The VANEC Model 144 Exhaust
Quieter is designed for use in suppressing the exhaust noise of any internal combustion
engine. This model is designed particularly for engines that produce higher levels
of low frequency tones.
The Model 144 Exhaust Quieter, when properly applied, will reduce engine exhaust noise
to a community acceptable level for dwellings located further than 200 ft. from the
exhaust tail pipe.
Pressure drop on the VANEC Model 144 will normally be between
2.50 in. W.G. and 10 in. W.G. for exhaust velocities between 3,730 fpm and 7,430 fpm at an
exhaust temperature of 750° F. These figures include exit loss
to atmosphere.
The VANEC Model 144 Exhaust Quieter may be mounted either
vertically or horizontally.
For situations that require more attenuation, including low shell noise, see the VANEC Model 154.
