فیلتر ماسک بی ال اس مدل BLS 311 A2
فیلتر فوق برای ماسکهای تمامصورت و نیمصورت مورد استفاده قرار میگیرد. شرکت «بی ال اس» (BLS) این فیلتر را عرضه میکند و بهتر است از آن برای ماسکهای تولیدی این شرکت استفاده شود. این فیلتر با نام مدل «311A2» شناخته میشود و با توجه به کد رنگ قهوهای رنگ آن میتوان دریافت که این فیلتر برای محافظت از ریه دربرابر گازها و بخارات طبیعی با نقطهی جوش بیش از 65 درجهی سانتیگراد مورد استفاده قرار میگیرد که در این بین میتوان به گازهای حلال اشاره کرد. این محصول دارای استانداردهای EN 14387: 2004 و A1: 2008 است. برای استفاده از فیلتر فوق بهتر است دمای محیط کمتر از منفی 10 و بیش از مثبت 50 درجهی سانتیگراد نباشد. این محصول در رطوبت بالاتر از 80 درصد کارایی خود را از دست میدهد و این نکته نیز باید مورد توجه قرار گیرد. استفاده از این فیلتر برای گازهای بیبو و بدون طعم ممنوع است.
- مناسب برای جلوگیری از استنشاق گازها و بخارات طبیعی با نقطهی جوش بالای 65 درجهی سانتیگراد مانند حلالها
- قابل استفاده در دمای منفی 10 تا مثبت 50 درجه سانتیگراد
- قابل استفاده در رطوبت بالای 80 درصد

Application, Limitation, Warning
BLS filters cannot be used in the following conditions: - when the type and concentration of contaminant is unknown. -when the oxygen content is lower than 17% in volume (which is often the case in closed environments such as wells, tunnels, cisterns, etc). -when the contaminant is carbon monoxide or an odourless and tasteless gas. -when certain conditions are dangerous to the worker health and life. -The filter must not be modified or altered. - Leave the work area if the respirator becomes damaged, resulting in difficulty breathing and/or faintness. - Persons whose olfactory sense is altered shall not use filter respirators. -The use of gas or combined respiratory protective devices during works with open flames or liquid metal droplets may cause serious risk to the operator. -AX filter shall be used only once and at the end of such period it shall be disposed of.
Filter use and maintenance BLS filters must be used in pair connected to BLS half masks model TP2000 R and TP2000 S and to full face masks model BLS 5250 and BLS 5500. Carefully read the instructions for use of the filters and the one of the equipment (half mask or full face mask) is used with. Two new filters are packed in a sealed plastic bag. Choose the filter keeping attention to the colour and identification marking and check that the filter is of the correct type for the intended use. Check that the filter is not empire (the expiry date is printed on all the filters; this date shall be valid if the filter has been kept sealed at the recommended storage). Inspect both the filter and facepiece for any breaks or damage. For use, open the sealed packet, fit the two filters to the filter housing on the half mask or full face mask, screwing the filter tightly. Mind You: the P2 filters are used by being attached to gas filters positioning them over the gas filters and fixing in place by a plastic press-fit cover (the combined filters obtained with this coupling must be used always twin). In normal use conditions, the shelf life of the filter is not only due to the pollutant concentration but to many other elements difficult to be determined, such as the degree of air humidity, the air temperature, the inspired air volume, the weariness of the worker, etc. The worker shall leave immediately the work area and replace the filters when start to smell the contaminant. At the end of the work shift, the respirator shall be stored in a clean and dry place, according to the storage conditions indicated in the user information. The BLS filters does not require maintenance and does not need to be cleaned, regenerated or blown. Exhausted filters shall be replaced at the same time and dismantled according to the National regulations and considering the substances they have retained
Storage time: 5 years (factory sealed), as shown on label - pictogram of hourglass
Storage conditions: temperature range -10°C e +50°C, Relative Humidity < 80%
