Sound attenuation

Polairis closed circuit coolers use quiet and energy efficient radial fans, but to reduce noise even further, you can extend your Polairis closed circuit cooler with sound attenuators at the air intake and discharge points.

• Discharge attenuator with vertical baffles
• Intake attenuator with straight baffles

Your local BAC representative can explain the above sound attenuator option in more detail and provide you with sound pressure and sound power data.
