In dust-proof operations, Fangdun's dust-proof half mask has become the choice of many frontline workers due to its scientific structural design, compliant filtration performance, and comfortable wearing experience. According to different working environments and conditions, it mainly includes the following core products:
1、 Classic single filter cotton half face mask (7200B)
This type of product focuses on lightweight and high cost-effectiveness, suitable for low to medium concentration dust operation scenarios. Its core advantage lies in the large air intake and aerodynamic optimized valve seat design, which effectively reduces suction resistance and makes long-term operations less suffocating. The mask body is made of soft liquid silicone material, combined with wide elastic bands, which can evenly distribute head pressure. In addition, it adopts a three-point buckle and a 45 ° rotating knob design, which allows workers to quickly disassemble and assemble the filter cotton even if their hands are stained with dust, making daily maintenance very convenient.
2、 1105 series double filter cotton protective half face mask
The 1105 series is designed specifically for heavy dust and high-frequency vibration environments, featuring a dual filter element design for greater dust holding capacity. This series is equipped with KN100 level filter elements, with a filtration efficiency of up to 99.97% for non oily particles above 0.3 microns, which can effectively intercept fine particles such as metal shavings and rock dust. The mask body is made of soft liquid silicone material, which has a skin friendly touch and is resistant to high and low temperatures. In terms of detailed design, the 1105 series adopts a multi-point tension headband system, which is stable and leak proof during intense operations such as polishing; At the same time, it significantly reduces the stuffiness of wearing and is very suitable for high-intensity work.
3、 Dust and toxin dual protection combination face mask
This half face mask demonstrates strong compatibility for complex environments with both dust and odors, such as spray painting and welding. Its base can quickly replace filter cartridges for organic vapors and acidic gases, or install KP filter cotton for oil resistant particles. Combined with a semi open contour and cold flow exhalation valve, it achieves dual protection against dust and toxins while ensuring a wide field of view and smooth breathing.
Whether dealing with heavy dust or complex exhaust gases, Fangdun dust half masks provide segmented solutions. It should be noted that all filter type half masks are not suitable for hypoxic or unknown toxic environments. Proper selection and standardized wearing are the key to ensuring respiratory safety.
