✦ What problems does this air circulation fan solve for you?

• After turning on the air conditioner, cold air only stays in the upper part of the room, while the floor and corners remain stuffy and hot, leading to low efficiency in using heating/cooling and high electricity bills.
• Ordinary fans can only blow straight air, failing to effectively drive air convection throughout the entire room, making indoor air stale and stagnant.
• Fans occupy floor space at home, and you want to keep your tabletop tidy, making it difficult to meet the flexible needs of different usage scenarios.
• Using a fan at night is too noisy and affects sleep, or the room temperature increases due to motor heat.
• Ordinary fans are difficult to clean, and accumulated dust causes hygiene concerns, making the cleaning process time-consuming and troublesome.

✦ Complete analysis of core functions

① BLDC Inverter Motor — Triple advantages of low noise, low heat, and optimal power consumption

The BLDC (Brushless DC) motor is the core technical foundation of the LUMENA FAN GRANDE C, featuring fundamental technical differences from traditional AC motor fans:

• Low noise, does not affect sleep and daily life: BLDC brushless motors have no mechanical friction noise during operation because there is no physical contact between brushes and commutators. The overall operating sound is much lower than traditional AC motor fans of equivalent power, making it comfortable and quiet even when used during sleep at night.
• Low heat, does not increase indoor temperature: The energy conversion efficiency of BLDC motors is much higher than traditional motors. Most of the electrical energy is directly converted into wind energy, resulting in extremely low motor heat generation. This prevents the indoor temperature from rising due to continuous motor heat, making the air conditioner more efficient.
• Rated power of only 20W, ultra-energy-saving and low power consumption: Compared to the 50-80W power consumption of traditional floor fans, the 20W rated power of the LUMENA FAN GRANDE C means significantly reduced electricity costs for the same airflow capacity. The electricity expenditure for continuous 24-hour operation is extremely low, making it hassle-free for long-term use.

② Wind speed up to approximately 18m/s · Duct fan structure — Powerful directional airflow drives whole-room circulation

• 3-blade fan + duct fan dual structure generates powerful directional airflow: The LUMENA FAN GRANDE C adopts a composite structure design combining a 3-blade fan with a duct fan. The duct structure concentrates the airflow to form a high-speed directional air column, providing a long-range and strong penetrating airflow, with wind speeds reaching up to approximately 18m/s.
• Fundamental difference between air circulation fans and ordinary fans: Ordinary electric fans blow out dispersed wide-angle weak air, mainly to make the skin feel cool; air circulation fans blow out strong, concentrated directional airflow, which directly hits the walls to form a three-dimensional air circulation indoors, truly making the air flow throughout the entire room, making them the best auxiliary tool for heating and cooling.
• Rapidly drives whole-room air convection, significantly improving heating and cooling efficiency: When used with air conditioning, the circulation fan quickly and evenly disperses the cold air from the air conditioner to every corner of the room, making the cooling effect faster and more uniform. At the same room temperature, the air conditioning setting can be raised by 1–2°C, further saving electricity costs.

③ 120° Wide-angle automatic oscillation — Three-dimensional airflow balances whole-room temperature and humidity

• 120° automatic left and right oscillation, extremely wide airflow coverage: The 120° automatic oscillation angle allows the circulation fan to deliver powerful airflow to most corners of the room without moving the unit, effectively balancing the temperature and humidity distribution in various indoor locations.
• Maximizes heating and cooling assistance effects: When air conditioning is on, cold air, being denser, naturally sinks to the floor; when heating is on, warm air, being less dense, naturally rises to the ceiling. The 120° wide-angle circulating airflow forces the upper and lower air layers to mix, completely eliminating temperature stratification, thereby improving both the comfort and efficiency of heating and cooling.

④ Innovative plug-in support rod — Flexible switching between floor-standing and tabletop use with one unit

• Plug-in design makes height adjustment and function switching extremely convenient: The support rod features an innovative plug-in design, allowing for quick switching between one height (approx. 558mm tabletop height) or two heights (up to 800mm floor-standing height) without tools. It can also be used as a pure tabletop circulation fan by directly removing the support rod.
• Two heights cover different usage scenarios: The tabletop height (558mm) is suitable for placing on desks, dressing tables, or kitchen countertops, for localized air circulation; the floor-standing height (800mm) is suitable for use on the floor in living rooms or bedrooms, working with air conditioner outlets to drive whole-room three-dimensional circulation.
• Flexibly adapts to different home space needs: No need to purchase two different appliances; one LUMENA FAN GRANDE C can be flexibly applied in various home scenarios, making home space utilization more flexible and efficient.

⑤ 5 wind speeds + natural wind mode · Power-off speed memory — Smart personalized user experience

• 5-speed precise adjustment: 5 precise adjustments from the lowest silent wind speed to the highest powerful circulation wind speed, meeting different needs from silent sleep mode to rapid whole-room air circulation.
• Natural wind mode simulates outdoor breeze sensation: The natural wind mode makes the wind speed irregularly cycle between high and low speeds, simulating the irregular sensation of a natural breeze, which is more comfortable and natural than the mechanical feel of a fixed wind speed, and less likely to cause discomfort during prolonged use.
• Power-off speed memory design: Automatically resumes the last set wind speed when powered on again, eliminating the need to readjust every time, making it more convenient and intuitive to use.

⑥ Magnetic remote control — Convenient storage, ready to use

• Infrared wireless remote control, easily operable from sofa or bed: No need to get up and walk to the fan for adjustment; you can control wind speed, oscillation, and timer settings from the sofa or bed.
• Magnetic base design, remote control never gets lost: When not in use, the remote control can be directly magnetically attached to the fan base, always in a fixed location, so you'll never search for it around the house again.

⑦ 1/2/4/8 hour timer — Energy-saving and safe automatic shutdown

• Four-stage timer for flexible selection, energy-saving and safer: You can set it to automatically shut off after 1, 2, 4, or 8 hours according to your actual needs. When sleeping at night, setting a timer allows the fan to automatically stop after you fall asleep, avoiding unnecessary electricity consumption and discomfort from excessive airflow throughout the night.

⑧ Detachable design — Fully disassembled for easy and hygienic cleaning

• Front and rear grilles, fan blades, and fasteners are all safely detachable: After long-term use, dust will accumulate on the grilles and fan blades. The detachable design allows each component to be independently removed for cleaning with water or a damp cloth, making the cleaning process safe and convenient. No need to worry about accumulated dust affecting indoor air quality.

✦ Q&A

Q: What is the difference between an air circulation fan and a regular electric fan? I already have air conditioning, do I still need a circulation fan?

A: A regular electric fan blows out dispersed, wide-angle weak air, primarily to make the skin feel cool; an air circulation fan blows out a high-speed, concentrated directional air column, aiming to truly circulate the air throughout the entire room. If you already have air conditioning, the greatest value of a circulation fan is this: the cold air produced by the air conditioner, being denser, naturally sinks and accumulates on the floor, leaving the ceiling area still stuffy. The powerful airflow of the circulation fan forces the upper and lower air layers to mix, making the air conditioning effect faster and more evenly distributed throughout the room. For the same level of comfort, the air conditioner can be set to a higher temperature, saving electricity. The LUMENA FAN GRANDE C's ultra-low power consumption of 20W, combined with the electricity savings from improved air conditioning efficiency, often results in lower overall electricity costs over long-term use than without a circulation fan.
