30LB Ansul Redline Cartridge (Foray Dry Chemical)

The Ansul Red Line RL-A-30-G is a 30 lb cartridge-operated hand-portable fire extinguisher charged with FORAY (monoammonium phosphate) ABC dry chemical — the standard-flow ABC variant of the Red Line 30 lb family. Rated 10-A:80-B:C, it provides full Class A, B, and C coverage from a single unit built to the Red Line's rugged industrial standard. This is the straightforward specification for mixed-hazard environments where ordinary combustibles, flammable liquids, and electrical equipment all coexist, and where the application does not require the high-flow nozzle of the HF model or the corrosion-resistant finish of the CR model.

As part of the Red Line cartridge-operated family, the RL-A-30-G stores the nitrogen propellant and the agent separately. The agent tank remains at atmospheric pressure until activation, which eliminates the slow pressure loss that affects stored-pressure units over years of industrial standby. The carbon steel cylinder is finished with Ansul's polyester powder coat for durability against impact, vibration, and corrosion. Every moving part is accessible for annual service, and the unit can be field-recharged on-site without shop pressurization equipment. It carries a 12-year limited warranty and is approved by UL, ULC, FM, and USCG.

FORAY ABC Agent: Triple-Class Coverage

FORAY is monoammonium phosphate (MAP) dry chemical — Ansul's multipurpose ABC agent. It is the only dry chemical agent in the Red Line family that suppresses all three standard fire classes:

• Class A (Ordinary Combustibles): MAP undergoes sintering at approximately 350°F, melting to form an oxygen-excluding crust over wood, paper, and textile fires. This prevents deep-seated re-ignition after initial knockdown.
• Class B (Flammable Liquids): The fluidized chemical cloud interrupts the free-radical chain reaction in the flame zone, providing rapid knockdown on gasoline, oil, solvent, and fuel fires.
• Class C (Electrical Equipment): The non-conductive agent allows safe suppression of energized electrical panels, motors, and wiring without risk of electrical shock to the operator.

Red Line Platform Features

• Carbon Steel Cylinder: Tough carbon steel shell with polyester powder coat finish resists impact, vibration, and corrosion through years of industrial service.
• Cartridge-Operated Reliability: Separated propellant design ensures the agent remains at atmospheric pressure until needed, eliminating slow-leak pressure loss and making every moving part accessible for maintenance inspection.
• Field Recharge: Can be recharged on-site by a certified technician using Ansul-approved modified technical FORAY agent (pail part no. 434906). No shop pressurization equipment required.
• Metal Cartridge Guard Option: A field-installable metal cartridge guard is available as a distributor option, protecting the nitrogen cartridge from physical damage in tough environments.
• 12-Year Limited Warranty: Ansul's 12-year limited warranty from date of delivery to the original end-user purchaser.

The RL-A-30-G is the right specification for high-hazard environments where mixed fire classes are present and the standard flow rate is appropriate for the hazard:

• Heavy Manufacturing Facilities: Production areas where ordinary combustibles, flammable lubricants and cutting fluids, and energized machinery all coexist — requiring ABC coverage at industrial capacity.
• Paint Spray Booths and Coating Operations: Flammable solvent vapors (Class B), accumulated overspray on combustible surfaces (Class A), and electrical ignition sources (Class C) create a mixed-hazard environment that FORAY addresses in a single unit.
• Mining Operations: The Red Line's rugged construction and field recharge capability make it a practical choice for remote mining sites. The ABC agent covers the mixed hazards of equipment fuel, electrical systems, and combustible materials common in mining environments.
• Oil Pumping Stations and Production Lines: Fuel storage and process areas with surrounding ordinary combustibles where ABC coverage is required rather than BC only.
• Heavy Construction Sites: Equipment fuel areas, generator rooms, and material storage zones where mixed fire class exposure warrants an ABC unit at industrial scale.
• Fleet and Vehicle Mounting: USCG approved with the proper bracket for marine vessels, and suitable for large vehicle mounting where 30 lb ABC capacity is specified.

To maintain NFPA 10 compliance, the RL-A-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 unit is in its designated location. Confirm inspection tags are current and the hose and nozzle are free of obstruction.
• Annual Maintenance: A certified technician must inspect all components — every moving part on the Red Line is designed to be accessible for this purpose. Verify nitrogen cartridge condition, check hose assembly, and confirm FORAY 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. Recharge only with Ansul-approved modified technical FORAY agent (pail part no. 434906).
• 12-Year Hydrostatic Test: The carbon steel agent tank must undergo hydrostatic pressure testing per NFPA 10 and DOT requirements to verify structural integrity.

What is the difference between this and the High Flow FORAY model (HF-I-A-30-G-1)?

The RL-A-30-G uses a standard flow nozzle and is rated 10-A:80-B:C. The HF-I-A-30-G-1 uses a high-flow nozzle delivering agent at a higher mass flow rate and is rated 40-A:120-B:C, but weighs significantly more at 54.5 lb charged versus 53 lb for the standard model. Per NFPA 10, high-flow extinguishers are specifically designed for pressurized flammable liquid and pressurized gas fires. If your hazard is standard pool or spill fires and ordinary combustibles without a pressurized fuel component, the RL-A-30-G is the appropriate specification. If pressurized fuel or gas fires are credible, specify the high-flow model.

Why choose FORAY over Purple K for a 30 lb Red Line unit?

Purple K (potassium bicarbonate) is approximately twice as effective per pound as FORAY on Class B flammable liquid fires, but it is a BC-only agent with no Class A rating. If your environment has significant ordinary combustible exposure alongside flammable liquid and electrical hazards, FORAY's ABC coverage eliminates the need to stage multiple agent types. If your hazard is purely Class B and C, Purple K delivers more suppression efficiency per pound on those fire classes.

Can this unit be recharged with standard FORAY agent?

No. All Red Line Class A extinguishers must be recharged with Ansul's modified technical FORAY dry chemical (pail part no. 434906), which is specifically formulated for the Red Line platform's operating characteristics. Do not substitute standard Sentry-grade FORAY agent — it will not maintain the unit's listed performance and may affect reliability.
