LAMINAR FLOW: GENERALConventional vs. Critical Space Applications
With human comfort in mind, conventional air distributionstrategies typically employ rapid mixing of supply and room airfor thermal equalization and effective ventilation (or ventilation
efficiency), with low air velocities within the occupied zone fordraft free conditions (figure 1) Because mixing of air is desirable, turbulent flow is preferred.Although thermal comfort is important within critical spaces,airborne particle control is often the basis for the application ofair distribution systems in these spaces. Control refers to themanagement of the quantity, type/size, and location of particles,and is dictated by the space function. In these cases,entrainment of room air with the clean, supply air is notdesirable and specialized air distribution devices must beconsidered.
What are Particles?
Particles can exist as bacteria (Tuberculosis, Legionnaire’sdisease), viruses (chicken pox, measles), pollen, skin flakes, hair,dust, live or dead organisms, lint, etc. Particles may beconsidered contaminants when they negatively influence aprocess, procedure, or human / animal physiology. Sources ofexternal microbial contaminants in a space include the supply airto the space or infiltration through room openings from otherspaces. These are easily controlled with air filtration and spacepressurization. Internal sources include equipment and people.Research indicates that in hospital operating rooms the surgicalteam and their activities contribute the greatest quantity ofcontaminants to the space. Considering this continuous streamof contaminants is being shed over and around the operatingtable, air distribution strategies for these spaces musteffectively carry away particles to minimize surgical siteinfections.
Measuring Particles
Space cleanliness is often quantified using Federal Standard209 that specifies particulate cleanliness classes and measuresthe number and size of particles per cubic foot of air sampled inthe space (graph 1 & table 1). For example, the semiconductorindustry typically requires Class 100 or cleaner, meaning nomore than 100 particles/ft3 of a size .5µm and larger.

LAMINAR FLOW CONCEPTS
Laminar Flow
Laminar or streamline airflow is defined as airflow in which theentire body of air moves with steady, uniform velocity alongparallel flow lines with a minimum of eddies – a piston-likedelivery of air.
Air Piston Flow
Laminar flow distribution panels consist of thousands of smallholes per square foot. The small air jets exit each hole, movingparallel to each other to form an air piston. As the individual jetscoalesce, the edge of the air piston actually necks inward a bitwithin the first few inches from the panel, and expands outwardas the piston travels downward.
Boundary Mixing
Laminar flow panels discharge air at a uniform velocity andcreate an air shower or air piston that moves in free space withedge boundary effects occurring between the column of clean,supply air and the surrounding room air. The perimeterboundary is not stationary, but moves downward in a turbulentmanner. It is at the boundary layer where mixing occurs, andsurrounding particulate is entrained into the air stream.
Cooling Differential
Surprisingly, the cooling differential (supply air and room airtemperature difference) has very little influence on the airvelocity and projection distance downward. This is because themass of cooler, supply air constituting the laminar piston withinits boundary layer, exhibits nearly a zero vertical temperaturedifference, and consequently, no buoyancy effects due to airdensity.
Panel Free Area
The laminar panel open perforated area has little impact uponthe sound level and projection distance when considering holeswith relatively small diameters. Increased momentum due tomass and velocity increase is discernable only within a fewinches of the panel only (10-40 hole diameters).

LAMINAR FLOW STRATEGIESLaminar flow one-pass systems (sometimes referred to as “plugflow”) are used to bathe an area in a clean, continuous showerof filtered air. The laminar panel is designed to minimize mixing(non-aspirating), while providing a unidirectional air stream thatis perpendicular to a perforated panel. Particle control isachieved by removing the particles from the source, and awayfrom a defined critical area. Air distribution systems for particlecontrol will typically consist of horizontal laminar flow, verticallaminar flow, or a hybrid system of vertical laminar flow coupledwith perimeter air curtains.
Horizontal Laminar Flow Systems
Horizontal flow applications (figure 2) with installed wall systemscommonly provide one pass, unidirectional flow in spaces utilizedfor sensitive processes or activities, and where turbulent eddiesor whirlpools caused by obstructions have been evaluated anddeemed acceptable. Inherent benefits of these systems includenearly unidirectional flow from the wall supply air outlets to theopposing wall air exhaust or returns, easy monitoring andreplacement of final filters, and the physical installation ofequipment. Consideration must be given to upstream-downstream relationships with respect to particle flow, and thefact that critical work envelopes in series with each other maybe affected. Horizontal flow may also be considered to treatsmall, bench top work envelopes.
Vertical Laminar Flow Systems-Entire Ceilings
Vertical flow applications with active laminar panels filling theentire ceiling provides complete wall to wall coverage of thespace by bathing the entire space with clean air, and is the bestarrangement for many clean space applications (figure 3). The orientation of laminar panels above the critical workenvelope typically provides the most direct, unobstructed path ofairflow. This approach requires high air change rates, and maynot be practical for certain applications due to cost orinstallation constraints. Vertical hanging curtains (figure 4) or other partition materials may be utilized to create a “micro”clean space within a larger space to achieve the benefits ofcomplete ceiling coverage but at a lower operating cost.

