Silencers
Ventilation system silencers, also known as duct silencers or noise attenuators, are components used to reduce the noise generated by air movement within ductwork. They are designed to minimize the transmission of sound from the ventilation system to the surrounding environment, helping to create a quieter and more comfortable indoor space.
There are different models available for use in clean air and greasy air environments. Silencers used in greasy air environments contain a Melinex film separator, which helps to keep the insulation material away from the grease. This process is crucial for preventing fires and extending the life of the silencer.
Furthermore, there are models with and without pot, available in different lengths. Selecting the most suitable silencer depends on the desired reduction in sound decibels and the pressure losses in the system.
Silencers work by absorbing and dissipating the sound energy produced by the airflow within the ductwork. They typically consist of an outer casing, which encloses sound-absorbing materials such as foam, fiberglass, or mineral wool, and internal baffles or chambers that help to redirect and attenuate the sound waves.
When air passes through the silencer, the sound waves encounter the sound-absorbing materials, which absorb the energy of the sound waves and convert it into heat. This reduces the intensity of the sound before it exits the silencer and enters the surrounding space.
Ventilation system silencers are commonly used in HVAC systems, particularly in commercial and industrial settings where noise control is important. They can be installed in supply or return air ducts, exhaust systems, and fan installations to reduce the noise produced by air handling units, fans, and other equipment.
The selection and design of ventilation system silencers depend on factors such as the airflow rate, duct size, noise criteria, and space constraints.
Proper sizing and placement of silencers are essential to ensure effective noise reduction without impeding airflow or causing pressure drops in the ventilation system.
Inoxos selects and utilizes both its own manufactured silencers and those from collaborative brands to ensure the most appropriate choice. Since we produce our own, we can manufacture silencers in the most complex shapes.
