Kansas City, MO, November 18, 2003– Ruskin Sound Control announces the introduction of the industry’s first silencers to receive the coveted Certified Ratings Seal from Air Movement and Control Association International, Inc. (AMCA International).  The Ruskin Sound Control SPS and TPM silencers models, both available in 3 feet and 5 feet sizes, passed AMCA International’s rigorous review process, met its strict E-477 requirements, and received its specification validation. The SPS models provide superior low- and mid-band noise reduction, the TPM models offer excellent broad-band performance at reduced static pressure loss, and with AMCA International’s Certified Ratings Seal, manufacturing data can be compared with confidence.

Backed by almost 80 years of standards development, AMCA International is the world’s leading authority in the development of the science and art of engineering as it relates to air movement and air control devices.   AMCA International’s Certified Ratings Program, developed in response to the concerns over product performance, is the only international ratings program for air system components. To earn the distinction of displaying an AMCA International performance seal, a product line must be tested and rated in AMCA International’s laboratories and the manufacturers’ catalogued ratings submitted and approved. 

Since 1966, Ruskin Sound Control has been recognized as a leading manufacturer of acoustical duct silencers.  Its products are engineered to fit the needs of virtually any application, tested in a full acoustical laboratory to ensure performance, and built to last.  For more information on the Ruskin SPS and TPM models, other Ruskin Sound Control products, or analysis programs, contact your local Ruskin Sound Control representative or visit www.ruskinsound.com.
