double-tank high-efficiency 304 dust mask spot supply large discount labor protection supplies source factory

 Suitable for workplaces such as mines, ships, and factories, providing effective protection for workers' health.

【Product Maintenance】：

1. The main mask should be cleaned with warm water and dried, and should not be exposed to sunlight;

2. Masks and gas masks should be stored in a clean, dry place with an appropriate temperature of -20°C to +45°C; the shelf life is 3 years.

3. After using the mask, clean it with warm water below 30°C or wipe it with alcohol until dry. Store it in a well-ventilated, dry environment with a temperature between 0–35°C. Do not bake or expose it to direct sunlight. Do not store it together with acids, bases, or other toxic substances.

【Maintenance】：

1. Replace with a new gas filter cartridge. It is available at this store. Simply unscrew the filter cartridge to prevent gas leakage, then tighten the cover after installation. Gently shake the filter cartridge by hand until no friction sound can be heard inside it.

2. Masks and gas filters should be stored in a clean, dry place with appropriate temperature. 3. There is no specific replacement schedule for the filter box; if you feel the air is unclean based on the working environment, remove it from the work area immediately and replace the filter box.

The data for the outer box is as follows:

QTY: 50 PCS/CTN

MEAS.: 50*33*57 CM

N.W./G.W.: 10/12 KG

The primary barrier against particles for dust masks is particulate matter. The concept of "dust" is relatively narrow; dust falls under the broader category of particulate matter, including dust (produced by mechanical breakdown), fog (liquid), smoke (produced by combustion, etc.), and microorganisms, also known as aerosols. Particles that can reach deep into the lungs require very small sizes, typically below 7 μm, and are called respiratory dust, which poses significant health risks and are the main cause of various pneumoconiosis diseases. Therefore, dust masks create a sealed space around the mouth, nose, and chin by covering these areas, forcing polluted air through filtration when the user inhales. The mask itself is usually made of particulate-filtering materials, secured with headbands or ear straps. Sealing at the face and nose is often achieved using metal nose clips, but other methods may also be used, and some models include a sealing pad at the inner nose clip area.

Scope of application: Applicable to dust exposure environments with an oxygen content of 18% or higher in the air; not applicable to environments with toxic gases.

Key features: The mask body is enlarged appropriately, and the vertical surface is changed to a curved surface to enhance density and reduce facial pressure.

Utilizing a layered three-dimensional dustproof powder, it expands the filtration area by 70% to reduce breathing resistance and improve dust prevention efficiency.

Replacing the dusting powder is simple and convenient.

This mask is a self-suction filtered semi-mask for protecting the respiratory organs, and its performance meets the GB/T2266-92 standard.

Main structure: composed of four parts—plastic body, filter box, breathing valve, and straps. The product features high dust resistance, low breathing resistance, comfortable wear, and easy cleaning. It is suitable for various environments with high-concentration coal dust, silicon dust, and other non-toxic dusts. Long-term use can effectively prevent the risks of pneumoconiosis.
