AAON M3 Modular Air Handler

         Indoor Air Quality
               (IAQ)
M3 - Indoor Air Quality Features
• Double-sloped drain pan with carry-
  over containment.
• Benefits:
   • Ensures positive drainage
   • Prevents unwanted water carryover from
     escaping into occupied space, ductwork or
     outside of the drain pan
 SPECIFICATION

     •    Construct drain pans from 304 stainless steel
          with cross break and double sloping pitch to
          drain connection. The drain pan shall extend
          past the downstream face of the coil by a
          minimum of 12”.
M3 - Indoor Air Quality Features
• Stainless Steel Drain Pan standard on all
  AAON Modular Air Handlers
• Benefits:
    • High resistance to corrosion prevents leaks that
      can occur to due to deteriorated drain pan



 SPECIFICATION

•   Construct drain pans from 304 stainless steel with
    cross break and double sloping pitch to drain
    connection.
M3 - Indoor Air Quality Features
• Cleanable Drain
  Pan / Raised Coil
• Benefits:
    • Readily cleanable
      drain pan promotes
      improved indoor air
      quality.

 SPECIFICATION

•   Coil shall be mechanically supported above the drain
    pan by minimum of 2” by coil supports that aid in
    drain pan cleaning. Hat channels and other devices
    that prevent access to the drain pan shall not be
    acceptable.
M3 - Indoor Air Quality Features
• Cleanable Metal Interior Liners
• Benefits:
    • Cleanable metal liner provides a smooth surface
      that is easily wiped down.
    • Eliminates materials on the interior of air handler
      that tend to trap dirt and moisture and can become
      breeding grounds for mold and mildew.

 SPECIFICATION

•   Panels and access doors shall be constructed with a
    cleanable metal interior liner. Interior liners
    constructed of fibrous glass, other types of
    insulation or material that may trap dirt and
    moisture are not acceptable.
M3 - Indoor Air Quality Features
• Hinged Access is standard on AAON M3.
• Benefits:
    • An important element in any program to combat
      the growth and distribution of mold is good
      maintenance. Key system components must be
      inspected and cleaned on a regular basis.
    • A rule of maintenance is equipment that is not easy
      to maintain won't be.
 SPECIFICATION

•   Access Doors shall be flush mounted to cabinetry,
    with stainless steel piano-type hinges, latch and
    full size (4.5" minimum) handle assembly. Door shall
    swing outward for unit sections under negative
    pressure (inward for unit sections under positive
    pressure).
M3 - Indoor Air Quality Features
• Less than 1% leakage at +/- 8” w.g.
• Benefits:
    • Reduce amount of unfiltered,
      unconditioned air into space.
    • Reduced opportunity for infiltration to
      condense inside unit walls.
    • Reduced opportunity for exfiltration to
      condense on outside of unit walls.


 SPECIFICATION

•   The completed cabinet casing leakage rate shall not
    exceed 1% when tested at 8” of static pressure.
    Caulking of unit panel seams is not allowed.
AAON M3 Modular Air Handler

        Energy & Economics
M3 - Energy & Economic Features
• Less than 1% leakage at +/- 8” w.g.
• Benefits:
    • Reduction of unconditioned air entering air unit
      downstream of coil for negative pressure system.
    • Reduction of conditioned air leaving air unit for
      positive pressure system.


 SPECIFICATION

•   The completed cabinet casing leakage rate shall not
    exceed 1% when tested at 8” of static pressure.
    Caulking of unit panel seams is not allowed. The
    casing leakage rate shall not exceed 0.2 cfm per
    square foot of cabinet area at 5" static pressure.
M3 - Energy & Economic Features
• Backward Curved, Direct-Drive
Plenum Blowers
• Benefits:
    • Backward curved fans are more efficient, quieter and can
      handle higher static pressures than forward curved fans.
    • Direct drive plenum blowers are more efficient than belt
      driven plenum blowers because no energy is lost due to
      sound creation, friction and wear of the belt.
 SPECIFICATION

