Respiratory protection - screw-type filters for full face mask BRK 820
The filters are tested and approved to EN143 / EN 14387 and carry the CE mark. Offer very low breathing resistance. Their lifespan depends on the toxicity, humidity and air consumption of the user. Measurements differ with application so it is impossible to predict the working lifespan. Filter exhaustion can be detected as follows:
- Gas filters: appearance of odours, tastes or irritants in inhaled air.
- Particle filters: increase in breathing resistance.
Storage times for unused gas and combination filters (kept sealed in manufacturer's packaging) 6 years. Opened gas filters must be replaced after maximum 6 months, even if unused. Particle filters can be stored for an unlimited period.
