What is the difference between a damper and a louver?

The Louver is a kind of a shutter or blind that comes with horizontal slats that are angled to allow space for light and air but restrict rain and direct sunlight whereas dampers control the airflow. In HVAC systems, dampers and louvers are used to regulate the flow of air.

What is a combination louver damper?

Combination louvers act as a louver/damper combination. They utilize fixed louver blades in the front and adjustable blades in the rear that can be opened or closed. These louvers are popular for warehouse applications and other structures in which you want to close the airflow without the use of a damper.

How does a damper actuator work?

Part of a heating, ventilation, and air conditioning (HVAC) system, a damper actuator controls the opening and closing of a damper. Opening the damper allows air from outside a building to enter, in order to cool the interior, or it can close to contain the inside air.

What is a louver actuator?

Actuators control the movement of adjustable blades on dampers and adjustable louvers. Actuators can be manually operated or automatically controlled, for two-position or modular action.

What are the different types of dampers?

In this guide, we will walk you through the main types of industrial dampers, and their applications, to help you with your decision making process.

• Multi-Blade Control Dampers.
• Single Blade Dampers.
• Backdraft and Pressure-Relief Dampers.
• Face and Bypass Dampers.
• Inlet Vane Dampers.
• Isolation Dampers.

What is difference between damper and valve?

As nouns the difference between valve and damper is that valve is a device that controls the flow of a gas or fluid through a pipe while damper is something that damps or checks:.

What are dampers used for?

A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control.

What are fire dampers used for?

Fire Dampers are used in air transfer openings, ducts and other places where fire rated structures (e.g. walls, floors or other fire barriers) are penetrated.

What is the difference between a damper and an actuator?

Dampers are the final control devices for almost all airflow in HVAC systems. Actuators are the interface between the control system and the mechanical system and are critical to accurate control.

What are the three types of actuators?

Actuators can create two main types of motion: linear and rotary.

• Linear Actuators.
• Rotary Actuators.
• Hydraulic Actuators.
• Pneumatic Actuators.
• Electric Actuators.
• Thermal and Magnetic Actuators.
• Mechanical Actuators.
• Supercoiled Polymer Actuators.

What is backdraft damper?

Backdraft dampers are designed for applications where air should only flow in one direction. These dampers always start in the fully closed position. Once air flows in the intended direction, it pushes the blades of the damper into the open position.
