This is determined by assuming a 10dB (ref: 10-12 watts) room attenuation that is subtracted from the power levels in each of the 2nd thru 7th octave bands
Vertical Projection • The numbers shown in table are projection distances, in meters, measured along the jet trajectory axis relating to a terminal velocity of 0.25m/s, for a 1.2m active length. H based on a heating differential of 12° C. C based on a cooling differential of 12° C. For other active lengths, use the following projection adjustment factors:
• NC shown is based on 1.2m diffuser length. For other active lengths, use the following adjustment factors: Terminal velocity is the air speed, in meter per second, measured in the supply air stream. Pressure Ps represents Static Pressure, Pa Throw • For ceiling installed KSLAD, large numbers of slots in a single direction should be carefully studied for drop effects.
Model KRLAD Return Data Sound and pressure data shown for return unit without internal components.
• The numbers shown in table are throw distances in meter, measured along the jet trajectory axis relating to terminal velocities of 0.75m/s, 0.5m/s, & 0.25m/s, with the jet attached to a surface for a 3m+ active length. These are ONE way patterns. For other active lengths, use the following throw adjustment factors:
• For two way applications, determine proportion of air in each direction and refer to throw distance for number of slots in the same direction. Terminal velocity is the air speed, in meter per second, measured in the supply air stream High Sidewall Applications KSLAD diffuser when used in a high sidewall the air can be: • Projected vertically up the side wall to the ceiling. In this case use the horizontal pattern data, subtracting the KSLAD to ceiling distance from the throw distance given. This is the preferred method. • Directed horizontally and attaches itself to the ceiling via the Coanda effect. In this case, use the vertical projection throw (average of heating and cooling value) times 1.4 when the KSLAD is located close to the ceiling. Decrease the factor 1.4 by .1 (down to a minimum of 1.0) for every 300mm the KSLAD is located below the ceiling. The drop effect must also be studied closely when cooling is used in conjunction with this high sidewall KSLAD mounted more than 300mm – 600mm below the ceiling.

XNSA Grilles
Door Grilles Introduction KMC air transfer Grilles or Door grilles are typically used in doors and partitions to allow air flow to a space that is not directly served by a ducted source of supply air or a ducted outlet for return or exhaust air. These Door / Wall Grilles offers the largest free area possible with a completely sight proof or light proof core. The inverted – vee louver cross section not only blocks vision, but also provides stiffness. Being mounted in the lower portion of a door, a door grille is by nature subjected to knocks and bumps. Durability of KMC louvers assures good looks even after long service.
Application • The door/wall Grille XNSA is suitable for transfer of air from one room into the other. • The Grille can be either mounted to the wall or the door. • The horizontal V shape vanes are not adjustable and are sight proof • Supplies straight 0° jet air patterns for extremely long throw requirements and diffused air patterns up to 30° spread for installations which require shorter throws and greater air diffusion patterns • Vertical direction is adjustable from 0° to ±30°
Product Features • All grilles are provided with a seal on the back of the frame in order that the perimeter in contact is airtight. • Free Area 60%
Options • Frame & Blades from high quality extruded aluminum profiles – Alloy 6063/T6 • 37mm Frame & Flange width • Blades are inverted “V” horizontal cross section louvers arranged to overlap each other • The frame of the transfer Grille consists of two parts, one fixed, (holding the core) while the other part is of the sliding type which is then fixed to the other side of the partition (or door) • Available in a wide variety of sizes from 200mm x 200mm up to 600mm x 600mm • Other sizes available on request
Selection Procedure The selections can be made by means of a straight read-off from the “Performance Data” for the selected Model. • Determine the Air flow rate per outlet.

Louvers Sand Trap Louvers Introduction KMC sand trap louvers are specifically designed to allow air flow into buildings and at the same time restrict the entry of dust and sand particles where these elements are natural hazards. Manufactured from Galvanized steel material, the units are designed and tested to withstand the most severe weather conditions for many years. Installed vertically in buildings these units provide a unique feature visually but perform an important element in ventilation design.
Application The Sand Trap Louvers Model KSTL are designed for usage in serving as a Pre - Filter element in dusty conditions. It has a degree of separation of sand and large dust particles, even in cases of high dust concentrations. The vertically arranged sections and holes for sand drainage ensure the sand trap louver is self- cleaning and maintenance free. The sand trap louver is designed to separate large particles at low air velocities, thus avoiding excessive dust loading on conventional plant filters. It is not intended as a substitute for conventional supply air filtration plant. The sand trap Louver blades are formed in U Profiles placed alternately in vertical configuration.
Standard Construction • Frame: 1.2mm thick formed Aluminum, -80mm deep • Blades: 1.2mm thick extruded or Formed Aluminum • Finish: Natural Aluminum
Standard Construction • Formed construction from 2.0mm thick frame & blade thickness • Formed Aluminum Construction • Formed GI construction • Formed SS construction (consult factory) • Variety of Bird & Insect screens • Variety of finishes – powder coated to standard RAL colors
Dimensions
1800 1800
Selection Procedure The proper selection of Louver depends on following three basic criteria: • Louver Free Area • Water penetration • Resistance to Air flow
Product Selection Check List • Select Unit size based on desired performance characteristics. • Select Finish.
Please refer the selection example shown in the catalogue.

