The Domus BLAST 48is a 1,220mm three-blade DC ceiling fan with a9-speed remote, reverse winter/summer mode, atropical rating, and an optional 18W LED light kit.

The fan draws 25W, not the 18W our record shows.The datasheet is clear: 25W for the DC motor.

18W is the optional light kit’s wattage, which has found its way into the fan’sown power field. The 52-inch version of this fan records 25W correctly, so it isthis listing rather than the range.

The number that matters is 25W for the fan, plus 18W if you add the light kit about 43W with everything running. That is still remarkably little: a DC fan ofthis size uses roughly a third of what an AC one does, which is the whole reason to buy one.

Why a DC motor is worth the difference

• 25W at full speed against roughly 7080W for a comparable AC fan.Running eight hours a night through a summer, that gap is real.
• Nine speeds instead of three. An AC fan is switched between a few fixed taps; a DCfan is genuinely variable, so the lowest setting is a barely perceptible drift rather thanlow.
• Quieter at low speed, which is what most people actually want overnight.
• A DC fan needs its receiver. Speed is controlled electronically rather than by awall switch, so the remote (or a compatible wall controller) is part of the system, not an accessory. Its warranty is shorter than the fan’s see below.

Three blades at 48 inches, and what it moves

• 1,219mm sweep, 14.5 blade pitch, 13,850m/h airflow.
• 48 inches suits a bedroom or a medium living room roughly up to44m. For a larger room the 52-inch four-blade version moves more air(14,305m/h).
• Three blades versus four is not simply “fewer”. Three blades at the same pitch andspeed move air slightly more efficiently and tend to be marginally noisier at high speed; four aresmoother. At the speeds people actually use, the difference is small.
• Reverse winter mode pushes warm air down off the ceiling in winter at low speed genuinely useful in a room with a high ceiling and a heater.

The warranty is two terms, not one

Our record shows 6 years. The datasheet reads:

That is not a six-year warranty. It is three years where Domus attends, followed bythree years where parts are replaced but the labour is yours and the electronics thatmake a DC fan work carry one year. We would rather set that out than let the summedfigure stand, because the receiver is the part most likely to need attention.

The light kit is optional and separate

• An 18W LED kit with 3000K / 4000K / 5000Kswitchable from the remote, and dimmable from the remote.
• Our record carries the light kit’s colour temperatures and a colour-changing flag on the fanitself. The fan has no light unless you buy the kit.
• Colour and dimming from the remote rather than a dip switch is a real advantage it is adjusted from the bed, not from a ladder.
• Tell us if you want the kit and we will quote them together, so the fan and thelight arrive as one order.

Construction and rating

• ABS polymer motor housing, canopy and blades. Polymer blades do not warp withhumidity the way timber can, and they are light, which is part of what lets a DC motor run soefficiently.
• Tropically rated built for heat and humidity.
• The datasheet gives IPX0, meaning no water protection. Tropicalrating and weather rating are different things: this is an indoor or fully covered fan, not one for anexposed alfresco.
• An extension rod is available for high or raked ceilings ask us, and tellus the ceiling height.

Where it works

• Bedrooms and medium living rooms, roughly up to 44m.
• Rooms where quiet running at low speed matters nine speeds, DC motor.
• Covered alfrescos and humid climates tropically rated, polymer blades.
• Not exposed positions IPX0 means no water protection.
• Not a light on its own the kit is a separate purchase.
• For a larger room, the 52-inch four-blade version moves more air.

Specifying it

1,220mm (48inch) three-blade DC ceiling fan.Sweep 1,219mm, blade pitch 14.5, airflow 13,850m/h, 9 speeds,reversible. Motor 25W our record’s 18W is theoptional light kit’s figure, not the fan’s. 240V AC supply, DC motor.ABS polymer motor housing, canopy and blades. Tropically rated; IPX0 no water protection. 9-speed remote with timer and reverse winter/summermode. Extension rod available. White or black.

Warranty: 3 years in-home + 3 years parts on the fan; 1 year in-home + 1 year parts on thereceiver and remote. Our record’s “6 years” is those two fan terms summed. Optional 18W LED TRIO light kit 3000K / 4000K /5000K switchable and dimmable from the remote, sold separately.

Questions

How much power does the fan use?

25W at full speed, from the datasheet. Our record shows 18W, and that is the optional light kit’s wattage which has found its way into the fan’s power field the 52-inch version of the same fan records 25W correctly. With the light kit fitted and everything running you are at about 43W, which is still roughly a third of what a comparable AC fan draws.

Is the warranty really six years?

No, and this is worth reading carefully. The datasheet gives the fan 3 years in-home plus 3 years parts replacement two different terms, where the second covers the part but not the labour. Our record has summed them to “6 years”. The receiver and remote, which are what make a DC fan work, carry 1 year in-home plus 1 year parts.

What is the advantage of a DC motor?

Power and control. It draws 25W at full speed against roughly 7080W for a comparable AC fan, and it gives nine genuinely variable speeds rather than three fixed taps so the lowest setting is a barely perceptible drift rather than “low”. It is also quieter at low speed, which is what most people want overnight. The trade-off is that speed is controlled electronically, so the remote and receiver are part of the system rather than accessories.

Should I get the 48 inch or the 52 inch?

Room size. The 48-inch three-blade moves 13,850m/h and suits a bedroom or a medium living room up to roughly 4 4m. The 52-inch four-blade moves 14,305m/h and suits a larger room. Three blades against four is a smaller difference than people expect three are marginally more efficient and slightly noisier at high speed, four are smoother, and at the speeds people actually use the difference is small.

Does it come with a light?

No the 18W LED TRIO light kit is a separate purchase. It switches between 3000, 4000 and 5000K and dims, both from the fan’s remote rather than a dip switch, which means adjusting it from the bed rather than from a ladder. Our record carries the kit’s colour temperatures on the fan itself, which is why the page mentions it; the fan has no light until you add the kit. Tell us if you want both and we will quote them together.

Can it go outside?

Under full cover only. It is tropically rated, which means built for heat and humidity, but the datasheet gives IPX0 no water protection at all. Tropical rating and weather rating are different things. A covered alfresco or a verandah with solid roof and walls on two sides is fine; an exposed position is not.

Can I use it on a high or raked ceiling?

Yes an extension rod is available. Tell us the ceiling height and, if it is raked, the pitch, and we will work out the right rod length and whether a sloped-ceiling kit is needed as well. A fan needs air above it as well as below, so on a high ceiling the rod is a performance part rather than just a spacer.
