The VANEC Model 154 Super
Critical 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 and situations where shell noise is a factor.
The Model 154 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 154 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 154 Exhaust Quieter may be mounted either
vertically or horizontally.
For situations where shell noise is not a factor, see the VANEC Model 144.
