Hospital / Clean Room Attenuators
     
 
Application

Hospital/Clean Room attenuators are available in three models, specifically engineered for sensitive area applications requiring broad band noise reduction coupled with erosion proof acoustic fill. Performance data is provided for four basic lengths - 36”, 60”, 84”, and 120”. Units are also offered in 48”, 72”, and 96” lengths..

Model SPC: Hospital grade unit providing excellent attenuation for system velocities in the range of
500-1000 FPM.

Model MSPC: Provides high attenuation values along with a moderate pressure drop in systems operating at 750-1250 FPM.

Model MPC: Provides good attenuation values along with a moderate pressure drop for systems operating at 1000-1500 FPM.

Model MLPC: Provides a low pressure drop for systems operating at 1250-1750 FPM.

Model LPC: Provides an excellent pressure drop for systems operating at 1500-2000 FPM.

Special features of our Standard Attenuators are:

  • Diffusion angle to improve pressure drop
  • Bellmouth entrance to help minimize
    turbulence
  • 22 gauge galvanized steel casings
  • 24 gauge perforated galvanized baffles
  • Acoustic fill encapsulated in polyethylene to
    eliminate erosion and absorption of gases
  • Acoustic stand-off between the perforated
    baffle and the acoustic fill to enhance
    performance
  • Seams are mastic filled to insure airtight units
    to 8” w.g.

ASTM E-84 ratings for the acoustical fill are:

  • Flamespread 0
  • Smoke Developed 15

Components are also available in stainless steel or aluminum construction.

Acoustical performance ratings are based on tests conducted by Intertek Testing Services, formerly ETL Testing Laboratories, Inc., Cortland, New York, in accordance with ASTM E477 “Standard Method of Testing Duct Liner Materials and Prefabricated Silencers for Acoustical and Airflow Performance.” Copies of the test reports are available upon request.
