Understanding Your Airflow Needs: The Foundation of Selection

The first and most critical step in how to select linear slot diffuser is to accurately determine the airflow requirements for the spaceLinear Diffusers and Grilles - Application Guidelines This typically involves understanding the CFM's that the room the Linear Slot Diffusers will be in needsLCS Linear Slot Diffusers This data is usually derived from load calculations performed during the initial HVAC equipment selection phaseThe LINED® is an aluminiumlinearadjustableslot diffuserfor use on air supply or return systems in non-residential buildings.

Key Parameters for Linear Slot Diffuser Selection

Once you have your CFM requirements, you can begin to evaluate specific linear slot diffuser modelsLinear Slot Diffusers - Bovema Several parameters come into play:

* Number of Slots: Linear slot diffusers are available with varying numbers of slots, often ranging from one to eight slotsLINEAR SLOT DIFFUSERS The number of slots you select will depend on the required airflow and noise criteriaSlot Diffusers As highlighted in guidance for models like the LCS and SD223, they "should be selected with 1,2,3,4 slots according to the air flow rate and noise criteriaSD223-Hidden Linear Slot Diffusers" Considering smaller linear slot diffusers can hinder airflow and produce noise, while larger ones might offer less resistanceLinear Diffuser Precision Airflow for Modern Spaces - SuperAir

* Slot Width and Length: The slot width and overall length of the diffuser are also vitalLDK/G | Hidden Linear Diffuser You will need to Select Outlet Type (Slot Width) by model numberModel CE - Linear Slot Diffusers The length of the air outlet, in conjunction with the number of slots, determines the total face area available for air dischargeLinear Diffusers and Grilles - Application Guidelines You should also "Select noLINED® series – aluminium - Slot diffusers of slots and the length of air outlet that give the required CFM at recommended outlet velocity from performance data tablesSlot Diffusers"

* Airflow Rate and Velocity: Performance data tables provided by manufacturers are essential resourcesI would start after load calc and equipmentselection. Figure out the approveddiffusertype from architect. Then figure out the CFM that needs to be in the  These tables will help you match your required CFM to specific diffuser configurations, considering the recommended outlet velocityManually and from theslotface opening, the air flow rate can be adjusted by moving the sliding part of the Hit - and - Miss damper left or right. For example, some guidelines suggest you can "select performance using vertical/sidewall projection nomogram and ignore throw values" for extract applications, emphasizing the importance of understanding the airflow’s trajectoryThe following pages give details onhow to correctly select the CE Slot Diffusers, together with a worked example.