Pressure Drop For normal operation conditions Sand Trap Louver selection: Selection basis
: The sand Trap louvers should be rated for a face velocity of approx. 1.0 m/s (200 fpm)
Example
: Volume Flow rate = 1m3 /s (3600 m3/h)
Allowable Pr. Drop = 25 Pa (0.1 “ w.g). Selection
: Free Area velocity from Graph – I @ 25 Pa = 2.0 m/s.
Free Area Required = Volume Flow rate / Free Area Velocity = 0.5 m2. The size selected from the free area Table, 1200 (W) x 1200 (H). Free Area = 0.51 m2. Face Area = 1.44 m2. Face Velocity = Volume flow rate Face Area
=
1(m3/s) 1.44 (m2)
= 0.69m/s
Since the actual Face velocity (0.69m/s) is not exceeding the recommended (1.0 m/s) value, the above selection is “OK” Free Area (Sq. Mt.)
Designs should provide a reasonable safety factor for louver performance by selecting at some point below pressure drop or sand removal requirements

AIR TERMINALS
KSQ
Air Terminal KSQ Terminal Flexibility KSQ terminals are available in a wide array of control packages using pneumatic, electronic analog or factory-installed direct digital (DDC) controls. Foil-faced insulation is provided as standard. Fabric Cloth Liner insulation with the edges sealed with either tape or sheet metal (Fibre-Lok) is available. Closed cell (fiber-less) insulation and double wall construction using a full metal liner is also available. KSQ units can be provided with an integral sound attenuator for ultra-quiet performance. Low temperature unit construction is also available using 25mm thick matte-faced insulation and isolation of the air valve from the outer casing. Numerous other optional features are available including single or double cam lock access doors.
Performance The lack of intruding fasteners, tabs or other obstructions in the air stream results in very quiet sound performance and low internal pressure losses. All units incorporate full 90° rotation round dampers (except the size 600 x 400) for precise control of the airflow. All units are available with pressure independent controls for precise control of the airflow. All units with these controls are factory calibrated for minimum and maximum airflow settings prior to shipment and are easily field adjusted.
FloXact-X ™ Air Velocity Sensor • The unique shape, (patent pending) creates a linear amplified signal (at least 2.5x Pdyn) with a low noise level and pressure drop. • Extruded aluminum profile measurement. • Multi point averaging • Measurement according to “Log Tchebycheff” method. • 2% Accuracy • Strengthen measurement signal with at least 2.5x. • Accurate measurement from 1.5m/s air velocity. • Rounded apertures make FloXact™ insensitive to skew or turbulent inflow to 30° in all directions relative to the profile axis. • The units can be supplied with factorysetting with the calibrated analog or digital controllers.
FloXact sensor in primary air Inlet
Ease of Installation and Reliability KSQ terminals are compact and utilize inlet collars over 125mm in length to allow easy attachment of rigid or flexible duct. The airflow sensor is recessed over 50mm into the air valve providing protection from damage. The discharge end of the terminal has slip and drive connections for easy attachment of downstream duct work. KMC’s KSQ Single Duct terminals are constructed with zinc-coated steel for long life. The unit casings are assembled with a mechanical lock construction that insures a tight seam to minimize air leakage. Casings are internally lined with a wide variety of insulation and treatment options that conform to NFPA and UL requirements. The leaving edge of the insulation is protected from erosion by return bends on the discharge end of the unit casing. The damper blade is made of gasket material sandwiched between two round steel plates. The round damper blade in the air valve is affixed to the shaft using through-the-shaft machine applied rivets. The diecast metal shaft rotates in self-lubricating bearings for easy turning and long operating life. The damper’s flexible gasket seats tightly on the cylinder’s internal bead for tight closure.

Notes 1. Minimum and maximum values shown are Cu.Mtr / H (CMH ) & Cu.Ft. /min. (CFM) 2. Minimum and maximum airflow with pressure independent controls based on the following. Flow sensor signal : Direct Digital Controllers : 8 Pa (0.03” WG ) - 190 Pa (0.76” WG) 3. Settings below the minimum are not recommended for accurate control when using pressure independent controls. Minimum airflow for pressure dependent applications is O cfm. 4. Pressure independent controls may be set for O cfm, at or above the minimum airflow show in table 4, but not between. 5. Direct Digital Controllers are factory programmed. 6. Airflow rates above maximum shown are available. Contact your KMC representative for application assistance.

