For Bartels Rieger cartridge filters, we differentiate between three areas:

• Gas filters
  The gas filters protect against vapours of organic compounds with a boiling point higher than 65 °C (A),
  inorganic gases and vapours (B) sulphur dioxide (E) and ammonia (K).
• Particle filters
• Combined filters
  Combine the protection of a gas and particle filter in one product

Cartridge filters can only be used in combination with a filter adapter on face pieces with thread connector connection.

The coarse dust pre-filter for cartridge filter adapters protects the filter against being loaded by particles or aerosols too quickly.

For insert filters and DUETTA filters.
