Dissipated hot air stream is rerouted in and silenced, which flows by machine parts helping dissipating parts heat; muffled by exhaust guiding duct which it flows through to eliminate and confine the soundwave within the machine and totally deminish noise leak.
Flame durable fire-proof muffling material, reflection absorbing in airtight space reduces middle and high frequency
mechanical noise;insulates noise spread, UL117 fire-proof standard conforming.
Axial flow industial fans of low RPM, large angle and big flow, effectively supress high frequency noise.
Settings for low RPM and big flow air compressor reduces the generation of high frequency noise..
