Supply Air Diffuser Cfm

A circular ceiling diffuser such as our 16 is one possible.

Supply air diffuser cfm.

Perpendicular air flows nominal airflow. Supply air diffusers return air diffuser never do this. However the cfm ranges between 2 0 and 3 5 m s. Use the calculator below to quickly and easily determine the grille airflow.

Using this as a given the lowest airflow rate. The location is a ceiling and a circular or 4 way pattern is required. Air flow calculator linear bar grilles. Inches please fill in either cfm cubic feet per minute value or fpm feet per minute value.

If one enters the chart at 1 cfm ft2 5 l s per m2 as is a typical interior air design airflow rate one can see that the optimum half diffuser spacing would be about 10 ft at 350 cfm 3 m at 165 vs. Registers premium stamped supply and bar type supply registers with a pristine white powder coat finish. These linear slot diffusers feature fully adjustable aerodynamic pattern controllers fabricated from extruded aluminum and are available in a large selection of frame styles.

Figure i shows the performance of such a diffuser. The uniform nearly horizontal jet from the outer cone maintains effective room air distribution even when the air volume varies over a considerable range. The sds linear slot diffuser is designed to satisfy architectural applications that require continuous lengths without compromising air distribution performance. Diffusers some of the best high capacity diffusers on the market with different options for each.

Ceiling diffuser for this initial discussion of sizing a supply register or diffuser we will narrow the selection criteria to only cfm face velocity and throw which will minimize unnecessary complications. The acceptable cfm airflow from the supply air diffuser depends on the throw and the noise of the supply air diffuser. Combination supply return plenum slot diffuser 3 4 slot fixed blade slot with down blow section 2 return slot tbdi 80 adjustable gasket tipped blade plenum slot diffuser. The tms is a square ceiling diffuser that delivers supply air in a true 360º pattern with low pressure drop.
