Please read and follow the instructions below to ensure your safety. If you have any questions, please contact your
dealer or optrel. Please retain this manual for future reference. The compressed air device may only be used for
the purpose stated in this manual.
1. Introduction
The suppliedair supplies an approved welding helmet or a grinding helmet (protective helmet) with fitered fresh air.
When used correctly, the user is protected against dust and particles from the outside air. The air is taken from a
compressed air source (compressor or air hose system) and is conneted to the suppliedair unit. The airflow can be
regulated on the suppliedair and directed into a protective mask or hood. The overpressure prevents contaminants
from entering the breathing zone. At the same time, this slight overpressure ensures comfortable wearing (even
during long periods of use).
suppliedair warns the user with a short whistle as soon as operating pressure falls below the limit. The air introduced
into the suppliedair must be hygienically clean and comply with the EN 12021 standard (breathable air). If the air does
not meet this requirement, install the suppliedair Conditioner between the suppliedair and the compressed air source.
The quality of the air at the outlet of the suppliedair Conditioner complies with EN 12021 when the unit is used in the intend-
ed temperature range (see chapter 10). The air from the compressor must meet the requirements in Chapter 1.1 corre-
spond. The suppliedair Conditioner removes oil ist,,odours and aromas. Two users can be connected to one filter station.
The suppliedair Conditioner does not remove carbon monoxide (CO) or carbon dioxide (CO2) from the air.
The suppliedair Conditioner does not remove carbon monoxide (CO) or carbon dioxide (CO2
) from the air!!!
1.1. Requirements for compressed air supplied from the compressor
• The suppliedair Conditioner can only be connected to compressor which supplies air at an oxygen concentration of
20 % to 22 % vol
20 % to 22 % vol. The carbon dioxide concentration must not exceed 500 ppm and the carbon monoxide con-
centration must not exceed 15 ppm.
• The maximum concentration of water in the air may be 50 mg/m³ at the rated pressure of 1 to 20 MPa.
The humidity of the suppliedair must be controlled to prevent the unit from freezing.
2. Limitations on use
Before using the system, the user must become fully familiar with possible risks in the workplace, and be fully
informed of the safe use of the personal protective equipment. In case of any doubt, please contact the manufac
-
turer or your local distributor. Suppliedair systems must be used exclusively with with the headboard listed in this
manual. Therefore read this manual in conjunction with the user manual of your suppliedair Headtop.

fall and result in decrease in the protection factor.
• The use of oxygen-enriched air and oxygen is forbidden in the suppliedair system due to the risk of explosion.
• The system may only be used in environments with a small probability of damage to the supply hose and where
the user’s movement is not limited.
•
If, in addition to suppliedair, another accessory (e.g. a spray gun) is connected to the compressed air supplyy
•
the user must make sure that a sufficient air flow to the hood is secured even at the maximum air consumption
by this accessory.
•
If the unit is used in environments with high temperatures, the supply hose must be resistant to such effects.
• It is forbidden to use the unit in explosive environments.
•
Before every use of the unit, check that the air flow is higher than the minimum value specified in the
