Stadler Form Lukas Pro 50L Dehumidifier: High-Capacity Dehumidification for Large Spaces up to 175 m²
When a standard household dehumidifier is not enough – a villa floor, a large open-plan apartment, a large office, a hotel suite or a storage room within its rated size – the Stadler Form Lukas Pro 50L Dehumidifier & Air Purifier is the high-capacity option in the Stadler Form UAE range. It is rated for up to 50 litres of moisture removal per day and for rooms up to 175 m² (435 m³), and it does this at household noise levels, with a night mode from 38 dB(A).
A note on the headline figure: 50 L/day is the maximum rated extraction, measured under specified temperature and humidity test conditions so that models can be compared. In a cool, air-conditioned UAE room the unit extracts less than that in a day – but still far more than a 20-litre-class machine in the same room. Treat it as a capacity class, not a promise that every customer will collect 50 litres every 24 hours.
This page is the definitive guide to the 50-litre class in the UAE. For a review of the whole device, see the complete Lukas Pro review; to compare it with the 20-litre Lukas and Albert, see Albert vs Lukas vs Lukas Pro.
Powerful 50L Dehumidification for Large Spaces
The defining feature of Lukas Pro is its 50-litre-per-day rated capacity – two and a half times the 20 L/day of Stadler Form’s Lukas and Albert. That headroom is what lets one unit hold humidity in a large space instead of running flat out and falling behind.
A 50-litre class suits:
- Large villas and villa ground floors
- Large and open-plan apartments and penthouses
- Hotel suites, spas and back-of-house laundry rooms
- Large and open-plan offices, boardrooms and training rooms
- Showrooms, retail spaces and restaurants
- Basements, gyms and pool houses
- Clinics and waiting rooms
- Storage rooms and archives within the unit’s rated room size
- Laundry and drying rooms
Lukas Pro is a high-capacity household and light-commercial dehumidifier, not an industrial construction dryer: for drying out buildings after water damage or on construction sites, a dedicated construction dryer is the right tool.
Covers Large Rooms up to 175 m² (435 m³)
Coverage is the specification to check before capacity. Lukas Pro is rated for rooms of up to 175 m² – 435 m³ of air – which is roughly a villa ground floor, a full-floor apartment or an office of twenty desks.
That rating makes it the right size for:
- Open-plan living, dining and kitchen areas
- Large offices and conference rooms
- Showrooms and hotel lobbies
- Large bedrooms and master suites
- Classrooms, libraries and lecture halls
- Villas with high ceilings
Remember that rooms connected by open doors behave as one volume. Instead of several small units, one Lukas Pro with its swing function distributing dry air can manage a connected area up to its rating. Very large properties still need one unit per floor or per closed zone – no single portable unit treats a whole building.
Large Water Tank with Continuous Drainage
Lukas Pro has a 5.2-litre water tank with automatic switch-off when it is full, so it can run for long stretches between emptying.
For continuous operation the included drainage hose (100 cm) takes the water straight to a floor drain or outlet and the tank never needs emptying.
Continuous drainage is what makes it practical for:
- 24/7 operation in villas and basements
- Holiday homes and properties left empty over the summer
- Hotel back-of-house and laundry rooms
- Offices and storage rooms that run unattended overnight
- High-humidity coastal locations
Set the digital hygrostat to your target (40–50 % is a good range for UAE interiors), connect the hose and the unit holds the level on its own. Our guide to protecting your UAE home from humidity while you travel covers the set-up.
Quiet Operation: 38–55 dB(A), Night Mode from 38 dB
High-capacity dehumidifiers are often assumed to be loud. Lukas Pro runs between 38 and 55 dB(A) depending on the fan level, and in night mode from 38 dB(A) – quieter than a normal conversation.
That makes it usable in occupied rooms, not only in plant rooms:
- Bedrooms and master suites
- Hotel rooms
- Offices and meeting rooms
- Clinics and waiting areas
- Living rooms
Compare the lowest setting when you look at noise figures: that is the level you will run at night. For the quietest 20-litre option in the range, Albert runs at 33–44 dB(A).
