Protect-Air HoseGuard safety fuses for compressed air applications

Protect-Air HoseGuard safety fuses offer simple and efficient protection to pneumatic systems in the event of a broken compressed air hose or pipe. They immediately shut off the air supply should the volume of air exceed a set value.

If the air consumption exceeds the set value - such as when a compressed air line is severed - an internal piston instantly shuts off the main flow. An integral bleed hole allows some air to flow through. This enables the line pressure to automatically reset the fuse once the main break is repaired.

The safety fuses are available in aluminium and, on special order, 316L stainless steel. They are suitable for any application where compressed air is used, including manufacturing facilities, mining, the chemical and pharmaceutical industries, machinery hire, fuel station air hoses, trade show venues, automotive workshops and cleanrooms.

The safety fuses meet OSHA and MSHA requirements and are CE compliant to help Australian managers comply with Workplace Health and Safety Act directives. They comply with EN ISO 4414-11.2010-§5.4.5.11.1: Failure of hose assemblies and plastic piping: When failure of a hose assembly or plastic piping constitutes a whiplash hazard, it shall be restrained or shielded by suitable means.
