Ansul 440945 — SENTRY High-Flow stored-pressure hand portable fire extinguisher, model HF-AA10S, charged with 10 lb of ABC dry chemical.
High-flow units exist for one reason: NFPA 10 Section 5.5.4 treats pressurized flammable liquid and gas fires as three-dimensional or gravity-fed, and calls for at least 10 lb of agent discharged at 1 lb per second or faster. This one meets both, at 240 psi.

- Charged weight 17 lb; 20 1/2 × 8 1/4 × 5 1/4 in.

- Coast Guard Type A Size II and Type B, C Size II, with the proper bracket
Two numbers here are not interchangeable: 440945 is the part number in domestic packaging and HF-AA10S is the model, with 441337 the export pack. The neighbours differ by agent and size. HF-PK10S (440935) is the same shell charged with Purple-K and carries no Class A rating at all; HF-AA20-1 (440940) is the 20 lb ABC unit at 4-A:60-B:C. Vehicle bracket 435793 is ordered separately.
