Helmet Flowhood 5

064286

EC Type-examined by Berufsgenossenschaftliches Institut für Arbeitssicherheit, D- 53754 Sankt Augustin, Germany, ID: 0121.

1. General

oThe 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.

oThe Flowhood 5 consists of a helmet, a visor and a breathing hose.

oThe Flowhood 5 is connected to the blower unit Proflow2, Proflow2 SC, Proflow3, Proflow2 Ex,

Autoflow 120A or Autoflow 120 Ex.

oAir 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

2.1The 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.

2.2The 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).

2.3The filtering device may be used only if the oxygen content of the air is 18 - 23 vol.%.

2.4Gas filters do not protect against particles. Similarly, particle filters do not provide protection against gases or vapours. In case of doubt, use combined filters.

2.5Normal filtering devices do not protect against certain gases such as CO (carbon monoxide), CO2 (carbon dioxide) and N2 (nitrogen).

2.6Particle filters are allowed only for single use if they are applied against radioactive agents, micro- organisms (virus, bacteria, fungi and spores) or enzymes.

2.7It is likely that adequate protection cannot be guaranteed if the user’s beard, hair, spectacle frames or clothing intrude into the faceseal.

2.8When 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.

2.9The 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.

2.10At a very intense working pace, the pressure in the facepiece can change into negative pressure at peak inhalation.

2.11Conditions -10 °C...+50 °C, relative humidity (RH) under 75 %.
