Ceiling cassette air conditioning

Cassette units recess into the false ceiling and sit flush with the tile line — draught-free, discreet, and invisible from the occupied space. The Daikin Fully Flat FFA range fits a standard 600×600 ceiling tile with 4-way discharge, individual damper control, and optional fresh-air intake.

Key benefits

01

Flush ceiling integration

Sits in a standard 600×600 tile — invisible until the fascia is spotted. No wall real estate lost.

02

Even 4-way airflow

Individual damper control per direction avoids the cold-draught complaints that plague single-blow units.

03

Whisper-quiet in occupancy

Fully Flat FFA runs as low as ~26 dB(A) — usable directly above meeting tables and hotel beds.

04

Sensor-driven energy saving

Optional presence and floor-temperature sensors modulate output to actual demand, not thermostat setpoint alone.

05

Optional fresh-air intake

Ducted fresh-air spigot lets one indoor unit contribute to Building Regs Part F ventilation compliance.

Daikin model families

  • 01
    FFA-A9 / RZAG-B

    Fully Flat Cassette — Mini Sky Air

    Commercial fit-outs with long pipe runs.

    Fully-flush cassette paired with Mini Sky Air outdoor for up to 50m pipe runs. Optional fresh-air intake, individual airflow control, energy-saving sensors — the specifier-grade choice for offices and hotels.

  • 02
    FFA-A9 / RXM-A

    Fully Flat Cassette — Standard inverter

    Compact commercial and light-commercial spaces.

    Same flush FFA cassette body paired with a standard split outdoor — the economical spec for small commercial fit-outs, cellular offices, and boutique-hotel single-room deployments. Flexible airflow and optional fresh-air intake carry over.

  • 03
    FCAG-B / AZAS

    Roundflow Cassette — Active

    Entry-level 360° roundflow cassette for value fit-outs.

    800×800 roundflow cassette with 360° discharge, paired with the AZAS outdoor. The value option when a Fully Flat FFA cassette isn't needed and the ceiling tile grid can accommodate an 800mm module. Individual damper control per direction avoids cold-draught complaints.

  • 04
    FCAG-B / RZASG

    Roundflow Cassette — Advance

    Standard commercial roundflow cassette paired with Sky Air Advance.

    800×800 roundflow cassette with the Sky Air Advance outdoor — the specifier default for offices, hotels and retail where 360° coverage matters more than tile-flush aesthetics. R-32, DIII-Net compatible, presence and floor-sensor options.

  • 05
    FCAG-B / RZAG

    Roundflow Cassette — Alpha

    Highest efficiency roundflow cassette for spec-driven projects.

    FCAG-B roundflow indoor paired with Sky Air Alpha for best-in-class SEER/SCOP. Right for BREEAM-scored fit-outs and long-hours occupied spaces where energy-in-use is scored on the tender.

  • 06
    FCAHG-B / RZAG

    Roundflow Cassette — Alpha (high-capacity FCAHG)

    Larger-capacity roundflow for high-ceiling or dense-load rooms.

    High-capacity FCAHG-B body — increased cooling and heating output for rooms with tall ceilings, dense occupancy, or high solar gain. Same 360° roundflow pattern and Alpha efficiency, sized up for hospitality atriums, showrooms and dense open-plan floors.

  • 07
    FCAG-B / RXM-A

    Roundflow Cassette — Standard inverter

    Economical roundflow spec for shorter pipe runs.

    FCAG-B roundflow cassette with a standard split outdoor — value option for small commercial and light-commercial fit-outs where the outdoor can sit within ~20m. R-32 refrigerant, individual damper control retained.

Frequently asked

Do I need a suspended ceiling to install a cassette AC?
Yes — cassette units recess into the ceiling void and sit flush with the tile grid, so you need at least a 250-350mm ceiling void depending on the model. If there's no false ceiling, specify ceiling-suspended (under-ceiling) units instead.
How many cassettes does an office need?
As a rough B2B rule of thumb, one Daikin FFA cassette covers about 30-40 m² of open-plan office at typical UK cooling loads (~120 W/m²). We size properly on a heat-load calculation — get a survey before ordering.
Can a cassette unit provide fresh-air ventilation as well?
Partially — the FFA range accepts a ducted fresh-air spigot that can supplement Building Regs Part F ventilation, but a dedicated MVHR unit is required for buildings that need heat-recovery ventilation on top of cooling.