Built for Large Homes and Large Indoor Spaces
Sustained humidity above 60 % in a large space leads to:
- Higher likelihood of mould growth
- Condensation on windows and cold walls
- Damp walls and musty odours
- Swollen wood and damaged furniture
- Poor indoor comfort – air that feels heavy even when it is cold
Lukas Pro brings the humidity of a large room back into the recommended range (the US EPA suggests 30–50 %, and below 60 %) and holds it there with its hygrostat. Whether it is a family villa or a large office floor, the 50-litre class provides the headroom that year-round humidity control in a large space needs.
2-in-1 Dehumidifier and Air Purifier
Beyond moisture removal, Lukas Pro is a full air purifier. The included HEPA H11 filter delivers 327 CADR – enough to exchange the air in a 131 m² room once every hour – and in independent laboratory testing removed over 99.99 % of germs (tested with Staphylococcus albus).
The HEPA filter captures:
- Dust and sand
- Pollen and allergens
- Fine airborne particles (PM2.5 and PM10)
- Bacteria and other germs
A particle sensor shows air quality in real time (white, yellow, red), and dehumidification can be switched off to run purification alone on dusty but dry days. Replace the HEPA H11 filter roughly every 12 months depending on air quality. Two functions in one appliance is the concept we explain in why a 2-in-1 dehumidifier and air purifier makes sense for UAE homes.
Smart Wi-Fi Control
Lukas Pro connects to Wi-Fi and the Stadler Form app, so you can monitor humidity, adjust settings and set timers from your phone – useful when the unit runs in a villa you are away from or an office you manage remotely. The touch panel gives the same control on the device.
Controls and features:
- Digital hygrostat with target humidity
- Timer
- Four power levels
- Swing air distribution
- Laundry-drying mode
- Automatic shut-off when the tank is full
- Real-time air quality indicator
Set-up takes a few minutes – see our step-by-step app connection guide.
Fast Laundry Drying
Drying clothes indoors releases litres of water into the room. Lukas Pro’s dedicated laundry-drying mode targets that moisture and uses the swing function to move dry air across the washing, so clothes dry faster and the room does not turn into a condensation problem – useful in the UAE summer, when drying outdoors is not an option.

Frequently asked questions about the 50-litre Lukas Pro
It is the maximum rated extraction, measured under specified laboratory temperature and humidity conditions so that models can be compared. In a cool, air-conditioned UAE room Lukas Pro extracts less than 50 litres in a day, but still far more than a 20-litre-class unit in the same room, and it reaches the target humidity faster.
Yes. Lukas Pro is rated for rooms up to 175 m² (435 m³), which covers a typical villa ground floor or a large open-plan area. Very large villas may still need one unit per floor or per closed zone.
Up to 175 m² / 435 m³ for dehumidification. As an air purifier it exchanges the air in rooms of up to 131 m² once per hour, with a clean-air delivery rate of 327 CADR.
For a 50-litre-class unit, yes: 38–55 dB(A) depending on the fan level, and from 38 dB(A) in night mode, which is quieter than a normal conversation. If you need the quietest possible unit for a bedroom under 70 m², Albert runs at 33–44 dB(A).
No, not if you connect the included 100 cm drainage hose to a floor drain or outlet – it then runs continuously. Without the hose, the 5.2-litre tank switches the unit off automatically when full.
When the space is much larger than 70 m², when several rooms open into each other, when the humidity load is heavy (coastal, ground floor, basement, laundry), or when you want dehumidification and air purification in one unit. For a normal apartment or a single room, a 20 L Lukas or Albert is the more appropriate size.
Five years, as part of the Stadler Form Pro Series – supported by Stadler Form UAE’s own service centre in Dubai and a team of engineers who deliver, install and follow up when the HEPA filter is due.
If your requirement is a 50-litre dehumidifier for a large room, a villa, a large office or a space with a heavy humidity load in the UAE, Lukas Pro is the Stadler Form model built for it – with the capacity, the coverage, the HEPA purification and the five-year warranty to match.
