LUMENA Korea FAN GRANDE C BLDC Air Circulation Fan | Flexible Height Adjustment · Low Noise & Energy Saving · High Airflow & Wide-Angle Auto Oscillation | Air Circulation Fan

The ultimate question regarding air circulators has never been "is it cool enough," but rather "can the air truly circulate throughout the entire room." The LUMENA FAN GRANDE C BLDC is powered by a high-quality BLDC inverter motor, driving a powerful 18m/s directional airflow. Its 120° wide-angle 3D oscillation rapidly induces whole-house air convection—combined with an ultra-energy-efficient design featuring a rated power of only 20W, it can run all day without the burden of high electricity bills.

The LUMENA FAN GRANDE C BLDC air circulator utilizes an innovative detachable support pole to allow for flexible switching between floor-standing and desktop modes (with two-stage height adjustment up to 800mm). The BLDC inverter motor provides low noise and low heat generation, with an ultra-efficient 20W rated power. Its 3-blade design combined with a duct fan structure generates a powerful airflow of approximately 18m/s. The 120° automatic wide-angle oscillation drives whole-house air circulation, featuring 5 speed settings + natural wind mode, and a power-off speed memory function. It includes a magnetic remote control with infrared wireless operation, 1/2/4/8-hour timers, and a detachable front/rear grille and blade design for full cleaning. The Korean minimalist aesthetic blends perfectly into any home decor.

✦ What problems does this air circulator solve for you?

• After turning on the AC, the cold air stays at the top of the room while the floor and corners remain stuffy; heating/cooling efficiency is low, and electricity bills remain high.
• Standard fans only blow air in a straight line, failing to effectively induce whole-house air convection, leaving indoor air stagnant.
• Fans occupy floor space, but you also want to keep your desktop tidy; it is difficult to balance flexible needs for different usage scenarios.
• Excessive fan noise at night disrupts sleep, or the motor generates heat that actually raises the room temperature.
• Standard fans are difficult to clean; dust accumulation causes hygiene issues, and the cleaning process is time-consuming and cumbersome.

✦ Full Analysis of Core Features

① BLDC Inverter Motor — Three-fold benefits: Low Noise, Low Heat, Optimal Power Consumption

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

• Low noise, won't affect sleep or daily life: Because BLDC brushless motors have no physical contact between brushes and commutators, there is no mechanical friction noise during operation. The overall operating sound is much lower than traditional AC motor fans of the same power, making it comfortable and quiet for use while sleeping at night.
• Low heat, won't increase indoor temperature: The energy conversion efficiency of a BLDC motor is far higher than that of a traditional motor. Most electrical energy is converted directly into wind energy, resulting in extremely low motor heat generation, which prevents the room temperature from rising and increases AC efficiency.
• Rated power of only 20W, ultra-energy-efficient: Compared to the 50–80W power consumption of traditional floor fans, the LUMENA FAN GRANDE C’s 20W rating means significantly lower electricity costs for the same airflow capability. The electricity cost for 24-hour continuous operation is extremely low, making it worry-free to run for long periods.

② Airflow up to approx. 18m/s · Duct Fan Structure — Powerful directional airflow to drive whole-house circulation

• 3-blade fan + duct fan dual structure generates powerful directional airflow: The LUMENA FAN GRANDE C adopts a composite design combining 3 fan blades with a duct fan structure. The duct design concentrates airflow to form a high-speed directional air column with a long, powerful reach and high penetration, achieving wind speeds of up to approximately 18m/s.
• The fundamental difference between air circulators and ordinary fans: Ordinary electric fans blow weak, wide-angle air mainly to provide a cooling sensation on the skin. Air circulators blow strong, concentrated, directional airflow that hits walls to create 3D indoor air circulation, making the air in the whole house truly flow. It is the best auxiliary tool for heating and air conditioning.
• Rapidly drives whole-house air convection, significantly improving heating/cooling efficiency: When used with air conditioning, the circulator rapidly and evenly disperses the cold air from the AC to every corner of the room, making cooling faster and more uniform. At the same room temperature, the AC set temperature can be increased by 1–2°C, further saving electricity.

③ 120° Wide-Angle Automatic Oscillation — 3D airflow to balance temperature and humidity in the whole room

• 120° automatic horizontal oscillation, extremely wide coverage: The 120° automatic oscillation angle allows the circulator to reach most corners of the room without moving the unit, effectively balancing temperature and humidity distribution throughout the indoor space.
• Maximizes heating/cooling assistance: When the AC is on, cold air naturally sinks to the floor due to its higher density; when the heater is on, warm air naturally rises to the ceiling due to lower density. The 120° wide-angle circulation forces upper and lower layers of air to mix, completely eliminating temperature stratification and simultaneously improving comfort and efficiency.

④ Innovative Detachable Support Pole — Flexible switching between floor and desktop use in one device

• Detachable design makes height adjustment and function switching extremely convenient: The support pole features an innovative plug-and-pull design, allowing for quick switching between stage-one height (approx. 558mm for desktop) or stage-two height (up to 800mm for floor-standing) without tools. The pole can also be removed entirely for use as a dedicated desktop circulator.
• Two heights cover different usage scenarios: The desktop height (558mm) is suitable for desks, vanity tables, or kitchen countertops for targeted air circulation. The floor-standing height (800mm) is suitable for living rooms or bedrooms to work with AC outlets for whole-room 3D circulation.
• Flexible adaptation to different home space requirements: There is no need to buy two different appliances; a single LUMENA FAN GRANDE C can be flexibly applied in various home scenarios, making space usage more efficient.

⑤ 5 Speed Settings + Natural Wind Mode · Power-off speed memory — Intelligent, personalized user experience

• 5-speed precise adjustment: Includes 5 levels of precise adjustment, from the lowest silent speed to the highest powerful circulation speed, meeting needs from silent sleeping modes to rapid whole-house circulation.
• Natural wind mode simulates a outdoor breeze: The natural wind mode cycles irregularly between high and low speeds, simulating the irregular feel of a natural breeze, which is more comfortable and natural than the mechanical feel of a fixed speed, preventing discomfort during prolonged use.
• Power-off memory design: Each time it is turned back on, it automatically restores the speed setting from the last time it was powered off, making it more intuitive and convenient to use without needing to re-adjust.

⑥ Magnetic Remote Control — Convenient storage, always within reach

• Infrared wireless remote control, easy to operate from sofa or bed: No need to get up and walk to the fan; adjust speed, oscillation, and timer settings directly from your sofa or bed.
• Magnetic base design means no more lost remotes: When not in use, the remote can be attached directly to the fan base, ensuring it stays in a fixed spot so you no longer have to search for it around the house.

⑦ 1/2/4/8-hour Timer — Energy-saving and safe automatic shut-off

• Flexible four-stage timer for energy savings and safety: You can set the fan to shut off automatically after 1, 2, 4, or 8 hours. Setting the timer for sleeping at night allows the fan to stop automatically once you fall asleep, avoiding unnecessary electricity usage and the discomfort of excessive wind exposure throughout the night.

⑧ Detachable Design — Fully dismantlable for easy, hygienic maintenance

• Front/rear grilles, fan blades, and locking clips are all safely detachable: Dust accumulates on the grilles and blades after long-term use. The detachable design allows each part to be removed individually for cleaning with water or a damp cloth, making the process safe and convenient and ensuring you don't have to worry about dust-laden air affecting your indoor air quality.
