Definitions

  • the present invention relates to a blower filter device for a blower filter system, comprising at least one filter, a fan arranged in a fan housing, a motor for driving the fan wheel and a control unit for controlling the motor and for processing device-specific parameters of the blower filter device. Furthermore, the invention relates to a blower filter system, comprising a blower filter device, a head piece and a connecting hose, which connects the blower filter device and the head piece in fluid communication with each other.
  • Blower filter systems are used for light and medium respiratory protection and support the user of respirator filters by reducing the breathing resistance in contrast to conventional gas masks and thus make a long fatigue-free application possible.
  • a blower filter system consists of the following main components: A blower filter device usually worn on the belt and a head piece, which is designed as a hood or mask. These two components are usually connected to each other via a hose. The contaminated air is sucked by means of the blower filter device through a filter, whereby it is freed from harmful substances and then passed through a hose to the head and fed to the respirator.
  • the blower filter device itself includes, among other things, a fan-driven fan and a volute casing. The energy for the blower unit is mostly provided by an accumulator.
  • a central control unit which controls the motor of the blower unit and can process inputs of the user.
