Electric desk fans require lubrication to operate smoothly and prevent wear and tear. The type of lubricant used is important, as electric fans operate at high speeds and generate heat, causing certain lubricants to break down. Antique fans used animal fats, while modern fans use refined oils or synthetic lubricants. It's important to refer to the owner's manual for specific instructions and oil recommendations, as some fans may not require oil at all. The process involves turning off the power, cleaning the fan and oil hole, checking oil levels, and applying the appropriate oil. Oiling a fan can help reduce noise, improve performance, and prolong its lifespan.

What You'll Learn
Check if your fan needs oiling
Before oiling your fan, it is important to check if your fan needs oiling. Firstly, consult your user manual to get the maintenance details for your specific model. If your fan requires regular oiling, the manual should state the type of oil and frequency of oiling. If you are unable to locate the oil hole, your fan probably does not need oiling. The oil hole is usually located on top of the motor, near the downrod, and is often labelled.
If you have located the oil hole, the next step is to check the oil level. To do this, you can use a pipe cleaner. Fold the pipe cleaner over to form a hook, and insert it into the oil hole. If the pipe cleaner comes out with oil on it, then your fan does not need oiling. If the pipe cleaner does not touch any oil, then you should proceed to oil your fan.
Additionally, you may notice that your fan has become slower or is making creaking noises. These could be signs that your fan needs oiling or lubrication. If your fan is making noise, it may also be an indication that it needs to be cleaned, as dust and lint can accumulate inside the motor and fan grills.

Turn off the power
Before you begin to oil your electric desk fan, it is imperative that you turn off the power to the room the fan is in. This is a crucial step to ensure your safety and prevent any possibility of electrocution.
To do this, locate your house's breaker box and switch off the appropriate switch. This will cut off the power supply to the fan and the entire room it is in. It is important to verify that you have turned off the correct switch by testing the fan to make sure it does not turn on. This simple test will ensure that you are not inadvertently working with a live electrical current, which can be extremely dangerous.
Another way to confirm that the power is off is to use a handheld circuit tester. This device will allow you to check if electricity is still flowing to the wires, providing an additional layer of safety. By taking these precautions, you can be confident that you have eliminated the risk of electrocution and can proceed with the oiling process safely.
Remember, working with electricity can be hazardous, and it is always better to be cautious. Once you have confirmed that the power is off, you can proceed with the next steps of oiling your electric desk fan, knowing that you have taken the necessary measures to prioritize your safety.

Choose the right lubricant
When it comes to choosing the right lubricant for your electric desk fan, there are several factors to consider. Firstly, it is important to use an oil-based lubricant or one that is specifically designed for fan motor use. Electric fan motors operate at high speeds and generate heat, so the lubricant should be heat-resistant to withstand these conditions.
Another crucial factor is the weight or viscosity of the lubricant. Electric motors typically require a non-detergent variety of oil, as most modern motor oils with detergents can cause issues. Look for a non-detergent, lightweight oil with a viscosity grade of SAE 15 or SAE 20. These grades of oil are suitable for most electric fans and will help reduce noise and wear. If your fan exhibits shaft wear, you may need to use a heavier-grade oil, such as SAE 30, to quiet any knocking or buzzing noises.
It is worth noting that some older fans may require heavier oils. Antique fans, for example, typically work well with SAE 15 oil. Additionally, the type of fan and the materials it is made of can influence your choice of lubricant. If you are lubricating an outdoor fan, you may need a specialised oil like Liberty Oil, which is designed for small motors in outdoor settings.
When selecting a lubricant, consider the application method. Some lubricants come in easy-to-use squeeze bottles, while others have spray nozzles. Squeeze bottles are often preferred for indoor fans to avoid over-application and strong odours. For hard-to-reach areas, consider a lubricant with a telescoping tip, such as the one offered by Supco, which is designed for small motors and is heat-resistant and long-lasting.
Finally, while refined oils are a common choice, they tend to have poor viscosity consistency and can break down more quickly due to heat. Synthetic lubricants, such as RP, are a better option for electric fans as they provide superior performance and longevity.
