Kinetics Circular Duct Silencers are UAE-made sound attenuators engineered to reduce airborne noise in round HVAC and ventilation duct systems. Suitable for fan inlets and discharges, air handling units, cooling towers and other mechanical air systems, they help consultants and contractors achieve the required acoustic performance while controlling pressure drop and regenerated noise.
Each circular silencer is selected according to duct diameter, airflow, target insertion loss, available installation length and project construction requirements. Straight dissipative, acoustic-bullet and space-efficient configurations can be evaluated according to the application.
Kinetics Group supports acoustic consultants, MEP contractors, developers and industrial clients across the UAE, Middle East and MENA with engineered product selection, local fabrication and project-specific technical support. Submit the duct size, airflow, octave-band noise data and allowable pressure drop to receive a suitable circular silencer recommendation.
Engineered for Performance.
Kinetics Circular Silencers are high-performance cylindrical HVAC sound attenuators for round duct systems. They reduce airborne noise while supporting efficient airflow and controlled pressure drop.
Kinetics manufactures these circular duct silencers in the UAE for commercial, institutional, and industrial building-services applications. They help control fan noise, airflow noise, and mechanical ventilation noise in HVAC and MEP systems.
Each circular silencer uses a cylindrical, pressure-tight casing and a streamlined acoustic core baffle. Kinetics packs the acoustic section with continuous-strand fiberglass under compression. A minimum 22 ga. or 0.85 mm galvanized perforated-steel liner protects the acoustic absorption media.
Kinetics centers the absorptive core baffle inside the casing. In addition, a spun head at the inlet reduces entrance pressure loss. The tapered tail then helps balance insertion loss with pressure-drop performance.
This aerodynamic design allows the silencer to reduce duct-borne noise without creating unnecessary airflow resistance.
Kinetics offers 10 standard circular silencer types in three standard lengths. Therefore, engineers can select from 30 standard design options for different acoustic and airflow requirements.
The standard and custom configurations include:
Kinetics also develops non-standard variations for special HVAC, MEP, and acoustic design conditions.
As a result, acoustic consultants, MEP engineers, and contractors can select a suitable configuration based on:
Kinetics fabricates standard circular silencers from G90 galvanized steel.
For diameters from 12 in. to 24 in., or 305 mm to 610 mm, Kinetics uses a minimum casing thickness of 22 ga. or 0.85 mm.
For diameters greater than 24 in. or 610 mm, Kinetics uses a minimum casing thickness of 18 ga. or 1.31 mm.
In addition, every circular silencer maintains airtight performance at a pressure differential of 10 in. Wg.
Kinetics provides insertion-loss data for standard circular silencer construction. This data helps engineers evaluate acoustic performance across different silencer sizes, lengths, and configurations.
Longer silencers generally provide higher insertion loss. However, the additional length also increases pressure drop. Engineers must therefore balance sound attenuation with system airflow requirements.
Circular silencers with a sound-absorbing bullet can achieve higher insertion loss. The bullet reduces the open face area and increases acoustic absorption. However, the smaller open area also constricts airflow and increases pressure drop.
Kinetics presents pressure-drop data for silencers installed in straight duct sections. The published data assumes that neither silencer end sits close to a bend, elbow, or transition. Nearby fittings can change airflow conditions and affect actual pressure loss.
For special acoustic-media coverings, customers should contact the local Kinetics representative. Engineers may also use the Kinetics web-based silencer selection program.
Special media-protection options include:
These coverings fit between the acoustic media and the perforated interior or bullet shells.
Kinetics offers a wide range of construction and installation options, including:
These options help consultants and contractors meet project-specific requirements for corrosion resistance, installation, maintenance, and equipment support.
Kinetics provides a web-based silencer duct-system and acoustical-analysis program for engineers worldwide.
The program helps engineers evaluate:
For accurate selection, engineers should provide the duct diameter, airflow volume, airflow velocity, octave-band sound data, required insertion loss, allowable pressure drop, available installation length, and construction requirements.
Independent laboratories test Kinetics silencers in an NVLAP-accredited laboratory. The testing follows ASTM E477-06a and AMCA 1011-03 procedures.
This independent testing supports consultant specifications, acoustic calculations, technical submittals, and project documentation requirements.
Kinetics combines UAE manufacturing with tested acoustic performance and flexible engineering options. The broad range of standard and custom designs helps consultants, contractors, and project teams control HVAC noise while managing airflow and pressure drop.
