Industrial sound insulation and noise reduction products: soundproof room, soundproof room, anechoic room, semi-anechoic room, anechoic room, soundproof box, soundproof cover, silent box, motor noise reduction, boiler noise reduction, generator set noise reduction, range hood It is widely used in laboratories and production lines to test various products such as industry and mixers. Other applications are used in conjunction with equipment such as air conditioning units, pump rooms, fans, and workshops.

Structure: The outer shell is made of 1.5mm cold-rolled steel plate, and the interior is made of 3-6 layers of damping, sound insulation and sound-absorbing materials.

  The steel plate is plated with anti-rust treatment, the surface paint adopts ICI computer toning, spraying protective metal paint.

Sound insulation range
