1. General
The hood Flowhood 1 and Flowhood 2 is designed to be used together with a powered blower
device and fi lters to protect the respiratory system and face against hazardous gases and particles.
o The Flowhood 1 & 2 consists of a hood and a breathing hose.
o Air is drawn through particle fi lters 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 fi ltering device must not be used if the environment and contamination are unknown. In
case of doubt, isolating respirators (air supply) which function independently of the atmosphere
must be used.
2.2 The fi ltering device must not be used in restricted spaces (e.g. cisterns, tunnels) because of the
risk of oxygen defi ciency or presence of heavy oxygen-displacing gases (e.g. carbon dioxide).
2.3 The fi ltering device may be used only if the oxygen content of the air is 18–23 vol.%.
2.4 Gas fi lters do not protect against particles. Similarly, particle fi lters do not provide protection
against gases or vapours. In case of doubt, use combined fi lters.
2.5 Normal fi ltering devices do not protect against certain gases such as CO (carbon monoxide),
CO (carbon dioxide) and N

2.6 Particle fi lters are allowed only for single use if they are applied against radioactive agents or
micro-organisms (virus, bacteria, fungi and spores).
2.7 It is likely that adequate protection cannot be guaranteed if the sealing edge (face seal) of the
facepiece is obstructed by the user's beard, hair, spectacle frames or clothing.
2.8 When a breathing protector is used in explosive atmospheres, please follow the instructions
given for such areas. The use of Flowhood 1 & 2 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 %.
3. Start-up
See Instructions for Use of the blower device to be used and of the fi lters. Only use Pro2000 fi lters.
•
Check intactness of hood and breathing hose.
•
Fix the breathing hose of the hood tightly to the blower device.
•
Screw the fi lters tightly to the blower device.
•
Remove the protective fi lm from both surfaces of the visor.
•
Adjust the headband (velcro).
