Nitrogen Cylinder Operated - 125/150, 300/350 lb. Direct Pressure ABC, Regular, Purple K Dry Chemical
125 lb. ABC & Purple K and 150 lb. Regular Direct Pressure extinguishers utilize a 23 ft3 nitrogen cylinder with a “quick opening brass valve” to pressurize and completely discharge the agent cylinder. The compact size and 16" semi-pneumatic tires allow easy maneuvering and operation by one person, through narrow doorways and aisles. A 4" stainless steel fill opening with rugged chrome plated brass cap makes servicing easier. For large hazards choose the 300 lb. ABC or Purple K or 350 lb.
