Badger | 5lb Advantage ABC Fire Extinguisher | 21007866

The Badger Advantage ADV-550 is a rechargeable, 5 lb ABC dry chemical fire extinguisher built for light industrial, commercial, and residential applications where more suppression power is needed than a 2.5 lb unit provides. Rated 3-A:40-B:C, it offers a meaningful step up in Class A, B, and C capability while still keeping a manageable, lightweight profile for quick deployment.

The Advantage line is built around a larger neck opening and square thread valve design that allows the valve to be removed and reinstalled quickly during service, cutting downtime and long-term maintenance cost compared to standard valve designs. The unit uses a corrosion-resistant aluminum cylinder with a heavy-duty threaded metal siphon tube, and ships with a wall hanger for fixed mounting. It is fully rechargeable and backed by a 6-year manufacturer warranty.

Why the Advantage 5 lb Steps Up From the 2.5 lb Model

The jump from 1-A:10-B:C to 3-A:40-B:C represents a significant increase in both Class A coverage of ordinary combustibles and Class B suppression capacity for flammable liquid fires, while the unit remains light enough for most users to deploy without difficulty. This makes the ADV-550 the workhorse size for facilities and vehicles where code requirements call for more than the smallest unit but a 10 lb or larger model would be excessive.

The Advantage Service Design

• Square Thread Valve: The larger neck opening and square thread design speed up valve removal and reinstallation during required service, leading to shorter technician visits and lower long-term service costs.
• Corrosion-Resistant Aluminum: The painted aluminum cylinder and heavy-duty metal siphon tube resist corrosion and stand up to the vibration of vehicle or marine mounting.
• Nitrogen Propellant: A stored-pressure design using nitrogen as the expellant gas, factory charged to 195 PSI operating pressure.

The ADV-550's 3-A:40-B:C rating makes it suited for moderate hazard environments stepping up from light-duty protection:

• Light Industrial Facilities: Workshops and small manufacturing spaces where ordinary combustibles and occasional flammable liquid hazards coexist.
• Commercial Buildings: Offices, retail spaces, and similar occupancies where code requires more capacity than a 2.5 lb unit provides.
• Fleet Vehicles and Heavy Equipment: Suitable for trucks and equipment where DOT and USCG approval (with the proper bracket) are required.
• Residential Garages and Workshops: A practical step up for homeowners who want more capacity than an entry-level unit offers.

To maintain NFPA 10 compliance, the ADV-550 must follow a standardized maintenance cycle:

• Monthly Visual Inspection: Verify the pressure gauge is in the green zone and the safety pin and tamper seal are intact. Confirm inspection tags are current.
• Annual Professional Service: A certified technician must conduct an examination and verify the chemical's fluidity. The square thread valve speeds up this process during scheduled service.
• 6-Year Internal Maintenance: Every six years, the agent must be recovered and internal components inspected per NFPA 10.
• 12-Year Hydrostatic Test: Mandatory to verify the structural integrity of the aluminum cylinder.

How does the 5 lb compare to the 2.5 lb Advantage model?

The 5 lb ADV-550 carries a 3-A:40-B:C rating compared to 1-A:10-B:C for the 2.5 lb unit, meaning significantly more Class A and Class B suppression capacity. Choose the 5 lb model when code requirements or hazard assessment call for more capacity than the compact 2.5 lb size provides.

Is this unit rechargeable?

Yes. The ADV-550 is a fully rechargeable, stored-pressure unit. After any discharge, it can be professionally recharged and returned to service by a certified fire equipment technician.

Does it come with a mounting bracket?

This unit ships with a standard wall hanger. A separate vehicle bracket is available for mobile and marine mounting applications where USCG approval requires a proper bracket.
