✦ What problems does this air circulator 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 AC and heating, and high electricity bills.

• Ordinary fans can only blow straight air, failing to effectively drive air convection throughout the entire room, leaving the indoor air stagnant and stuffy.

• Fans occupy floor space at home, but you also want to keep your tabletop tidy, making it difficult to meet flexible needs for different usage scenarios.

• Using a fan at night produces excessive noise that affects sleep, or the motor generates heat, causing the room temperature to rise instead.

• Ordinary fans are difficult to clean, and accumulated dust poses hygiene problems, making the cleaning process time-consuming and troublesome.

✦ Core Functions Fully Explained

① BLDC Inverter Motor — Triple Advantages of Low Noise, Low Heat, and Optimal Power Consumption

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

• Low noise, no impact on sleep and daily life: BLDC brushless motors operate without mechanical friction noise because they lack physical contact between brushes and commutators. Their overall operating sound is much lower than that of traditional AC motor fans of the same power, making them comfortable and quiet even when used for sleeping at night.

• Low heat generation, does not increase indoor temperature: The energy conversion efficiency of BLDC motors is much higher than that of traditional motors. Most of the electrical energy is directly converted into wind energy, resulting in extremely low heat generation from the motor. This prevents the indoor temperature from rising due to continuous motor heat, making air conditioning 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 LUMENA FAN GRANDE C's 20W rated power means a significant reduction in electricity costs for the same air delivery capacity. The electricity expenditure for continuous operation 24 hours a day is extremely low, allowing for worry-free long-term use.

② Air 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 with a 3-blade fan combined with a duct fan. The duct structure concentrates the airflow to form a high-speed directional air column, providing a long air throw distance, strong penetrating power, and air speeds up to approximately 18m/s.

• Fundamental difference between air circulators and ordinary fans: Ordinary electric fans emit dispersed, wide-angle, weak airflow, primarily providing a cooling sensation to the skin. Air circulators, however, emit powerful, concentrated, directional airflow that directly impacts walls, creating a three-dimensional air circulation throughout the room. This truly moves the air in the entire room, making it the best auxiliary tool for air conditioning and heating.

• Rapidly drives whole-room air convection, significantly improving air conditioning efficiency: When used with air conditioning, the circulator 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.

③ 120° Automatic Oscillation — Three-Dimensional Air Delivery Balances Whole-Room Temperature and Humidity

• 120° automatic left-right oscillation, extremely wide air coverage: The 120° automatic oscillation angle allows the circulator to deliver powerful airflow to most corners of the room without moving the unit, effectively balancing temperature and humidity distribution throughout the indoor space.

• Maximizes air conditioning and heating assistance effect: When the air conditioner is on, cold air, being denser, naturally sinks to the floor; when the heater is on, warm air, being less dense, naturally rises to the ceiling. 120° wide-angle circulating air delivery forces the mixing of upper and lower air, completely eliminating temperature stratification, thereby improving both comfort and efficiency of air conditioning and heating.

④ Innovative Plug-and-Pull Support Rod — Flexible Switching Between Floor and Tabletop Use

• Plug-and-pull design makes height adjustment and function switching extremely convenient: The support rod features an innovative plug-and-pull design, allowing for quick switching between one-stage height (approx. 558mm tabletop height) or two-stage height (up to 800mm floor-standing height) without tools. The support rod can also be removed directly for use as a pure tabletop circulator.

• Two height options cover different usage scenarios: The tabletop height (558mm) is suitable for placing on desks, dressing tables, or kitchen countertops, targeting air circulation in specific areas; the floor-standing height (800mm) is suitable for use on the floor in living rooms or bedrooms, working with air conditioner outlets to drive three-dimensional circulation throughout the entire room.

• Flexible adaptation 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 Fan Speeds + Natural Wind Mode · Off-State Fan Speed Memory — Smart Personalized User Experience

• 5-stage precise fan speed adjustment: From the lowest silent fan speed to the highest powerful circulation fan speed, there are 5 precise adjustment stages to meet various needs, from silent sleep mode to rapid whole-room air circulation.

• Natural wind mode simulates outdoor breeze sensation: The natural wind mode irregularly cycles between high and low fan speeds, simulating the irregular sensation of a natural breeze. This is more comfortable and natural than the mechanical feel of a fixed fan speed, preventing discomfort during long periods of use.

• Off-state fan speed memory design: Each time the fan is turned on again, it automatically resumes the fan speed setting from before it was turned off. There's no need to readjust it 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 the sofa or bed: No need to get up and approach the fan to adjust it. You can control fan speed, oscillation, and timer settings remotely from the sofa or bed.

• Magnetic base design, no more lost remote controls: When idle, the remote control can be directly magnetically attached to the fan's base, always in a fixed location, eliminating the need to search for it all over the house.

⑦ 1/2/4/8 Hour Timer — Energy-Saving Automatic Shut-off for Safety

• Four-stage timer for flexible selection, energy-saving and safer: You can set it to automatically turn off after 1, 2, 4, or 8 hours as needed. When sleeping at night, setting the timer ensures the fan stops automatically after you fall asleep, avoiding unnecessary electricity consumption and discomfort from excessive airflow throughout the night.

⑧ Detachable Design — Fully Disassembled for Easy Cleaning and Hygiene Maintenance

• Front and rear grilles, fan blades, and fixing clips are all safely detachable: After prolonged use, dust can accumulate on the grilles and fan blades. The detachable design allows each component to be removed independently for cleaning with water or a damp cloth. The cleaning process is safe and convenient, eliminating worries 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: Regular electric fans produce dispersed, wide-angle weak breezes, primarily to create a cooling sensation on the skin. Air circulation fans produce a high-speed, concentrated directional air column, designed to genuinely move the air throughout the entire room. If you already have air conditioning, the greatest value of a circulation fan is that 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 mixing of upper and lower air layers, 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 in the long run compared to not using a circulation fan.