•   Provide single width, single inlet, un-housed,
    backward curved, centrifugal plenum supply [return]
    fan(s). The fan shall be directly driven by the
    motor. Fans driven by belts shall not be acceptable.
M3 - Energy & Economic Features
• Slide Out Coil Construction
• Benefits:
    • Easy service of upper or lower coil
      assembly.
    • Coils are removable from either side
      and independently supported on
      tracks.
    • Upper and lower coils can be
      serviced independently.
 SPECIFICATION
•   All coils shall be installed on tracks for easy removal
    from the air handling unit. All coils shall be able to be
    removed from left or right hand side of the unit. Units
    that require disassembly of the unit for coil removal are
    not acceptable. Upper and lower coils shall be capable of
    independent removal. Units that require both the upper and
    lower coil to be removed for the service of one coil are
    not acceptable.
M3 - Energy & Economic Features
• L/240 Deflection Capability
• Benefits:
    • Less fatigue during operational pressures,
      which leads to reduced opportunities for         L
      leakage over time.                                               D
    • Less flexing and bowing during rigging and
      easier jobsite assembly of modules.
    • It is the panel deflection not the panel gauge       D < L/240
      that determines the rigidness of a panel.
 SPECIFICATION

•   Panel deflection shall not exceed L/240 ratio
    at 125% of design static pressure, maximum 8
    inches of positive or negative static pressure.
    Deflection shall be measured at the midpoint of
    the panel height.
M3 - Energy & Economic Features
• Foam R-13 to R-19 insulation
• Benefits:
    • Closed cell foam insulation has more than twice the
      insulating value of ½ lb. density fiberglass insulation of the
      same thickness.
        • 2” AAON foam insulation = R-13
        • 2” ½ lb. density fiberglass insulation = R-3
    • Provides consistent insulation throughout the air handler
      construction.
 SPECIFICATION

•   The air handling unit’s walls and roof shall be
    insulated to meet a minimum thermal conductivity (R
    value) of 13 BTU/hr-ft2-F.
•   The air handling unit’s floor shall be insulated to
    meet a minimum thermal conductivity (R value) of 19
    BTU/hr-ft2-F.
M3 - Energy & Economic Features
• Interchangeable Panels & Access Doors
• Benefits:
        • Easy field exchange of mechanically fastened
          panel to hinged access panel.
        • Provides flexibility at jobsite if unforeseen
          obstacles prevent access to planned entry.


 SPECIFICATION

•   Panels and access doors shall be constructed such
    that panels and access door are interchangeable from
    side to side of the unit. Access doors shall be
    symmetrically constructed such that door handing can
    be reversed by rotating the door 180 degrees.

          sensitive applications.
        • Isolators are specifically sized
          for each fan assembly.

 SPECIFICATION

•   Fan and motor shall be mounted internally on a steel
    base. Fan and motor assembly shall be mounted on 1"
    deflection spring vibration type isolators inside
    cabinetry. Unit base, rigid mounted inside cabinetry
    shall not be acceptable.
M3 - Acoustical Features
• Multiple Fan Selections Available via
  AAONEcat™.
• Benefits:
          • Multiple fan assemblies can be selected from on
            each job to provide flexibility.
          • Fan options can be reviewed for important criteria
            including, sound power levels, cost and
            redundancy.
  GUIDE
M3 - Acoustical Features
• Double Wall Construction Decreases
  Resonated Sound
• Benefits:
        • Double wall construction provides excellent
          temperature and sound insulation.
        • Spaces surrounding the air handler are quieter
          than would be with standard single wall
          construction.
 SPECIFICATION

•   Panels and access doors shall be constructed as a 2-
    inch (50 mm) nominal thick; thermal broke to
    eliminate any metal conductive path through the
    panel double wall assembly, injected with foam
    insulation for an R-value of not less than R-13.
