The box is made out of electroplated steel plate, powder- coated. Including protection guard. The installation is possible in each fitting position. The fan has an axial impeller with airfoils made out of electroplated, powder- coated steel plate. The actuation is carried out by an explosion- proofed, speed- controllable external rotor motor with completed barretter. A D/Y- capability of connection allows an double- rotation operation of the motor. For annealing the motor is situated inside the air flow. Impeller according to VDI 2060, quality class Q 6,3 and dynamically weigh heavy in two levels. Tested according to ATEX- Guideline 94-9-EG,conform to ATEX Directive 2014/34/EU.
