30LB Ansul Redline Cartridge (High Flow) (Purple K)

The Ansul Red Line HF-I-K-30-G (Part No. 418280) is a 30 lb High Flow cartridge-operated hand-portable fire extinguisher charged with Purple K (potassium bicarbonate) dry chemical. The "HF" designation signifies a high-flow nozzle configuration that delivers agent at a significantly higher mass flow rate than standard Red Line models — 0.99 lbs per second compared to the standard model's lower rate. Per NFPA 10, high flow extinguishers have been specifically designed for pressurized flammable liquid fires and pressurized gas fires, as well as other special hazards where agent flow rate is critical to extinguishment.

Rated 120-B:C, the HF-I-K-30-G combines Purple K's superior per-pound effectiveness on Class B fires with the high-flow delivery system, making it the highest-performance 30 lb hand-portable BC unit in the Red Line family. With a 30-foot effective range and 51.5 lb charged weight, it provides both the reach and the agent mass to address large-scale flammable liquid fires from a safe standoff distance. Every unit includes an Indicator Fill Cap and a Corrosion Resistant Cap as standard features.

Why High Flow Matters for Pressurized Liquid Fires

Standard extinguisher flow rates are effective on pool fires and spill fires where the burning fuel is at atmospheric pressure. Pressurized flammable liquid fires — such as those involving pressurized fuel lines, hydraulic systems under pressure, or LPG leaks — present a different challenge. The pressurized fuel stream continuously feeds the fire faster than a standard flow rate can knock it down. The HF-I-K-30-G's 0.99 lb/sec flow rate overwhelms the fuel supply rate, achieving knockdown that a standard-flow unit of the same agent capacity cannot reliably accomplish.

Included Features

• High Flow Pressure: Factory-configured high-flow nozzle delivers 0.99 lbs/sec — significantly higher than the standard Red Line configuration — specifically engineered for pressurized liquid and gas fire hazards per NFPA 10.
• Indicator Fill Cap: Red stem indicator pops up when the unit is pressurized, providing an immediate visual readiness check without requiring a gauge.
• Corrosion Resistant Cap: Protects the fill opening from the moisture and corrosive environments common in petrochemical, offshore, and marine applications.
• Field Recharge: Cartridge-operated design allows on-site recharge by a certified technician without shop equipment.
• 12-Year Limited Warranty: Ansul's 12-year limited warranty from date of delivery.

The HF-I-K-30-G is specified wherever pressurized flammable liquid or gas fires are a credible hazard:

• Pressurized Fuel Lines and Systems: Refineries, pipelines, and process facilities where pressurized hydrocarbon streams can produce torch fires requiring high flow rates to overcome the fuel pressure.
• LPG and Compressed Gas Facilities: Propane and natural gas distribution operations where pressurized gas fires demand agent delivery rates that exceed standard extinguisher capability.
• Aviation Fueling and Ground Support: Aircraft fueling operations where pressurized fuel system fires and spill fires both require immediate high-volume Purple K response.
• Offshore Platforms: Pressurized process piping and wellhead areas where the combination of Purple K and high flow rate is the appropriate first-response tool.
• Hydraulic System Fires: Heavy industrial equipment with high-pressure hydraulic systems where oil injection fires demand high-flow agent delivery.

To maintain NFPA 10 compliance, the HF-I-K-30-G must follow a documented maintenance schedule:

• Monthly Visual Inspection: Verify the nitrogen cartridge safety seal is intact, the pull pin and tamper seal are in place, and the indicator fill cap shows no pressurization at rest. Confirm the corrosion resistant cap is intact and the hose and high-flow nozzle are free of damage or obstruction.
• Annual Maintenance: A certified technician must inspect all components, verify nitrogen cartridge condition, check the high-flow nozzle assembly for wear or blockage, and confirm Purple K agent has not packed. Document on the inspection tag.
• 6-Year Internal Examination: Full internal inspection per NFPA 10 including agent removal, cylinder interior inspection, and component replacement as needed.
• 12-Year Hydrostatic Test: The carbon steel agent tank must undergo hydrostatic pressure testing per NFPA 10 and DOT requirements.

What is the difference between this and the standard Red Line Purple K 30 lb (RL-PK-30-G)?

The HF-I-K-30-G delivers agent at 0.99 lbs/sec through a high-flow nozzle and reaches 30 feet. The standard RL-PK-30-G uses a standard flow nozzle with a lower flow rate and shorter range. The high-flow model is specifically intended for pressurized liquid and gas fires per NFPA 10 — it is not simply a "better" version of the standard model, but a different tool for a different hazard type. Both carry a 120-B:C rating, but the high-flow design achieves that rating through mass flow rate rather than per-pound agent efficiency alone.

Why does the HF model weigh significantly more than a standard 30 lb unit?

The charged weight of 51.5 lbs reflects both the 30 lb agent charge and a larger nitrogen cartridge required to achieve the high flow pressure delivery. The larger propellant charge drives the higher mass flow rate.

Is this unit appropriate for standard pool or spill fires?

Yes. Per NFPA 10, high flow extinguishers can also extinguish standard fire types. The HF-I-K-30-G is effective on all Class B and C fires — it is simply optimized for the more demanding pressurized liquid and gas fire scenarios. If your facility's primary hazard is standard pool fires rather than pressurized fires, the standard RL-PK-30-G is also appropriate and less expensive.
