摘要

"Hood respirator to be wearing on the head of a user to provide a supply of breathable air to a region of the user's face".The invention relates to a hood respirator (1) which has an air chamber (6) arranged above the head of a user for supply of breathable air.The air chamber (6) has an air inlet (13) connected with a hose of the air supply (5) and an air outlet (17). The output (17) is willing to direct air away from the eyes of the user.The air chamber (6) to form an air duct (12) which substantially covers the top of the hood (1) above the head of the user.The duct (12) is resistant to shrinkage, so that the shape of the duct is maintained in the use and air flow through the duct (12) is substantially unrestricted.As a result, a substantially uniform air flow can be achieved, in use, air flow pattern that can be repeated from one day to another and a hood for another.
