HKM-770451 39 Inch Touch Screen Bladeless Oscillating Air Cooler Tower Fan with Remote Control and Timer Function for Home and Office
HKM-770451
24-Hour Timer, 39-Inch Tower
The HKM-770451 is a bladeless tower fan that pushes a steady column of air through a tall, slim body. The tower runs in matte plastic with a slim vertical profile. Airflow is set at multiple speed levels through remote control, with a timer that runs up to 24 hours. Noise stays from 32 db on the lowest setting, quiet enough for bedrooms and study corners. Available in White and Black, it tucks beside a bed, desk or sofa without claiming much floor.
Key Features
Six details that make the HKM-770451 a dependable everyday companion.
Brushless Motor
A brushless DC motor drives the HKM-770451, so it runs smoother, cooler, and more quietly than a conventional AC fan while drawing less power. Even on middle levels the stream crosses a standard room.
Quiet Operation
At low speed the HKM-770451 holds noise around 32 dB - quiet enough for a bedroom, nursery, or late-night desk session without disturbing anyone. Quiet enough for calls and naps.
Multiple Speeds
Multiple fan speeds let you dial the airflow from a whisper-soft breeze for sleep to a strong cooling stream on the hottest days. The steps between levels stay gentle.
Wide Coverage
The HKM-770451 is shaped to circulate air across a wide area, so the whole room feels cooler instead of just the spot directly in front of it. One unit covers a bedroom or study.
Natural Breeze Feel
The airflow is designed to feel like a natural, comfortable breeze rather than a sharp, blasting jet - easier on the skin and the ears. Even on middle levels the stream crosses a standard room.
24-Hour Timer
Set the built-in timer for up to 24 hours and the fan switches itself off automatically after you have fallen asleep or left the room. The timer handles the shut-off.
Overview
A tower fan, bladeless airflow, quiet operation and a built-in timer.
The HKM-770451 is a bladeless tower fan built to move air quietly through bedrooms, offices, and living spaces. It uses remote, touch controls. A built-in timer runs up to 24 hours, so the fan can switch off on its own. Available colors include white and black. Engineered for quiet, consistent comfort in any room. Setup stays minimal, and routine care is a quick wipe with a soft, dry cloth. Quiet operation is part of the design, so it fits into sleep and work routines without intrusion. The housing runs in impact-resistant ABS with a weighted base that keeps the column steady on hard floors. Through the summer it works as the main cooling fan; in shoulder seasons it moves stale air out of a closed room in minutes.
Quiet Comfort by Design
A Bladeless Tower Fan built around how it actually gets used.
The HKM-770451 pairs bladeless airflow with a slim, modern silhouette that fits easily into a living room, bedroom, or office. Every detail, from the control layout to the airflow path, is designed for daily use: the controls sit where.

Daily Use And Care
A short routine keeps the fan quiet and the airflow strong.
Keeping the HKM-770451 in good shape takes very little effort. Wipe the intake vents and the outer surface with a soft, dry cloth every week or two, and keep the unit on a level, stable surface where air can move freely. Avoid spraying liquids directly onto the fan, and never let moisture reach the controls or the power connection. When the season ends, store the fan in a cool, dry place away from direct sunlight so the finish and the cable stay in good condition.

Why Choose the HKM-770451
Six further reasons the HKM-770451 earns its place in the room.
Quiet, Smooth Air
The HKM-770451 is built around steady, low-noise airflow that feels natural rather than blasting - the kind of breeze you can sit in for hours. Quiet enough for calls and naps.
Bedroom-Proof Quiet
At around 32 dB at low speed, it will not disturb sleep, study, or video calls - you can run it all night without noticing it is on. Quiet enough for calls and naps.
Efficient BLDC Motor
Brushless DC power means less energy use, less heat, and a longer service life than AC fans - it pays for itself in lower bills over time. The stream is tuned for reach, not drift.
Whole-Room Coverage
The airflow pattern reaches across the room rather than just one chair, so the whole space stays comfortable even from a corner position. One unit covers a bedroom or study.
Control from Your Seat
Adjust speed, timer, and oscillation from across the room with the included remote - no need to get up mid-conversation or mid-movie. Daily use comes down to one button.
