NanLaew Posted September 7, 2019 Share Posted September 7, 2019 I only buy Hatari brand fans as spare parts for those are readily available at Amorn. Returning to the clan cave after several years, noted that some floor fans were slow and noisy. Replaced the start capacitors (50 to 80 baht at Amorn), cleaned the housing, cage and blades, replacing one that had a cracked hub and they're good for another +million hours. I've never had to replace a motor or grease a bearing (they're sealed anyway) and some of these fans are over 12 years old. However, the gearboxes are the next weak link. Once again available at Amorn but make sure you get the ones with an alloy metal casing. The plastic cased ones don't last. Link to comment Share on other sites More sharing options...

I put the dead or dying in the bin and buy new ones. Pretty sure someone will extract the binned ones and recycle them for fun and/or profit. Win-win situation.

Just clean them when dirty and make sure fan blade is tight. They get loose although I don't know why. They have a reverse thread that should tighten, not get loose. Look for sales. I buy them for 299-399 for the 16" on sale. Buy 2 or 3. I think the bearings are sealed so I don't know if oil will help. I don't oil them.

It works fantastically well, but nowadays I just let others that need em pick them up outside and use them as well as repair them. Same with computers, phones, freezers, refrigerators and TV.

I have too much obviously.

thailand49 Posted September 7, 2019 Share Posted September 7, 2019 I have close to twenty fans throughout the house majority some standing some mounted on the wall run by remotes. The only brand I buy is Hatari and currently replacing all the wall mounts ones that are string operation instead of remote the remote one seem to break down like the swing feature etc. so not I just keep them simple. Once a month majority I clean soap them down and rinse off take me 5 minutes to do one! Many of the fans I have are close to 10 years and still looking and running like new. I spray a bit of silicone where the blade is attached never mess with the motor. Link to comment Share on other sites More sharing options...
atyclb Posted September 7, 2019 Share Posted September 7, 2019 can spray electrical parts cleaner on the rotor while spinning. would be careful not to let spray stream touch hot wire. use teflon high tech lube on bearings and spinning parts. clean all dirt and dust first.

xtrnuno41 Posted September 7, 2019 Share Posted September 7, 2019 Like some sad , take it apart, wash and put some oil on bearings. Also look at the end of motor which has cooling fan for motor. If that one gets dirty, you have less flow to cool motor and temp will go up and at one point will break down motor. That is with many motors. IF you have computer, you also should clean inside the fans and outlets. You should take apart cpu fan, video card and outlet fan, fan of power supply and clean all. DOnt forget to put new thermal paste back on cpu cooler. However it is maybe "frightening" for someone dont know about this, but it is essential. You have to handle carefully.

Jaxxper Posted September 7, 2019 Share Posted September 7, 2019 We just clean and oil our floor fans regularly. Ceiling fans seem to go on forever so service of them is just limited to cleaning the crud that the blades pick up. Link to comment Share on other sites More sharing options...
crazykopite Posted September 7, 2019 Share Posted September 7, 2019 I have Mr Ken ceiling fans fully remote 6 speed super super quiet they are ac to dc cost 5,000 baht+ but worth every baht as I use them a lot I just wipe them with a damp cloth once a month best fans I have ever owned and because the reduce to DC there is less wear on them they are wooden but sprayed in a beautiful silver colour. Had them in for two years and they are as new as when purchased. The shape of the blade gives better air flow and you can also change the direction of the fan rotation by remote control Link to comment Share on other sites More sharing options...

RideJocky Posted September 7, 2019 Share Posted September 7, 2019 Dust accumulation on the blade and shroud generally will not cause imbalance, as it typically collects evenly. But dust on the blade and or shroud absolutely increases the friction which has a significant negative impact on the performance and the longevity of the motor.Every blade from every reputable manufacturer is tested and spun-balanced before it is sold.Most of the sleeve bearings used (as others have stated) are typically powder-metal, oil-impregnated. This is usually done by loading the newly sintered bearings into a tank of oil and pressurized for a period of time.For high-temp applications we used bearings with 2% moly disulfide powder mixed with stainless powder.Sent from my iPhone using Thaivisa Connect Link to comment Share on other sites More sharing options...
