Centrifugal fans (otherwise known as squirrel cage fans due to their hamster wheel-like appearance) are powerful exhaust fans used to control air pollution and are common in central cooling systems. Proper maintenance of these fans is necessary due to how many internal fan blades they use. One easy way to maintain your fan is by lubricating it occasionally.
Things You'll Need
- Duster or cloth
- Phillips screwdriver
- Industrial spray lubricant
Turn off your fan and unplug it from the outlet to which it is connected.
Use your screwdriver to remove all screws around the housing of the fan. Remove the case of the housing to expose the fan blades inside.
Use a duster or cloth to remove any excess dust from the blades. This will make sure the lubricant won't be obstructed.
Use an industrial, non-grease based lubricant, such as WD-40, to coat the blades of the fan thoroughly. Also make sure to coat the hinges around the fan.
Replace the fan case and plug in the fan.
