The difference is that VAV diffusers have a [built-in VAV damper](https://blog.priceindustries.com/how-do-vav-diffusers-work) and can close to a minimum, possibly building up pressure in the system. It is the higher pressure that makes diffusers noisy, and because of this, a method of pressure control should be used in every VAV diffuser system.

Controlling the direction of this “transfer air” helps to prevent the migration of unwanted particles, which can directly impact occupants and products in or near such spaces.
