Helmet Flowhood 5
064286
EC Type-examined by Berufsgenossenschaftliches Institut für Arbeitssicherheit, D- 53754 Sankt
Augustin, Germany, ID: 0121.
1. General
o The helmet Flowhood 5 is designed to be used together with a powered blower device and
filters to protect the respiratory system and face against hazardous gases and particles.
o The Flowhood 5 consists of a helmet, a visor and a breathing hose.
o The Flowhood 5 is connected to the blower unit Proflow2, Proflow2 SC, Proflow3, Proflow2 Ex,
Autoflow 120A or Autoflow 120 Ex.
o Air is drawn through particle filters connected to the blower, by an electronically-controlled fan
and led through the breathing hose into the facepiece (airduct). Exhaled air exits through an
exhalation valve found in the lower part of the hood.
2. Limitations of use
2.1 The filtering device must not be used if the environment and contamination are unknown. In
case of doubt, insulating respirators which function independently of the atmosphere must be
used.
2.2 The filtering device must not be used in restricted spaces (e.g. cisterns, tunnels) because of
oxygen deficiency or presence of heavy oxygen-displacing gases (e.g. carbon dioxide).
2.3 The filtering device may be used only if the oxygen content of the air is 18 - 23 vol.%.
2.4 Gas filters do not protect against particles. Similarly, particle filters do not provide protection
against gases or vapours. In case of doubt, use combined filters.
2.5 Normal filtering devices do not protect against certain gases such as CO (carbon monoxide),
CO
2
(carbon dioxide) and N
2
(nitrogen).
2.6 Particle filters are allowed only for single use if they are applied against radioactive agents, micro-
organisms (virus, bacteria, fungi and spores) or enzymes.
2.7 It is likely that adequate protection cannot be guaranteed if the user’s beard, hair, spectacle
frames or clothing intrude into the faceseal.
2.8 When a breathing protector is used in explosive atmospheres, please follow the instructions
given for such areas. The use of Flowhood 5 is permitted when connected to an intrinsically
safe (ex) blower device.
2.9 The blower must be running while using the respirator. If the blower turns off by accident, the
device ceases to function as a respirator, and carbon dioxide levels may instantly rise. This is
considered an abnormal situation.
2.10 At a very intense working pace, the pressure in the facepiece can change into negative pressure
at peak inhalation.
2.11 Conditions -10 °C...+50 °C, relative humidity (RH) under 75 %.
