micro-slit muffler
The micro-slit plate silencer is an air noise control device used in ventilation and air conditioning systems, clean rooms, hospital purification projects, laboratories, pharmaceutical workshops, electronic factories and industrial ventilation systems. It is mainly used to reduce the noise generated during the operation of fans, air ducts and airflow.

The product adopts a micro-slit plate sound-absorbing structure, and achieves the noise reduction effect of the ventilation system through reasonable panel slits, cavity structure and air flow channel design. Compared with ordinary filled mufflers, micro-slit plate mufflers can be designed according to project requirements into a structure that is fiber-free, easy to clean, and difficult to accumulate dust. It is more suitable for use in places that require air cleanliness and maintenance convenience. Products can be customized according to customer air volume, wind speed, noise control objectives, installation space and system resistance requirements to meet the needs of different HVAC and purification ventilation projects.

Why choose micro-slit plate silencer

In hospitals, clean rooms, laboratories and industrial ventilation systems, fan operating noise, air duct sound transmission and high-speed airflow noise will affect the comfort of the indoor environment and the quality of equipment operation. If the internal materials of ordinary mufflers are not suitable for clean environments, there may be problems such as dust accumulation, fiber shedding, difficulty in cleaning, or inconvenient maintenance.

The micro-slit plate muffler adopts a plate-type muffler structure, with a clean appearance and stable structure. It can reduce noise while meeting the requirements of the ventilation system for cleanliness, durability and ease of maintenance. It is suitable for use in hospital purification projects, clean rooms, laboratories, pharmaceutical electronics factories and other scenarios that have high requirements for noise control, air cleanliness and long-term operation stability.


Main features

Micro-slit plate sound-absorbing structure

Using a micro-slit plate and cavity combination structure, it reduces the noise of the ventilation system through sound wave absorption and impedance, and is suitable for noise reduction in air duct systems.

Fiber-free structure optional

It can be designed as a fiber-free sound-absorbing structure according to the requirements of clean environment, reducing fiber shedding and cleaning and maintenance problems that may be caused by traditional sound-absorbing materials.

Suitable for clean ventilation systems

Suitable for ventilation systems that require air cleanliness, such as hospital purification projects, clean rooms, laboratories, pharmaceutical workshops and electronic factories.

Reasonable ventilation resistance

The internal air flow channel is reasonably designed to achieve the sound attenuation effect while controlling the system resistance and reducing the impact on the air volume and operating efficiency of the air conditioning system.

The surface is smooth and easy to clean and maintain

The surface of the micro-slit board is clean and not easy to accumulate dust, making it easy for daily inspection, cleaning and maintenance. It is suitable for long-term installation in clean ventilation systems.

Stable and durable structure

The shell and internal structure are made of high-quality metal materials, with high overall strength and suitable for long-term operation of ventilation, air conditioning and industrial ventilation systems.

Flexible material selection

It can be made of galvanized steel plate, stainless steel, aluminum alloy or other materials to meet the needs of general ventilation, clean environment, anti-corrosion environment and special engineering projects.

Support non-standard customization

It can be customized according to customer drawings, air duct size, air volume parameters, noise control requirements and on-site installation space, and is suitable for use in different engineering projects.
