DAIKIN ROUND FLOW CASSETTE
48 000 BTU of cooling from a panel in the ceiling
The Daikin FCAG140B round flow cassette sits above the ceiling with only its 950 mm square panel showing, and sends air out through 360°. Daikin rates the system at 13.4 kW of cooling (about 45 700 Btu/h) and 15.5 kW of heating.
It comes as a complete system: the FCAG140B indoor unit, the Sky Air Active Series AZAS140MV (single-phase) or AZAS140MY (three-phase) outdoor unit, the white BYCQ140EW decoration panel and a Madoka wired controller, all running on R32.
It is the top of the FCAG range. Daikin rates it more efficient in both cooling and heating than the 42 000 BTU system, so where a room sits on the border between the two, the larger unit is the better buy to run.
The largest round flow cassette, and the most efficient of the three big sizes.
WHERE IT WORKS
The largest open spaces on one indoor unit
The 48 000 BTU size is for the largest rooms a single cassette can handle: a big showroom, a restaurant, a church or school hall, a gym floor or a large open-plan office.
Each of the four flaps can be set on its own from the controller, so air can be kept off a stage, a counter or a row of desks while the rest of the space is cooled.
Daikin rates it at 13.4 kW, which suits around 85 to 120 m² as a rough guide. Above that, two or more cassettes spread over the space are the better answer, and we will help work out the layout.
CONTROL
Every flap set from a wired controller
Each of the four flaps can be fixed separately from the wired controller, so air can be kept off a desk, a till or a dining table without moving the unit. Five fan speeds plus auto, draught prevention and ceiling soiling prevention come built in.
A Madoka BRC1H52W7 wired controller is included. It adds a weekly timer, set-point limits and home-leave operation, which holds an empty home, office or shop at a set temperature.
A black panel, an auto-cleaning filter panel and panels with presence and floor sensors can be ordered instead of the standard white panel. Ask us for a quote.
OUTDOOR UNIT
Single-phase or three-phase, your choice
The 48 000 BTU system pairs the cassette with the Sky Air Active Series outdoor unit: the AZAS140MV on a single-phase supply or the AZAS140MY on three-phase. Choose the power supply in the menu above; the cassette, panel and controller are the same either way.
At this size most premises run it on three-phase to spread the load. The single-phase version is there for buildings without a three-phase supply.
Daikin rates the pair at a seasonal efficiency of 6.00 (SEER) in cooling and 4.31 (SCOP) in heating, higher on both counts than the 42 000 BTU system.
INSTALLATION AND SERVICE
A built-in drain pump and a slim body
A drain pump is built in as standard and lifts condensate up to 675 mm, so the water can run to a drain well away from the unit.
The indoor unit is 246 mm tall and 840 mm square; below the ceiling, the panel is 950 mm square and 65 mm deep. Filters are reached from below by dropping the intake grille, and self-diagnosis points a technician to a fault.
A cassette has to be installed by a qualified installer who cuts the ceiling opening, hangs the unit from the slab and runs the piping, cabling and drain. Our installers cover the major South African cities and quote separately.
MADE FOR SOUTH AFRICAN POWER
Daikin South Africa stock
The system is supplied through Daikin South Africa for a 220–240 V single-phase supply or a 380–415 V three-phase supply, so the local Daikin warranty applies and parts come through Daikin’s South African network.
Auto-restart returns the system to its previous settings when the power comes back after load-shedding or an outage.
If you are unsure whether this is the right size, send us the room dimensions, ceiling height and how the space is used, and we will check it.

How the 48 000 BTU cassette sits against the alternatives
The Daikin round flow cassette 42 000 BTU is the size down at 12.1 kW, on the same body, panel and outdoor unit range.
Where there is no ceiling void, the largest Sky Air high-wall unit we list is the Daikin FAA100B at 9.5 kW, so a room this size on wall units needs two of them.
Beyond 13.4 kW, two or more cassettes are the answer: a pair of 36 000 BTU units, for example, gives 19 kW spread across the space.
Questions we are asked about the 48 000 BTU cassette
A little under the name. Daikin rates the FCAG140B system at 13.4 kW of cooling, about 45 700 Btu/h; a true 48 000 Btu/h would be about 14.1 kW. It is the largest round flow cassette, so a room that needs more is better served by two units.
As a rough guide, around 85 to 120 m² with a standard ceiling: a large showroom, a restaurant, a hall or a big open-plan office. Above that, two or more cassettes spread over the space do a better job, so send us the layout and we will advise.
The indoor unit is 246 mm tall and 840 mm square, so the ceiling void has to be deeper than 246 mm, with room for the hanger rods, piping and drain. Daikin’s installation manual gives the exact clearances, and the installer checks the ceiling on site. Below the ceiling, the panel is 950 mm square and 65 mm deep.
Use three-phase if the building already has it: the load is spread across the phases, and that is what most electricians recommend at this size. A home or small building on single-phase power can run the single-phase version without an upgrade. The cassette, panel and controller are the same either way.
Yes. The system includes the white BYCQ140EW decoration panel and a Madoka BRC1H52W7 wired controller. A black panel, an auto-cleaning filter panel and panels with presence and floor sensors can be ordered instead; ask us for a quote.
The Madoka controller on the wall handles everything day to day. For control away from home, Daikin offers an Onecta Wi-Fi adaptor for the round flow cassette as an extra. Ask us and we will quote the right adaptor for your system.
A drain pump is built in and lifts the water up to 675 mm, so the installer can run the drain to a suitable point rather than relying on a fall from the unit.
Yes. Auto-restart returns it to its previous settings when the power comes back.
No. A cassette has to be installed by a qualified installer, who cuts the ceiling opening, hangs the unit from the slab and runs the piping, cabling and drain. Our installers cover the major South African cities and quote separately.
