Explosion-proof wall fan 500/R/6-6/45/400/Ex - 9340 m3/h

Explosion-proof wall fan 630/R/5-5/45/400/L/Ex - 12200 m3/h

ATEX explosion-proof axial fans are designed for use in spaces where there is a probability of explosive atmospheres resulting from the existence of mixtures of air with gases, vapours, mists (equipment group II, category 2). The fans are driven directly by the shaft of the electric motor. Fans are in the category of 2G devices, which means that it is necessary to eliminate the ignition source or that the ignition source must be isolated from the explosive environment. Additional measures have been taken in the design of the fans to ensure increased safety against the possibility of excessive temperatures, arcs and sparks both inside the engine and on external components during normal operation. 

The fans meet theT3 and T4 temperature classes - i.e. the maximum temperature of any part of the fan in the most unfavorable but permissible conditions does not exceed 200 and 1350C, respectively. The temperature class of the fan depends on the type of explosive atmosphere pumped by the fan. The fans are designed to work in a horizontal position. They can also work in an upright position, with the shaft tip pointing down or up. In this case, the vent cover is equipped with a protective canopy. The fan should be used at ambient temperatures between –20°C and +40°C. Each fan has its own individual aerodynamic characteristics, which allow you to select the device for your specific application.
