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.
