Ansul 443479 — CLEANGUARD+ model CA14-NM, a 14 lb FK-5-1-12 clean agent hand portable extinguisher built as an MR Conditional unit, rated 1-A:10-B:C.
FK-5-1-12 discharges as a liquid and flashes to a gas, is electrically non conductive and leaves no residue. What separates this model from the rest of the CLEANGUARD+ line is its construction: a stainless steel shell with an MR Conditional valve, hose and nozzle, tested to 7.0 tesla, which is what lets it be mounted inside the MRI room itself.
- UL/ULC rating 1-A:10-B:C; meets ANSI/UL 2129 and 711 and CAN/ULC S508 and S566
- Agent capacity 14 lb (6.35 kg); charged weight 19.16 lb (8.7 kg)
- Discharge 11.0 seconds at 1.45 lb/sec; range 10 ft (3 m)
- Temperature range -40 °F to 120 °F (-40 °C to 49 °C)
- 14.75 × 9.25 × 7.125 in. (375 × 235 × 181 mm) high, wide, deep
Ansul lists hanger hook 432964 as the standard mounting part here, where the rest of the line takes wall brackets. The other CLEANGUARD+ units are CA03VB, CA07, CA13 and CA25, none of them MR Conditional. Do not confuse the line with the older CLEANGUARD extinguishers, charged with HFC-236fa.
