The air silencer (Fig. 1) is attached to the intake side of the blower housing to reduce the sound level of the air entering the blower.
A perforated sheet metal partition divides the silencer into two sections. The engine side of the partition and the outer shell forms an air duct the entire length of the silencer. Air enters this duct from both ends and flows to the blower intake opening at the center. The area between the partition and the outer side of the silencer is filled with sound absorbent, flame-proof Felted cotton waste.
An air intake (blower) screen is used between the air silencer and the blower housing to prevent foreign objects from entering the blower
