SDP Positive Pressure Compressed-air Breathing Apparatus is a kind of isolated breathing protection apparatus. It provides breathing protection for users in the environment filled with poisonous air or lacking in oxygen. When it is used normally, the pressure inside the veil is always higher than the outside environment. It prevents the poisonous air from entering the veil, so as to protect the users. This product can be used in fire fighting, petroleum, chemical, metallurgy and electric power industry and so on. Standard: According with GA124-2004 Positive Pressure Compressed-air Breathing Apparatus standard.
