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).
