Transfer unit RW60, REC Indovent

Art. no.: 6521020

RW60 is a noise reducing excess air device that ensures that the sound value of the wall is maintained. With RW60, you'll get a complete solution with silencers and under ceiling units that meet all sound requirements when high noise reduction is required. RW60 meets the over hearing requirements for transfer air in all buildings that are up to sound class A.

The air duct has been developed to provide very good noise reduction with low pressure drop as well as the greatest possible combination of mounting flexibility while providing high airflow (up to 50 l / s) through high free area and very good noise reduction.
Well suited for use in schools, offices, hospitals, laundry rooms or in other areas where there is a sound dampening requirement for the wall.
