High-Performance Muffler Tubes
Primarily used in the automotive, on-road and off-road aftermarket; ACS Industries, Inc.’s High-Performance Muffler Tubes take steel wool packing to the next level of exhaust system functionality by combining the acoustic benefits of steel wool with the durability of knitted wire mesh.
ACS’ High-Performance Exhaust Tubes are made by wrapping a layer of steel wool over a knitted wire mesh sock and knitting another sock over that. This layered element is seamless, can be cut to length or shipped in bulk packaging. Because it is based off a knitted sock, ACS’ High-Performance Exhaust Tubes can be made to virtually any ID specifications.

SMC’s silencers and exhaust cleaners offer compact design and easy mounting. SMC’s silencers exhaust in only one direction preventing scattering of mist and noise. In addition, high strength construction prevents damage to threads from a side directional shock. SMC’s exhaust cleaners insure clean plant air and reduction of distributing noise contamination.

The mufflers are elements that are inserted in the conduits where a gas flows. Their job is to reduce as much as possible the transmitted of noise.
A muffler must be chosen using the following criteria of selection.
The sound transmission loss must be the major possible one, not only worldwide, but also spectrally.
Depending on the speed of the gas, there will be demanded a few aerodynamic special conditions.
The materials that compose the muffler will come determined by the temperature and the pressure of the gas. The permanence of the set will depend on the quality of the selected material.
The geometry and dimensions of the muffler will come determined in every case for the available space, the wealth and the loss of load. There are situations in which the volume is very limited, for example in case of the leaks of compressed air.

The PD13 is a premium discharge silencer for blowers operating below transition speed, on which the blower, motor and belt guard are mounted as an integral part of the silencer. The PD13 is designed to facilitate package assembly, thereby reducing labor and the overall costs of assembling smaller blower packages. The design also enables the package to be pretested and shipped to the jobsite without any disassembly. The PD13 incorporates all the benefits of the D13H series silencer seen in Bulletin “D”. The inlet is designed to accept a slip-on flex connector.

The noise suppressors of the Series "R" come used for silenziare the culverts of the gas of drainage of the endothermic motors, the culverts of aspiration and drainage of the compressori of air to pistons or pumps of the empty "type Roots" etc.
The noise that is propaga along the culvert comes convogliato in the noise suppressor.
After to have crossed the reactive section that, thanks to risonatori details to multiple rooms, cancels the impulsive tones to lowland frequency, the gaseous flow crosses the dissipative section and supplies to attenuate the upper-middle frequencies.
|
|
For noise generated by the turbulence of low-speed gas flows and medium-high spectral components.
The noise propagating along the pipe is muffled as it goes through the dissipative section.
The dissipative section is formed by a series of sound-absorbing finned elements arranged concentrically which deliver high sound-deadening performances with limited pressure drops.
|
|
Steam generator outlets (safety valves, start valves),
air compressor breathers (blow-off valves) etc.
The noise propagating along the pipe is channelled into the silencer.
After having crossed the reactive section the gas flow enters the dissipative section which, thanks to special sound-absorbing elements, deadens the medium-high frequencies.

By the application of reciprocating and screw compressors pressure pulsations can be introduced into the discharge line. ESK mufflers reduce these gas pulsations efficiently.
The adjustable discharge line mufflers of the GDX range are
especially suitable for the following application:
• Screw compressor systems
• Capacity controlled compressors
• Individual line arrangement
• Wide evaporating temperature ranges
(ref. mass flow, pressure ratio)
In respect of the adjustment at the inlet- and/or outlet side, an efficient redution of pulsations is reachable.

Copper Mufflers
Parker's Copper Mufflers are used in refrigeration and air conditioning systems to provide noise attentuation associated with pressure pulses from the compressor. The muffler is usually mounted vertically and flowing downward in the compressor discharge line for efficient oil movement. Internal baffles can be provided for additional dissipation of pressure pulsing.
Application
- Refrigeration and air conditioning systems.
Features and Benefits
- One-piece copper shells are available in 3/4", 1-3/16", 1-5/8" and 2" O.D. sizes to match the system requirements of a unit.
- Sweat connections in a variety of sizes provide for easy installation.
