  • DN series efficient silencer

    At present, ship air conditioning and ventilation systems mostly use centralized air supply all air systems to achieve cabin air environment control. There are two main sources of noise: one is the noise generated by the operation of (combination) air conditioners, ventilators, and other equipment; The second is the regenerative noise generated by the airflow in the air ducts and equipment, including the noise generated by the air ducts and air vents. Therefore, noise control needs to be approached from two aspects: on the one hand, optimizing system design to reduce noise from the sound source; On the other hand, measures such as sound absorption and noise reduction are taken to control the propagation of noise, which to some extent attenuates the noise to a lower value. In the air conditioning and ventilation system, the air vents require airflow to pass through. In this case, vibration isolation and noise reduction schemes are no longer sufficient at certain locations. In this case, we usually install silencers on the ventilation ducts to reduce noise. Josun air conditioner is a specialized high-efficiency muffler developed according to the GB/T 25516-2010 standard for various ventilation systems. It has the characteristics of good noise reduction effect, low air resistance loss, and easy installation. Widely used in various equipment rooms, garages, ships, and offshore platforms.

Model Description:

“DN”:  muffler

1600 "inner diameter size

Composition: The muffler consists of a muffler shell and a muffler unit, with a muffler unit channel in the middle. The muffler unit channel is made of muffler orifice plate, ultra-fine fiberglass cotton, and fiberglass hole cloth.

Product Features:

The DN series efficient silencer is a silencing device that attenuates or prevents sound propagation while allowing airflow to pass through. With the sound absorption effect of sound-absorbing materials or structures, the noise propagating along the pipeline is attenuated with increasing distance, and the sound energy is absorbed and converted into heat energy, achieving the purpose of silencing and reducing airflow noise in machinery.

The DN series muffler is a ventilation duct muffler, which is of the acoustic resistant flow type; It has a sound-absorbing and noise reducing effect on high and medium frequency noise, suitable for various cabins.

Product advantages:

Our company's efficient silencer can be made into circular or square shapes, which can be used in conjunction with fans. It has good ventilation flow, low resistance, and good noise reduction effect. It can be installed vertically or horizontally. The silencing unit has ideal silencing effect over a wide frequency range, good aerodynamic characteristics, and special design for the flow guide and orifice plate, resulting in minimal resistance loss.


Basic parameters:

  • DN300-600 noise reduction volume: 4-6 dB (A)

  • DN700-1000 noise reduction volume: 6-8 dB (A)

  • DN1200-1600 noise reduction volume: 8-10 dB (A)

  • The shell is made of ordinary steel plate rolled, or stainless steel or other materials can be used according to user requirements;

  • The sound-absorbing board is made by stamping and rolling ordinary steel plates, and can also be made of materials such as stainless steel according to user requirements;

  • The sound-absorbing cotton is made of ultra-fine fiberglass cotton

  • Fiberglass cloth is wrapped around the sound-absorbing cotton, which is conducive to fixing the sound-absorbing cotton and preventing it from scattering.


Application scenarios:

Widely used in various types of passenger ships, cargo ships, warships, and offshore oil platforms.
