Duct Silencers / Attenuators

Application Notes

Whenever ventilation is required in the enclosed compartment and at the same time noise is to be controlled, installing duct silencers or attenuator are the best way to solve the problem. The silencers permit air to flow through while reduce the noise by absorbing it. In selecting a silencer, a balance between noise attenuations and pressure drop need to be considered carefully.  By using internally developed software, ISTIQ NOISE CONTROL can help to make the right choice quickly and most importantly, accurately.

Introduction

ISTIQ DUCT SILENCER are designed to efficiently reduce noise by generator sets, air handling systems, compressor, blower system and all situations requiring air intake and outlet for these equipments to operate.
A duct silencer should always positioned in the plant room and if possible as close to the noise source as possible. Normally for a single equipment, two units of duct silencers - intake and discharge is required to effectively reduce the noise to a desired level.

Construction

ISTIQ DUCT SILENCER are available in two different models, which basically have two different thicknesses of splitters - 200 mm and 300 mm. The thicker the splitter the better performance at lower frequencies. Each of the models have six length sizes from 900 to 3000 mm. The cross sectional area has no limited size. 

ISTIQ DUCT SILENCER will be supplied in sections whenever the silencer dimension exceeded 2100W x 2100H x 2100mmL. This will make the transportation and installation easier. The assembly of sectionalized silencers to be done at site.
