10 System Considerations Air Plenum Design Guidelines To assure optimum performance and be able to use the system effect coefficients below, the following guidelines should be adhered to in the plenum design: 1. Flexible connections at the inlet are recommended to isolate vibration.
11 System Considerations 3. System effects for plenum discharges must also be calculated and added to the design pressure. In a properly designed plenum (see Duct System Effect section), the system effect coefficient (C o ) depends on the orientation of the discharge relative to the fan and duct connection (if any).
Direct drive construction offers many advantages for commercial or industrial air handling applications. - Reduced maintenance (no belts and shaft bearings to service) - Compact housing design require.
