ACOUSTIC BLANKETS
ADDRESSING RADIANT NOISE ON FAN & BLOWER HOUSINGS
Shannon GES has developed noise reduction solutions to address radiant sound energy on fan and blower housings. Design considerations for temperature and environmental conditions, as well as noise reduction targets (4-15 dBa). Shannon GES Acoustic Blankets Solutions are ASTM tested, field validated and OEM endorsed. A self-contained insulation system, designed to fit complex surface geometry, integral fasteners make installation quick and easy.
