Product Description

Product DescriptionGas maskThe gas mask adopts a double-canister and single-eye window lens structure. The filter canister is an arc-shaped one, featuring good dynamic air tightness, low breathing resistance and balanced weight distribution. The lenses are made of flexible materials. They can be folded for convenient combat carrying and offer a wide field of vision. This gas mask can effectively protect against traditional chemical and biological warfare agents, industrial toxic and hazardous chemicals , and toxic chemical aerosols and particles . The mask's sealing frame has a folded edge, which is comfortable to wear and has good air tightness, and can meet the wearing requirements of more than 95% of adults. The mesh headband can be adjusted freely and is either too tight or too loose.

ApplicationStandardNoteSuch product conforms to relevant regulations of GB 2890-2009 Respiratory Protection - Non-powered Air-purifying Gas and Vapor Respirators. 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.

Mechanism of Action & Core FunctionsProduct AdvantagesThis mask features a large viewing window design. The lens adopts flexible material, delivering a broad field of view, and is foldable and easy to carry.

A dedicated spectacle frame is compatible with the mask. Users can fit customized prescription lenses matching their diopters into the frame, then assemble it with the mask, enabling myopic personnel to wear the gas mask conveniently.

The mask is ergonomically contoured to fit the natural curvature of the human face, delivering excellent wearing comfort.

The curved filter canister achieves a perfect fit with the mask body.

Anti-fog performance: Within the temperature range of -25~35 ℃, the viewing window remains fog-free, or any slight fogging will not obstruct normal observation.

Safety performance: All component materials are non-toxic and innocuous. Skin-contact materials cause no skin irritation.

Environmental adaptability: After undergoing high and low temperature, sand and dust, as well as rain erosion tests, the filter canister remains intact with a filtration efficiency of no less than 99.97%.

Compatibility: It can be well matched with helmets, external goggles, non-hermetic protective suits and communication devices, showing great compatibility for emergency rescue scenarios.

Communication performance: It features low voice transmission loss and clear sound transmission. The supporting electro-acoustic speech unit can connect with the reserved electro-acoustic communication interface of the mask.

Equipped with an independent drinking water function for convenient water intake while wearing.

FAQQ1: What are the types of gas masks and how to choose them?Q2: What are the correct wearing steps?Half-face respirator: Covers only the nose and mouth; lightweight with good field of vision. Suitable for low-risk and long-duration work such as home renovation and pesticide spraying. It does not protect against eye irritation, so goggles need to be worn separately.

Full-face respirator: Covers the nose, mouth and eyes with strong airtightness and full protection. Ideal for chemical operations, fire scenes and highly toxic environments; slightly heavier in weight.Inspection: Check the mask for cracks, confirm the gas filter cartridge is intact and within validity period, and verify head straps are in normal condition.
Assembly: Screw the filter cartridge tightly into place; install the filter cotton following the air flow direction (usually the colored side faces outward).
Wearing: Hold the mask with both hands, put it on from bottom to top; adjust the neck straps first, then the top head straps. The tightness is proper when one finger can be inserted between the strap and face.
Air tightness test (mandatory):
Inhalation method: Block the inlet of the filter cartridge with hands, take a gentle breath. It is qualified if the mask slightly collapses with no air leakage sound.
Exhalation method: Cover the exhalation valve with hands, exhale gently. It is qualified if the mask slightly bulges with no air leakage.Q3: How to clean and maintain after use?Q4: How to store when not in use for a long time?Remove the filter cartridge and filter cotton (disposable, discard after use).
Clean the mask with neutral detergent and warm water, wipe clean with a soft cloth, and air dry naturally. Do not expose to direct sunlight, bake or use high temperature.
Focus on cleaning the exhalation valve and sealing ring, and check for deformation or adhesion.Mask: Hang or lay flat, avoid folding and squeezing; place the silicone side upward to prevent deformation.
Filter cartridge: Store in a sealed original bag or sealed box separately, keep away from chemicals, high temperature and humidity.
Storage environment: Keep dry and ventilated with temperature ≤ 30℃; do not store together with oil, acid and alkali substances.
Regular check: Inspect the mask elasticity, head strap durability and filter cartridge validity period once a month.
