Products Noise Reductors

Noise reductors are manufactured to reduce the noise in air conditioned and ventilated areas. The housing of the reductor is made of galvanized steel sheets. Chokers are made of a flame retardant, absorbing material – fiber glass. A significant reduction is achieved in the noise frequency range from 63 to 8000 Hz.

Rectangular noise reductors and Chokers

Noise reductors are manufactured to reduce the noise in air conditioned and ventilated areas. The housing of the reductor is made of galvanized steel sheets. Chokers are made of a flame retardant, absorbing material – fiber glass. A significant reduction is achieved in the noise frequency range from 63 to 8000 Hz.

The area of the chokers is protected from wear up to air speeds of roughly 20 m/s.
