Product & service detail

AIR DAMPER

Eusteel proudly offers advanced airflow control solutions through a wide range of high-quality Air Dampers. Every Eusteel damper is engineered with strict technical standards, ensuring exceptional durability and optimal performance across all environmental conditions.

Premium Materials for Superior Durability

All Eusteel dampers are manufactured using galvanized steel and brass — two materials known for their superior resistance to corrosion, heat, and mechanical stress. This ensures reliable, long-term operation even in high-humidity environments or areas exposed to chemicals and harsh weather.

Applications

Air dampers are suitable for all types of buildings and HVAC systems, from residential and commercial properties to industrial complexes.

Benefits and Features

Air damper helps minimize damage-causing factors such as moisture, rust, and chemicals, thereby increasing the lifespan and durability of the HVAC system. Additionally, the damper also helps reduce the impact of natural factors such as strong winds and high humidity, ensuring the HVAC system operates smoothly and efficiently.

Types of Air Dampers

🔹 VCD Damper

VCD Damper is used to maintain or control the air volume inside the duct.

Adjust airflow by adjusting damper blade opening with quadrant or screw handle.

The blades maybe parallel or opposed type depending on requirement.

VCD Damper can be mounted directly either on horizontal or vertical air duct.

Control: Quadrant, screw handle

Square VCD damper with lever handle

Round VCD damper with lever handle

🔹 Motorized Damper

MD Damper is used to adjust air flow by automatically adjusting the blades opening through the actuator.

The actuator receives input signals from the differential pressure sensor, building control system.

MD Damper can be mounted directly either on horizontal or vertical air duct

Control: Actuator Belimo, Nenutech, KLB, SMV, etc.

🔹 Non Return Damper

Non Return Damper is designed to allow air flow in one direction. When the blades open, they causes no signifi-cant pressure loss for the system.

For fan systems installed in parallel with the same air duct, NRD helps prevent reverse air flow when a fan stops operating.

NRD Damper always remains closed when the system stops operating.

🔹 Pressure Relief Damper

Pressure Relief Damper is a type of air damper designed to operate automatically in response to pressure fluctuations. When the air pressure exceeds the set limit, the damper opens, allowing air to escape. Conversely, when the pressure s below the set limit, the damper closes automatically.

PRD dampers are typically installed in duct systems within buildings and factories to ensure safety and protect the ductwork from damages when the system pressure exceeds safe limits.

🔹 Blast Damper

Blast Damper is a damper designed to protect the safety of systems, equipment as well as residents in a building when an explosion occurs.

Can withstand shock waves with pressure up to 5 bar,maintaining protective performance even when there are consecutive explosions.

Blast Damper can be installed in power plants, chemical factories, warehouses and places where there is a high risk of fire and explosion.

With cutting-edge technology, high-grade materials, and versatile design, Eusteel’s range of Air Dampers offers the perfect solution for any HVAC system—whether in commercial buildings or industrial facilities. We are committed to delivering efficient, safe, and long-lasting air control solutions that elevate the comfort, safety, and sustainability of every space.
