The fans that move air
through modern HVAC systems are noise generators. The ductwork
carrying conditioned air to occupied spaces throughout the
building can often act similar to the old fashion “speaking
tubes”that can conduct intrusive and annoying fan noise
to occupied spaces. This can often result in annoying or intolerable
noise levels in offices, conference rooms, classrooms and
auditoriums, etc.
One solution is place one
or more duct silencers between the fan and the occupied spaces.
While reducing objectionable fan noise, duct silencers can
also reduce cross-talk transmitted from one space to another
through the ducts to insure office privacy.
SILENT-MOD
duct silencers are available in a wide assortment of geometries,
models, and lengths. This is to accommodate duct shape. Pressure
drop vs. airflow and noise reduction.
SILENT-MOD
silencer shells are
fabricated from 22-18 gauge galvanized steel for superior
strength and maximum sound transmission reduction through
side walls. No flimsy 26 or 24 gauge material that vibrates
in the airstream.
Let our engineering department
help you with your silencers needs.
