Duct Sound Attenuators

Available in 100 125 150 200 250 315 and 400mm diameter sizes.

Duct sound attenuators.

The simple design relatively low cost and high level of performance flexibility make rectangular silencers a reliable and cost effective choice. All of the silencers have the ability to be stacked into large banks thus accommodating an infinite amount of duct sizes eliminating expensive transitions. In its simplest form a sound attenuator consists of an baffle within the ductwork. 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.

These duct silencers achieve excellent sound attenuation through the attributes of their design. Ruskin noise control can also manufacture the rectangular silencers in any length between 36 and 120. 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.

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 acoustic baffles provide both low and high frequency absorption.

Rectangular silencers are designed to reduce noise in rectangular ductwork while minimizing system pressure drop. 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. Easily installed the duct attenuator is used in the system to absorb sound. Manufactured to join on to rectangular ductwork ruskin noise control rectangular silencers come in a variety of configurations.

They are typically a single formed construction for minimal shell noise. Ruskin has a complete line of acoustical products as well as the experience and knowledge to design products for special conditions. 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.
