Induced draft fan noise is too high, causing discomfort for employees, increasing environmental compliance pressure, and potentially leading to premature equipment failure.
In fact, noise reduction doesn’t require major reconstruction—four simple measures can solve it:
Cut off at the source: Install silencers and flexible connections at the inlet and outlet to reduce airflow whistling and isolate vibration transmission.
Isolate the path: Use spring vibration isolators to support the fan, and wrap ductwork with damping soundproof materials.
Build an enclosure: Construct a double-layer composite acoustic enclosure (steel plate + sound-absorbing cotton) to effectively suppress low-frequency humming noise.
Focus on maintenance: Regular cleaning, dynamic balancing, and bearing replacement—sudden noise increase is often a sign of abnormal operating conditions.
