Slot Diffusers
Damper
Single leaf dampers are furnished in each slot opening throughout the entire
diffuser length when specified. Dampers are fastened to the margin and are
spring loaded to hold their setting at all duct pressures. They are face operated
with a removable operator. Multiple dampers are furnished for grille lengths over
24 inches.
Dampers are part of the S Series and are not specified separately.
Frames
Plaster frames are available to provide a positive dimensioned ceiling or wall
opening for the diffuser or grille.
Frames for S series diffusers are furnished with formed bridge spacers to
maintain a uniform rigid opening during installation. The duct collar is fastened to
the frame. After plastering, the spacers are easily removed and the diffuser is
installed from the room side.
See specific S Series for frame dimensions and installation details.
No. 2
90-degree mitered corners are available as factory fabricated sections. Precise
factory cutting and assembly reduces field fabrication time and assures proper
fit. Mitered corner sections are furnished in one piece with pattern deflectors and
dampers in the dimensions as indicated. Corner sections butt to adjacent straight
sections which are spliced together with aligning keys.
Mitered corners are furnished in style #4 (with pattern controller and damper).
When viewed from the room side, the mitered corner section appears identical to
the butting straight sections.
Plaster frame mitered corners can be specified with the outlet mitered corner.

Engineering Data
The Terminal Velocity is listed for each chart since it has such a dramatic effect on the listed throws.
Method of Measurement:
I Supply:
Position the probe flush to the diffuser or register face bars and centered in the opening. Multiple
readings should be taken in face areas not to exceed 6" x 6" but in no case less than six (6)
readings to ensure a representative average. This average velocity in FPM is used in the equation:
CFM = A k x Vave. (where Ak=Effective Area and Vave=Average Face Velocity). See Fig. 1.

AIR MEASUREMENT — RETURN

FIG.1
FIG. 2
Using the Engineering Data
For a given CFM and chosen register style and location(s), use the chart to select a size that delivers the
required CFM at a velocity that is recommended for the particular application or throw requirement. Noise
increases with increasing velocities. If CFM is constant, an increase in either register size or the number
of registers of a given size will decrease the velocity, throw, and related noise.
No single type of supply register provides optimum air distribution for yearround air conditioning since the
preferred outlet for one season will be a compromise for the other season. However, the success of an air
diffusion system is dependent almost entirely on the location of the supply diffusers. The location of return
grilles is far less critical. Return airflow affects room air motion only in the immediate vicinity of a return
air grille.
Introduction to Engineering Data
II Return:
The position of the thermoanenometer probe must be held at a distance of 1" from the face of the
grille for prime accuracy. This is critical and should not vary by +_ 1/32". A position gauge can be
attached to the probe for this purpose. Multiple readings as described above are required. See Fig. 2.
As a general rule, maximum recommended face velocity for a supply outlet used in a residential
application is 800 FPM. Maximum recommended return grille velocity is 400 FPM. Systems with higher
velocities are likely to have noise problems.
Return air filter grille velocities greater than about 400 FPM will exceed the performance of the filter.
Note: For sizes not listed, use nearest Total Square Inches.

*Tested without filters. Typical disposable 1-inch capacity is 2 cfm per square inch
of gross filter area. Recommended velocity is 300-400 fpm. Velocities higher than
500 fpm will decrease filter performance. Increase flow resistance, and possibly
blow off agglomerates of collected dirt. Velocity measured 1” from face.

*Tested without filters. Typical disposable 1-inch capacity is 2 cfm per square inch
of gross filter area. Recommended velocity is 300-400 fpm. Velocities higher than
500 fpm will decrease filter performance. Increase flow resistance, and possibly
blow off agglomerates of collected dirt. Velocity measured 1” from face.

C Series Curved-Blade Diffusers
Selection Procedure
C Series Curved-Blade
Diffusers (Page 47-51)
One-Way, Two-Way
1. Determine the diffuser air pattern best suited to the duct layout and room
area to be served.
2. Select the air pattern type and CFM per outlet. The tables give the
recommended limits of air volume per outlet for various ceiling heights.
Choose the correct table for the style diffuser selected. Outlets are assumed
to be mounted flush on the ceiling and no obstruction to the air stream.
3. Turn to the proper SIZE SELECTION TABLE for the air pattern desired.
4. Determine the appropriate size based on the CFM, Throw, Pressure Loss,
and Face Velocity requirements.

