Lightning Strike Protection: The Preventor

preventor-2005A-home-lightning-protection-deviceThe Preventor is a state of the art, mast-mounted air terminal which transmits ions into the atmosphere. This device is designed to activate in the moments preceding a direct lightning strike. It creates a stream of charged ions which carries ground charges and reduces electrical tensions while clouds are overhead, reducing the possibility of a strike. The ESE air terminal also incorporates the direct path to ground protection of a conventional lightning system. If a strike does occur, the device safely grounds the charge through a conductive streamer – preventing damage to property. When your house is struck by lightning, you know the Preventor works. See a customer video testimonial.

The greatest accomplishment of the ionizing conductor is that the Preventor 2005 can protect most buildings of any height with a single system properly installed to HBP-21 Level II Manufacture Standards.  A second product (2005A) is available for smaller residences or for use with specific architectural designs.

The components we use for lightning/surge protection systems are UL and ARL Listed and Labeled.  Completed systems may now also be inspected and certified by UL or ARL – Applied Research Labs (NRTL). As UL Listed installers with demonstrated compliance history, Florida Lightning Protection can request a UL inspection to document system compliance when required.
