world-ppe.com presents masks for respiratory protection that prevent inhalation of harmful particles. The catalog contains two types of PPE. The first includes models that cover the face completely, providing protection against air pollution up to 50 MAC. The second type is half-mask respirators that cover the lower part of the face. A modern mask for respiratory protection is a lightweight device that is not tiring when worn for a long time, allowing it to be combined with other personal protective equipment (goggles, helmets). Elastomer and other materials provide a tight fit and do not cause skin irritation.