Set-and-Forget Timer
Program up to 24 hours and let the fan switch off on its own - fall asleep or head out without worrying about it running all day. The timer handles the shut-off.
Frequently Asked Questions
Quick answers about the HKM-770451 tower fan.
Does it reach across a room?
"Bladeless" refers to the absence of visible external fan blades. Inside the tower, a high-efficiency impeller draws air into the base and accelerates it through a narrow annular aperture. As the air exits, it adheres to the curved surface of the duct via the Coandă effect, entraining surrounding air and multiplying total output volume. The result is smooth, powerful airflow without the safety hazards or cleaning challenges of exposed blades.
What room size does it suit?
The HKM-770451 performs ideal in rooms up to approximately 350 sq ft (32.5 m²). In larger open-plan areas, it provides excellent spot cooling and, with oscillation enabled, can effectively circulate air across wider zones. For spaces exceeding 500 sq ft (46.5 m²), we recommend positioning the unit centrally or near the area where you spend the most time to maximize perceived cooling comfort.
Is it quiet enough for a bedroom?
In Sleep Mode at its lowest speed setting, the HKM-770451 produces approximately 28-32 dB of sound - comparable to a soft whisper or the rustle of leaves. The bladeless duct and internally dampened motor chamber significantly reduce high-frequency noise, leaving a low, unobtrusive hum that most users find non-disruptive. At maximum speed, sound levels remain below 52 dB, roughly equivalent to moderate rainfall.
How does the timer work?
Absolutely. The 24-hour timer allows you to program the fan to shut off automatically after a set duration. For overnight use, we recommend setting the timer to 6-8 hours in Sleep Mode - this ensures gradual speed reduction as the night progresses, preventing overcooling while conserving energy. The fan will power down automatically once the timer expires.
Does it reach across a room?
Maintenance is refreshingly simple. Wipe the exterior with a soft, dry microfiber cloth to remove dust. For the air intake vents located near the base, use a vacuum cleaner with a brush attachment every 2-4 weeks to prevent dust buildup. The bladeless design means there are no grilles to disassemble or blades to clean individually. Avoid using water or liquid cleaners directly on the unit.
Does the remote need line of sight?
The included remote uses infrared (IR) technology, which requires a reasonably clear line-of-sight to the front of the tower where the IR receiver is located. The effective range is approximately 20 ft (6 m) within a 30-degree cone. For ideal results, aim the remote toward the LED display area. The magnetic storage feature on the rear of the tower ensures you always know where to find it.
Quick Troubleshooting
Common HKM-770451 issues and what to check first.
The fan does not turn on.
Check the outlet with another device to confirm it has power, and make sure the plug is fully seated at both ends. Set the speed control to an active level rather than off. Rechargeable models: confirm the battery has charge and give it a full charge before first use. If the fan still does not respond, contact support and include the model number HKM-770451. If the fault persists, unplug for ten minutes and retry from the lowest speed. Anything still unclear goes to support with HKM-770451.
The airflow feels weaker than before.
Confirm the speed setting is where you expect it, then clean the intake grille and any dust from the blades or vents. Make sure nothing blocks the front or rear of the fan, and keep it a short distance from walls so air can circulate freely. A quick cleaning usually restores normal airflow; if it does not, contact support. Still stuck? Unplug for ten minutes, retry from speed 1. If it returns, message support with HKM-770451 and a short note.
The fan makes an unusual noise.
Turn the fan off and unplug it before inspecting. Check the grille and vents for packaging residue or loose parts near the blades, and confirm the unit sits on a level, stable surface. Reinstall any removable parts fully. If a noise persists after these checks, stop using the fan and contact support with the model number HKM-770451. If none of this clears it, unplug for ten minutes and try once more. Persistent faults go to support with HKM-770451.
The remote is not responding.
Replace the remote battery with a fresh one and point the remote directly at the receiver window on the fan. Remove obstacles between the remote and the unit, and stay within the normal operating range. If the fan responds to its own controls but not the remote, a battery swap almost always solves it. Contact support if the problem continues. If the fault persists, unplug for ten minutes and retry from the lowest speed. Anything still unclear goes to support with HKM-770451.
