5000 seriesTower Fan

I have 2 of this Philip 5000 series CX5535 tower fan, it is located at two different room/area. I use it daily to get airflow moving within a room for my furkiddo’s comfort as Malaysia is always “summer” :-) . I do not use the ceiling fan as this energy saving tower fan does the job. It’s one of the best tower fan, but due to it suddenly stop within a day when turn off, i do not know the exact hours it auto shut off even without turning on the timer. But definitely within a day (if i did not do a force “on & off” using the tower fan power button), it will just turn itself off. I’m not sure if that is Philips default mechanism to avoid overheating or any reason but this behaviour is same with both of my CX5535. To avoid it to stop, i will always need to power on/off before i go to sleep & another time before i go to work, but i do not have any alternative when i’m outstationed hence the solution was to get another brand brand fan (vornado to be specific). Pros : Wind is powerful Minimum noise Oscillating is acceptable Light weight hence easy to move location (as long near power adapter) Cons: Auto shut off within a day even the timer was not set
