Circular Sound Attenuators

DESCRIPTION

• Circular silencer construction provides maximum acoustical performance, while minimizing system pressure drop even at high velocities. Desired aerodynamic performance is achieved by avoiding the need for square to round reducers that will increase the pressure drop.
• Sturdy construction and high noise absorbing capacity to obtain required insertion loss without compromising performance. Manufactured to ensure long and maintenance free service.
• Centre splitter (Pod) are radiused at both ends to minimize self generated noise and pressure loss.
• Full width splitter in the middle and half width side splitters at the circumference.
• Casing construction with lock formed seams meet SMACNA standards thus providing excellent strength and rigidity. Thoroughly sealed to prevent air leakage.
• Slip connection on both ends in compliance with DW144 standards.
• Acoustic infill media is of superior quality non combustible & have fungi resistant characteristics meeting the requirements of EN ISO 1182 and ASTM C665 respectively. It has excellent noise reduction coefficient characteristics with an additional qualification of being biologically inert.
