HoseGuard Air Fuse


HoseGuard® - Hose whip protection for your personnel, equipment and machinery. The HoseGuard® is an efficient solution against hose whipping due to a severed hose. If a hose breaks, the air supply is reduced immediately to prevent the hose lashing uncontrolled around. The HoseGuard®is actuated through the increased difference of the flow when a burst occurs. Once activated some residual low flow will be present, this is to ensure a smooth reset once the hose has been repaired and reconnected.

Should the air consumption exceed the set value, e.g. the air line is severed, then the internal piston instantly shuts off the main flow. An integral bleed hole allows some air to flow though. This enables the line pressure to automatically reset the HoseGuard once the main break is repaired.
