TF-10D gas mask

TF-10D gas mask

      TF-10D gas mask is mainly composed of mask and filter. The mask body is treated by adopting rubber injection molding process, which has tight sealing, good leak tightness and frosted surface, and can be used with protective garment; the sealing frame has double reversely folded edges structure, which is comfortable to wear; the face shield of the mask is made of polycarbonate, which has good optical performance and impact resistance; the lens is water-blocking type, which can ensure a clear field of vision; the respiratory communication device ensures a clear voice and small loss of sound transmission; the five headbands can be adjusted according to the head circumference of the wearer.

       The mask can be used in direct conjunction with the class-2 or used with class-3 filters through breathing hose. The gas mask can be equipped with various types of filters according to the protection requirements.

      The product can effectively protect its users from such toxic and harmful gases as chemical pollution, biological aerosol and radioactive dust. Moreover, it protects the respiratory organs, eyes and facial skins of personnel exposed in toxic and harmful environment from any injury caused by toxic gases in the environment around.

Such product conforms to relevant regulations of GB 2890-2022 Respiratory Protection - Non-powered Air-purifying Gas and Vapor Respirators.

Technical requirements:

Protective time: The protective time of TF-10D air-purifying gas mask depends on the performance of the selected filter.

Expiratory resistance ≤ 100 Pa (30 L/min)

Inhalation resistance ≤ 40 Pa (30 L/min)

Total field of vision ≥70%; binocular field of vision ≥55%; lower field of vision ≥ 35°

Inward leakage of mask ≤0.05%

       Leak tightness of exhalation valve: The drop of negative pressure is not more than 500 Pa in 45 s when tested with 1180 Pa negative pressure.

Note: It is strictly forbidden to use this type of gas mask under the condition of hypoxia. It is recommended to use long tube breathing apparatus, self-contained breathing apparatus or compressal air breathing apparatus.
