42 SPARK Ex Explosion-proof roof fans Application SPARK/Ex explosionproof roof fans are constructed especially for application in spaces where explosive atmosphere, as a mixture of fl ammable substances in a form of gas, vapour and mist (with the air), can occur. They meet the requirements of ATEX 95(94/9/WE) Directive. Structure Bent steel profi les make up a frame structure of the fan. The motor along with a directly mounted radial brass impeller is of Ex execution. As protection against the atmospheric factors is a steel sheet hood with additives ensuring the discharge of the electrostatic loads. Fan housing is equipped with a clamp with cooper cable to lead the electrostatic charges away. The lower part of the fan is equipped with a steel fl ange as a mounting element to the roof base. Impeller of the whole SPARK/Ex series have been designed within the aspect of low noise. After testing of several impellers in the KLIMAWENT Research Development Laboratory optimal examples of the lowest noise level were fi nally selected. In order to reduce further the noise entering the room, it is recommended to install the fan on a sound absorbing roof base TPD or TPDC. As standard, the steel parts, i.e. supporting structure, openwork outlet and the mounting fl ange and the hood are powder painted in bright-grey colouring (RAL 7035). Caution 1. Maximum work temperature of the motor +40°C 2. Fans can be applied for conveying the dry air of maximum dustiness 0,3 g.m³ 3. Fans cannot be used for conveying the air containing viscous impurities, that would deposit on the structure elements, (especially on the impeller), neither including aggressive compounds, which could have destructive eff ect on the construction.
