The first and most critical step in how to select linear slot diffuser is to accurately determine the airflow requirements for the spaceThe following pages give details onhow to correctly select the CE Slot Diffusers, together with a worked example. Please read the notes carefully and contact This typically involves understanding the CFM's that the room the Linear Slot Diffusers will be in needsLINED® series – aluminium - Slot diffusers This data is usually derived from load calculations performed during the initial HVAC equipment selection phaseLinear Diffuser Precision Airflow for Modern Spaces - SuperAir Knowing the required CFM will guide you in choosing a diffuser that can deliver the necessary air volume without compromising performance or comfortLinear slot diffusers
Once you have your CFM requirements, you can begin to evaluate specific linear slot diffuser modelsSmaller linear slot diffusers can hinder airflow and produce noise. On the contrary bigger slot diffusers can provide more air and have less static (resistance 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, commonly known asSlot Diffusers, have been in use for a long time. This article discusses the various design and functional aspects The number of slots you select will depend on the required airflow and noise criteriaThe following pages give details onhow to correctly select the CE Slot Diffusers, together with a worked example. Please read the notes carefully and contact 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 criteriaSupply grilles,lineargrilles, transit grills, return grilles, exterior air intake grilles, ceilingdiffusers, long range nozzles,lineardiffusers." Considering smaller linear slot diffusers can hinder airflow and produce noise, while larger ones might offer less resistanceSmaller linear slot diffusers can hinder airflow and produce noise. On the contrary bigger slot diffusers can provide more air and have less static (resistance
* Slot Width and Length: The slot width and overall length of the diffuser are also vitalConstructed of extruded aluminium, thesediffuserscan be used in virtually any type of ceiling. Available in 3 differentslotwidths, from 1 through 8slots, You will need to Select Outlet Type (Slot Width) by model numberSlot Linear Diffuser The length of the air outlet, in conjunction with the number of slots, determines the total face area available for air dischargeLCS Linear Slot Diffusers You should also "Select noSelectionis based on NC 35, assuming 8dB room attenuation.

* Airflow Rate and Velocity: Performance data tables provided by manufacturers are essential resourcesLDK/G | Hidden Linear Diffuser These tables will help you match your required CFM to specific diffuser configurations, considering the recommended outlet velocityLinear Diffusers - Madel 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 trajectoryLINED® series – aluminium - Slot diffusers
* Sound Levels (NC Criteria): Noise is a significant factor in occupant comfortLinear Diffusers and Grilles - Application Guidelines Linear slot diffusers are often selected based on noise criteria (NC)LINED® series – aluminium - Slot diffusers For instance, one guide mentions that "Selection is based on NC 35, assuming 8dB room attenuationCHAPTER-3-LINEAR-SLOT-DIFFUSERS.pdf" You'll need to consult manufacturer data to ensure the chosen slot diffuser meets the acceptable noise levels for the intended application3.Select no. of slots and the length of air outletthat give the required CFM at recommended outlet velocity from performance data tables.

In this example the spigot
* Pressure Drop: The resistance the diffuser offers to airflow, known as pressure drop, is another performance metricLinear Slot Diffusers While not always the primary selection driver, it can impact fan energy consumption and overall system efficiencyLINED® series – aluminium - Slot diffusers
Beyond the fundamental parameters, several other aspects warrant attention:

On the contrary bigger slot diffusers can provide more air and have less static (resistance
* Damper Adjustment: Some linear slot diffusers feature adjustable dampers, allowing for fine-tuning of airflowModel CE - Linear Slot Diffusers For example, the airflow rate can be manually adjusted from the slot face opening by moving a "Hit-and-Miss damper left or rightSlot Diffusers" This built-in adjustability can simplify balancing the HVAC systemSupply grilles,lineargrilles, transit grills, return grilles, exterior air intake grilles, ceilingdiffusers, long range nozzles,lineardiffusers.
