A replacement blower filter unit for the extremely popular range of Weltek air fed helmets.


Please note:  Blower is supplied as bare unit.  Battery and filters not included.



When used with the Weltek range of air fed masks, the Airkos®, blower unit provides filtration of Solid and Liquid Particules (PSL) associated with welding and grinding fumes. The main filter on the Airkos® is classified as re-usable (PRSL), and does not need to be replaced after every shift. The visual and sound alarm will inform the operator when to replace the filter.
The PRSL filter of the Airkos® is equipped with a pre-filter, blocking the largest particles and extending the lifecycle of the main filter. As an option, a pre-filter with active charcoals is available.
The Airkos® blower unit (PAPR) is approved and certified according to the EN 12941 standard, with and only with the Weltek helmet.

Completing the alarm for the clogged filter, the filtration unit is also equipped with a distinctive alarm for the battery, informing the operator when the charge is running low.

The Airkos replacement blower is supplied without a battery. Standard and heavy-duty batteries are also available. When equipped with the standard battery (Part Number CR7020), the Airkos® can provide up to 10 hours of operating time (with a new filter and on minimum airflow). Once equipped with the heavy-duty battery (Part Number CR7021), the Airkos® offers up to 15 hours, under the same conditions.
