Respiratory Protective Dust Mask is mainly composed of mask body (half mask), filter element (dust filter cartridge), exhaust valve and strap. The mask is made of silica gel materials and is soft in quality, comfortable to wear for a long time, simple and durable. The product contour design fully considers the matching with Asian facial bones. The filter element is made of filter cotton and melt blown cloth, which has high filter efficiency, large dust holding capacity and low respiratory resistance.
It is widely used in welding, mining, casting, metal smelting, polishing and chemical industries, and other workplaces that produce dust.
Structure:
- Half Mask
- High Filter Efficiency
- Large Dust Holding Capacity
- Low Respiratory Resistance
- Elastic Band
- Air Purifying Particle Respirator
- Soft Silicone Rubber Material
| Technical Requirements | |
| Appearance | The surface should be free from damage, deformation and other obvious defects |
| Filter efficiency | ≥ 95.0% |
| Leakage rate | when the leakage rate of each action is taken as the evaluation basis (i.e, 10 people × 5 actions), the leakage rate of at least 46 out of 50 actions should be < 11%, and when the overall leakage rate of people is taken as the evaluation basis, the overall leakage rate of at least 8 out of 10 subjects should be < 8%. |
| Expiratory resistance | ≤ 150 Pa |
| Inhalation resistance | ≤ 300 Pa |
| Leak tightness of exhalation valve | The leakage flow of expiratory valve should not exceed 30 mL/min, when tested with 249 Pa negative pressure. |

The predecessor of West Line Protection is a manufacturer with over ten years' experience in synthesizing high-performance polyethylene for industrial and military application in Hebei province. Thanks to the intimate relationship with local colleges and institution. West Line Protection mastered the technologies for ballistic PE fabrics and received orders from partner enterprises and customers. With the improvement of our technology and enrichment of partner members, we were invited in a collaboration to develop aramid fabrics and, later, co-founded aramid factory with peer enterprises to satisfy our customers domestic and overseas.
Now we have gained the mastery of both necessary ballistic fabrics, providing our customers protection in both prevalent ballistic products and customized ballistic products (more lead time), anti-riot products, and even basic materials in ultra high molecular weight polyethylene or aramid fabric. Still we are cultivating for more technology in protection industry.
