Acoustics Reduce Fittings Mufflers Noice Reductive Device

Product DescriptionHysun Duct-wrapped Silencers .
Hysun Duct-wrapped Silencers are used to reduce the noise generated by pipeline vibrations and fluids in gas and liquid pipelines which cause the whistling sound by pressure changes at the reducer union, elbow, and valve.
this product is used in large commercial, institutional and industrial buildings to provide treated air to the occupants and to remove exhaust air and fumes from the buildings. This can result in duct noise levels which exceed established standards and regulations. Inline duct silencers provide an effective means of reducing this noise.
Typical duct silencer applications:
Supply and return ductwork
Fan plenums and air handling units
Terminal boxes and mixing boxes
Fume and smoke exhaust
Alternative to acoustically lined ductsDetailed ImagesNoise Reduction benefits
Sizes custom designed to match the dimensions of connecting ductwork

No transitions or plenums required

Aerodynamic nose design and tapered tails to minimize pressure drop
Eleven (11) baffle configurations for more precise matching of duct silencers to applications.
Duct silencer length, open area, and configuration are all determined by the noise control requirements and the design of the duct system. Our team is experienced in evaluating factors such as air volume and velocity, and will engineer duct silencer solutions to achieve all of the performance specifications on your project.Packing & DeliveryProduct FeatureInstallation
1. Installed on the outside of the pipeline, it also plays the role of vibration reduction, heat preservation and anti-corrosion while reducing noise..Fixed
2. The muffler is fixed by a lock, which is convenient to install and has no effect on the conveying operation of the pipeline.Easy Disassemble
3. It is convenient to disassemble. When repairing the pipeline, it is only necessary to remove the muffler package at the pipeline where the problem is solved. After the pipeline repair is completed, the muffler can be installed immediately, which has no effect on the overall appearance.
