linear diffusers and grilles Q&A

Q1: What are the long linear air vents used for?

A1: Long linear air vents are used to supply or return air in long, narrow spaces. Their extended shape fits seamlessly into architectural areas like in the ceiling, floor, or wall, providing an unobtrusive source or return of airflow.

Q2: How does a diffuser work?

A2: A diffuser works by spreading the air from the HVAC system evenly across a room. It helps to maintain a comfortable temperature and reduce hot or cold spots. The air is spread out and mixed with the air in the room to achieve this.

Q3: What is the difference between a grille and a diffuser?

A3: A grille is used to either supply or return air and does not change the direction of the airflow. A vent, on the other hand, is used to either supply or return air and changes the direction of the airflow. The two can be easily distinguished; a grille has a flat faceplate, while a diffuser has a tapered faceplate.

Q4: What are the three types of diffusers?

A4: The three types of diffusers are:

• Ceiling diffuser - This is installed on the ceiling to supply air to a room. It is used when the HVAC system is installed on the ceiling.
• Floor diffuser - This is placed on the floor and is used when the HVAC system is installed on the wall.
• Wall diffuser - This is installed on the wall and is used when the HVAC system is installed on the floor.
