Noise Curtains

Vacuum Pumps on Mezzanine Deck

A custom printing and bindery plant had a bank of vacuum pumps that were making excessive noise in the nearby office and break room. The plant engineer decided to use a BSC-25 curtain system that reduced the noise immediately outside by over 14 dBA (a 68% reduction). Management was pleased with the overall noise reduction and the appearance while the plant engineer was additionally satisfied with the ease of installation.

The curtain system met the local fire regulations and did not interfere with existing lighting and fire sprinkler systems. Installation was performed by the night maintenance crew and penetrations for piping was done with the "field installation kit."

This photo (seen on opposite side) shows how the noise curtains can be cut to fit around piping and steel work.
