Why does fan speed increase after cleaning?

Basically, the clean fans blew air down. THEN as the dust built up on the fans, the effective angle changed so drastically, the fans began to pull air up from the ground.

How do you keep fan blades from getting dusty?

To reduce future dust buildup, Vila recommends using a dust-repelling spray like Endust (or a DIY version: one part liquid fabric softener to four parts water). Spray it on a microfiber cloth and wipe both sides of the blade. Motor: Wipe the pull chain and the motor housing with a clean cloth.

Why do fans slow down over time?

The capacitor on an electric fan is called a run capacitor, as opposed to a start capacitor that gives the needed extra torque for some motors to start. When the capacitor burns out, the electric current through the coil is too steady to generate torque, and the fan slows down and stops.

Why fan blades are more dust at the edges?

“The leading edge of the blades usually develops the thickest layer of dust. That’s because the leading edge [the edge first cutting the air as the blade spins] encounters the most friction and develops the largest charge. “So the dust doesn’t collect on the blades simply by `falling’ or landing on them.

Why is it important to clean your fan?

Two: Decreases Air Quality Another very important reason to clean your fans before you turn them on this summer is because dirty fans can actually decrease the air quality in your home. Fan blades can also have allergens, dust, and mold on them.

What happens if you don’t clean a fan?

Whether it is on or off, your fan will collect dust. But, if you don’t clean your fan, it will continue to circulate dust throughout your home – and you don’t want to be breathing in those harmful particles. Excess dust can also overwork the motor, which will shorten its life span and may cause damage.

How do you keep fan blades clean?

Fan blades should be dusted weekly. You can purchase a specialized pole duster that slides over fan blades, simultaneously cleaning both the top and bottom. For deeper cleaning, position a step ladder beneath the fan and carefully go over the blades with a water-moistened microfiber cloth or terry towel.

But, if you don’t clean your fan, it will continue to circulate dust throughout your home – and you don’t want to be breathing in those harmful particles. Excess dust can also overwork the motor, which will shorten its life span and may cause damage. It doesn’t take much dust to have a measurable effect.

Why do fans fan blades go to zero at the surface?

In spite of the fact that the fan blade is moving at high speed through the air, the speed of the air relative to the fan blade goes to zero right at the surface. So the very smallest dust particles are not disturbed” Air close to fan surface is slowed down due to friction.

Why can’t dust be blown out of a fan?

The effect of retardation of air reduces as we go away from the fan surface. So air is moving faster a bit above the fan surface. If dust piles up to this height, it will be blown away. But dust very close to fan blades can’t be blown off because air itself isn’t blowing at all there.

What is the purpose of fan blade alignment?

These are usually set a certain distance apart. This is known as the alignment. The purpose of that design is to make the fan more efficient. When the blades all work together, then that assures that the fan will move the most air. Here is another interesting video on how a fan blade is designed.

What is the best blade size for a fan?

The most popular however remain as the 5-blade option. That really is the optimum for a high performance fan. The size of the fan is however important to note. Trying to cram a large number of blades into a small circle or diameter is not that practical.
