The fans of the BOX-T ATX series are particularly adapted for plant installation where it is necessary to exhaust air at a low noise level. Thanks to their specific construction, such fans are ideally installed in industrial plants complying with the ATEX Directive 99/92/CE and built-in compliance with the ATEX directives 94/9/CE and 2014/34/EU.

The low noise level is given by their plenum lined with thick acoustic material which allows a remarkable reduction of the noise inevitably generated by such type of fans. The blower
consists of a double inlet forward curved connected to the motor by belts and pulleys. The series BOX-T ATX is designed for installation in ATEX certifi ed plants category 3, zone 2, zone 2-22 (3G). They are suitable for coveying air with temperature from -20°C to +40°C.
