Australia: The Procap has been designed to conform with AS/NZS 1716:2003. Licence 0858 by SAI Global, Australia.
1. General
The Procap powered air helmet is designed to be used together with a powered blower device and
Þ lters to protect the respiratory system and face against hazardous gases and particles.
The Procap consists of a helmet, a ß ip-up face shield and a breathing hose.
The Procap Weld has in addition a secondary welder's shield which slides over the top of the primary
face shield.
The helmet contains a head harness, an airduct, a brow seal and a hose socket. The purpose of
o
the brow seal is to seal the visor frame against the helmet so as to let a slight overpressure build
up inside the face shield.
The face shield contains a visor frame, a visor, two wheel carriages and a face seal. The purpose
o
of the face seal is to seal the visor frame against the face so as to let a slight overpressure build up
inside the face shield.
The welding shield contains a frame, two wheel carriages and a welding Þ lter.
o
The Procap is connected to the blower unit Proß ow or Autoß ow. Air is drawn through particle Þ lters
o
connected to the blower by an electronically-controlled fan, and led through the breathing hose into
the facepiece.
The Procap allows the use of specially designed hearing protectors (see accessories list).
o
Procap can be connected to the T/A/LINE pressure regulator.

2. Limitations of use
2.1 The Þ 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 Þ ltering device must not be used in restricted spaces (e.g. cisterns, tunnels) because of the
risk of oxygen deÞ ciency or presence of heavy oxygen-displacing gases (e.g. carbon dioxide).
2.3 The Þ ltering device may be used only if the oxygen content of the air is 18 - 23 vol.%.
2.4 Gas Þ lters do not protect against particles. Similarly, particle Þ lters do not provide protection
against gases or vapours. In case of doubt, use combined Þ lters.
2.5 Normal Þ ltering devices do not protect against certain gases such as CO (carbon monoxide), CO
(carbon dioxide) and N
2.6 Particle Þ 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 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 Procap is permitted when connected to an intrinsically safe (explosion
proof) blower device.
2.9 The blower or T/A/LINE must be running while using the respirator. If the blower or T/A/LINE
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 Recommended operation conditions: -10 °C...+50 °C, relative humidity (RH) under 75 %.
