Protect-Air HoseGuard Air Safety Fuses

Designed to prevent hazardous hose whip incidents in compressed air systems, Protect-Air’s HoseGuard provides a layer of protection across a wide range of industrial applications. The compact device is designed to enhance workplace safety and provide compliance with international standards by automatically responding to air line failures.

In the event of a sudden increase in airflow — such as a ruptured or disconnected hose — the device instantly shuts off the air supply. This rapid response helps prevent hoses from turning into uncontrolled projectiles, a common cause of injuries in environments using pneumatic tools.

Key features include: automatic activation, factory preset to detect excessive airflow, without the need for manual intervention; a tamper-proof design, with no adjustments necessary post-installation, for consistent protection; and a maintenance-friendly, integral bleed hole that allows some air to flow through, which enables the line pressure to automatically reset the device once the main break is repaired.

Suitable for various applications, including manufacturing, mining, automotive workshops and cleanroom environments, the device is compliant with EN ISO 4414:2010 and the Machinery Directive 2006/42/EC.
