OUR SERVICESVolume Control Dampers are a critical element of any HVAC system.

They function by enhancing the productivity of the HVAC system by increasing the air circulation in the air-conditioning or ventilation systems. Volume Control Dampers, which are typically installed in duct branches, are used to stabilise or constrain air movement in the ducts. To control the flow and pressure of air, these dampers have manual adjusters and mechanised actuators.

An HVAC damper works by providing air to particular zones in the building by installing the damper in those zones. This will not only ensure you get a balanced air flow to that area but also reduces the amount of air flow wasted in the unoccupied areas.

 Volume Control Dampers are manufactured in stainless steel, aluminium and galvanised steel sheets and are commonly used in supply, return and exhaust air Ventilation systems.

 Duct collars are attached to the main duct branches and the plenum system to attach and install straight fitting for ducts. Installation of a duct collar is one of the initial steps in working and planning for a duct system . This plan requires an HVAC knowledge or a detailed overview of the designed duct work as well as the capacity to work in crawl spaces in most cases.

These collar work with either Manual Dampers or Automatic dampers:

Manual Dampers:

The lever of a manual damper is found outside of the air vents or duct valves. Most of the manual dampers are easy to install and have a simple mechanical design to work with and ensure a balanced air flow. They are also more durable and require less maintenance. You need to twist the screws on these dampers to regulate the flow of air.

Compared to the automatic dampers, manual dampers lack the precision of the automatic ones and can cannot be operated remotely

Automatic or Motorized Dampers:

Through automatic dampers you can control the amount of air going to a particular area. These dampers generally use a small motor to control the circulation of air through the valves. Through the information set on the thermostat by the homeowner, the automatic dampers can self-regulate the air and can automatically respond to the changing weather conditions.

The HVAC dampers allow you to change the temperature of a particular room without disrupting the overall temperature of the house.

As it allows for a balanced air flow as well as restricted air flow to unoccupied areas or significantly decreases the energy consumption by the system.

 To guarantee you have a perfectly working operating principle for the duct systems, you must choose the proper damper. This will help in a greater efficiency in the working of the system and will reduce operational costs. The damper dimensions have to be suitable for the estimated airflow volume in any system. The hired technician should be able to choose a size that generates enough velocity (and thus enough pressure drop) to ensure consistent air control, temperature and pressure.
