Fan soundproof room with a multilayer of Patent eliminate noise, noise noise ≥ 45dB (A). 
 Fan noise is mainly composed of three parts, into the air damper tube vibration noise, the fan motor noise, high-speed exhaust noise. 
 Governance of the fan noise soundproof room to consider three factors, fan exhaust problem, fan motor cooling problems, maintenance channel problem. 
 Our own design and development of fan noise room, from the three aspects of starting with the efficient elimination soundproof walls, efficient sound insulation access door activities silencer inserts and outlet muffler rain grille. From multiple perspectives to solve the challenges facing the fan noise.
