150 lb. Regulated Pressure Sodium Chloride and 250 lb. Regulated Pressure Copper Powder — two choices for large volume Class D (flammable metal) protection. Model 680 (Sodium Chloride) is effective on magnesium, sodium, potassium, and sodium potassium alloy fires. Model 681 (Copper Powder) designed specifically for fighting difficult lithium fires. Well balanced for quick transport on 36″ non-sparking rubber tread steel wheels. Both wheeled fire extinguishers are pressurized with Argon and regulated to a low 125 psi to avoid disrupting the burning materials.
