Daikin Perfera FVXM50B 5.0kW Floor Standing Indoor Unit
The Daikin FVXM50B is a 5.0kW floor standing indoor unit from the Perfera range, designed to sit discreetly at skirting height rather than on a wall or ceiling — a popular choice where wall space is limited or a low-level heat source is preferred, such as under a window. Finished in white with a slim profile, it pairs with a compatible Daikin mono-split outdoor condensing unit (such as RXM50A9, sold separately) to form a complete reverse-cycle heating and cooling system.
Supplied as the indoor unit only, for connection to a compatible Daikin outdoor unit by an F-Gas certified installation company.
Key Features
- 5.0kW nominal indoor unit, floor standing format
- Slim profile: only 238mm deep
- R-32 refrigerant
- Sound pressure from 27 dBA on silent mode (cooling)
- 4-speed fan operation (High / Medium / Low / Silent)
- Suitable for pairing with compatible Daikin mono-split outdoor units
Benefits
- Discreet, low-level installation — ideal where wall or ceiling space is unavailable, or where a traditional radiator-height unit is preferred aesthetically.
- Quiet operation — indoor sound pressure from 27 dBA on the lowest fan speed makes it suitable for bedrooms and living spaces.
- Even heat distribution — floor-level discharge helps distribute warm air more evenly through a room in heating mode.
- R-32 refrigerant — lower environmental impact than older refrigerants.
Suitable Applications
- Living rooms and bedrooms where wall-mounted units are impractical
- Rooms with large glazed areas or limited wall space
- Replacement for traditional radiator positions
- Conservatories and garden rooms

Room Size Guide
As a general guide, the 5.0kW FVXM50B is suitable for rooms of approximately 25–35 m², subject to insulation standard, glazing, ceiling height, solar gain and occupancy. For commercial applications or rooms with unusual characteristics, a qualified engineer should carry out a full heat load calculation in accordance with CIBSE guidance.

Recommended Installation Accessories
To complete the installation, your engineer will typically require the following — all available from Airconspares:
- Pair coil — pre-insulated refrigerant pipework in the correct diameter for this unit (1/4" liquid / 1/2" gas)
- Wall brackets or ground mounting feet — for the paired outdoor unit
- Anti-vibration mounts — to reduce structure-borne noise from the outdoor unit
- Condensate pump — required where gravity drainage from the indoor unit is not available (Aspen Mini Orange or equivalent)
- Condensate drain hose — flexible hose for indoor unit drainage
- Local isolator switch — required by Part P of the Building Regulations
- Interconnecting cable — sized to the installation manual, to connect indoor and outdoor units
Pipework Installation Bundles
This unit requires a 1/4" liquid line; the gas line for this model is 1/2" (larger than our standard 3/8" bundle), so please confirm gas-side pipework separately with our team. Our pre-matched liquid-line bundle contains Lawton ACR copper coil, Armaflex EVO insulation, forged brass flare nuts and a Mastercool flaring tool:
- AC Copper Pipe Installation Bundle — 1/4" — liquid line (6.35mm) | available in 6m, 15m & 30m
Frequently Asked Questions
Does this listing include an outdoor unit?
No. This listing is for the FVXM50B indoor unit only. A compatible Daikin mono-split outdoor unit (such as RXM50A9) is sold separately.
Does this system include installation?
No. This listing is for the equipment only. Installation must be carried out by an appropriately F-Gas certified installation company.
What refrigerant does this system use?
R32. This is a lower global warming potential refrigerant compared to R410A. Handling requires F-Gas certification.
Can this unit heat as well as cool?
Yes, when paired with a compatible Daikin heat pump outdoor unit, the FVXM50B provides both cooling and heating.
What size room is this suitable for?
As a general guide, 25–35 m². However, room sizing depends on multiple factors. A heat load calculation is recommended for accurate sizing.
What pipe sizes does this unit require?
1/4" (6.4 mm) liquid line and 1/2" (12.7 mm) gas line.
How quiet is this unit?
From 27 dBA in cooling mode on the silent fan setting, rising to 44 dBA on high fan speed.
Is a local isolator required?
Yes. A local isolator switch is required by Part P of the Building Regulations and should be installed by a qualified electrician.
Which outdoor units is this compatible with?
Please contact us to confirm the correct matching outdoor unit for your installation — typically a Daikin RXM50 series mono-split outdoor unit.
Professional Installation Required
This air conditioning indoor unit must be installed and commissioned as part of a complete system by an appropriately F-Gas certified installation company. Installation, pipework, electrical connection and commissioning are not included in this listing unless separately agreed in writing. Handling of R32 refrigerant requires appropriate F-Gas certification under UK F-Gas Regulations.
