HoseGuard ®
The HoseGuard offers simple but effective protection against pneumatic systems in the event of a broken compressed air hose or pipe. The air supply is immediately shut off by the HoseGuard, should the volume of air exceed a set value. This “value” is factory pre-set and is set to allow normal air consumption when using air tools, but will react instantly when the pre-set level is breached to protect all personnel and equipment that are near.
