Air outlet muffler for fan

One: Overview of Exhaust Muffler for Fan Export

Noise suppressor for fan outlet is mainly used for reducing intake and exhaust noise of Roots series and axial flow fans, and can also be applied for noise reduction of exhaust ducts and other high-pressure fans. The noise reduction level is 15-30dB(A), with less than 500Pa pressure loss.

Fan exhaust silencers are mainly used to reduce noise at the fan outlet, typically featuring a circular structure and available in single-chamber and double-chamber designs. The ZFD single-chamber model has a noise reduction of 15-20dB(A), while the ZFS double-chamber model offers 20-25dB(A). All cross-sectional dimensions are in accordance with national standards for air ducts. Micro-perforated plates are made of stainless steel or aluminum alloy.

Section 2: Exhaust Muffler Specifications and Models for Fans

The exhaust silencer for fans is mainly used for various series of high-pressure centrifugal blowers to reduce aerodynamic noise at the inlet and outlet air ports.

The FG type has flange connections on both ends, allowing it to be串联 in pipelines. The other end features a rainproof cap, suitable only for outdoor pipeline ends and the air intake of enclosed machine rooms.

The FG type centrifugal fan exhaust silencer is designed based on the sound-absorbing principle of sound-deadening plates. This type of silencer boasts excellent acoustic performance and good aerodynamic performance; its structure is reasonable, easy to install, and is a high airflow resistive honeycomb silencer. The resistive section utilizes multi-chamber resistive straight pipe channels and cross-shaped sound-absorbing plates, ensuring sufficient sound absorption over a wide frequency range. The structure of the exhaust silencer consists of many parallel unit silencing tubes filled with porous sound-absorbing material. To reduce radiated sound caused by airflow-induced shell wall vibration, reinforcing ribs are set on the outer shell.
