[′er di‚fyüz·ər] (building construction) An air distribution outlet, usually located in the ceiling and consisting of deflecting vanes discharging supply air in various directions and planes, and arranged to promote mixing of the supplied air with the air already in the room.
What is the role of a 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).
What is a diffuser in ventilation?
A ventilation diffuser disperses pressurised air exiting heating ventilation and air conditioning ductwork and provide a decorative finish over the grill box hole holding the ductwork in place. Without an air diffuser, the air exiting the HVAC system would travel in a straight direction.
How does a slot diffuser work?
A slot diffuser sits at the duct terminal in each room and allows heated or cooled air to enter the space. Each slot diffuser features a linear plenum, or box that fits above the ceiling. This plenum space helps to improve air flow, and allows air to enter the space at an even, steady pace.

When would you use a linear slot diffuser?
The reasons for this is simple: Linear diffusers offer a minimal and clean look. They take up less space and can be used on ceilings or walls. Linear diffusers can be used as an “air curtain” next to doors, large windows and entrances.Feb 7, 2020

What is the difference between grilles and diffusers?
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.Mar 9, 2017
What does a vent diffuser do?
Vent diffusers disperse pressurized air exiting heating ventilation and air conditioning (HVAC) ductwork and provide a decorative finish over the grill box hole holding the ductwork in place. Without an air diffuser, the air exiting the HVAC system would travel in a straight direction. ... A ceiling vent diffuser.
What are grilles used for?
A grille or grill (French word from Latin craticula, small grill) is an opening of several slits side-by-side in a wall, metal sheet or another barrier, usually to allow air or water to enter and/or leave and prevent larger objects (such as animals) from going in or out.
What's the difference between a grille and a register?
Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. Louvres, or dampers, are often attached to the back of a heat register. ... A grille has no damper to control air flow, so air is left to flow freely. Grilles do not have the damper normally found on registers.Apr 9, 2014
What is supply diffuser?
What is a Supply Air Diffuser? A supply air diffuser is a diffuser found in a ventilation system whose function is to allow for the flow of airflow of airAirflow, or air flow, is the movement of air. ... Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.https://en.wikipedia.org › wiki › AirflowAirflow - Wikipedia from the outside into the room. This is by allowing air to flow out of the ventilation system into the room.

What does a ceiling supply diffuser do?
A ceiling air diffuser is a channeled cover placed over an air conditioning distribution duct in the ceiling of a room. The channels or slots in the diffuser direct air to flow in specific directions, thereby allowing cool air to go exactly where it is needed.
