Method and the device for protecting against exhaled contaminants of the air

摘要

The purpose of the notification is to provide a means and device to protect against airborne pollution. The way to protect against inhaled air pollution is to:that the air breathed by the user is sucked under pressure from 2x105 to 10x105 Pa and the efficiency from 100 to 330 l /min from the nearest vicinity of the nose and mouth of the user by the intake air nozzle (4) in the face zone,they are then flown through the air flow channel (3) and the flexible line (2) to the air pressure module (1) and outside the protected zone,and the air pressure module (1a) is supplied with a flexible (2a) air flow rate with regulated pressure from 2x105 to 15x105 Pa and efficiency from 100 to 2000 l /min to air flow channel (3a),and then to the exhaust air (4a) in the face zone of the user,from which laminated air is flowing at speed from 0,5 to 2 m /s,favorably 1,5 m /s creates an air curtain separating the face area of the user from the outside air. The device consists of an air pressure module (1),which is connected by a flexible line (2) with an air flow channel (3),and then with intake air nozzles (4) equipped with regulated airhole (s) (7) and air pressure module (1a),which is connected by a flexible line (2a) with an air flow channel (3a),and then with an outlet air nozzle (4a) equipped with a regulated orifice or outlet air orifice (7a).
