Part No. 5044
OPERATORS’ MANUAL

1. INTRODUCTION
The Stealth-G is designed to provide protection when the wearer is working in a contaminated
environment. The system is designed to supply clean air via the blower filter through a breathing
tube to the welding faceshield, so that the user can continue working. It is a combined face and
powered air purifying respirator (PAPR) system for increased safety and comfort during welding.
Please read these instructions carefully before unpacking. For proper use, see User Instructions or
contact your supplier for help.
2. APPROVALS
The system complies with the requirements of PPE Regulation 2016/425 and European Standard
EN 12941: 1998+A2:2008 class TH3 P R S L. The PAPR is designed to provide a supply of filtered
air via a breathing tube to a welding headpiece. The equipment can be used in environments that
requires a class TH3P breathing protection device and protects against particulate contamination.
All components used in this respiratory system must be manufacturer approved parts and must be
used in accordance with the instructions in this manual.
Notified Body:Vyzkumny ustav bezpecnosti prace, v. v. i.,Jeruzalemska 9 ,116 52 PRAHA 1,Country :
Czech Republic (Notified body number 1024).
• The approval is not valid if the product is incorrectly used together with non-approved
parts or components.
• Only the particle filter and pre-filter can be used together with this system. Filters from
other manufacturers should under no circumstances be used.

3. WARNINGS AND LIMITATIONS OF USE
Before each use, inspect the Stealth-G for damage and check it is fully operational and test the air
flow to verify it is providing an adequate volume of air.
Always wear the Stealth-G when working in a contaminated environment and do not remove the
head top or turn off the air filter unit until outside.
If you are not sure about the concentration of pollution, or about equipment performance, ask the
industrial safety engineer.
The manufacturer is not responsible for injury due to the following incorrect use or
incorrect choice of equipment.
WARNING:
This respiratory system should be used by experienced and qualified personnel only.
Before using, ensure you understand that at very high work rates the pressure in the system may
become negative at peak inhalation flow.
Before and during use, be aware of the possibility of looped hoses and/or cables becoming caught
up.
If the system is in the power-off state little or no respiratory protection is to be expected. Leave the
work place and remove the headgear when the system is in the power-off state – a rapid build-up
of carbon dioxide and depletion of oxygen within the hood may occur.
The filters shall only be fitted to the turbo unit and not directly to the helmet/hood.
The user should not confuse the markings on a filter relating to any standard other than EN 12941
with the classification of this device when used with this filter.
DO NOT use Stealth-G:
– With the blower unit switched off.
– In an atmosphere that is immediately hazardous to user hygiene or health and/or has oxygen
content of less than 19.5% or contains unknown substances.
– In an explosive atmosphere.
– In confined spaces or areas of poor ventilation.
– In high winds.
DO NOT:
– Alter or modify in any way.
– Touch any of the moving parts.
– Allow water or other liquids to enter the impeller chamber, the filter or battery compartment.

4.2 Installing the Battery/Charging
4.2.1 Slide the battery towards the back
of the filtration unit.
4.2.2 Make sure the battery is locked in
position.
4.2.3 The battery can be charged on the filtration unit or separately.
The battery is partially charged when delivered. It must be charged to 100% (4 bars)
before the first use.
It is recommended to charge the batteries to 100% before each use.
The charger must not be used for anything else than it was designed for.
Do not charge the battery in a potentially explosive area. The charger must only be
used indoors.
The charger regulates the charge automatically. Once the battery is fully charged, it
will maintain it at a 100% (floating charge).
The charge time is 3 to 4 hours.
The battery will discharge itself after long storage periods. Always charge the battery if
the device was stored for more than 15 days.
When the battery is new or has been stored for more than 3 months, charge it and
discharge it at least twice in a row to reach the nominal/rated charge capacity.

Battery charge:
1. Connect the battery to the charger. The connector is above the battery.
2. Connect the charger to the mains.
3. The state of charge is displayed via a red LED on the mains charger.
4. Once the charge is finished, the floating charge becomes active; the red LED switches
off and a green LED switches on.
5. Disconnect the charger from the mains (do not keep the charger plugged to the mains if
it is not in use).

The blower unit must be checked regularly and must be changed if it is damaged.
Filters must be changed if damaged, or blocked and does provide sufficient airflow.
The breathing tube must be changed if it is broken or creased.
The battery must be charged when the low battery alarm sounds.
Use a soft cloth to wipe the external surfaces. Do not use water.
Wipe the equipment with a disinfectant such as Dettol. Dilute the disinfectant with water to a
ratio of 1:99 and wipe the surface of the equipment with a clean lint-free tissue and the
solution. Then wipe the surface of the equipment with another clean lint-free tissue or cloth
and water.
The filter should be replaced together with the pre-filter.
8.1 Storage
The respiratory system must be stored in a dry, clean area in the temperature range of –10º
to +55º and relative humidity less than 90%.
If the equipment is stored at temperature below 0º, the battery must be allowed to warm up
to achieve full battery capacity. The equipment must be protected from dust, particles and
other contamination.
If the equipment is not used for a long time, the battery should be fully charged, removed
from respiratory system and stored separately.
Transport the equipment with original packaging box and away from direct sunlight.

11. MARKINGS EXPLANATION
Powered filtering device
• EN 12941:1998 Respiratory protective devices – Powered filtering devices incorporating a
helmet or hood – Requirements, testing, marking.
• TH3 P R (SL) classification of the unit. ‘TH3’ defines the level of protection, ‘P R’ indicates the
filter type (‘P’ = Particle filter, ‘R’ = Reusable type of particle filters) and ‘SL’ reflects the filter
has been tested against particles of liquid and solid matter.
Warning indication
This Stealth-G PAPR has sound and vibration alarm function.
Each square equals a period of 100ms. Grey is a beep sound and a blank square is a quiet period.
If several continued squares are in grey then there is a continuous beep sound.
Eg. When the current is overloaded, the system sounds like beep~beep~beep~~~~.
