MUFFLERS (OR PNEUMATIC SILENCERS)

1. What are Mufflers ?

Function: The function of muffler (also known as pneumatic exhaust silencer) is to control the noise caused by a rapidly exhausting air-stream flowing into the atmosphere.

Noise created by air exhausting from an air system not only cause nervous tension and dissatisfaction among the operators, but also results in mental fatigue, lack of concentration, and inefficiency. This exhaust noises can be greatly reduced by installing a muffler at each pneumatic exhaust port.

2. Construction and Operation

The construction and operation of a typical pneumatic silencer is illustrated in Fig.11.13(a)


As shown in Fig.11.13 (a), the exhaust air stream enters one end, and passes out the another end after passing through a series of baffles. The baffle tubes are perforated with a large number of small holes. The outer shell acts as a barrier and helps guide the stream toward the exit to the atmosphere.

3. Graphic Symbol

Fig.11.13(b) shows the graphic symbol for a muffler.
