Overview
The Amerex B500 is a 5 lb ABC dry chemical fire extinguisher rated for Class A, B and C fires, covering ordinary combustibles, flammable liquid spills and live electrical equipment. It discharges in about 14 seconds through an all-metal aluminum valve.
Amerex is a commercial fire equipment maker, and the B500 carries that lineage into a home-sized unit: an all-metal valve assembly rather than a plastic head, sized at 5 lbs for a garage, workshop or larger kitchen than a typical 2.5 lb residential can covers. A wall bracket is included for mounting.
- 5 lb ABC dry chemical agent
- Rated for Class A, B and C fires
- About 14 second discharge time
- All-metal aluminum valve, wall bracket included
Who it's for
Suited to a garage, workshop or anyone who wants a bit more capacity than the smallest residential extinguishers offer, with metal-valve construction built to hold up. Not the pick for someone who wants the lightest, smallest possible unit for a single cabinet.
Pros and cons
- All-metal aluminum valve construction
- 5 lb capacity covers more than a small residential can
- Covers Class A, B and C fires in one unit
- Wall bracket included
- Heavier and bulkier than a compact 2.5 lb kitchen unit
- No mention of a rechargeable option in the listing
Performance notes
The ABC dry chemical agent covers ordinary combustibles, flammable liquid spills and live electrical equipment in one unit, discharging over about 14 seconds through an all-metal aluminum valve rather than a plastic one. The 5 lb capacity gives more working time and coverage than the smaller 2.5 lb residential cans.
