Dust masks (Particle filtering half masks) to enter the lungs of the air has a certain filtering effect, in the respiratory infectious diseases epidemic, in dust and other contaminated environments when the operation, wear masks have a very good
Masks, generally can be broadly divided into air filtering masks and air supply masks.
Air-filtering masks, referred to as filtering masks, work on the principle of making the air containing harmful substances through the mask's filter media filtering evolution before being inhaled.
Air-supply mask, refers to the clean air source isolated from harmful substances, through the role of power such as pressure air machine, compressed air cylinder device, etc., through the tube and mask to the human face for breathing.
Dust masks (Particle filtering half masks) are categorized into 3 grades according to the filtration efficiency and ^great total leakage rate: FFP1, FFP2, FFP3.
According to the European Union's EN149:2001+A1:2009 standard, the masks are categorized into: FFP1 (minimum filtration efficiency >. 80%), FFP2 (minimum filtration effect >94%) and FFP3 (minimum filtration effect >97%) three categories. Know
FFP1 (corresponds to GB2626-2006 KN90, KP90), FFP2 (corresponds to GB2626-2006 KN95, KP95), FFP3 (corresponds to GB2626-2006 KN100, KP100).
The standard to be conformed to for CE marking of dust masks is EN 149.
The material composition of dust masks is generally non-woven fabrics, meltblown fabrics, activated charcoal, respiratory valves, etc. The material composition of dust masks is usually non-woven fabrics, meltblown fabrics, activated charcoal and respiratory valves.
Dust masks belong to the European Union PPE certification directive in the category III products. In addition to passing the required tests, factory audits are also performed. Similar products include escape masks, multiple respirators, and gas masks.
Products exported to the EU, need to be marked with the CE mark, the product classification level, the code of the certification body, the date of certification.
