Introduction

Softhood is a personal respiratory protection system based on the principle of creating an overpre-

ssure of filtered air in the breathing zone. The e3000X respirator filters the air extracted from the 

environment and then releases it into the protective hood The overpressure prevents contaminants 

from entering the breathing zone. This mild overpressure ensures the wearer’s comfort, even with 

long-term use Breathing remains easy because the user does not have to overcome the resistance 

of the filter. The head piece can also be used with the suppliedair, which operates on the principle of 

supplying air from locations with clean air

All softhoods in this user manual provide respiratory protection (in combination with e3000x or 

suppliedair) and face protection against high velocity particles and low energy impact  In addition, 

the softhood also provides chemical resistance The material of softhood is resistant to acids, alkalis, 

and organic substances

If not sure about the suitability of the hood for a specific application, consult with the manufacturer 

or your supplier!

Limitations on use

1  Never use the hood in the following environments and under the following conditions:

• 

If oxygen concentration in the environment is lower than 17 %.

• 

In oxygen-enriched environments.

•  In environments where the user lacks knowledge about the type of dangerous substances 

and their concentration

•  In environments that represent an immediate danger to life and health

2  If the protection foil is damaged, replace it immediately
3 

The hood does not protect against hard shocks, explosions or corrosive substances.

4  Move to a secure location and take appropriate measures when any of the following problems 

occur while using the hood:

• 

If you feel a significant increase in breathing resistance or any other problems with bre

-

athing

• 

If you experience stench, irritation or an unpleasant taste while breathing.

• 

If you feel unwell or experience nausea.

5 

Use certified original filters designed for your powered air purifying respirator only. Replace 

filters every time you detect the change of odour in supplied air from the respirator.

6 

Filters designed for capturing solid and liquid particles (particle filters) do not protect the user 

against any gases Filters designed for 

capturing gases 

do not protect the user against any 

particles. In the workplace contaminated with both particles and gases, combined filters must 

be used

7  The material of the hood can cause allergic reactions to sensitive persons
8  Pay attention to check the product before use Do not use, if any part of the system is da-

maged

9 

Don’t put the hood on a hot surface.

10  This product is intended for use in environments with a temperature range of 0 °C to + 60 °C with 

relative humidity of 20 - 95 % Rh.

The lifetime of the hood and visors is influenced by many factors such as cold, heat, chemicals, 

sunlight or incorrect use The hood should be checked on a daily basis of possible damage of its in-

side or outside the structure Careful use and correct maintenance of the protective hood enhances 

operating life and improves your safety!

Checking before use:
Inspect that every part of the hood is undamaged and installed correctly

Cleaning and desinfection:
•  After each work shift, clean the head section, inspect each part, and replace any parts that 

are damaged

•  Cleaning must be done in a room with adequate ventilation Avoid inhaling harmful impurities 

that have settled on the individual parts!

•  To clean, use lukewarm water with soap or another non-abrasive detergent and a soft brush (it 

is not recommended to use other detergents or solvents)

•  After cleaning individual parts with a damp cloth, you must rub them dry or leave them to dry 

at room temperature

•  Cleaning with acetone or other solvents can damage the product and lose its protection

• 

For disinfection, disinfect with a clean, soft cloth and disinfectant solution (for example a 1% 

chlorine solution with 10,000 ppm available chlorine) Alternatively, a combined detergent / 

disinfectant can be used 

Visor protective foils
Hoods are supplied with a foil protecting the visor against damage during handling and transport 

The foil is sewn in the hood and it must be removed carefully
A separately supplied foil 0,1 mm thick is designated to protect the shields of these hoods after 

the removal of original foil To attach it to the shield, the foil is provided with self-adhesive tapes 

on the sides

Protective foil replacement:
•  Peel off the old foil, wipe the hood visor with a damp cloth to remove the impurities from it

•  Remove the protective paper from the self-adhesive tape and stick the foil on the shield

Headband adjustments
1  Set the depth of the headgear by resetting the top headband The ideal position of the headge-

ar is where the sweatband sits slightly above the level of the eyebrows

2 

Set the headgear so that it fits firmly on your head:

•  By turning the rear wheel
•  Basic headgear: resetting the front headband

3  Set the optimal distance between the nose and visor to 2 cm Reset the position of the rails on 

both sides of the headgear (see the pictorial annex on the end of the manual).
