KB3D Nexus: N40 (Modular GasMask System)

Baseline module for the KB3D Nexus system.

Developed in the KB3D lab, the Nexus is The Modular Gas Mask System. Built around a universal interface—dubbed The Insert—each module screws securely into the mask’s insert, allowing the function to be changed as required.

The Nexus: N40 Adapter module converts the Nexus front port to a standard 40 mm NATO thread, allowing compatibility with a wide range of accessories and devices. Whether for filters, hoses, valves, or other modular attachments, the N40 Adapter serves as the bridge between the Nexus ecosystem and external systems.

Included with a rubber umbrella valve, to set the direction of airflow. However this can easily be removed.

Gas mask not included.
