Automatic darkening welding mask with digital filter and PAPR system

FS1 with PAPR A6 combines a welding helmet with a powered air-purifying respirator, designed for working environments where welding fumes, airborne metal particles and dust may be present.

The PAPR (Powered Air-Purifying Respirator) system filters ambient air and delivers it through a breathing tube into the helmet's breathing zone. This combines eye and face protection with a supply of filtered air.

The PAPR A6 features intelligent airflow control, automatically adjusting blower performance to help maintain the selected airflow as filter resistance increases.

Users can choose between three airflow settings: 170, 190 and 230 L/min.

The system uses a TH3 P R SL particulate filter, with a supplier-stated filtration efficiency of more than 99.99% under specified test conditions.

A 14.8 V / 2.6 Ah lithium-ion battery provides extended operating time and can be fully recharged in approximately 3 hours.

The ergonomic belt and shoulder strap, air distribution diffuser and audible, visual and vibration alarms support comfortable and safer operation.

Features & Additional Information

TH3-Class Respiratory Protection

The PAPR A6 uses a TH3 P R SL particulate filtration system.

According to the supplier, the filter achieves more than 99.99% filtration efficiency under specified test conditions.

The system is intended to reduce exposure to airborne particles, including suitable particulate components of welding fumes.

Important: particulate filtration does not provide universal protection against harmful gases such as carbon monoxide or ozone.

Three Adjustable Airflow Levels

The system provides three selectable airflow settings:

Airflow can be selected according to the working conditions and user requirements.

Intelligent Airflow Regulation

The automatic airflow control system adjusts blower performance as filter resistance increases.

This helps maintain the selected airflow within the system's operating capability.

Air Distribution Inside the Helmet

A specially designed air diffuser distributes filtered air throughout the helmet's breathing zone.

Filtered air is delivered from the blower unit through a flexible breathing tube.

Multi-Stage Filtration

The system incorporates several protective components:

• Pre-filter – captures larger particles and helps extend the main filter's service life.

• Main particulate filter – captures fine airborne particles.

• Spark protection – reduces the risk of hot particles reaching and damaging the filter system.

• Filter cover – holds the filter securely in place.

Filters must be replaced according to the manufacturer's instructions and their condition.

Rechargeable Lithium-Ion Battery

The system uses a 14.8 V / 2.6 Ah / 38.48 Wh Li-ion battery.

Key features include:

• approximately 10 hours of operation under supplier-stated conditions;

• approximately 6 hours at the maximum 230 L/min setting;

• approximately 3 hours for a full recharge;

• more than 500 charging cycles, as stated by the supplier.

Actual runtime depends on airflow setting, filter condition, temperature and battery age.

Audible, Visual and Vibration Alarms

The PAPR A6 includes three warning methods:

• audible alarms;

• visual indicators;

• vibration alerts.

These are designed to alert the user to system status and possible operating problems.

Refer to the manufacturer's instructions for the meaning of individual alarms.

Ergonomic Carrying System

The blower unit is worn using a padded belt and shoulder strap.

This helps distribute the equipment's weight and improve comfort during extended use.

Applications

The FS1 with PAPR A6 is designed for work requiring a combination of welding helmet protection and filtered air delivery:

• metal fabrication and welding;

• industrial welding operations;

• metal repair and maintenance;

• welding workshops;

• metalworking tasks generating airborne dust;

• workplaces where particulate-filtering respiratory protection has been assessed as suitable.

The system must be selected according to workplace risk assessment, contaminant type and manufacturer instructions.
