20LB Ansul Redline Cartridge (Foray Dry Chemial)

The Ansul Red Line RL-A-20-G is a 20 lb cartridge-operated hand-portable fire extinguisher charged with FORAY (monoammonium phosphate) ABC dry chemical — the standard-flow ABC variant of the Red Line 20 lb family. Rated 40-B:C with full Class A and C coverage, it is built for mixed-hazard industrial environments where ordinary combustibles, flammable liquids, and electrical equipment all coexist, and where the reliability, durability, and field serviceability of the Red Line platform are required.

FORAY is the only dry chemical agent in the Red Line family that provides Class A, B, and C coverage from a single unit. This makes the RL-A-20-G the generalist workhorse of the 20 lb Red Line line — the correct specification when your hazard assessment requires ABC coverage and the application does not require the high-flow nozzle of the HF model or the corrosion-resistant finish of the CR model. The agent tank remains at atmospheric pressure until activation, the carbon steel cylinder is finished with Ansul's polyester powder coat, and the unit can be recharged on-site without shop 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 and the only dry chemical in the Red Line portfolio rated for 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 the deep-seated re-ignition that occurs when only the surface of porous fuel is treated.
• 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. Meets or exceeds ANSI/UL 299 and 711 or ULC S504 and S508.
• 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 harsh environments.
• 12-Year Limited Warranty: Ansul's 12-year limited warranty from date of delivery to the original end-user purchaser.

The RL-A-20-G is the right specification for high-hazard environments where mixed fire classes are present and the 20 lb size is appropriate:

• Manufacturing and Assembly Facilities: Production areas where ordinary combustibles, flammable lubricants, and energized machinery all coexist — requiring ABC coverage at industrial capacity in a manageable size.
• Paint Spray Booths and Coating Operations: Flammable solvent vapors (Class B), overspray on combustible surfaces (Class A), and electrical ignition sources (Class C) create the mixed-hazard environment FORAY addresses in a single unit.
• Mining Operations: The Red Line's field recharge capability and broad temperature range make it practical for remote mining sites where a service shop visit is not feasible.
• Heavy Construction Sites: Equipment fuel areas and generator rooms where Class A, B, and C hazards all coexist at a scale that warrants 20 lb capacity.
• Fleet and Vehicle Mounting: USCG approved with the proper bracket for marine vessels. Also suitable for vehicle mounting where 20 lb ABC capacity is specified.

To maintain NFPA 10 compliance, the RL-A-20-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 the RL-A-20-G and the RL-A-30-G?

Both are standard-flow FORAY ABC Red Line units. The RL-A-30-G carries 30 lbs of agent and is rated 10-A:80-B:C with a 24.5-second discharge and 25-foot range. The RL-A-20-G carries 20 lbs and is rated 40-B:C with a 28-second discharge and 22-foot range. Specify the 30 lb model when greater agent volume and higher suppression ratings are required. The 20 lb model is appropriate when size and weight are limiting factors or when the 40-B:C rating satisfies the hazard assessment.

Why choose FORAY over Purple K for a 20 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 makes it the correct specification. If your hazard is purely Class B and C with no Class A exposure, the RL-PK-20-G delivers more B:C suppression efficiency per pound.

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), 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.
