At the most elevated level, there are 2 different types of applications: HVAC (Heating, Ventilating, and Air Conditioning) applications and Industrial Process applications. Air Dampers are machines that utilize movable blades to manage the wind current from one side of the damper to the next, which might be situated inside ventilation places, between rooms, or between the outside and inside of a structure.
Dampers are much more than basic wind stream agents. They are vital to the control of cool, warm, high temperature, messy, or even harmful air. They may likewise be utilized for fire security. A high-temperature bubble-tight damper keeps up with air quality and gives specialist security, which is the reason they are fundamental for modern wind current guidelines.
Moreover, what settles on dampers the most ideal decision for enormous and muddled systems are the range of plans accessible – this permits you the adaptability to pick the sorts of dampers most appropriate for your modern handling system. This article will look at the different types of dampers that simplify the ventilation process.
Isolation Dampers
Isolation dampers are fabricated for viable shut-off and seclusion of at least one level of channels in a perilous duty containment exhaust system. The high-temperature bubble-tight damper is our best-in-class damper. They are utilized for the isolation of a filter or channel bank basically during the filter change-out process.
In a biohazard climate, the dampers empower the air filtration framework to be stopped for cleaning or channel evolving. Our fast-acting shut-off damper is uniquely intended to give affordable disengagement of filter banks with high volumes of air.
An assortment of sizes and setups are accessible for a wide scope of dampers and downflow induction units. These dampers are accessible in round, square, and rectangular formed housing, making them versatile to most applications.
Our round isolation damper is intended for fixing off or potentially controlling wind streams in round conduits and pipes. The square isolation damper is intended for use as a solitary damper in ventilation work. Rectangular dampers are gathered in different setups to frame a filter bank for any size housing design. We ensure a bubble-tight seal at a differential strain of 10 inches water gage.
Multi-blade Control Dampers
Multi-blade control dampers are frequently alluded to as rectangular dampers or multi-cutting blade louvre dampers. These dampers are regularly found in two assortments dependent on the cutting blade activity – the direction of the sharp blade pivots in the control damper.
Parallel blade activity implies that all cutting blades open and close at a similar point and direction. Opposed blade activity implies that neighbouring cutting blades turn in inverse ways.
As an extremely basic principle, parallel sharp blade dampers are utilized for open/shut activity and against cutting blade dampers are utilized for tweaking damper activity. They are fast-acting shut-off dampers designed for multiple purposes.

Difference Between Dampers and Louvers
Notwithstanding, equal cutting edges offer better control of wind stream close to the furthest limit of the working reach (close to full open or full close positions). Opposed blades offer better control of wind streams all through the whole working reach. Parallel blades are frequently used to direct or “toss” the air aside when that gives a benefit, while opposed ones give more laminar wind current.
Multi-edge control dampers can withstand temperatures more prominent than 1800°F and pressures more noteworthy than 60 in. wg. This makes them ideal for various modern cycles and applications.
Parallel blade dampers might be utilized in gas turbine channels and outlets, fan deltas, atmospheric fumes, scrubbers/oxidizers, and precipitators. Opposed blade dampers are brilliant for quick power age, air filtration deltas, release the source for fans, and glass or metal treating frameworks.
Single Blade Dampers
Single blade dampers are regularly alluded to as butterfly dampers or wafer dampers. blades dampers can be provided in round, square, or rectangular assortments. The sharp edges can be of a solitary thickness or twofold skin airfoil plan. Much of the time, a single-blade damper can offer an affordable productive option in contrast to a costly valve.
Butterfly dampers can be utilized in a wide assortment of uses, however. are normally utilized for stream control and low spillage or segregation applications. These dampers can likewise be intended to withstand outrageous plant pressures and exceptionally high temperatures, while additionally keeping pressure drops low through the system. Single blade dampers can be utilized in frameworks with destructive and grating wind currents, making them ideal for natural controls and wastewater treatment applications.
These three different types of dampers are the most used dampers with the downflow induction unit. They have various applications in different industrial settings. While making the choice of which damper to choose, always focus on its operational capabilities rather than the cost and the system within which it has previously operated.
A bubble-tight damper provides isolation and containment of the airstream. Here are the different types of bubble-tight dampers for various applications. For more information about dampers, kindly contact EB Air Control.
