Buffalo Air Handling Unit

General Construction
• 2" double wall, 14 or 16 gauge outer panels, 18 or 20 gauge inner panels (solid or perforated), 
  3#/ft³ density fiberglass insulation.
• Galvanized steel, aluminum or stainless steel casings and floors
• Welded structural steel channel bases.
• 10 gauge or 3/16" welded floors in painted steel, galvanized, aluminum or stainless steel; 
  treadplate optional.
• IAQ triple-sloped, 12 gauge, stainless steel drain pans in cooling coil 
  sections for complete condensate removal.
• Access doors for inspection, service and maintenance designed to 
  open opposite the unit operating pressure.
• Maximum 1% leakage rate.

Fan Section
• Fan, motor and drive are mounted on a welded heavy duty steel vibration base with spring 
  isolators properly selected for the specified vibration efficiency. Inertia bases are available for 
  critical applications.
• Complete fan assembly is factory run, tested and dynamically balanced not to exceed 0.16 ips 
  horizontally and vertically, and 0.32 ips axially as measured by an Entek IRD computer balance 
  analyzer.
• Centrifugal fans (DWDI) for maximum efficiency in return and supply fan applications.
• Plenum fans for return air applications and supply air applications with multiple discharges.
• Axial fans for reduced sound levels in the low octave bands.
• Direct drive available to meet critical balance criteria, and eliminate the possibility of belt dust 
  and the necessity of belt maintenance.
• Full height, full width diffuser plate in blow through applications reduces pressure drop by 
  50% or more when compared to conventional diffusers.

Coil Section
• Chilled water and glycol cooling coils, hot water and glycol, and 
  steam heating coils.
• IAQ triple-sloped, 12 gauge stainless steel drain pans in cooling
  coil sections.
• Support racks for independent coil removal available in stainless, 
  galvanized or painted steel.
• Intermediate drain pans, troughs and downspouts for stacked coils.
• Steam coils raised for proper condensate removal. 
• Preferred manufacturer is Aerofin.
