Low Band SonaTraps
The Low Band SonaTrap provides the
greatest attenuation in the lower
frequencies, therefore, shorter and
less costly attenuators may be
incorporated when lower
frequencies are dominating.

Packless
The packless silencer, a broad band
tuned silencer, provides attenuation in
lower frequencies without the use of
acoustical fill. The dynamic insertion
loss ratios make them an excellent
selection for hospital/clean room
applications where foreign particles
from conventional silencers may
enter the air stream.

ElbowTraps
The ElbowTrap Silencers are
acoustically engineered with
an aerodynamic design to attain
maximum attenuation and to minimize
static pressure drop. Built as a turning
vane, the ElbowTrap is an alternative
to the standard trap and helps
maintain stabilized air flow.

Acoustical Diffuser Cones
Designed for installation on the inlet
and/or outlet of vane axial-type fans,
the Acoustical Diffuser Cone provides
quality acoustic and aerodynamic
performance. The ADC can reduce
system pressure drop if used in
place of a standard trap due to
it's high efficiency static regain.

SonaVents
SonaVents provide a convenient and
economical method of venting air from
the fan room to a corridor or another
room. Available for installations where
environmental conditions are
maintained, SonaVents are also used
in areas where privacy and security are
essential, but a continuous flow of
fresh air is mandatory. SonaVents are
manufactured for a majority of design
applications and can be customized
for specific acoustical problems.

RA SonaTraps
The SonaTrap Model RA is tested and
manufactured for return air ventilation
grilles in offices, conference rooms,
theaters, hotels, libraries and sound
studios. The slim and compact shape
may be used for small space
requirements, or units may be
combined to suit individual needs.

BT SonaTubes
The SonaTube Model BT serves in
controlling fan noise as a unit, which
eliminates the need for costly duct
lining necessary for high pressure air
flow systems. The BT is adaptable to
any existing system, can be included
in new construction and is available
in custom designs.

STC SonaTraps
Acoustically created to achieve high
attenuation and low pressure drop,
the STC rated SonaTrap features high
performance, quality construction and
economic value. The STC system
rates discharge and radiated noise
(breakout) levels, and is applied to
products when sound control is of
great importance.

Sound Panels
Acoustical/thermal panels are used
for both commercial and industrial
applications. Commercially, panels
are used when larger air handling
units are required to be field erected.
To prevent noise pollution in industrial
environments, panels help meet noise
codes and serve as barriers between
the noise source and receiver.

SonaGuard Sound Rooms
SonaGuard enclosures are designed
for suppressing noise of fans, turbines,
machine rooms, industrial equipment
and audiometric rooms. Available in
a variety of materials, the SonaGuard
enclosure is self-sustaining as a unit
anchored to flooring, or may be
installed with curbing.

Sound Door
The solid 18 gauge, galvanized steel
door acts as a compression seal for
assembled acoustical housing units.
With a standard thickness of two or
four inches, the door can be custom
designed to meet requirements in
accordance with the density of it's
panels, and can be outfitted with
a tempered glass, double paned
window for visual safety.

SonaLouvers
Constructed of galvanized steel,
stainless steel or aluminum, the
SonaLouver is designed to permit
the flow of air as well as providing a
practical solution to reduction of fan
noise emanating from air intakes
and exhausts.
