SOUND PROOF DUCTING

CLTD Sound Proof Ducting is designed and optimized by CLET on the basis of original prototype. The Ducting consists of flat steel shell, metallic framework, composite acoustic material, metal punching plate and surrounding flange. The space between punching plate and external shell is filled with acoustic pillow. Thanks to advanced plating processing technique and design conception, the quantity of components being used has been greatly reduced and thus cutting the cost.
