1.2 About the product
FreshAir (FA) is a respiratory protective system which is based on the
principle of circulated pressurized air in the hood. A supply of clean, filtered
breathing air creates positive pressure inside the headpiece, which prevents
the external contaminated air from entering the user’s breathing zone.
A suitable compressed air source complying to EN 12 021 standard and
supplying hygienically clean breathing air, can be connected to the FA
Pressure Flow control valve. If the air does not comply with this standard,
install the FA Pressure Conditioner filtration unit before the FreshAir Pressure
Flow Control valve unit.
FA Pressure Flow Control is equipped with a pressure gauge for checking
the input pressure. The air at the outlet of a FA Pressure Conditioner filter
unit complies with EN 12 021 standard, if it is used within the temperature
range 10 – 60 °C and the air from the compressor complies with the
requirements explained later in this manual. Up to two users can be
connected to the FA Pressure Conditioner filtration unit.
NOTE: FreshAir Pressure Conditioner does not remove carbon monoxide (CO)
and carbon dioxide (CO₂).
