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.