Vertical Laminar Flow Systems- Limited Ceiling Array
Vertical flow applications consisting of an array of ceiling laminarflow panels strategically located just over the critical workenvelope are often utilized in operating/surgical suites andsimilarly critical areas in health care facilities (figure 5). It is generally accepted that a properly installed and operatedsystem, providing a clean source of supply air, will reduce theincidence of infections due to airborne contaminants.Contaminant control within health care facilities varies by space,but the operating or surgical suite is by far the most aseptic(control of bacterial growth within acceptable limits). Thisarrangement is preferred where an entire ceiling array is notpractical, but can still require high air change rates based onthe size of the treated area. Because of mixing at the boundaryof the air piston, the perimeter of laminar flow panel arrayshould be sized to extend beyond the critical work envelope by atleast 6" (figures 5 & 6).
Hybrid Systems - Vertical Laminar Flow with PerimeterCurtains (Anemostat AORTA System)
Hybrid air distribution systems have evolved utilizing the benefitsof laminar systems as described above, and ideally include acontinuous perimeter air curtain around an interior laminar flowpanel or array of panels, essentially creating a “space within aspace” (figure 7). Because particles enter the laminar flow airstream at the boundary of the stream by entrainment, aircurtains (angled outward from 5-15°) are utilized as a buffer toisolate the critical work envelope. The perimeter curtain reducesthe quantity of particles entering the laminar flow field from thesurrounding, less clean air. The interior “cube” formed by the aircurtains maintains a positive pressure relationship compared tothe exterior or surrounding area outside the air curtains,resulting in high to low pressure particle movement. The totalsupply air quantity for the space is typically proportioned with a2:1 ratio - 1/3 for the central laminar flow field, and remaining2/3 for the perimeter curtains. These systems typically requirelower overall air change rates for the space, with higher airchange rates resulting in the cube within the air curtain.
RETURN / EXHAUST GRILLESA minimum of two grilles or registers located low in the sidewalls at least 3” above the floor typically on opposite sides of theroom is recommended (figure 7). Particulate movement fromthe critical envelope down along the floor and out of the spacerepresents the shortest path for removal. The air quantityextracted from the space through these grilles will determinethe room pressure and the pressure relationship of the spacewith respect to adjacent spaces, either positive (exfiltration orflow out of the space to an adjacent space), negative (infiltrationor flow into the space from an adjacent space), or neutral.Guidelines for space pressure are published by ASHRAE, AIA,CAN/CSI, and other code authorities based on space function.

DESIGN FACTORSDesign factors pertinent to equipment selection and placementinclude:
Sound level / Room NC – refer to ASHRAE handbooks forrecommended space sound levels. Air outlet sound levels can beadequately controlled by selecting an appropriate neck size for areasonable duct velocity. The additive sound of multiple inlets andoutlets should also be considered.
Total supply air quantity (CFM) – this is determined byconsidering both the required air change rate and space coolingloads. The air change rate is often the determinant. AirChanges per Hour (ACH) is the time rate at which the room airis replaced based on total supply air quantity into the space androom volume. Table 2 reflects guidelines from ASHRAE and theAIA (American Institute of Architects) regarding ventilation ratesfor various space functions in health care facilities. To calculateCFM, the required total supply air to a space:
CFM = ( V x ACH ) / 60
where:
V = room volume, ft3ACH = air changes per hour
For example, a 4000 ft3 room volume assuming 25 air changesper hour (25 ACH) requires about 1,670 CFM into the space.
Special modes of operation should be considered which mayrequire higher air flow rates and cooling differentials. This mayinclude procedures such as cardiac surgery.
Critical Work Envelope (CWE) – the location within the roomidentified as a zone of significant influence on a process orprocedure taking place, as compared to other envelopes withinthe same room. In surgical suites, this includes the patient andsurrounding team.
Projection Distance – the required distance, in feet, resulting ina velocity at that distance to effectively remove particulate awayfrom the CWE. In surgical suites, this is the distance from thelaminar flow panels in the ceiling down to about 6” above the
operating table. There has been considerable debate regardingthe ideal terminal velocities in the critical work envelope forhospital operating rooms to minimize SSI (surgical site infections)and control contaminants. Past recommendations of the CDC(Centers for Disease Control and Prevention) and HICPAC(Healthcare Infection Control Practices Advisory Committee)have suggested 60-100 fpm over the operating field. New AIA(American Institute of Architects) and NIH (National Institute ofHealth) guidelines are recommending velocities of 25-35 fpm.The recommendations of these organizations are based on thelatest and most current research available, and may change asnew research becomes available. Anemostat’s Multi-Vent® seriesof laminar flow panels have been designed for flow uniformity atboth low and high terminal velocities as recommended by theseagencies.
Laminar Panel Active Area – the size of an array of laminarpanels required to cover the critical work envelope with an airpiston of sufficient velocity to effectively carry away particulates.For applications with laminar flow panels only, the array shouldextend at least 6” beyond the edge of the critical work envelope.
Supply Air Temperature Differential (∆T) – the differencebetween the actual space temperature and the supply airtemperature. With space heating and cooling loads, the supplyair must be warmer or colder than the design set point of thespace. Applications requiring heated supply air require specialattention as laminar flow air distribution is designed to performwith isothermal or cold supply air systems only.
Obstructions – laminar flow air streams are disrupted fromtheir paths by obstructions such as lights, IV poles, and otherancillary equipment. Priority should be given to maintainingunobstructed flow during design. Obstructions are inevitable andthe preferred arrangement is to include the obstruction entirelywithin the perimeter of the CWE to keep turbulent eddies totallywithin the clean air column. Particulate that strikes an object willtypically move around and be carried away from it within the airstream.
Heat Sources – equipment and surgical teams create thermalplumes that oppose the direction of the laminar air stream toflush away particles. These sources should be located sufficientlywithin the CWE, or completely outside the CWE.

