Acoustic Louvers

ISTIQ Acoustic Louvers are designed to reduce noise passing through ventilation openings while still allowing airflow for mechanical and industrial systems. They are commonly used in generator rooms, acoustic enclosures, plant rooms, compressor rooms, pump rooms, AHU rooms, cooling systems, factories, and other applications where airflow is required, but open ventilation paths can become major points of noise leakage.

Unlike a normal ventilation louver, an acoustic louver must balance noise reduction, airflow, pressure drop, free area, weather protection, durability, and installation details. The internal louver blades are designed with acoustic absorption material and a suitable geometry to reduce sound energy as air passes through the opening. This helps control noise from fans, engines, compressors, generators, and mechanical equipment without fully blocking the ventilation path.

A good acoustic louver cannot be selected by opening size alone. The design should consider airflow rate, face velocity, allowable pressure drop, required noise reduction, rain protection, material selection, corrosion resistance, blade depth, installation position, and whether the louver is used for intake or discharge. If the louver has too much free area, the noise reduction may be limited. If it is too restrictive, the system may suffer from poor ventilation or high pressure drop.

ISTIQ Acoustic Louvers can be integrated with genset room noise control systems, acoustic enclosures, containerized generator systems, plant rooms, ventilation shafts, industrial buildings, and mechanical equipment areas. For better performance, they are often used together with duct silencers, attenuators, acoustic doors, exhaust silencers, wall treatment, or complete acoustic enclosure systems.
