| IAC
America offers the broadest range of silencers/louvers in the industry. All
of IACs silencers were developed in response to specific requirements from
acoustical consultants, consulting engineers, owners, and contractors. Having
been pre-tested for performance, they provide the most economical choices for
solving the wide variety of noise control problems encountered in HVAC engineering. -
Quiet-Duct Ultra/Low For conventional
applications where guaranteed performance is required down to 31.5 Hz, including
finer resolution of one-third-octave-band data for applications requiring full
octave band performance to match specific sound sources. -
Quiet-Duct
Ultra/Green A 100% environmentally friendly attenuation solution.
Silence is achieved through the use of recycled acoustic fill material. Ideal
for any clean and green application. -
Quiet-Duct Ultra/ZAPD
For applications in which acoustic attenuation is required and no allowance
can be made for pressure loss. A Zero-Added-Pressure-Drop silencer is ideal of
high velocity systems or systems that have little or no room for additional pressure
drop. -
Quiet-Duct Commercial Series For conventional applications
including low frequency. Silencers are specifically engineered to enhance insertion
loss in the 63 Hz, 125 Hz, and 250 Hz octave bands. -
Clean-Flow
Rectangular Silencers For systems requiring a higher degree of cleanliness
and hygiene such as in hospitals or clean rooms. Linings on the fill material
guard against erosion of particulate matter into the air-stream. Specific internal
construction features protect the lining against chafing or premature failure
and are necessary to maintain the rated aero-acoustic performance. -
Conic-Flow Tubular Silencers For silencer applications including low
frequency. Silencers are specifically engineered to enhance insertion loss in
the 63 Hz, 125 Hz, and 250 Hz octave bands. -
D-Duct Acoustic
Diffuser Silencers For use on axial-fan systems. The combined interior
diffuser cone and exterior square jacket casing make these units aerodynamic-regain
devices as well as silencers. -
Ultra-Pals Rectangular Packless
Silencers The ultimate solution for ultra-clean environments and corrosive/flammable
environments. The complete absence of fill makes Ultra-Pals Rectangular -
Packless Silencers ideally suited for any application where particulate matter
or fiber erosion from conventional fill materials could contaminate the air/gas
streams. The complete absence of fill combined with ease of cleaning and draining,
makes Ultra-Pals Silencers ideal in corrosive/flammable environments and
for facilities handling gasoline, grease, solvents, and other hazardous materials.
Ultra-Pals Tubular Packless Silencers
For small-diameter circular duct systems such as fume hoods. Additionally, the
packless design of these units makes them equally applicable to the types of systems
mentioned for the Rectangular Ultra-Pals Silencers. Acoustic
Louvers Twelve inch deep model R and model LP
louvers allow for ventilation while reducing noise transmission from building
machine rooms. Four inch and six inch Slimshield models are compact for
use in walls, doors, or equipment enclosures where airflow is required.
IAC has more than five decades of experience in the
design and manufacture of silencers for jet engines, gas turbines, forced draft
fans and air handling systems. The result is an extensive range of standard silencer
configurations incorporating innovative design and manufacturing features with
performance certified in IACs Aero-Acoustic NVLAP-Certified Laboratory.
Performance ratings for both Dynamic Insertion Loss and Aerodynamic Pressure
Drop for all Power-Flow Silencer designs have been certified in accordance with
ASTM E477 and applicable sections of ISO 7235:1991 and British Standard 4718-1971
in our full-scale wind tunnel and corroborated by independent laboratories. Some
typical applications for Power-Flow Silencers include: - Gas

Power-Flow ACoustic FIlter (ACFI) Tuned Dissipative Silencers
IAC
ACFI Silencers are designed to provide noise control for induced draft fans in
power plants, ventilation system in steel mills, coal mines, aluminum reduction
facilities, and other processes that involve gas streams which often contain appreciable
amounts of moist particulate which can quickly clog and render conventional parallel
baffle absorptive silencers ineffective. Take advantage of IACs know-how
the
most extensive in the noise control industry. Special silencer configurations
are available to satisfy the most stringent criteria. Click