model MV-HEPLaminar Flow Panel w/HEPA Filter
product description
C R I T I CAL E N V I R O N M E NT
APPLICATION• Use where “room-side replaceable” HEPA or ULPA
filters are required. Multi-Vent® Filter units aredesigned for easy replacement of filters
• Multi-Vent® laminar flow panels provide aunidirectional “piston” of clean air over criticalwork envelopes effectively isolating the area fromexternal airborne contaminants
• Superior filter design maximizes efficiency andminimizes pressure loss – each filter isdynamically tested at the factory and labeled withthe results.
• Laminar flow reduces entrainment of recirculated,contaminated air
• Ideal for use in class 10 to 1000 spaces,including clean rooms and surgical suites
• Carries particles, introduced by humans into thecritical area, AWAY from the critical area
• Laminar panels can be utilized individually to coversmaller, critical areas, or built-up into an array ofmultiple panels covering large areas
UNIT FEATURES• 12" x 48", 24" x 24", 24" x 48" standard sizes.
Other sizes available, contact your localAnemostat representative for details.
• Multi-Vent® -filter interface includes knife edge intofilter gel seals for zero leak performance
• DOP, pressure ports, and an aerosol injectiontube system simplify field verification andcertification
• Perforated face is 13% open, and removable via1/4 turn fasteners for cleaning
• Face is hinged and swings down 90° for easycleaning. Safety cables prevent face fromaccidentally swinging down.

MODEL MV-2Anemostat Multi-Vent® Model MV-2 Laminar Flow Ceiling Panelsshall be installed where shown on the drawings, and shallintegrate with the ceiling type shown. For hard surfaceinstallations, multiple laminar flow panels shall be attached directlyto each other, as shown, to form a contiguous array of panels thatcreates a single, downward piston of laminar flow air, to provideparticle control of the work space below. The perimeter edges ofthe panel array shall include trim strips to conceal rough ceilingopening.
The non-aspirating laminar flow panels shall utilize a dual chamberplenum design consisting of an upper chamber with a top, roundinlet collar (suitable for attachment of flexible duct of the sizeshown on the plans), lower chamber, and a perforated face, toestablish a unidirectional flow of air. Air shall be distributed fromthe upper to lower chamber through multiple “V” shaped airdiffusion baskets located along the length of the assembly togenerate a uniform air flow across the entire face. Single plenumdesigns or designs utilizing flat perforated plates to equalize floware not acceptable. The distribution of air through the face shallnot be influenced by inlet pressure, damper position, or supplyduct arrangement.
The laminar flow panel assembly shall include a volume damperlocated in the neck to assist in air balancing, and shall beadjustable from the room without removal of the face. A plugbutton shall be provided in the face for the access hole. Theplenum assembly shall include integral hanging tabs forsupporting unit overhead. The removable face shall be attachedto the assembly with 1/4 turn fasteners and shall include closedcell gaskets. Stainless steel safety cables shall prevent accidentaldropping of the panel.
