Silencers are absorptive units designed & fabricated to provide predictable, durable noise control performance for applications such as HVAC system noise, fan noise, plenums, mechanical draft fans, gas turbines, cooling towers and equipment rooms. ArtUSA Silencers and Attenuators allow a large volume of air flow with minimal aerodynamic restrictions, resulting in effective noise insertion losses with static pressure drops of less than 1" w.g. We can ship or install both standard & custom designed units.

INDUSTRIAL SILENCERS
Specifications

1.0 General

Industrial absorptive silencers as shown on the contract drawings or as tabulated shall be installed to reduce sound transmission to occupied spaces. Silencers shall be as specified by customer and manufactured by Kinetics Noise Control - ArtUSA Industries Products Group.  Any changes to this specification must be approved by the customer and/or engineer and ArtUSA prior to manufacture.

2.0 Construction

Silencer shall be of the sizes and lengths shown, shall be modular, and shall consist of galvanized, carbon, aluminum or stainless steel outer and interior partitions. Silencers shall be custom designed and manufactured to remain airtight at the specified pressures.

Acoustic fill material shall be glass fiber of a density calculated to provide the published acoustical and aerodynamic performance. Fill material shall be class 1, as tested in accordance with ASTM E-84.

3.0 Acoustic Performance & Certification

Silencers shall exhibit a dynamic insertion loss not less than that shown in the specifications, pressure drop under design airflow shall not exceed that shown, as determined by the manufacturer.

Submittals shall be supplied with Dynamic Insertion Loss, Self Noise Power Levels and Aerodynamic Performance for forward (supply air) and reverse (return air) flow conditions.

ArtUSA Silencers can also be constructed for over-sized and custom applications. These silencers provide extra durability in extreme environments, enable removable baffles (for cleaning or maintenance) & offer additional protection to the absorptive fill from contaminants in the airflow. Construction can range from 18 gauge to 10 gauge outer shells using any material from carbon steel, stainless steel or aluminum.

Silencers impede the propagation of airborne noise through ductwork and building openings as well as enclosures and HVAC equipment. Although all silencers accomplish this to varying degrees, many do so by compromising system performance. ArtUSA however, offers the design and engineering assistance to integrate our industrial silencers into a system solution. As a result our silencers are custom engineered to satisfy the requirements of each application. Prime candidates for noise control measures are openings into and out of noisy environments. This includes the ventilation of buildings, enclosures, and equipment rooms. Integration of noise control measures, such as silencers and louvers, into the system design requires careful consideration of space constraints, fan selection and aerodynamic pressure losses
