  "textContent": "The system has an air guiding housing in which a fan (1) is arranged at upstream of a heat exchanger. The fan has a direct-current motor (3) that is provided with a brush (6) and a commutator, where cooling air flow (K) for cooling the motor is branched from main air flow flowing through the fan. The main air flow is free from particles of abrasion developed in the motor. The commutator and the brush are enclosed by a cover. A fan wheel (2) of the fan is connected with the motor over a motor axle (4) of the motor, where the brush is arranged at the motor axle.",
