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.

	Separator Silencer		Equipped with features to separate and remove liquids such as water from the flow of the gas or air.
	Spark Arrestor		Spark arrestor silencers are typically chamber design, and designed to trap hot carbon and soot particles. Often used in combustion exhaust applications to minimize danger and maintain air quality.
	Custom Design		Silencer may be customized, modified, or engineered for special applications or design considerations.
	Other / Specialized		Unlisted special design or features.
	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.

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.

Physical Specifications


	Inlet Size		Nominal fitting size or diameter of inlet port.
	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.

	Outlet Size		Nominal fitting size or diameter of outlet or outlet port.
	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.

	Cross Section
	Your choices are...
	Round / Circular		Cylindrical in shape; very common.
	Oval		Oval cross-sections are often used where clearance is a design parameter; a familiar example is a car muffler, where the area is maximized and road clearance is maintained with the oval cross section.
	Square / Rectangular		Square or rectangular cross-section.
	Other		Other unlisted, special, or customized shape.
	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.

	Female Thread		Female threaded port, such as an NPT, BSPT, etc.
	Flange		Mounting flanges typically attach via bolts through a circular bolthole pattern.
	Welded		Silencer or muffler is welded in line.
	Adhesive		Adhesive compound or industrial adhesive tape is used for silencer or muffler attachment.
	Pipe Clamp		Mounts directly onto the pipe, hose, pneumatic line, etc. via a pipe clamp, band clamp, hose clamp, or similar clamping device.
	Other		Other unlisted mounting configurations.
