Duct Sound Attenuators

Quiet duct rectangular attenuators are suitable for conventional applications including low frequency attenuators having acoustic performance specifically engineered for the 63 hz 125 hz and 250 hz octave bands.

Duct sound attenuators. Easily installed the duct attenuator is used in the system to absorb sound. All of the duct attenuators manufactured by iac acoustics are of the passive design because they do not require mechanical or electrical means to function. These duct silencers achieve excellent sound attenuation through the attributes of their design. In its simplest form a sound attenuator consists of an baffle within the ductwork.

They do their job very simply by providing a trouble free static means for the dissipation of sound energy by converting it into very minute quantities of heat. Solid round nose and bell mouthed entrances increase noise reduction and minimize turbulence. In addition to spiral round and flat oval duct and fittings spot produces rectangular duct and fittings industrial duct acoustical and thermal panels sound attenuators and custom sheet metal work. The simple design relatively low cost and high level of performance flexibility make rectangular silencers a reliable and cost effective choice.

A sound attenuator or duct silencer sound trap or muffler is a noise control acoustical treatment of heating ventilating and air conditioning hvac ductwork designed to reduce transmission of noise through the ductwork either from equipment into occupied spaces in a building or between occupied spaces. Manufactured to join on to rectangular ductwork ruskin noise control rectangular silencers come in a variety of configurations. Rectangular silencers are designed to reduce noise in rectangular ductwork while minimizing system pressure drop. As a result you may choose from a selection of standard or custom engineered duct silencers that will satisfy the requirements of each application.

They are typically a single formed construction for minimal shell noise. Spiral pipe of texas products are manufactured in accordance with the latest smacna ashrae and spida standards. Available in 100 125 150 200 250 315 and 400mm diameter sizes. All of the silencers have the ability to be stacked into large banks thus accommodating an infinite amount of duct sizes eliminating expensive transitions.

A wide range of design and performance options allow rectangular silencers to be. With over 60 years of experience ruskin is recognized as a leading manufacturer of acoustical duct silencers and acoustical thermal modular housings providing top quality and unparalleled performance at an economical price. Sound attenuators for hvac systems kinetics offers the design and engineering assistance to integrate our line of duct silencers sound attenuators into a system solution.
