Fan Vibration Specifications
Engineers specifying allowable fan vibration levels are challenged to balance the need for lower initial equipment cost with the need for higher equipment reliability. This is especially important in critical applications. This article is a case study of a multiyear process that addressed the balancing of these competing needs as they related to critical pharmaceutical cleanroom applications. The knowledge obtained is transferable to other critical applications. Units: DualCitation: ASHRAE Journal, vol. 50, no. 2
