The MUB-EX is the right solution for ventilation in potentially explosive areas. With this new range of fans, Systemair offers the most flexible ATEX-tested and insulated fans available on the market. The new MUB-EX combines maximum safety with optimal flexibility.
The fans have been tested according to ATEX directive 2014/34 / EU – II 2G Ex h IIB + H² T3 Gb – and equipped with backward curved steel radial impellers and voltage controllable external rotor motors. The inlet nozzle is made of copper, which prevents sparks even in exceptional cases.
The voltage-controllable external rotor motor has cables connected to a motor protection. The frame profile of the housing consists of corrosion-resistant aluminium with plastic corners, which ensures the highest possible impact resistance. Thanks to the 30 mm insulation, the housing protects perfectly against annoying ventilation noises to the environment. This layer of mineral wool and the fasteners used also provide thermal decoupling.
The air direction of the MUB-EX fans can be changed on site. As standard with these MUB series, these fans are designed for straight airflow. Due to the flexible components, the air direction can be adjusted at any time location.
