The air conditioner blower is one of the many unique parts in an aircon unit that contributes to the production of cool and clean air. But did you know that aside from producing air inside the system, the blower is also responsible for promoting proper air movement to keep the machine running smoothly?

In this article, we’ll take you through the main functions and the different types of the blower or the air conditioner fan — including a step-by-step guide on how to clean one.

How Does an Aircon Blower Work?

The blower works by transferring the warm air away from any space in the unit and replacing it with cold air. It facilitates proper airflow in the unit for better circulation and machine performance.

However, blowers don’t normally come in one size or type. There are different forms and sizes of these fans, depending on the air conditioning system. Read more below about the different types of the blower.

The Different Types of an Aircon Blower

1. Propeller Fan

‍

The propeller fan is one of the most common blower types in an air conditioning system. It usually comes in the form of a disk-type wheel and placed on a circular plate alongside a belt-driven motor. This fan type is usually present in standard split air conditioners commonly used by offices and establishments.

Since this aircon fan type is known to emit a significant amount of noise, it’s always installed and found in high-level places won’t affect human activity, such as rooftops and window sides.

2. Centrifugal Fan

‍

The aircon centrifugal fan is a compact and powerful blower that’s considered more capable than a lot of aircon blowers. It’s used in air-handling units and has an appearance similar to water wheels or hamster wheels and is known to use higher pressure when in use. But because it uses more force and pressure than other blowers, it also makes a lot of noise and can only be installed in the strictest of settings where there’s no human activity. 

3. Vane-axial Fan

‍

The aircon vane-axial fan bears a similar appearance to that of a standard fan wheel. It normally comes in the shape of a disk and housed in a secure cylinder tube. The fan is also protected by multiple air guide vanes in the tube to facilitate proper airflow.

4. Tube-axial Fan

‍

The aircon tube-axial fan is a common fan type for the air conditioning system. It has an exterior and structure similar to a normal car tire and can usually be found in different sizes — from small and compact to bulky and large.

How To Clean Aircon Blower: 5 Easy Steps

Cleaning your dirty or dusty air conditioner blower? Here are 5 quick and easy steps:

1. Begin the process by flipping the cover of the air conditioner machine to access the washable filters. Use clean water, soap and a cleaning pad.
2. Remove the flap and the air vanes from the unit to access the impeller.
   
3. Clean the impeller with a half-inch paint brush. This will remove any type of dust or dirt that have accumulated over time. Make sure to do this gently and thoroughly.
   
4. Use a damp rag or cloth to get rid of any additional dirt or debris. Get another clean rag to wipe away the entire surface of the impeller until clean.
   
5. To get rid of all debris, simply turn on the air conditioner unit and let it blow all dirt outside the vent. Use a vacuum cleaner or a handy sweeper afterwards to clean everything.
