its wings spread wide apart and is attached to the top of the unit with screws. It has two round, rubberized feet that extend downward below the bottom of the washer or dryer unit and contact the floor.

This type of device is designed for use with top-loading units and it works well. If you have a front-loading washer or dryer, you can still use a butterfly flat dish damper, but you will need to get one that is specifically designed for front-loading units. You can also use a butterfly flat dish damper with a combination washer/dryer if you want to. Just make sure you get one that is designed for your particular model of washer and dryer.

Blade Dampers

A blade damper is a device used to reduce or eliminate vibration and noise in a rotating system. Blade dampers are installed between the rotor and the housing to absorb the shock of the blades hitting the sides of the vane slots. Blade dampers are used in fans, blowers and other types of equipment where there is a tendency for the system to vibrate and become noisy.

Blade dampers are made in a variety of ways. One of the most common is to use rubber or another type of elastomeric material. Another method uses a spring-like device called an “O-ring” to absorb the shock. 

Blade dampers are available in a wide range of sizes and are generally specified by the number of blades they are designed to dampen. Blade dampers are also available with or without a dust cover. Blade dampers are not required by law to have a dust cover, but it is recommended that they be used whenever possible.

Guillotine Dampers

Guillotine Dampers

A guillotine damper is a device that clamps down on the top of a pipe. The pipe is then cut off at the bottom, creating a “dead” end. The guillotine damper prevents air from escaping while the bottom of the pipe is being repaired. Guillotine dampers are used to repair water pipes. However, they can also be used to repair sewer pipes and drain pipes.

They are also used to prevent air from getting into the pipe when the pipe is being repiped or rerouted. This is important because if air gets into the pipe, it will cause the new material used to create the pipe to expand and crack. This means that the pipe needs to be replaced. If you use a guillotine damper, then you won’t have to worry about the new material from the expansion and contraction causing the pipe to crack.

Louver Dampers

A louver damper is a device that is used to control the flow of water from one part of a roof to another. It is installed over a gutter and consists of a horizontal slatted metal grille with louvers (slats) that are set at an angle to the vertical.

Water flows freely across the bottom of the damper, but gets obstructed as it passes through the louvers. The louvers are set at such an angle that the flow of water is directed down to the gutter, where it can be collected and removed from the building.

Multi-Blade Control Dampers

Multi-Blade Control Dampers

A multi-blade control damper is a mechanical device that controls the movement of a car’s shocks and struts. It is a very common component of a car’s suspension system. Multi-blade dampers offer several advantages over single-blade dampers. One of the main advantages is that they offer much better isolation. 

This means that they allow your car to travel over bumps, potholes, and rough roads with less bottoming out and more smooth sailing. Another advantage is that they allow your car to travel over uneven road surfaces with less harshness and a more comfortable ride.

Multi-blade dampers also offer a smoother ride and a more comfortable trip over bad roads. They isolate the movement of the car’s suspension from one another. When one blade bottoms out against a bump or a hole in the road, the other blades compress slightly, allowing the car to travel over the bump or rough spot with less harshness.

Single Blade Dampers

A single blade damper is a device that fits into the ductwork of an HVAC system. It looks like a long, thin piece of metal that has a curved portion at one end. The other end of the damper has a flat surface that contacts the inside surface of the ductwork.

There are two main purposes for using a damper. The first is to reduce the noise level of the HVAC system. This is especially important in areas where there are people who are sensitive to noise. The second purpose is to reduce the amount of air movement in the ducts. This reduces the amount of dust and dirt that is circulated throughout the building. A damper is an excellent way to make your HVAC system more efficient.

Pressure-Relief Dampers

Pressure-Relief Dampers

A pressure-relief damper is a device used to control excessive noise and vibration in a vehicle. It works by dissipating the vibrational energy of the engine into the air. This causes a “puff of air” which is then vented out of the vehicle through an exhaust system. Without a pressure-relief damper, all of the vibrational energy from the engine would be transmitted directly to the vehicle’s body. 

This would cause the body to shake and rattle and make an awful lot of noise. With the installation of a pressure-relief damper, all of this vibrational energy is dissipated before it reaches the vehicle’s body. As a result, the vehicle is much quieter and less likely to give the driver or passengers a headache.

Face and Bypass Dampers

A face damper is a device that hangs from the ceiling and extends downward over a fireplace. It has a round, metal plate with a hole in it that sits directly above the fire. Ashes fall through the hole and onto the metal plate. The plate has a series of vanes attached to it. 

As the heat from the fire rises, the air surrounding the face damper begins to rise too. This causes the air to exert a greater force on the metal plate. The result is that the metal plate is pushed slightly upward, which causes the vanes to deflect downward, and thus, dampens the flow of air and smoke.

A bypass damper works much the same way as a face damper, but it is installed above a forced-air heating or cooling system instead of a fireplace. The only difference is that the metal plate doesn’t have a hole in it. Instead, it has a slot cut out of it. The plate sits directly above the duct work that carries the heated or cooled air throughout the building.

Inlet Vane Dampers

Inlet Vane Dampers

An inlet vane damper is an automotive device that controls the flow of air into a combustion engine’s intake manifold. Inlet vanes are attached to a shaft that rotates within a housing. As the vanes rotate, they open or close passages that regulate the flow of air into the carburetor. This allows you to fine-tune the mixture of fuel and air to get the best possible performance from your engine.

