General description

Install a flash arrestor downstream of a hydrogen gas cylinder (see figure), or a hydrogen generator. In event of a flashback, the flash arrestor diverts the flame into three feet (1 m) of tubing, where the flame is extinguished and the heat is absorbed. The shock wave preceding the flashback closes and locks the arrestor′s shutoff valve, eliminating the flow of gas. Inlet/outlet fittings are 1/4 in. female NPT. For use to 50 psig (3.5 kg/cm²). Meets Occupational Safety and Health Administration (OSHA) and National Fire Protection Agency (NFPA) codes. Factory Mutual approved.
