The Fiamma Turbo Vent 40 is a 12V motorised rooflight ventilation system designed for motorhomes, caravans and van conversions. This 40 x 40cm unit fits standard roof openings of 39-40cm and works with roof thicknesses from 30mm to 45mm as standard, extending to 85mm with an optional kit. The Crystal cover allows natural light into your vehicle whilst the 10-blade variable speed fan exchanges air at rates up to 35 cubic metres per minute. Its electronic circuit enables quick direction changes between intake and extraction modes using the integrated control panel.
How does the Fiamma Turbo Vent control interior temperature?
The Turbo Vent uses the Polar Control thermostat system to automatically regulate interior temperature. When activated, it displays the current room temperature and runs the fan at your selected speed until the target temperature is reached. The 12V motor draws between 0.3-3 amps depending on speed setting, using 50% less electricity than comparable systems through efficient electronic circuitry. The five-speed settings include three intake levels and two extraction levels, operating silently on lower speeds for comfortable nighttime use.
Built from shock and UV-resistant materials, this vent includes double external aluminium mosquito screens preventing debris entry whilst providing permanent passive ventilation even when closed. The aerodynamic design reduces wind noise and vibration during travel. The cover opens and closes manually via a central arm that provides stability against high winds. Installation requires a 39cm square roof opening with the unit secured using 20 self-tapping screws and recommended sealants like Sikalastomer-710 or Dekalin. The system connects directly to your 12V battery supply and requires a 5-amp inline fuse for circuit protection.
Installation with sandwich technology with screws tightened from inside the vehicle, but it can also be secured from outside. Can be installed on roofs with depths of 3cm to 8.5cm using an optional extension kit, suitable for installation to roof openings of 39 cm to 40 cm squared .
This is more suited to a caravan than a motorhome due to its permanent ventilation.
The Crystal style Turbo-vent means that the glazing panel is transparent but has a slight "Graphite" tint on it.

Frequently Asked Questions
The Fiamma Turbo Vent 40 requires a square roof opening of 39cm to 40cm. The external frame dimensions are 460mm x 460mm, whilst the internal cut-out needs to be 390mm x 390mm up to 400mm x 400mm. This makes it a direct replacement for most standard 40x40cm roof vents from various manufacturers, eliminating the need to enlarge existing openings when upgrading from passive vents to motorised ventilation.
The Turbo Vent 40 fits roof thicknesses between 30mm and 45mm as standard. For thicker roofs between 50mm and 85mm, you'll need the optional Fiamma Extension Handle Kit, which extends the mounting to accommodate greater roof depths. This flexibility makes the vent suitable for panel vans, coachbuilt motorhomes and caravans with varying roof construction methods. Always measure your roof thickness before purchasing to determine whether the extension kit is required.
The Polar Control thermostat automatically activates the fan based on interior temperature differences you set via the control dial. When enabled, the system displays the current room temperature and runs the fan at your pre-selected speed until reaching the target temperature. The thermostat operates in both intake and extraction modes, automatically determining the optimal direction. This automation reduces power consumption by up to 50% compared to manually operated systems, as the fan only runs when temperature adjustment is needed rather than continuously. To maximise energy efficiency, set the Polar Control to minimum temperature difference once a comfortable temperature is achieved.
The White cover blocks out sunlight completely, preventing light transmission into your vehicle. The Crystal cover allows natural light to pass through whilst maintaining privacy, as it's translucent rather than transparent. Both versions feature identical ventilation performance with the same 10-blade fan, Polar Control thermostat and 35 cubic metres per minute airflow capacity. The choice between Crystal and White depends on whether you prefer additional natural lighting or complete light blocking in your sleeping or living area.
Yes, the Turbo Vent 40 is designed as a direct replacement for standard 40x40cm roof vents from various manufacturers. The unit fits existing 39-40cm roof openings without requiring modifications to the aperture size. Installation involves removing your old vent, connecting the 12V electrical supply with a 5-amp inline fuse, sealing the frame with appropriate sealant and securing with the supplied fixings. The reinforced frame accommodates vents from 36x36cm to 42x42cm, making it interchangeable with older Fiamma models and many other brands' 40cm vents.
Yes, the Turbo Vent offers permanent passive ventilation even when the cover is fully closed. The design allows continuous airflow through the double external mosquito screens, preventing condensation build-up and maintaining air circulation without running the motorised fan. This passive ventilation is particularly beneficial for bathroom installations where constant fresh air exchange is desirable. When the cover is open, the aerodynamic shape allows the vent to remain functional whilst travelling, though you should avoid using it in strong winds or heavy rain.
The Turbo Vent requires a direct connection to your 12V DC battery supply. You must install a 5-amp inline fuse in the circuit as specified in the fitting instructions - failure to fit this fuse or using an incorrect rating will invalidate your warranty. The unit draws between 0.3 and 3 amps depending on fan speed, with an absorbed power of 36 watts at maximum. Never connect the Turbo Vent to 230V mains power. Installation should be carried out by someone competent in 12V electrical systems, and it's advisable to test the unit before permanently bonding it to your roof.
