● Project Name: Industrial Supply Fan Unit Noise Control Project
● Location: Xuzhou, Jiangsu Province, China
● Industry: Healthcare & Medical Architecture
● Products Applied: Cleanroom-Grade Modular Soundproof Enclosures, Dust-Free Silencers, Isolation Mounts
Heavy supply fans at Xuzhou Mining Hospital operated continuously, radiating high-intensity airflow noise that affected hospital office quarters and inpatient recovery zones.
Because the system served a medical environment, the noise control materials had to be strictly dust-free, non-shedding, and compliant with hygiene standards, all while preserving ventilation flow rates.
● Cleanroom-Grade Modular Acoustic Enclosures: Engineered acoustic enclosures using non-dusting mineral cores wrapped in protective anti-shedding membranes and stainless/galvanized steel shells.
● Low-Resistance Duct Silencers: Installed low-static-pressure-drop silencers and acoustic louvers to suppress airflow noise without reducing fan static pressure or airflow volume.
● Vibration Isolation & Sealing: Installed spring-and-rubber composite vibration isolators beneath fan frames and applied medical-grade acoustic sealants across all assembly joints.
● Sound pressure levels in nearby sensitive hospital zones were reduced to meet strict healthcare acoustic standards.
● The cleanroom-compliant material design eliminated dust particle risk, keeping the hospital environment clean while maintaining full ventilation capacity.
