It is suitable for working places such as mines, ships and factories to effectively protect the health of workers.

[Product maintenance]]:

1. The main body mask is washed and dried with warm water, and it is not suitable to be exposed to the sun;

2. Masks and canister should be stored in clean and dry places with suitable temperature, suitable temperature-20 ℃ ~ +45 ℃, and the storage period is 3 years.

3. When the mask is used, wash it with warm water below 30℃ or wipe it clean with alcohol. Place it in a ventilated, dry environment with a temperature of 0 ~ 35℃, and do not bake it with fire, exposed to the sun. Do not put together with acid and alkali and other toxic substances.

[Maintenance]]:

1. Replace with a new canister. This shop is available for sale. Just screw it off at canister to prevent gas from bias current. After installation, tighten the lid of the box and gently shake canister by hand, so that the friction sound in the box cannot be heard.

2. Masks and poison filters should be stored in clean and dry places with appropriate temperature. 3. There is no specific replacement time for filter box. You need to feel that the air is not fresh according to the specific working environment and move away from the working area to replace filter box immediately.

The carton data is as follows:

QTY: 50 PCS/CTN

the main anti-blocking object of the dust mask is particulate matter. The concept of "dust" is relatively narrow. Dust belongs to the large concept of particulate matter, including dust (produced by mechanical crushing), fog (liquid), smoke (produced by combustion, etc.) and microorganisms, also known as aerosol. The particles that can enter the deep part of human lung are very small, and the particle size is usually below 7cm. It is called respiratory dust, which is harmful to health and is the main cause of all kinds of dust lung diseases. Therefore, the dust mask forms a space sealed with the face by covering the mouth, nose and chin of the person, and forces the polluted air to be filtered by inhalation. The mask body is usually made of particulate matter proof filter material, which is fixed by headband or ear band. The seal of the face nose is usually shaped by metal nasal splint, but it is also realized by other methods, some also increase nasal splint in a seal parts of the mask.

Scope of Application: it is applicable to dust-exposed working environment with oxygen content above 18% in the air, and not applicable to toxic gas working environment.

Main features: the main body of the mask is enlarged appropriately, and the facade is changed to a curved surface to improve compactness and reduce the pressure on the face.

With laminated three-dimensional dustproof powder, expand the filter surface 70% to reduce respiratory resistance and improve dust blocking efficiency

replace dustproof powder, simple and convenient

this mask is a self-priming filter half mask respiratory organ protection mask, and its performance meets GB/T2626-92 standard.

Main structure: plastic body filter box breather valve and lace-up four parts, the product has the characteristics of high dust blocking efficiency, low breathing resistance, comfortable wearing and convenient cleaning, etc, it is suitable for all kinds of high concentration coal dust silicon dust and other non-toxic dust working places. Long-term use can effectively prevent the hazards of occupational diseases of the lungs.
