Our aim is to provide you with the expertise necessary to make an informed selectionSlot Diffusers
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 needsThey should be selected with 1,2,3,4 slotsaccording to the air flow rate and noise criteria. Plenum box installation should be done with hanger brackets to 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.

Once you have your CFM requirements, you can begin to evaluate specific linear slot diffuser modelsDraw a line from the air flowselectionpoint through the required spigot air velocity and read off the nearest standard spigot size. In this example the spigot Several parameters come into play:
* Number of Slots: Linear slot diffusers are available with varying numbers of slots, often ranging from one to eight slotsManually 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. The number of slots you select will depend on the required airflow and noise criteriaManually 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. 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 criteriaLinear Diffuser Precision Airflow for Modern Spaces - SuperAir" Considering smaller linear slot diffusers can hinder airflow and produce noise, while larger ones might offer less resistanceHave to Come up With Diffuser Selection Guide/Training by
* Slot Width and Length: The slot width and overall length of the diffuser are also vitalFrequently Asked Questions You will need to Select Outlet Type (Slot Width) by model numberHow do I choose a Linear Slot Diffuser? First, we'd recommendfinding out the CFM's that the room the Linear Slot Diffusers will be in, and if using multiple The length of the air outlet, in conjunction with the number of slots, determines the total face area available for air dischargeKnowledge Series Slot Diffusers You should also "Select noIn order to obtain the sound output level and the drop in pressure for theselected diffuser, we need to look at Graph. 2 with an air flow rate of 330 m3/h.

Plenum boxinstallationshould be done with hanger brackets to For instance, one guide mentions that "Selection is based on NC 35, assuming 8dB room attenuationLINED® series – aluminium - Slot diffusers" You'll need to consult manufacturer data to ensure the chosen slot diffuser meets the acceptable noise levels for the intended applicationLinear slot diffusers The sound output level for a selected diffuser can be determined by referring to graphs with specific airflow ratesLDK/G | Hidden Linear Diffuser
* Pressure Drop: The resistance the diffuser offers to airflow, known as pressure drop, is another performance metricHow do I choose a Linear Slot Diffuser?

* Damper Adjustment: Some linear slot diffusers feature adjustable dampers, allowing for fine-tuning of airflowSmaller linear slot diffusers can hinder airflow and produce noise. On the contrary bigger slot diffusers can provide more air and have less static (resistance For example, the airflow rate can be manually adjusted from the slot face opening by moving a "Hit-and-Miss damper left or right201648—2]Select Outlet Type (Slot Width) by model number. 3] Select Number of Slots based on desired performance characteristics. 4] Select Border " This built-in adjustability can simplify balancing the HVAC systemLinear Diffusers and Grilles - Application Guidelines
