Sound Attenuators

Acoustical Louvers

Kinetics Acoustical Louvers are fixed-blade acoustic ventilation louvers designed to reduce equipment noise while allowing intake and exhaust airflow. Economical, effective, and aesthetically suitable for UAE, GCC, and MENA projects, they are ideal where sound control is required but installation space is limited.

Product Description

Kinetics Fixed Blade Acoustical Louvers provide an effective solution for reducing noise from building ventilation, HVAC intake and exhaust systems, generator rooms, pump rooms, acoustic enclosures, and mechanical equipment areas. Designed for maximum sound reduction where depth is limited, these acoustic louvers combine attractive external appearance with practical engineering performance for commercial, industrial, infrastructure, and MEP applications.

Acoustical Louvers are used as part of the intake and exhaust air system of buildings, structures, or equipment to help reduce noise generated by system equipment. Their relatively large surface area compensates for limited depth, making them suitable for projects where conventional deep silencers may not be practical. Kinetics acoustic louver models are available in varying depths, open-area percentages, and blade configurations to support different noise reduction, airflow, and pressure loss requirements.

Available accessories include flanges, bird screen, powder-coat finish, and structural design services for large louver banks and acoustic louver walls. Kinetics Acoustical Louvers are available in galvanized steel type G90, aluminum, stainless steel 304, and stainless steel 316, with powder-coat and baked-enamel finish options.

Kinetics offers several acoustic louver model ranges to suit project-specific sound attenuation and airflow requirements:

KCAC Acoustic Louvers
KCAC models provide 30–40% open area and are available in 12″, 16″, or 24″ thickness. These models offer no line of sight for security applications and are designed for maximum attenuation.

KCPL Acoustic Louvers
KCPL models provide 30–40% open area and are available in 6″, 8″, or 12″ thickness. They feature small vane spacing and are suitable for low-frequency noise control.

KCAL Acoustic Louvers
KCAL models provide 40–50% open area and are available in 6″ or 12″ thickness. They are designed for low pressure drop, lowest cost, and lightweight acoustic ventilation applications.

Model performance data is based on a 48″ x 48″ acoustic louver, with other sizes available. Sound reduction and pressure drop values vary by model, thickness, blade configuration, and airflow velocity. Performance data includes KCAC, KCPL, and KCAL models with insertion loss values across octave bands from 63 Hz to 8000 Hz and pressure drop at 500 fpm.
