4、 Specification and model of induced draft fan muffler

1. Induced draft fan muffler, scope of application of induced draft fan muffler
Mainly used for various series of high-pressure centrifugal fans to reduce aerodynamic noise such as inlet and outlet.
The FT type has flange connections at both ends that can be connected in series in pipelines, and a rainproof cap at the other end, which is only suitable for installation at the end of outdoor pipelines and enclosed machine room air intakes.

2. Induced draft fan muffler, structural principle of induced draft fan muffler

This type of induced draft fan muffler is developed based on the principle of sound blocking sheet for noise reduction. This type of muffler has excellent acoustic performance and good aerodynamic performance; The structure is reasonable and easy to install, making it a high-capacity resistive honeycomb muffler. The resistance section adopts a multi chamber resistant rubber straight pipe channel and a cross shaped sound-absorbing sheet form, ensuring sufficient noise reduction in a wide frequency range. Induced draft fan muffler, the structure of the induced draft fan muffler is composed of many parallel unit muffler tubes arranged, and porous sound-absorbing materials are filled between the muffler tubes. In order to reduce the radiation sound caused by the vibration of the shell wall excited by the airflow, reinforcement ribs are set on the shell.
