RESPIRATOR

摘要

The respirator consists of the filtering semi-mask with the horizontal folds, the obturator, the clamp for the nose, and the cord of the hood. The horizontal folds of the semi-mask are designed as upper and lower rows of corrugated elements interconnected with the aid of the rectangular bridge. The bridge is attached to the end-faces of the corrugated folds by the demountable fastening elements. The respirator also contains the distance piece representing two equal plates made of the elastic material.