KSQ
Air Terminal KSQ Terminal Selection When selecting KSQ single duct variable air volume terminals, several factors must be considered to make the proper selection including: • • • •
occupied space, these ratings along with the acoustical environment in which the unit operates, will determine the perceived noise level. Noise generated within the terminal and emitted through the discharge air (discharge sound) will be attenuated by any duct work downstream of the terminal. The noise emitted through the casing of the terminal (radiated sound) will be attenuated by the room’s ceiling. Depending upon the application, either the radiated or discharge noise level will be the relative higher and determine the perceived noise level in the occupied space. The occupied space itself will provide further attenuation depending on the acoustical characteristics of the walls, floors and internal furnishings.
Air Flow and Air Pressure Drop Sound Heating (if required) Controls
Air Flow and Air Pressure Drop All KSQ units can operate over a wide range of airflow. The minimum airflow shown for each unit is the lowest airflow at which the airflow sensor can generate an adequately strong signal for the pressure independent controls to operate properly. The maximum airflow shown for each unit is based on the industry practice of limiting the inlet air velocity to reasonable levels. The units selected should be sized where the design airflow is between the maximum and minimum airflows shown in table 4. Referring to table 6 if 2378 CMH (1400 CFM) is the maximum design airflow, a unit with a 300mm inlet can be selected with an air pressure drop of0.01 inches (2.5pa) w.g.
All manufacturers must make certain assumptions on the acoustical environment of the application and then apply these assumptions to the unit’s sound power ratings to determine the resultant sound pressures and perceived noise level in the occupied space. While the ARI sound power ratings have been certified and can be accurately compared from one manufacturer to another, the NC values predicted will be dependent upon the acoustical assumptions made. When selecting terminals, check the attenuation assumptions before comparing cataloged NC values. KMC uses the ARI Standard 885, Appendix E attenuation assumptions for determining the anticipated noise levels. The attenuation assumptions in this standard are outlined in Table-2.
Sound Performance Tables 7 thru 11 indicate the sound power levels of each unit at varying air flow rates and inlet static pressures. Disregarding other factors and/or equipment that could contribute to the noise in the

Heating (if Required) Hot water heat Select the hot water coil that provides at least as much heating output as required (based on the design conditions). Using our example of a 300 mm (12”) size unit, if the design heating airflow is 1360 CMH (800 CFM) for the heating coil selection, the heating capacity desired is 8.5 kW (29 MBH), the entering water temperature is 82.3˚C (180 ˚ F) and the entering air temperature is 12.7˚C (55 ˚ F), using Table 14 would indicate that a 1 row coil supplied with 0.25 LPS (4 GPM ) of hot water would be required. The air pressure loss for the heating coil selected at the maximum design airflow for the terminal (2380 CMH i.e 1400 CFM) must be added to the KSQ terminal’s air pressure drop. The heating coil air pressure drops are also shown in Table 6. In our example, the air pressure drop across the coil is 60 Pa (0.24 inches w.g). This would be added to the termin al’s air pressure drop of 2.5 Pa (0.01 inches w.g) at the design maximum airflow of 2380 CMH (1400 CFM) , which results in a Total air pressure drop of 62.5 (0.25 inches w.g). Electric Heat The wattage of electric heat needed is determined by dividing the heating required in Mbh by 3.414, which results in the KW of heating required. Using our example, it would require 8.5 KW of electric heat to provide the 29 Mbh heating capacity. Using table 25, the electric coil with 8.5 KW would be selected. Electric heat can be staged or modulated. Note that the electric coil has an air proving switch, which requires a minimum of .07 inch w.g. Total pressure entering the coil to prove airflow. Also note that it’s prudent to check the air temperature leaving the heating coil at the design airflow. Using the previous example, the resulting leaving air temperature would be approximately 32°C (89°F), which would generally provide a comfortable environment and proper air distribution. Control Sequences A wide array of control sequences are available as standard on KMC‘s KSQ single duct variable air volume terminals.

= CMH x 1.204 x ΔTA / 3,600 = kW x2990 / CMH = kW / (LPS x 4.187)
Sizing Reheat Coils : 1. Knowing the heating load of the space (kW), room set point, and the air flow rate (CMH) during heating (based on minimum ventilation rates,max recommended discharge temp. for best ADPI, etc) determine the supply air temperature required to satisfy the load : Supply Air temperature = ( kW X2990 /CMH) + Room Temp. set point 2. The supply Air temperature in to the space is the required Leaving Air Temperature from the coil (assuming no duct heat loss). Applying energy transfer equations for electric or Hot water coils determines performance characteristics required to select coil : Hot Water / Electric Heater coils = CMH x 1.204 x ΔTA / 3,600
