Diffuser and Plenum Box Properties

Property Name	Description
Air Flow Rate (CFM) Air Flow Rate Unit	`Positive <numeric value>` Sets a value for the amount of flow through Diffuser. Used to calculate overall flow rate during analysis operations. Air Rate Unit sets the air flow rate in cubic units per minute. This property is used by the Analysis tool for calculating upstream air flow rates for connected elements. Diffuser/plenum fittings when used as route openings in the duct sizing, takes the air flow value for calculation.
Auto Size	Mesh: h `<numeric value>` Sets horizontal spacings of the mesh. v `<numeric value>` Sets vertical spacings of the mesh. 4way: nh `<numeric value>` Sets number of horizontal slots of 4way grille. nv `<numeric value>` Sets number of vertical slots of 4way grille. t `<numeric value>` Sets thickness of the slots. others: n `<numeric value>` Sets number of slots. t `<numeric value>` Sets thickness of the slots. Grille Type Sets type of grille to— Bars— BarSlots— Star— RectSlots— RndSlots Each option is separated with a delimiter / . Example: mesh:h=4;v=4/4way:nh=5;nv=5;t=0.5/others:n=5;t=0.5 Note: updating values in the string option for the current Grille Type reflects the changes in the diffuser grille.

Box \| Top Width	`Positive <numeric value>` Sets top width of diffuser box.
Box \| Width	`Positive <numeric value>` Sets bottom width of diffuser/plenum box.
Columns	`<integer>` Sets number of columns of Jet Nozzles on the Panel of Jet Diffuser.
Connection 1 \| Length (L1)	`Positive <numeric value>` Sets straight length at End1 for Jet Diffuser.
Connection \| On Left Side	1-Yes 2-No Sets or no additional port at left side of plenum box at End6.
Connection \| On Right Side	1-Yes 2-No Sets or no additional port at right side of plenum box at End7.
Connection \| End Type	fl `-<numeric value>` Sets and sizes end with a flange connection. m `-<numeric value>` Sets and sizes end with a male connection. fe `-<numeric value>` Sets and sizes end with a female connection. Separate End Type entries for each End Spec with a semi colon. Example: fl-2; creates a flange at End1 with size 2, and fe-.13; creates a female connection at End1 with an overall reduction of component's dimensions of .13
Connection \| Length	`Positive <numeric value>` Sets length of straight portion at connection.
Connection \| Side	1-top Puts connection on top of diffuser box. 2-side Puts connection on side of diffuser box.
Duct Connecting Length	`Positive <numeric value>` Sets straight length at End2 for Plenum box.
Equipment Connecting Length	`Positive <numeric value>` Sets straight length at End1 for Plenum box.
Flange \| Size	`Positive <numeric value>` Sets the flange dimension, exterior to Jet body.
Grille \| Depth	`Positive <numeric value>` Sets depth of grille portion.
Grille \| Diameter	`Positive <numeric value>` Sets the diameter of grille portion.
Grille \| Thickness	`Positive <numeric value>` Sets thickness of grille portion.
Grille \| Type	1-mesh 2-bars 3-barSlots 4-4Way 5-star 6-rectSlots 7-rndSlots Sets overall grille configuration. Grille Type selected here overrides the one set in Auto Size dialog.
Grille \|Width	`Positive <numeric value>` Sets width of grille portion.
