Grilles, registers and diffusers cover supply or return openings for HVAC systems. These devices can be for aesthetic or functional (direction and control) purposes with a wide variation in type, features and mounting locations. Grilles and registers are for use in a wide variety of commercial, industrial and institutional installations.
What are grilles used for?
A grille is a vent cover through which air is blown into or out of a room for circulation back to the central heating or cooling unit. These are commonly found if you have heating or central air conditioning. A grille has no damper to control air flow, so air is left to flow freely.
What is the difference between diffuser and grilles?
A special device used in supplying and extracting air vertically without any kind of deflection is called a grille. A device used to direct the air at different angles by profiled blades when the air is leaving the unit and going into the space is known as a diffuser.
What is a diffuser in HVAC?
In HVAC systems, the air supply diffuser is a device that delivers and ventilates conditioned air in an area, mixes indoor air, and manages air output. It works by reducing the air duct velocity by increasing the static pressure. << Return to Glossary.
What are diffusers in construction?
Rooftop air diffusers are used to bring conditioned air into a building from an HVAC unit and then return air back to the rooftop. Diffusers are an excellent delivery system for air and an alternative to a complex duct system.
Is a grille necessary?
While the look of a grille is certainly vitally important for customer satisfaction, each grille also plays a very important role in cooling the vehicle's engine, specifically the radiator. Without some way for air to flow into the engine compartment, a car would pose a major risk of overheating.

Different essential oils have different claims—for example, lavender is meant to support sleep.
What is the main function of diffuser?
The diffuser is an important element of a compressor or pump. Its purpose is to reduce the velocity of the flow leaving the impeller resulting in an increase in pressure. The diffuser can be simply depicted as a nonrotating channel whose flow area increases in the direction of flow (Figure 7.7). Figure 7.7.
What is the difference between a vent and diffuser?
There is no difference between Vents, Diffusers, Registers, Grilles. They are all just different names used by different industries for AC Vent Covers. AC Vent Covers are the "Face" of your AC Ducts which is the inside of the black box you see when you remove your AC Vent Covers.

Given these four choices, how do you decide which one would work best for you?
What is the difference between grilles and registers?
