Type / Application
           
   Your choices are...         
   Vent / Blowdown Silencer       Silencer designation for rapid exhaust or venting applications, a.k.a. "blowoff" silencers. 
   Engine Silencer       Used for noise reduction on industrial engines.  Both inlet and outlet silencers may be used; some products may be used for either inlet or outlet. 
   Blower / Fan Silencer       Silencer designed for the intake or outlet of a fan or blower; can contain air filters and other features. 
   Compressor Silencer       Specifically designed for use on air or gas compressors. 
   Pressure Relief Valve Silencer       Designed for use with backpressure or pressure relief valves to attenuate the noise associated with relief blowoffs. 
   Turbine Silencer       Intended for noise attenuation on the inlet and/or outlet port of turbines, typically gas turbines. 
   Vacuum Pump Silencer       Specifically designed for noise attenuation at the inlet and/or outlet of a vacuum pump.  
   Chimney Silencer       Chimney silencers are designed specifically for combustion exhaust, such as for industrial boilers, ovens, and furnaces. 
   Pneumatic Muffler       Designed for attachment to exhaust ports of air cylinders, solenoid valves, or other pneumatic components.  Typically used to soften the noise and his of the air exhaust, and sometimes provides a small measure of exhaust flow control. 
   Automotive Muffler       Familiar type of muffler, designed for used on cars, trucks, motorcycles, industrial vehicles, etc. 
   Other       Other unlisted, specialized, or proprietary type of silencer or muffler.

Performance Specifications
   Noise Attenuation:       Noise reduction or attenuation, measured in deciBels.  Silencers and mufflers typically have performance curves across the audible frequency range; for simplicity, the number given here is the maximum or nominal manufacturer rating. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Pressure Rating       Maximum rated air or gas pressure for the silencer. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Maximum Flow Rating       Maximum airflow or gas flow rating the silencer can handle and still meet performance specifications. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Silencer / Muffler Design       
   Your choices are...         
   Reactive / Diffuser       Reactive silencer designs utilize complex passages and/or chambers to attenuate noise associated with air or gas passage.  Advanced acoustic and mechanical analysis and design techniques are used to optimize noise attenuation while maintaining other application requirements, such as pressure drop, airflow, and size. 
   Absorptive       Absorptive silencers incorporate sound-deadening materials, fabrics, and compounds to absorb the noise energy of the air or gas flow. 
   Hybrid       Hybrid designs use both reactive and absorptive design elements, combining both airflow path management and acoustical materials to reduce noise. 
   Active Noise Cancellation       Active noise cancellation uses sound sensors to characterize the sound profile, and then actively cancels it with speakers set to produce sound 180° out of phase with the airflow noise. 
   Other       Unlisted, specialized, or proprietary silencer or muffler design. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
