Air Control Equipment

Air-control equipment is part of the systems for guiding and distributing air, which plays a very important role in the quality of the inlet and outlet air in various spaces. Industrial dampers and silencers are among the most important airflow-control equipment in the non-industrial sector; their main application is in office buildings, commercial complexes, hotels, and hospitals. In the industrial sector, in addition to the quality of the inlet air to various spaces, controlling the airflow and also the quality of the outlet air from various devices is of great importance. One of the most heavily used spaces for industrial dampers is the metro and rail-transport systems. The high traffic of people at various hours of the day and night creates very high sensitivity in this sector. One of the greatest hazards the metro faces is the need to direct and exhaust smoke caused by fire and to control its stoppage in various spaces. This is achieved by fire-resistant and air-tight dampers that prevent the passage of smoke. Another important challenge in the metro is the need to reduce the noise of the airflow to the permitted level, which is achieved by large-dimension silencers. Types of dampers Control and isolation dampers Rectangular dampers and round dampers are designed to control and shut off airflow in air-transfer systems. The flexibility in the design of these models makes a wide range of configurations, options, accessories, and actuators possible. Isolation dampers are designed for applications in which the amount of leakage is important. These dampers have the highest level of air-tightness. One-way dampers These dampers are designed to prevent the movement of air in an undesirable direction. In their design, external weights are incorporated that ensure the movement of air in the desired direction and prevent the movement of air in the opposite direction. Pressure-relief dampers These dampers are designed to prevent excessive pressure buildup inside systems. When obtaining these dampers, a number is given as the pressure at which the damper begins to open. When the system pressure exceeds the stated number, the dampers open and the excess pressure is discharged. These dampers, like one-way dampers, have external weights, and the damper prevents the movement of passing air in the opposite direction. Tunnel-passage dampers These are designed as a special solution for enclosed transport systems such as road tunnels and rail transport. The above is merely an excerpt from the book "Industrial Silencers and Dampers ", which has been published by Hak Publications and is available.
