Product Description

These Ansul Sentry Purple-K fire extinguishers are used to combat fires involving flammable liquids, gases and greases (Class B) including such fires when involved with energized electrical equipment (Class C). This agent is widely used in the petroleum industry and in other areas where the fire risk is high. Purple-K is at least 4 to 5 times more effective in extinguisher applications than carbon dioxide and more than twice as effective as sodium bicarbonate-based extinguishers. This agent is approved or listed by nationally recognized testing laboratories and meets U.S. and Canadian government specifications.

  • Ansul Purple-K extinguishing agent. Refill: item # 09454.
  • Seamless, welded steel shell hydrotested to 600 psi (41 bar).
  • Tough, polyester-urethane powder paint.
  • Extruded aluminum valve, plated steel valve stem, steel pick-up tube, plated steel ring pin, standard CO2 hanger hook.
  • Large color-coded pressure gauge.
  • Listed/Approved by UL, DOT, USCG (with proper bracket).

Note: There is a $250 minimum order on Ansul extinguishers (mix and match any Ansul extinguishers; other items in your order do not count towards this minimum order). Our e-commerce system does not have a capability to handle that, so be aware that while you can order say, just one 2.5 lb Ansul extinguisher, we can't sell you just one. We can, however, supply Amerex brand extinguishers with no minimum order.

Application Note 1: This extinguishing agent is incompatible with strong acids, monoammonium dihydrogen phosphate (also called "ammonium phosphate", NH4H2PO4), sodium-potassium alloy (NaK) and/or lithium metal; consult the Safety Data Sheet (SDS) for Purple-K for details.

Application Note 2: Paragraph 4.4.1 of the 2017 edition of NFPA 10 requires that all dry chemical stored pressure fire extinguishers manufactured prior to 1984 be replaced immediately. Paragraph 4.4 declares that all extinguishers, regardless of type, manufactured prior to 1955 are obsolete as they were tested to obsolete standards and rating systems.