Tests conducted in accordance with ANSI/ASHRAE 70-1991 at isothermal conditions.
Engineering Units:
Airflow rate = cfm/linear foot
Static Pressure = in. w.c.
Throw = ft at 50, 100, and 150 fpm terminal velocity
Noise Criteria is based on 10 dB room absorption (Re: 1012 watts) evaluated at 125 through 4000 Hz octave bands.
Throw data are based on a horizontal discharge in one direction only. For 2-way discharge pattern, the throw is determined from the published engineering data based on the number of slots
and cfm/lin ft discharging in each direction.
Throw data are for 4-foot active diffuser lengths. For other active lengths, throw
may be determined by applying the following multiplication factors.

L Series (Page 70-72)
NOTES:
a. Table 1 based on 4-foot grille length. For longer lengths, correct throw and
NC per table 2.
b. When using continuous grille lengths with alternate active and inactive sections, a
reduction in throw can be obtained by omitting the factors contained in Table 2.
c. Bar style 30 and 01
Increase Table 1 NC + 5 NC
d. Supply air temperature effect on horizontal throw is shown in Table 3. vertical downthrow at varying supply temperatures is shown in Table 4.
e. When spreading the air path with a horizontal deflection of 22º per side in grille lengths
up to 4 feet:
Multiply Table 1 Throw x .75
Increase Table 1 NC + 5 NC
Multiply Table 1 Ps x 1.20
Multiply Table 5 Ak x .90
f. Terminal velocities (Vt) at the minimum and maximum throw (T) values are rated at
125 fpm and 75 fpm respectively with corresponding room velocities (Vr) of 50 fpm
and 35 fpm.

TYPE 50 SUPPLY DIFFUSER AREAS Per Foot of Length
NOTES:
a. Table 1 based on 4-foot diffuser length. For longer lengths, correct
throw and NC per Table 2.
b. For 2-way ceiling throw, proportion cfm and number of slots in
each direction of T and select from 1-way data, Table 1.
c. When using continuous diffuser lengths with alternate active and
inactive sections, a reduction in throw can be obtained by omitting
the factors contained in Table 2.
d. Ps constant for horizontal 1-way, 2-way and vertical pattern
adjustment.
e. Supply air temperature effect on horizontal throw is shown in Table
3. Vertical throw at varying supply air temperatures is shown in
Table 4.
f. Terminal velocities (Vt) at the minimum and maximum throw (T)
positions are rated at 150 fpm and 100 fpm respectively with
corresponding room velocities (Vr) of 50 fpm and 35 fpm.

* Tested without filters. Typical disposable 1 inch filter capacity is 2 CFM per square inch of gross filter area.
Recommended velocity is 300-400 FPM. Velocities higher than 500 FPM will decrease filter performance, increase
flow resistance, and possibly blow off agglomerates of collected dirt. Velocity measured 1" from face.

The sound caused by an air outlet in operation is directly proportional to the
velocity of the air passing through it. By selecting outlets of proper sizes, air
velocities can be controlled within safe sound limits.
The following recommended outlet velocities are within the safe sound limits for

Instructions for use
of Drop Chart
The drop of the air stream is determined
by using the throw and velocity of the
register selected. On the drop chart, lay a
straight edge connecting these values. The
total drop of the air stream will be the sum
of the drop due to temperature (Dt) and
the drop due to spread (Ds).
160
Example: The drop for a 92 Series register
“C” deflection 16x5 size has an 800 fpm
velocity and a 16 foot throw. Connect these
two points on the chart and read the drops
as follows:
Dt = 2.7'
Ds = 2'
D total = 2.7 + 2 = 4.7'
Dt = Drop along line of throw
due to temperature difference.
Ds = Drop resulting from
vertical spread.

Grille Width
in Inches
Method of Determining
Alternate Grille Sizes
Extensive tests indicate that by varying dimensions of a grille
there is no appreciable effect on the air throw, provided the
same area is maintained. To change the dimensions of a
grille, place a straight edge across the width and height
scales on dimensions as selected from charts. Place a pointer
at the crossing point on the turning line and rotate the
straight edge around this point until it crosses width and
height scale at dimensions desired.

