Sample Specification:
The silencer shall be a Maxim Model MT21 and shall be heavy wall, all welded construction, protected by a single coat of shop primer, and suitable for mounting in any position. The exhaust passage shall be straight through and no packing shall be used. The silencer shall be complete with the following accessories:

MT41 – Straight Through, Low Pressure
Drop Design – Expected Attenuation is 19
to 22 dBA

Use an MT41 for better than average silencing
in areas where ambient noise is relatively low
and back pressure requirements call for a low
pressure drop silencer.

MT31 – Straight Through, Low Pressure
Drop Design – Expected Attenuation is 16
to 19 dBA

Use an MT31 for average silencing in areas
where some background noise is always present
and effective but not complete silencing is
needed and requirements call for a low pressure
drop silencer.

MT21 – Straight Through, Low Pressure
Drop Design – Expected Attenuation is 13
to 16 dBA

Use an MT21 for silencing in areas where
background noise is relatively high and silencing
is needed and requirements call for a low
pressure drop silencer.
