LOW FREQUENCY ATTENUATORS

Standard attenuators are available in three models for traditional applications requiring broad band noise reduction. Performance data is provided for four basic lengths - 36”, 60”, 84”, and 120”. Units are also offered in 48”, 72”, and 96” lengths.

 

Model HP is a standard pressure drop unit ideally suited for system velocities at or near 1,000 fpm.

Model MP also provides excellent attenuation values along with a moderate pressure drop at somewhat higher air velocities.

 

Model LP offers the lowest pressure drop for higher velocity systems.
