Disclosed herein is an information display and control device of a powered air purifying respirator wherein air flow of a blower device is electronically detected using a precision air flow sensor mounted to the blower device without using an air flow display device, and a graphic screen that displays an air flow level meter is displayed on the blower device or an additionally manufactured remote controller so that the air flow of the blower device can be checked during operation, thereby easily and correctly recognizing system information and taking proper measures. Also, the information display and control device of the powered air purifying respirator includes a remote controller that is capable of allowing a worker to inspect an air flow state, to detect remaining battery power and expected use time, and to manipulate a blower device and exchanging information even in a state in which the worker wears the air purifying respirator and the blower device, wherein it is possible to control a designated electronic welding surface through infrared or wireless communication, and the remote controller is mounted to a belt or a designated position to prevent separation and loss of the remote controller and in consideration of operations based on switch errors.
