Just pump in new air!
The refill valve of the EcoBlast air horn lets you recharge using a Mini Air Pump or any bicycle pump, service station air pump or air compressor. In seconds, Eco Blast is again ready to emit a powerful 120 db signal that meets all U.S.C.G. requirements. Eco Blast beats out chemical horns, too, because it operates in all weather and temperature extremes… can be safely stored or used near a heat source… works in any position… and leaves no rust rings on surfaces. Plus, with EcoBlast there's no worry about a potentially harmful chemical escaping into the environment.
Includes Air Horn and Hand Pump.
