Description

Louvre dampers (also spelt as louver) play a crucial role in regulating the flow of air and managing pressure drop in various applications. These dampers (or multi-vane louvre dampers) consist of angled louvre blades or angled slats mounted parallel across a duct. The blades can be adjusted to control the amount of air passing through.

One of the key advantages of louvre dampers is their wide range of applications. They are commonly used in HVAC systems, industrial processes, and power plants. The ability to throttle flow and adjust air pressure makes them essential for maintaining optimal conditions in these environments.

Louvre dampers are made of stainless steel for durability and long-lasting performance in harsh operating conditions. They can quickly act as an air shutoff by closing tightly to prevent any unwanted airflow.

By utilizing louvre dampers, industries can achieve precise control over airflow, improve energy efficiency, and maintain a safe working environment. Their versatility and reliability make them an indispensable tool for managing air movement in various applications.

Laminar’s line of louvre dampers provides reliable control and isolation. Our designs offer quick response and fast operating cycles. They are capable of providing reliable and repeatable flow control for all applications.

They provide a combination of flow control for the air and gas in dry or wet conditions and can be isolated.

FAQ's

A damper is primarily designed to control airflow or gas flow within a system. It is typically used in HVAC systems, ventilation systems, or industrial processes to regulate the volume of air or gas passing through ducts or pipes. Dampers are commonly found in buildings, factories, and power plants to ensure proper ventilation, temperature control, and energy efficiency.

On the other hand, valves are more versatile and can be used in a wide range of applications beyond airflow control. Valves regulate the flow of liquids or gases by opening, closing, or partially obstructing passages within a system. They are commonly employed in plumbing systems, oil refineries, chemical processing plants, water treatment facilities, and many other industries.

While dampers and valves can control fluid flow or movement within a system, their designs differ significantly based on their intended applications. Dampers often feature blades or vanes that adjust the passage size to modulate airflow. Valves come in various forms, such as ball, gate, globe, and butterfly valves – each with specific mechanisms tailored for different purposes.

In summary, while dampers focus on controlling airflow specifically within HVAC systems and industrial processes, valves have a broader scope of application for regulating fluid flow across multiple industries.

There are many types of louvre dampers. Some common ones are:

  1. Parallel Blade Louver Dampers: This type of damper consists of multiple blades that move in unison, parallel to each other. They are commonly used in HVAC systems and provide excellent control over airflow rates.
  2. Opposed Blade Louver Dampers: Unlike parallel blade dampers, opposed blade dampers have blades that move in opposite directions. This design allows for more precise control over airflow and is often used in applications requiring tight shut-off.
  3. Multiblade Louver Dampers: As the name suggests, multiblade dampers consist of several individual blades that can be adjusted independently. This versatility allows for customized airflow control in various settings, such as industrial ventilation systems or commercial buildings.
  4. Combination Louver Dampers: These dampers combine louvres with other components, such as filters or screens, to provide additional functionalities. They are commonly used in applications where airflow regulation and particle filtration are necessary.
  5. Fire Dampers: They are designed to prevent the spread of fire. They are typically made of fire-resistant materials and have seals that close automatically in the event of a fire.

Each type of louvre damper offers unique advantages depending on the specific requirements of your ventilation system. Contact us to find the most suitable for optimal performance and energy efficiency in your application.
