The tools which we offer for respiratory protection is very effective to protect the human nose, mouth and internal respiratory parts from chemical dust, effect of fire and other harmful objects. made of soft, colorless and non-allergic pure quality neoprene or other polycarbonate materials these masks offer maximum protection and comfort to the wearer.
MSA Compressed Airline System breathing apparatus function independent from the ambient atmosphere. They can be used in all places where the ambient air is not breathable because of contaminants or oxygen deficiency and where filtering devices do not provide sufficient protection. With the lightweight design and the unlimited time of compressed air supply from a compressed air line system, resp. a compressor, or a limited time of compressed air supply from a cascade cylinder, they are used for a multitude of applications in industry and mining. The following are some examples:
Long duration work that is restricted to a location, e.g. on construction sites, handicraft work, agriculture and for repair and maintenance work of tanks and containers in industry
In underground and surface mining
In all situations where a compressed air breathing apparatus would encumber the user because of the tight work space or where small entry ports do not permit carrying an apparatus on the back
For paint spray in handicraft work and industry
For sandblast work in shipping, high rise and underground construction industry
Design and Functioning:
The MSA compressed airline breathing apparatus consists of a facepiece that is connected to a compressed air supply by a compressed airline.
The facepiece can be a hood or a full face mask with a lung governed demand valve. The lung governed demand valves supply only so much air as is required during inhalation. Thus, the air consumption is economical which makes it especially suitable for cascade cylinders.
The connection between the lung governed demand valve and the air source is a connector or change-over valve [emergency air supply] that is fixed to the waist belt.
This prevents tensile force being transmitted to the facepiece. With hoods the air flow is regulated with a pressure control. This permits individual adjustment of the constant air flow from the air source to the hood as required. By fixing the control to the waist belt,this prevents tensile force being transmitted to the facepiece.
