H3R Performance manufactures high quality, UL Listed fire extinguishers under the HalGuard™ and MaxOut™ brands. HalGuard™ "clean agent" extinguishers do not leave a messy residue. MaxOut™ is a reliable line of dry chemical extinguishers. Both are effective on flammable liquid fires and do not conduct electricity - two important considerations when dealing with the types of fires most likely to occur in an automotive environment. HalGuard™ and MaxOut™ are available in a variety of sizes in rechargeable chrome-plated, red or black bottles. They sport high quality steel cylinders, all metal valve construction, and aviation-quality mounting brackets.
