A silent-type supply fan is a type of mechanical device designed primarily to deliver or circulate air (typically in indoor environments) while emphasizing low noise emission as a key feature.

Key Characteristics:

Core Function: Works by drawing in air from one location and pushing it to another, facilitating air supply in spaces such as offices, hospitals, laboratories, or residential areas.
Silent Design: Incorporates noise-reduction technologies—such as sound-dampening materials, optimized fan blade structures, or low-vibration motors—to minimize operational noise. This makes it suitable for noise-sensitive environments where quietness is prioritized (e.g., bedrooms, libraries, medical facilities).
Application Focus: Balances air supply efficiency with acoustic performance, distinguishing it from standard supply fans that may prioritize airflow volume over noise levels.
