blower muffler
1, use range is very wide
2, will not more than 85 to 90 decibels
3,applicable to all kinds of centrifugal
Blower muffler
blower muffler is mainly used to exhaust blower fan noise of the ROM watts series, axia
l flow fan series , can also in vent pipe and other high pressure fan's noise reduction, the sound
deadening capacity is 15-30 dB(A), the pressure loss less than 500 Pa.
Therefore this product uses the resistance type structure to eliminate the high, medium frequency
noise, and resistance to type structure to the medium, low frequency noise, at the same time uses
high frequency and low frequency two silencing area in resistance type channels,for broadening atten
uation band furthest, in order to achieve favourable silencing effect.
YF series ventilation pipe fan muffler and drum induced draft fan muffler applicable to all kinds of
centrifugal and axial flow fan and Bates, arjen robben air compressors.
The fan used in industry, is part of the continuous operation equipment. Noise criteria of this
equipment ruled by international organization is less than 90 db. A new standard of our country is
same to it, and the continuous noise of industrial enterprise is also on the basis of it.but when not
using the silencing measures, the noise from the fan's inlet and outlet to the environment can reach
110 or 120 decibels.
This type, blower fan muffler series products is acoustic impedance flow pattern muffler.We know,
noise source in the biggest noise level, the spectrum is often not one kind, for different frequency
spectrum, the require of magnitude is not the same.
Therefore this product uses the resistance type structure to eliminate the high, medium frequency noise,
and resistance to type structure to the medium, low frequency noise, at the same time uses high frequency and
low frequency two silencing area in resistance type channels, for broadening attenuation band furthest, in order
to achieve favourable silencing effect.
