The Amerex 549 HT Series is a premium 3.75 lb Halotron® BrX (2-BTP) Clean Agent Fire Extinguisher featuring a flexible discharge hose and nozzle for improved fire suppression around sensitive electronics, machinery, and equipment located in confined or difficult-to-access areas.
Designed for Class B (flammable liquid) and Class C (energized electrical) fires, the Model 549 rapidly extinguishes fires while leaving no residue, helping prevent damage to valuable electronics and minimizing downtime. Unlike traditional ABC dry chemical extinguishers, Halotron® BrX evaporates after discharge, eliminating cleanup and contamination of sensitive equipment. The Model 549 is ideal for data centers, server rooms, telecommunications facilities, electrical control rooms, laboratories, healthcare facilities, museums, clean manufacturing environments, and other mission-critical applications. Manufactured in the USA, the HT Series features an all-metal valve, lightweight aluminum cylinder, stored-pressure design, a 6-Year Manufacturer Warranty, and a 12-Year Service Life.
