Pay Attention to Using an Air Diffuser

Air diffusers are common elements in air conditioning systems and, while they are quite simple elements, they play an important role in the overall efficiency of the air conditioning system. They are cheap, easy to install and the benefits are numerous. Here are the basics that you should know about air diffusers. 

Air diffusers do exactly what their name suggests: they diffuse air. They are usually fitted on the ends of the air conditioning system’s ducts and have the role of dispersing the pumped air uniformly into the room by forcing it to pass through a blade system that spread it into small and uniform air streams. Air diffusers are passive products and require no power. 

There are multiple types of air diffusers, based on the way they diffuse the air flow. Simple one-way diffusers only guide the air flow in one direction. This type of air diffusers is commonly installed over vent covers or wall-mounted air ducts. Two-way diffusers, three-way diffusers and even four-way diffusers are also available for a more uniform spread of the pumped air and are usually used in floor or ceiling installation or in installations with a higher air output. 

Air diffusers can also be categorized by their shape or mounting location. A rectangular air diffuser is suitable to be mounted everywhere, whether it’s a wall-mounted air duct, over a floor register or ceiling duct while round air diffusers are more appropriate to ceiling mounting. A good example of rectangular diffusers is Hart & Cooley’s A500 Series of sidewall or ceiling diffusers, available in one-way, two-way, three-way or four-way construction. 

The main benefit of using air diffusers is obviously a more uniform air flow. This translates into less stress on the air conditioning system, as it doesn’t have to operate at full throttle in order to cover every corner of the room, and thus reduced costs. Another advantage of using air diffusers is that an uniform air flow will prevent drafts, hotspots and humidity. 

Some people mistake air diffusers for air grilles — a fair mistake, considering that these elements sometimes look alike. However, keep in mind that the role of a grille is to prevent objects from entering the ducts and clog them, thus they are being specifically built to be strong. Air diffusers, on the other side, are sensitive devices.
