Wholesale PricingThe Ansul Sentry AA05S-1VB is a professional-grade, 5 lb multipurpose ABC dry chemical fire extinguisher engineered specifically for mobile work environments and light hazard industrial zones. With a 3-A:40-B:C rating, this unit delivers triple the Class A knockdown power of a standard entry-level extinguisher while remaining compact enough for service vehicle mounting.
Charged with Ansul's FORAY monoammonium phosphate (MAP) agent, the AA05S-1VB is constructed with a seamless steel cylinder and high-tensile strength components built to endure the high-vibration life of a service vehicle. Every unit comes standard with a heavy-duty vehicle bracket, ensuring the extinguisher remains secure during transit. Whether you are outfitting a regional service fleet or upgrading a workshop, the AA05S-1VB delivers the durability necessary for commercial fleet protection.
The Science of Suppression: MAP Agent Performance
The 3-A Thermal Benchmark
A 3-A rating indicates that the 5 lbs of monoammonium phosphate in this unit provides the equivalent extinguishing power of 3.75 gallons of water on Class A combustibles. This allows an operator to suppress a significant fire involving wood or textiles without the weight and potential damage of a water unit.
FORAY Agent on Class A Fires
On solid fuel fires, the MAP agent undergoes a sintering reaction when it contacts the hot fuel surface, melting to form an oxygen-excluding crust. This seals the fuel surface and prevents the deep-seated re-flash that often occurs with lower-quality agents, effectively starving the fire of its fuel-air interface.
Vapor Suppression on Class B Fires
For flammable liquid fires involving gasoline, oils, and solvents, the AA05S-1VB is rated to suppress up to 40 Class B rating units of a fuel fire. The agent interrupts the free-radical chain reaction of the flame and creates a smothering barrier that prevents fuel vapors from reaching oxygen.
Why the AA05S-1VB is the Fleet Manager's Choice
- Seamless Steel Integrity: The AA05S-1VB uses a seamless cylinder design, increasing structural integrity for extinguishers subjected to constant vibration, road shock, and temperature cycling.
- USCG and DOT Compliance: When mounted with the included bracket, this unit meets USCG marine fire standards and DOT commercial vehicle requirements, keeping your fleet compliant during roadside inspections.
- Fully Rechargeable: The Sentry AA05S-1VB can be serviced and returned to duty for decades rather than being discarded after a single use, lowering total cost of ownership.
- Service Trucks and Delivery Vans: The standard choice for protecting mobile assets where fuel and packaging coexist.
- Manufacturing Facilities: Safeguarding CNC machinery and industrial workbenches with a compact unit.
- Auto Repair Shops: Providing the necessary Class B knockdown for bays alongside high-voltage diagnostic tools.
- Office Buildings: The ideal size for breakrooms and mechanical closets where paper and electrical hazards are concentrated.
- Construction Equipment: Mounted in the cabs of excavators and forklifts to provide immediate operator protection.

To maintain NFPA 10 compliance and ensure your fleet remains inspection-ready, the AA05S-1VB must follow a standard maintenance protocol:
- Monthly Visual Inspection: Verify the pressure gauge is in the green zone and the unit is securely seated in its vehicle bracket.
- Annual Professional Service: A certified technician must conduct an external examination and verify the chemical's fluidity to prevent dry chemical packing from road vibration.
- 6-Year Internal Maintenance: Every six years, the agent must be recovered and internal components inspected per NFPA 10 requirements for commercial vehicle safety equipment.
- 12-Year Hydrostatic Test: Mandatory to verify the structural integrity of the steel pressure vessel.
Is this unit better than a 2.5 lb extinguisher for my truck?
A 5 lb unit provides double the agent volume and significantly more suppression duration. Most fleet safety managers prefer 5 lb units because they provide the margin of safety needed for real-world fuel fires in mobile applications.
Can I use this on a grease fire?
While this unit is Class B rated, the high-velocity dry chemical discharge can splash burning grease and potentially spread the fire. For food trucks and commercial cooking lines, a Class K fire extinguisher is required for primary cooking line protection per NFPA 10.
Why choose Ansul Sentry over a retail brand?
Most retail-grade units use plastic valves. Ansul Sentry extinguishers use extruded aluminum valves and seamless steel cylinders, designed for industrial longevity in environments where reliability cannot be compromised.
