Know About Combination of Fire Damper and a Smoke Damper

A fire damper is an extremely important device as far as safety from fire is concerned. It has enormous uses in the modern life that should be addressed readily.

Use of a fire damper

A typical damper can be used as either of the following:

1. Static systems

For all HVAC systems that are shut down automatically when there is a fire and also for other air transfer openings in partitions and walls.

2. Dynamic systems

This is for all those HVAC systems that are completely operational in the event of a fire.

3. Combination of fire and smoke dampers

This is for all those locations where both fire dampers and well as smoke dampers are required.

4. The corridor dampers

This is for all those locations in the HVAC systems where an air duct penetrates and/or terminates at the openings of the ceilings of the interior corridors.

Tests for smoke dampers

Any typical smoke damper is subjected to the following tests:

1. The cycling test

The pre- condition of a cycling test is that a smoke damper becomes a damper that is used before other tests can be carried out. It can also continue to function as intended after it is operated mechanically.

2. Temperature test

Before an air leakage test, a smoke damper is subjected to this test. A smoke damper is then positioned in an oven during the cycle of temperature degradation on the cycling test.

3. An operation test

After the completion of the above two test, a smoke damper is then subjected to a routine operation test. This test is performed at an ambient temperature and at a rated airflow and pressure. This test is said to be bi- directional, so that the damper is tested with an air flow from both the directions.

4. The leakage test

At an ambient temperature, a smoke damper is subjected to the leakage test. The leakage amount is measured in this test, and this test shall determine the class of leakage of the smoke damper. This is also a bi- directional test such that the damper is with an air flow from both of the directions. The leakage test is said to be the most important test out of all.

Common features of a fire damper

Below are a few common features that can be noticed in a fire damper:

1. A typical damper has triple V- Groove blades.
2. The dampers have a UL approval for a dual directional airflow.
3. It has a maximum rating of 4" w. g. and 2000 fpm.
4. The failsafe design enables a damper to automatically assume any desired position whenever smoke or fire interrupts an operation airflow.
5. The damper as a construction of galvanized steel that ensures supreme quality and durability.

KAD Air Conditioning is a company that is well known for having a range of fire and smoke dampers. It has also added the combination of fire and smoke damper to its list. This range of fire dampers is used in a particular HVAC duct system. Today’s structures in corporate extremely complex and sophisticated design, infrastructure and location and there are times when there can be a threat of fire. In case a fire gets started, it can cause harm to life, property and valuable efforts. Fire dampers are installed in these structures to provide safety against a fire accident. The company has been doing this fordecades, and this has resulted in a loyal customer base. All dampers and equipment by KAD Air Conditioning are subjected to the latest testing and certification. This ensures that they are of the top most quality and there will not be any faults during their functioning. Dampers are extremely helpful in the long run; be it residential, commercial and industrial properties.
