EIW - Fan Silencer - Brochure

Industrial fan installations, small or large, produce noise. This fan noise is one of the most predominant noise sources in an industrial plant. The magnitude and intensity of noise will vary depending on fan size, horse power, air flow, type and number of blades, static pressure, rotational speed, etc. Fans normally deliver a large volume of air at relatively low static pressures usually measured in inches of water. The rotating action of vanes produce a broad band noise spectrum however, the noise in mid to high frequency range is heard to be louder and requires to be treated for achieving noise control.
