DAIKIN ROUND FLOW CASSETTE
36 000 BTU of cooling from a panel in the ceiling
The Daikin FCAG100B 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 9.5 kW of cooling (about 32 400 Btu/h) and 10.8 kW of heating.
It comes as a complete system: the FCAG100B indoor unit, the Sky Air Active Series AZAS100MV (single-phase) or AZAS100MY (three-phase) outdoor unit, the white BYCQ140EW decoration panel and a Madoka wired controller, all running on R32.
This is the first size on the larger 246 mm indoor body, with half as much airflow again as the 24 000 BTU unit. It is also the first size you can order on a three-phase supply.
Enough air for a whole office floor, from one panel in the ceiling.
WHERE IT WORKS
Open-plan offices, showrooms and restaurants
The 36 000 BTU size is for spaces where a pair of wall units would otherwise be needed: an open-plan office, a showroom, a restaurant dining room or a large entertainment area in a home.
Each of the four flaps can be set separately, so the air can be kept off a till, a row of desks or a dining table while the rest of the room is cooled.
Daikin rates it at 9.5 kW, which suits around 60 to 90 m² as a rough guide. A large room is often better served by two smaller cassettes than by one big one, and we are happy to look at the layout with you.
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 36 000 BTU system pairs the cassette with the Sky Air Active Series outdoor unit: the AZAS100MV on a single-phase supply or the AZAS100MY on three-phase. Choose the power supply in the menu above; the cassette, panel and controller are the same either way.
Three-phase lets a business spread the load across its phases, and is usually what an electrician recommends where a three-phase supply is already in place. A home on single-phase power can run this size without an upgrade.
Daikin rates the pair at a seasonal efficiency of 5.67 (SEER, A+) in cooling and 3.85 (SCOP, A) in heating.
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 36 000 BTU cassette sits against the alternatives
The Daikin Sky Air FAA100B high-wall unit runs on the same Active Series outdoor unit at 9.5 kW. It is simpler to install, with no ceiling opening, but throws air from one wall.
The Daikin round flow cassette 24 000 BTU is the size down, on the slimmer 204 mm body. If the unit you are replacing was a true 36 000 Btu/h, the Daikin round flow cassette 42 000 BTU at 12.1 kW is the closer match.
For a large office, two 24 000 BTU cassettes spread over the floor often cool more evenly than one large unit, at the cost of a second outdoor unit.
Questions we are asked about the 36 000 BTU cassette
No, and it is worth knowing before you order. Daikin rates the FCAG100B system at 9.5 kW of cooling, about 32 400 Btu/h. The trade sells the 100 class as 36 000 BTU. If you are replacing a unit that really delivered 36 000 Btu/h (about 10.5 kW), the 42 000 BTU system at 12.1 kW is the like-for-like choice.
As a rough guide, around 60 to 90 m² with a standard ceiling: an open-plan office, a showroom or a restaurant dining room. A large or long room is often better served by two smaller cassettes, so send us the layout and how it is used 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.
