2.1 Facepiece with Positive Pressure
Mask with Positive Pressure
See position 1a, Fig. 1.
The face blank is made of a special soft rubber compound and assures a snug, comfortable fit and
a tight seal.
The inhalation air flows from the connector of the mask past the inhalation valve to the inside of
the lens (thus keeping the lens largely fog-free) and then through the check valves into the nose
cup. The exhalation air passes through the spring-loaded exhalation valve to the ambient air.
The mask is approved according to EN 136. The available masks are approved for use at
temperatures between -30 °C / -40 °C and +60 °C depending on the mask.
For additional information see mask manual.
Mask-Hood-PS with Positive Pressure
See position 1b, Fig. 1.
The PremAire Mask-Hood consists of a positive pressure full face mask (3S type) with a connec-
tion for the lung governed demand valve (LGDV) AutoMaXX AS, a hood and an easy-to-handle
harness. The harness is located on the outside of the hood for better reach.
The hood covers the neck area and offers an additional seal. A tension ring inside the hood keeps
the hood open when folded to ease donning.
The inhaled air flows from the connector of the mask-hood past the inhalation valve to the inside
of the lens (thus keeping the lens largely fog-free) and then through the check valves into the nose
cup.
The exhaled air coming out of the exhalation valve flushes the hood and then streams out of the
neck opening to the ambient atmosphere. This flushing provides a slight positive pressure inside
the hood.
The face blank is made of a special soft rubber compound and assures a snug, comfortable fit and
a tight seal. The mask-hood is approved for use at temperatures between -40°C and +60°C.
For additional information see mask-hood manual.
2.2 Lung Governed Demand Valve

2.3 Automatic Switch Valve (ASV)
See position 3 and 4, Fig. 1.
The Automatic Switch Valve (ASV) switches automatically depending on the pressure of the
supplied air between the compressed airline breathing apparatus and the SCBA/Escape device
without interruption of the air supply.
The ASV can provide air according to EN 12021 for the user from two different air sources
(compressed air cylinder and e.g. ring line system).

2.6 Compressed Air Cylinder
See position 7, Fig. 1.
The compressed air cylinders are applied as breathing air cylinders with a service pressure of
200 bar and 300 bar, respectively.
The compressed air cylinders are qualified for filling with breathing air according to EN 12021.
The compressed air cylinders are manufactured and CE-marked in accordance with the require-
ments of the Pressure Equipment Directive 2014/68/EU. The assembly group (compressed air
cylinder and cylinder valve) is controlled according to the conformity assessment procedure of
Module H (full quality assurance) of Directive 2014/68/EU by the notified body:
DEKRA (Reg-No 2266), Handwerksstr. 15, 70565 Stuttgart.
The certified compressed air cylinders are listed in the EC-Declaration of Conformity.
All combination valve assemblies are fitted with a water tube or with an excess flow valve. The
excess flow valve delivers a restricted amount of compressed air in case of a fracture of the
cylinder connector to safely prevent the dangerous rebound.
2.7 Quick-Fill Adapter (Optional)
See position 12, Fig. 1.
The Quick-Fill Adapter is screwed into the cylinder filling port. For permanent attachment a
fastening torque of 10 Nm is recommended. It is accessible after removing the protection cap.
The Quick-Fill System permits a quick refilling of the compressed air cylinder, while the SCBA may
still be in use. Due to the non-return valve it is not possible to provide air. Only receiving air is
intended!
WARNING!
Do not grease the Quick-Fill couplings. Contact with oil, grease and other chemicals must be
avoided.
WARNING!
If, during filling, a leak occurs, filling must be stopped.
2.8 Compressed Air Supply Hose
See position 14, Fig. 1.
The compressed air line breathing apparatus is available in the standard lengths of 5, 10, 20, 30
and 50 m. The hoses are fitted with a one-hand safety coupling and can be connected to each
other.
Total length should be no more than 50 m. Compressed air supply hoses may be connected to
each other. The couplings can also be connected while under pressure.
Maximum number of compressed air supply hoses: 5
The permitted working pressure in the compressed air supply hoses is 6.0 to 8.5 bar.
The compressed air supply hoses are:
• flexible
• extremely crush-resistant and kink-resistant,
• heat-resistant (identified by the letter “H”),
• flame-resistant (identified by the letter “F”),
• antistatic (identified by the letter “S”),
and they can therefore withstand the high stresses to which they may be subjected in industry and
mining.
