Powered Air Protection with the RPB PX5

The supplied RPB PX5 PAPR delivers a constant flow of filtered air, helping to improve breathing comfort while protecting against airborne particles commonly generated during welding and grinding. Built for reliability and durability, the PX5 incorporates advanced powered air technology that enhances both user protection and day-to-day comfort in challenging working conditions.

Superior Optical Performance

The large auto-darkening welding lens is rated Optical Class 1/1/1, providing outstanding visual clarity with minimal distortion. This allows for accurate weld placement, improved visibility and reduced eye fatigue when working from different positions or viewing angles.

Advanced Airflow Management

An intelligent dual-airflow design improves both comfort and visibility. Around 75% of filtered air is directed towards the breathing zone, while the remaining airflow is channelled across the visor to help prevent condensation and maintain a clear field of vision throughout the job.

Designed for Comfort

Weighing approximately 805g, the Z4 helmet has been developed to minimise strain during long working shifts. Its adjustable head suspension system provides a secure, balanced fit that moves naturally with the wearer, helping to reduce pressure on the neck and shoulders while improving overall comfort.
