Industrial Fan Silencers
Fans are found in many applications, including industrial, HVAC and processing functions. However, in any mechanical device that require components to rotate at high speeds, noise can become problematic. Throughout Universal AET’s long history, we have adapted existing products and developed new ones to address this age-old problem.
Primary air fans, forced draft fans and induced draft fans generally require some form of acoustical treatment. Most applications require inlet and/or outlet silencers to meet OSHA and other noise requirements. For continuous exposure, a maximum of 90 dBA is generally specified to avoid hearing damage. When conversation near the fan is desired, levels of 80 dBA and below are often needed.
Cost-Effective Silencers for Every Fan Type
Universal AET designs and manufactures a complete line of silencers for application on all fan types. Computer-enhanced technology developed for fan, turbine and other air-moving equipment enables us to offer a cost-effective solution for every fan silencing application. Each of the three designs in this section has unique advantages over the others depending upon the application, pressure drop and space utilization. The catalog covers standard models and sizes, and provides basic information to evaluate the merits of the individual designs for your application. Special configurations, materials, higher temperatures and sizes are available upon request.
AFS Series Absorptive/Reactive
The AFS series fan silencer combines a reactive and absorptive chamber design that reflects acoustic energy and dissipates it with absorptive pack material. Constructed from plate and sheet steel in an all-welded, straight-through flow path design, the AFS series is suitable for most applications on the inlet and discharge of centrifugal or axial blowers, especially when low pressure drop is required. The standard AFS silencer is suitable for temperatures up to 325°F.
Acousti-Tube Absorptive/Tubular Flow
The modular, compact, lightweight Acousti-Tube silencer knocks out high-frequency noise while minimizing pressure drop. The Acousti-Tube silencer is available in standard cross-sections and lengths, which cover a wide range of product applications and are economical solutions to noise problems. The silencer’s modular design allows customization for non-standard configurations without increased pressure loss or loss of acoustic performance.
Acousti-Vane Absorptive/Parallel Baffle
The Acousti-Vane silencer comes in standard cross-sections and lengths that cover a wide range of applications and provide economical solutions to a broad range of noise conditions. Standard units can be adapted for use in non-standard or application-specific configurations.
