Air extractors EXT The range of products designed for air treatment inside the vessels includes air extractors. EXT air extractors allow the expulsion of the vicious air outside from the leaving ambient (typical application is the air extraction from the toilets). The prescribed air change number along the time and the ex- pulsion of the vicious air, assuring the finest quality of the air inside. Each unit is covered by an insulated box to reduce at the minimum possible the noise emission. Sizes and technical features (air flow, head pressure and cooling capacity) of air extractors are designed according to the specific needs of each vessel apart of those standard models described in the table below.
