What is fresh air?
fresh air respirator uses a pump and a long air hose to provide the wearer a constant respiratory air supply in situations where other types of respirators would fail. This allows the wearer to work in conditions where particle respirators and chemical cartridges would fail and cause physical damage or carrier death. Each component of the fresh air respirator plays an important role in the provision of fresh air to the user. In order to ensure the safety of the wearer, each fresh air respirator must be checked before use and the work area needs to be checked to ensure that the components of the system are not damaged while the wearer performs his work. Two filters are attached to the sides of the pump body to provide safety failure if one of the filters is caught with dust or other free residues. To ensure the correct amount of air requires the air pump filters before and during use and replacement when it is damaged oro Too dirty. The cleaned filters must dry thoroughly in order to prevent moisture from entering the pump's inner fan and cause the fan to bind. There is another part for the air pump socket that requires thorough control to ensure the carrier's safety.
connected to the air pump is a long air hose that transmits pressure air to the input of a respirator full of face, which wears a person working in the hostile respiratory environment. The air hose inspection before and between use ensures that the air does not flow into the atmosphere before reaching the wearer. Most air hoses are made of heavy wires surrounded by heavy flexible rubber coating. Piercing heavy rubber is difficult, but possible when sharp or heavy objects hit the hose. One last component requires an inspection and is the most important part of the fresh air respirator.
KTERiens wear a person who performs work in an enemy environment, the hood of the fresh air respirator holds fresh air around the wearer's face. Unlike the heavy construction of the air hose, the hood is made of lightweight material to ensure comfort of the wearer. The bonnet inspection before each use ensures that the wearer has sufficient fresh air supply and can clearly see through the protective lens.
