Avon proudly introduces HMK150, a revolutionary Helmet Mask Kombination System specifically designed for CBRN and Riot Control.


HMK150, One Mask, Two Modes, Seamless Protection

Avon has teamed with Schuberth to provide flawless integration of their HM50 to the Schuberth P100N Helmet.


Based on the widely deployed 50 Series mask platform, the HM system brings the pedigree of a mask proven for use in the harshest environments and is CE marked for CBRN Protection.


By a simple exchange of the harness for the helmet connecting straps, the mask converts to be compatible with a world leading Police helmet for use in non-CBRN environments which is approved to the most advanced German Police specification.  The full face respirator is connected to the helmet in seconds, as there is no need for the helmet to be removed.  Respiratory protection is seamless.

The Avon HMK150 uses advanced technology acquired from the widely deployed 50 series to produce a full face mask that is designed and approved for dual wear modes. Dual modes allow the mask to be integrated with a standard head harness or converted to riot control mode when connected to a helmet. In riot control mode the full face respirator can be rapidly donned using fasteners which attach the full face mask directly to the Schuberth P100N Police helmet without the need to remove the helmet first. Importantly, the HMK150 system ensures the users head remains protected at all times during donning / doffing of the full face respirator whilst providing protection from riot agents when donned.

With the appropriate filter, the HM50 provides high level CBRN protection including chemical warfare agents, toxic industrial chemicals (TICS), toxic industrial materials (TIMS), biological and radiological hazards and riot agents.
