Product Features:

A fan is a versatile mechanical device with a wide range of applications. The noise generated during its operation often becomes a source of harm to workers' health and environmental disturbance. The noise standard set by the International Organization for Standardization (ISO) for such equipment is ≤90 decibels. However, without noise reduction measures, the noise emitted from the fan's inlet and outlet can reach 110–120 decibels, significantly exceeding the compliance requirements. After proper installation of this product, its maximum noise level will not exceed 85–90 decibels.
