CA-28 EUROMASKI INSTRUCTIONS FOR USE
Introduction
CA-28 Euromaski welder's hood is designed for use with CleanAIR® Powered Air Purifying Respirators
(PAPR) or with Continuous Flow Compressed Air Line Breathing Apparatuses (CleanAIR® compressed air
systems) to protect respiratory tract, face and eyes against harmful ultraviolet/infrared radiation and welding
spray. For all approved product combinations see table C.
®
CleanAIR is a personal respiratory protection system based on the principle of the fi ltered air overpressure
in the breathing zone. The PAPR, located at the user's belt, fi lters the air sucked in from the surrounding envi-
ronment; this air subsequently fl ows through an air hose into the protective hood. The resulting overpressure
prevents the intrusion of harmful substances into the breathing zone and, at the same time, provides high
user comfort during long-term wearing due to the lack of any need for respiratory fi lter resistance overcoming
while breathing. It provides protection against solid particles in the form of liquid and solid aerosols, gases and
vapours depending on the selected fi lter type.
Approval, certifi cation
The CA-28 Euromaski welder's hood has been approved in accordance with the requirements of the Euro-
pean standard EN 12941 Class TH2. All parts of the used system must be approved by the manufacturer and
used in accordance with the instructions provided in this user manual.
WARNINGS AND LIMITATIONS ON USE
• User must be properly informed about any hazards at the workplace and about safe usage of personal
protection devices before using the system. If you need any further information, please contact the
manufacturer or your distributor.
• The CA-28 Euromaski welder's hood must be used exclusively with the CleanAIR
CleanAIR ® compressed air systems. Please read this manual and also the user manual for the CleanAIR
PAPR or the CleanAIR ® compressed air system
• Do not use in confi ned areas, in an environment with insuffi cient oxygen supply (<17%), in an oxygen-
enriched environment (>23%) or in places with imminent hazard to human life or health.
• Do not use in environments where the user lacks knowledge about the kind of contamination and its
concentration.
• Do not use when the powered air purifying respirator is turned off or when the compressed air inlet is
closed! When the respirator is off or the compressed air inlet is closed the face shield fi ltration systems
provide little or none protection to the respiratory tract. It could also result in increased carbon dioxide
concentration or lower oxygen content inside the hood. If the PAPR or the CleanAIR
system ceases to operate during use due to any reason whatsoever, the user must immediately leave the
contaminated workplace.
• Negative air pressure may be generated inside the hood when inhaling during very exhausting work
resulting in lowering of the protective effect.
• The head section must always be correctly sealed to the face to provide maximum protection to the user.
Should beard or long hair get trapped in the sealing line, the resulting leakage could result in lower
protection level.
• Do not use when any part of the system is damaged. The head section and the air hose must be checked
before each use. Eventual cracks or leakages could negatively impact the required level of user protection.
• Scratched or otherwise damaged eye windows must be immediately replaced.
• Eye protection is provided by the built-in hood eye window and swivel-mounted welding fi lter, position of
which can be adjusted in the vertical direction. For recommended darkness levels for various applications
see Tables A and B
• Before you start welding you can look through the hood eye window, which provides effective
protection against harmful radiation. During welding you must look also through the swivel-mounted
welding fi lter, though.
• Observe the recommended working distance between the welder's hood and the welded material (min. 50 cm)
• If higher darkness level then DIN 12 is required, replace the standard welding fi lter with the VR-1 large
welding fi lter - it covers the whole viewing fi eld.
• Do not take the welder's hood off your head and do not switch off the PAPR or the CleanAIR
air system until you leave the contaminated workplace.
• Use only certifi ed original air fi lters designed for your fi ltration-ventilation unit. Change the air fi lters
whenever you can feel a change in the smell of the air coming from the unit.