Inlet vanes are made of a durable material such as stainless steel, so they will last a long time. You should check out this informative video about inlet vane dampers.

Isolation Dampers

An isolation damper is a device used to reduce the effects of vibrations and noise from one part of a building or vehicle to another. They are often used in the construction industry to reduce the transmission of vibrations and noise from a building site to the living quarters of the workers. They are also used in the automotive industry to isolate the interior of a vehicle so the driver and passengers are not subjected to unwanted road noise.

Isolation dampers are available in a variety of different designs and configurations. Some of them are passive, which means they rely on the integrity of the materials used to construct the building or vehicle to do their job. Other types are active, which means they actually contain some type of mechanical or electrical device that is designed to cancel out or reduce the effects of unwanted noises or vibrations.

Control Dampers

Control dampers are used in conjunction with a shock absorber on each wheel. This allows you to adjust the stiffness of the suspension. A stiffer suspension will provide better handling and control when driving over rough roads or when performing other high-stress maneuvers.

However, a softer suspension will provide a more comfortable ride, especially over rough pavement. Most people like to have a little “give” when driving over bumps or rough roads. This is where control dampers come into play. By adjusting the amount of resistance offered by the control damper, you can achieve the best compromise between handling and comfort.

Balancing Dampers

Balancing Dampers

A balancing damper is a device that is used to control the movement of a vehicle on a smooth surface. It works by using air pressure to push down on one side of the vehicle and pull up on the other side. This causes the vehicle to remain in an even position over its wheels.

If you have a car with automatic transmission, balancing dampers are a must. They prevent the car from spinning out of control and causing a wreck. Without them, your car will start to slide all over the road. Balancing dampers are also important if you drive a lot of miles on rough roads. They give your car a much more solid feel and keep the tires from being jarred around so much.

Backdraft Dampers

Backdraft dampers are designed to reduce the draft created by a fireplace or wood stove. They work by creating an airtight seal around the base of the flue. This prevents the flow of air from escaping up the chimney and also creates a tight seal around the fire to prevent it from spreading out too much.

Without a backdraft damper, the fire will burn with very little smoke until it gets going. However, once it gets going, it will quickly spread out and create a lot of smoke. This is very dangerous because it can cause a chimney fire or, in the case of a wood-burning stove, it can cause the house to burn down.

Multi-Zone Dampers

Multi-Zone Dampers

A multi-zone damper is a device used to control the temperature in different parts of a building. It does this by using a combination of a viscous fluid (oil) and a gas. The damper is placed in the ductwork which runs throughout the building. As the air passes over the damper, it is forced to pass through one of several orifices, each of which directs the air into a different temperature zone. 

The air is then allowed to continue flowing freely until it reaches another orifice, at which point it is forced through another section of dampers. This process continues until the air is allowed to flow freely into the room where it is desired to have a specific temperature.

Multi-zone dampers are used to maintain a constant temperature in different parts of a building. They are used in a variety of ways, such as to control the temperature in an office building, a school, a hospital, a manufacturing facility, or any other type of structure that has ductwork in it.

Industrial Dampers

An industrial dumper is a mechanical device used to unload bulk materials from a dump truck or other vehicle. It consists of a large hopper into which the bulk material is dumped, a conveyor belt that carries the material from the bottom of the hopper to a point above the hopper, and an inclined plate or ramp at the top of the conveyor belt that allows the material to slide off the conveyor belt and into a lower receptacle. 

An operator controls the movements of the various parts of the dumper from an operator’s station on the ground.

There are many different types of industrial dampers, but they all operate in basically the same way. The main difference is in the size of the various parts. Industrial dampers can be as small as a garbage disposal unit and as large as a dumper designed to unload semi-trailers. They are used in a wide variety of applications, including municipal solid waste collection, construction, mining, agriculture and forestry.


Which dampers do you use the most?

The most commonly used dampers are the variable speed, hydraulic motor driven, and the electro hydraulic. The variable speed dampers can be used on both the roof and the wall of the trailer.

Which type of damper is not useful for energy dissipation?

Hydraulic dampers are not useful for energy dissipation because they can only rotational motion, which is not good for energy dissipation. They are useful for low-frequency (damping) vibration control because they “passively” dissipate vibrational energy by converting it into heat. 

Where are dampers used?

Dampers are used on exhausts, intakes, and turbochargers. You’ve seen dampers on mufflers and on turbochargers. On a muffler, a damper will be a little metal box containing a piston.

Why do we use dampers?

Because the way the muffler is mounted to the car, there is a wide variety of frequencies that will hit the pipe. When you have a large number of frequencies hitting the pipe, the pipe itself will not resonate at any one frequency.

However, when a smaller number of high-frequency signals hit the pipe, the pipe will start to vibrate at the same frequency as the signals hitting the pipe. This causes an undesirable “resonance” in the pipe and can lead to a very loud sound. 


A damper is a device that is attached to a suspension system to reduce excessive vibrations caused by uneven road surfaces.

There are many types of dampers and they are essential for the smooth functioning of your vehicle. If you don’t know how to identify and use them properly, it will cause a lot of problems like squeaking and rattling noises which will be annoying to you and other people around you.

So, it is important for you to know how to identify and use the dampers correctly. We hope that after reading this article, you will be able to identify the different kinds of dampers that are used in different situations.