General Conclusions on
Air Distribution
1. The throw from a straight flow grille varies with the square
root of the daylight area of the grille and with the face
velocity.
2. The ratio of the width to the height (aspect ratio) of a
grille has no appreciable effect on the distance of air
throw.
3. If the air streams from a grille are converged, it results
only in cutting down the effective area of the grille.
4. Breaking the air stream up into jets has no effect on either
the rate of mixing or the flow.
5. Fanning out the air stream shortens the throw, the amount
depending on the degree of deflection.
6. The drop, for a given throw, of an air stream below room
temperature varies about inversely as the face velocity and
directly as the temperature differential.
7. For any given velocity neither the aspect ratio of the grille,
breaking the air stream up into jets, nor impinging the air
streams together equally have any effect on the drop of
the air stream.

Glossary of Terms
Radius of Diffusion, Ft.
The horizontal distance (throw) from a ceiling diffuser to the point of terminal
velocity.
Register
A grille which is equipped with a damper or control valve, and which directs air in
a nonspreading jet.
Return
Any opening through which air is removed from a conditioned space.
Spread, Ft.
The maximum width of the total air stream at the point of terminal velocity.
Static Pressure, PS
The outward force of air within a duct measured in inches of water.
Stratification Boundary
The boundary between room air currents moving faster than 1 5 fpm and the
stratification zone.
Stratified Zone
A region in which room air velocity is less than 1 5 fpm.
Temperature Difterential
The temperature difference between the primary and the room air.
Temperature Variation (∆T)
The temperature difference between points within the same space.
Terminal Velocity, Fpm
When the velocity of total air drops to 50 or 75 fpm, depending on the particular
application, it reaches terminal velocity. Terminal velocity is not sharply defined
for all applications.
Throw (Blow), Ft.
The horizontal distance an air stream travels after leaving a horizontal sidewall
outlet before maximum velocity is reduced to terminal velocity. For a perimeter
outlet, throw is the vertical distance the air stream travels before maximum
velocity is reduced to terminal velocity.
Total Air
The mixture of projected air and room air set in motion by the supply air.
Total Pressure, Pt
The sum of the velocity and static pressures measured in inches of water.
Vane Ratio
The ratio showing depth of vane to minimum width between two adjacent vanes.
Velocity Pressure, Pv
The forward-moving force of air within a duct measured in inches of water.
NC Noise Criteria
A single number noise rating system that indicates what Broad Band, continuous
sounds are reasonably acceptable.
Engineering Data
Ceiling or Wall Effect
The tendency of an air stream moving along a wall or ceiling surface to remain in
contact with that surface.
Core Area
The total plane area of that portion of a grille, face, or register bounded by a line
tangent to the outer opening through which air can pass. The core area is less
than the register size. Example, a 14-in. x 8-in. register may have a core that is 1
in. less than the listed size; so, the core area is 13in. x 7in. – 91 sq. in.
Diffuser
An outlet discharging supply air in a spreading pattern.
Diffusion
Distribution of air within a space by an outlet discharging supply air in a
spreading pattern.
Drop
The vertical distance between the base of the outlet and the bottom of the air
stream at the end of the horizontal throw.
Effective Area, Ak (Sq. Ft.)
The calculated area of an outlet based on the average measured velocity between
the fins.
Envelope
The outer boundary of an air stream moving at a specific velocity (for example, a
50 fpm envelope).
Free Area
The total minimum area of the openings in the air outlet or inlet through which
air can pass.
Grille
A louvered covering for an opening through which air passes.
Induction
The process of drawing room air into the projected air stream due to the velocity
of the projected air stream (sometimes called aspiration).
Jet Velocity, Fpm (Face Velocity)
The average measured velocity of air passing between the fins.
Natural Convection Currents
Air currents created by a buoyancy effect caused by the difference in
temperature between the room air and the air in contact with a warm or cold
surface.
Outlet
Any opening through which air is delivered to condition a space.
Outlet Velocity, Fpm
The average velocity of the supply air, measured as it passes through the plane of
the opening in the supply outlet.
Pressure Loss, WG
Indicates how much total pressure is required to move air through a register.
Primary Air
The mixture of supply air from the outlet and room air within the 1 50 fpm
envelope.
