TF214D anti-poison respirator

TF214D anti-poison respirator

      The mask body is molded by injecting an odorless, light-weight thermoplastic elastomer with good elasticity, which is anti-aging, durable and easy to clean; the mask body contacts your face closely, with good stability and wide field of view; the product is designed with single filter cartridge, and has long service life, high filter efficiency and low respiratory resistance; bayonet assembly structure facilitates installation and disassembly of the filter cartridge and filter cotton, and the product has good sealing performance and can prevent inhalation of various toxic and harmful gases; the high efficiency electrostatic filter cotton ensures low respiratory resistance and can effectively prevent inhalation of low toxic particles, with high filter efficiency.

Technical requirements

      Protective time: The protective time of TF 214D non-powered air-purifying half mask depends on the performance of the selected filter.

Expiratory resistance ≤300Pa（160L/min）

Inhalation resistance ≤ 50 Pa (30 L/min)

                                  ≤130Pa（85L/min）

Binocular field of vision ≥ 65%, lower field of vision ≥ 35°

Mask leakage rate: When the IL of each action is used as the evaluation basis (i.e., 10 people × 5 actions), at least 46 out of 50 actions have an IL < 5%, and when the overall IL of the person is used as the evaluation basis, at least 8 out of 10 subjects have an overall IL < 2%.

Leak tightness of exhalation valve: the time for the exhalation valve of half mask to recover to normal pressure should not be less than 20 s, when tested with 1180 Pa negative pressure
