ACD · SMD ducted unit · 4 sizes
The ACD SMD ducted unit hides in a drop ceiling or a bulkhead and pushes air through ducts. Its four sizes share one height, 201 mm, and one depth, 615 mm; only the width changes. Enter the size of your space: the “My space” tool tells you which cabinets fit.

Enter the free height, width and depth. For each size, “My space” gives the margin or what is missing, then the external static pressure printed on the sheet.
Your space (mm)
Cabinets, weights and airflow: ACD multi-zone sheet (MPD-22). External static pressure: both multi-zone sheets print two values per size, for example 0.25 / 0.4 in. w.c. for the 9,000 (as printed; the sheet does not say which is nominal and which is maximum). The tool only compares the cabinet with your space; at the on-site assessment we also check the hangers, service access, the drain and the duct route.
| Size | Width | Static pressure | Net weight |
|---|---|---|---|
| 9,000 | 701 mm | 0.25 / 0.4 in. w.c. | 22 kg |
| 12,000 | 701 mm | 0.3 / 0.4 in. w.c. | 23 kg |

Per the ACD multi-zone sheet, the SMD 24,000 ducted unit and the FCD 24,000 floor-ceiling unit give the same heat, 27,400 BTU/h, and connect to the same MPD outdoor unit. The first hides above the ceiling; the second stays in sight.
Ducted · SMD24KCHVS-I
Floor-ceiling · FCD24KCHVS-I
Per the ACD multi-zone sheet, the 24,000 ducted unit is only 201 mm tall, but it needs 1,100 × 615 mm above the ceiling, plus its ducts. The 24,000 floor-ceiling unit is fixed below the ceiling or set on the floor: 1,219 mm wide, 226 mm thick and 45 kg, against 31 kg for the ducted unit. Its sheet gives it more airflow (412 to 736 cfm vs. 324 to 588) and a higher published sound (44 / 48 vs. 34 / 42 dB(A)).
Good to know (AirGreen). The ducted unit pushes air through ducts to the chosen grilles, and the sound in the room also depends on those ducts; the floor-ceiling unit blows straight into the room it sits in. A ducted unit stays a single zone, with one temperature setting for all its grilles.

0.25 → 0.35
ACD’s sheets print 0.25 / 0.4 in. w.c. for the 9,000 ducted unit, 0.3 / 0.4 for the 12,000, 0.32 / 0.4 for the 18,000 and 0.35 / 0.4 for the 24,000: the first value rises, the second stays at 0.4.
ACD multi-zone sheets (MPD-22 and English edition)850 mm
The SMD ducted unit manual publishes a drain lift under 850 mm (33 ½ in.). The multi-zone sheet mentions no built-in pump: the drain route is checked on site.

Net weights of the ACD ducted unit: 22 kg at 9,000, 23 kg at 12,000, 27 kg at 18,000 and 31 kg at 24,000, to hang above the ceiling.

The ACD ducted cabinet is 201 mm tall and 615 mm deep, for all four sizes. The width changes: 701 mm at 9,000 and 12,000, 899 mm at 18,000 and 1,100 mm at 24,000. Hangers, service access and the drain come on top of the cabinet and are checked on site.
ACD multi-zone sheet (MPD-22), p. 3ACD’s sheets print two external static pressure values per size, from 0.25 / 0.4 in. w.c. on the 9,000 to 0.35 / 0.4 on the 24,000, without saying which is nominal and which is maximum. The duct route and length are confirmed at the on-site assessment.
ACD multi-zone sheetsPer the ACD sheet, the ducted unit moves 147 to 265 cfm at 9,000, 176 to 324 cfm for the 12,000, 294 to 412 cfm for the 18,000 and 324 to 588 cfm for the 24,000.
ACD multi-zone sheet (MPD-22), p. 3The 701 mm cabinets (9,000 and 12,000) fit on all five MPD outdoor units, the MPD 18,000 included. The 899 mm cabinet (18,000) needs at least an MPD 24,000, and the 1,100 mm cabinet (24,000) an MPD 36,000 or 42,000; the Multi-zone page compares the five outdoor units.
Combinations printed in both ACD multi-zone sheets; cabinets: MPD-22 sheet, p. 3The ACD sheet gives the ducted unit 31 to 37 dB(A) at 9,000, 32 to 39 at 12,000, 33 to 41 at 18,000 and 34 to 42 at 24,000, from the lowest setting to the highest.
ACD multi-zone sheet (MPD-22), p. 3Pricing for a 9,000 to 24,000 BTU SMD ducted unit is by quotation, installation included, with the MPD outdoor unit that runs it; the ducts are priced at the on-site assessment. That in-home estimate is free, with no obligation.
