Square, Rectangular, or Round
BAM Custom Silencers are traditionally sized to mount directly on the discharge of the fan or to match the dimensions of the ductwork. They are built to suit your application.
Transition pieces can be provided separately or as an integral part on custom units.
Fan companies often use an expanded, or evase, outlet to reduce the velocity of the air as it leaves the fan. We added sound-absorbent media to produce a highly effective silencer that is also "pressure neutral" to the system.
Around the Corner
When limited space is a factor, a BAM around the corner silencer provides the solution. Sound is effectively absorbed as the air is turned 90° - just put one in where an elbow is needed. They're custom-built to fit your duct.
