Explosion protection. fans Rosenberg Explosion-proof, etc.

Explosion-proof Rosenberg fans for explosive areas are manufactured and tested according to the level of technical knowledge. Possible contact surfaces between rotating and stationary parts, which can usually be sources of operational failures, consist of materials whose risk of ignition due to friction, grinding or impact is limited. If necessary, the suction and discharge openings should be protected from falling or suction of foreign objects by means of a protective grid, which must meet at least the requirements of EN 294. The characteristics of an optimally cooled electric motor are marked on the engine nameplate and indicated in the type test certificate. The nominal characteristics of the fan are indicated on its nameplate. In order to achieve a more optimal distribution of rotational speed stages over the entire voltage control range of motors with an external rotor, motors whose rated voltage is higher than the rated voltage of the fan can be used. In this case, the data on voltage, power, current, rotation speed and tA time also change.
