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 baseboard register?
Baseboard floor registers are a bit different from typical registers, but replacing them isn’t difficult. With baseboard registers, the ductwork opening in the floor is long and slender — about half as wide as a standard register — and located along the edge of the wall.
What is the difference between an air diffuser or register?

What is air duct register?
Registers. Registers are the vents that control air flow into a room from heating and cooling systems. A louvered damper enables control of the air, which can be directed in at least one direction or, in some cases, up to as many as four, or diffused altogether.

Should air vents be high or low?
To ensure efficiency during the cooling season, your home should have high registers. High return registers draw hot air that rises to the ceiling back into the system to repeat the cooling cycle.
Why are vents placed under Windows?
When warm room air hits it, the air cools, and cool air sinks. The movement of cool air creates floor drafts that most people find uncomfortable. The placement of forced-air heat registers or baseboard heating units under the windows counteracts this process by sending up warm air to mix with the cool.
Do vent covers make a difference?
