The spread shown for the heating mode is for a valve setting of 22° right deflection and 22° left deflection. *The maximum
value given for spread for heating is that which occurs at the ceiling height (8 ft.). The cooling spread is a straight vertical
column of air and is not shown. Throw and spread values are based on a terminal velocity of 50 fpm.

*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.

Velocity Limitations
for Various Applications
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, face
velocities can be controlled within safe sound limits.
The following recommended face velocities are within
the safe sound limits for most applications, when NC
data are not available.

*Velocity measured 1 inch from face. Multiple readings are taken in face areas not exceeding 6” x 6”, but in no case less than 6 readings, to
ensure a representative CFM = Ak x Average Measured Velocity.

ALC Series
Curved-Blade Diffusers
Selection Procedure
ALC Series Curved-Blade Diffusers
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
ALC tables gives 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 with no
obstruction to the air stream.
3. Turn to the proper SIZE
TABLE for the air pattern
desired.
4. Determine the appropriate
size based on the CFM,
Throw, Pressure Loss, and
Face Velocity requirements.

The 290 Series grille has many applications for any heating or cooling
requirement either on ceiling or sidewall installation. You can create practically
any pattern necessary. The easy and quick individual adjustment of the
curved-blade louvers can be accomplished without removing the grilles from
the wall or ceiling. Ideal for overhead duct systems where air conditioning
is being installed. Correct the air pattern problem in remodeling installations
where air outlets are located at baseboard; direct the air where it is most
desirable.

Notes:
1.Ps is static Pressure Loss in inches of H2O.
2. NC is based on 10dB room attenuation (RE: 10-12 watts).
3. Throw is isothermal air at 150, 100, 75 FPM terminal velocities.
4. The use of a balancing hood is recommended to balance the system.

Tests conducted in accordance with ANSI/ASHRAE 70-1991 at isothermal conditions.
Tests conducted with a straight rigid inlet condition. Other inlet conditions may alter performance.
Unit of measure: Neck Velocity = FPM; Velocity Pressure = in. w.c.; Airflow Rate = CFM; Total Pressure = in. w.c.;
Throw = ft at 50, 100, and 150 FPM terminal velocity
Noise Criteria (NC) is based upon 10dB room absorption (Re: 10-12 watts) evaluated at 125 thru 4000 Hz octave
Flow hoods are recommended for system balancing.
Two-Way
(Short Throw)
• For throw in both
directions, use
short throw data.
One-Way
(Long Throw)
• For throw, use
long throw data.
Models 1274, 12P, 12PFF
Return Air Grille Balancing Data
Neck Area
The cross-sectional area (sq. ft.) of the duct at the point where the
diffuser is attached, all dimensions are nominal.
Neck Velocity
Airflow Rate (CFM) divided by Neck Area (sq. ft.) equals Neck
Velocity (FPM).
Sample Problem
Determine Return Airflow Rate (CFM) through a 10 x 10, using an
ALNOR Velometer with Tip No. 2220 or 2220A.
Static Pressure
Static Pressure Drop is given in inches of W.G.
To Determine CFM:
1. Use an ALNOR Velometer with No. 2220 or 2220A Tip or a 4”
rotating vane anemometer. If a 4” rotating vane anemometer is
used, place dial face against perforated plate, and sample in a
random manner for at least 1 minute.

Solution
1. Assume the average of 6 velocity readings taken with an
ALNOR Velometer is 2000 FPM.
2. From Table, the Area Factor for a 10 x 10 using an ALNOR
Velometer is Ak = .39 sq. ft.
3. CFM = Ak x Average Velocity = .39 sq. ft. x 2000 FPM = 780

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

Note: Tested without filters. Typical capacity is 2 CFM per
square inch of nominal filter area. Recommended face
velocity is 300-450 FPM. Velocities higher will decrease filter
performance, increase flow resistance, and possibly be of
noise concern. Velocity measured 1" from face.

Notes:
1.Table 1 based on 4-foot diffuser length. For longer lengths, correct throw
and NC per Table 2.
2.For 2-way ceiling throw, proportion CFM and number of slots in each
direction of T, and select from 1-way data, Table 1.
3.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.
4.Ps constant for horizontal 1-way, 2-way and vertical pattern adjustment.
5.Supply air temperature effect on horizontal throw is shown in Table 3.
Vertical throw at varying supply air temperatures is shown in Table 4.
6.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.

5. 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
6. 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.

Notes:
1. All pressures are in inches of water.
2. Neg. SP is negative static pressure.
3. NC values are based on room absorption of 10 db., re 10-12 watts.
4. Bold dividing lines denote ranges of NC values.

*Face Velocity and Effective Area based on 4” Rotating Vane Anemometer.
To
1)
2)
3)
determine CFM using this table:
Under “aluminum” or “steel” find the Effective Area of the grille.
Using a 4” Rotating Vane Anemometer, measure the velocity on the intake side of the grille.
Determine CFM by the following equation: CFM = Effective Area x Measured Face Velocity.
