A blower device for a respiratory protection system comprises a fan for a generation of an airflow and comprises one or more filter element that is flowed through by the airflow. The fan is arranged at least partly beside the one or more filter element. The airflow is deflected between the fan and the filter element.

Blower device for a respiratory protection system

A mouth protection device for a respiratory protection system, in particular a blower respiratory protection system, includes at least one mask base body which is configured to cover a mouth and/or nose region of a user and which delimits a breathing zone at least partially, and includes at least one breathing air supply line, which is connected to the mask base body and delimits at least one breathing air channel that ends in the breathing zone and is configured for guiding an active breathing air flow, wherein the mask base body is made at least largely of a flexurally soft material, the mask base body being made at least largely of a textile material.

Mouth protection device for a respiratory protection system

The invention is based on a sun protection device, in particular sunglasses, with at least one optical sun protection filter comprising at least one liquid-crystal cell, and with at least one sensor unit, which is configured for capturing a solar irradiation. It is proposed that at least one sensor cover, which covers a sensor surface of the at least one sensor unit at least partly and which is, at least partly, at least substantially opaque with respect to an irradiation of a visible light spectrum.
