This standard applies to all types and sizes of air-conditioning units, heat pumps, and chillers using direct-driven 250 mm to 750 mm (10 in. to 30 in.) diameter propeller fans, which, for the purposes of this standard, are called a "system." This standard covers system vibration...
This standard covers fans with rigid rotors generally found in commercial heating, ventilating and air conditioning; industrial process applications; mine/tunnel ventilation applications; and power generation applications. Other applications are not specifically excluded, except as follows:...
This standard applies to propeller fans for use in heating, refrigerating, and air-conditioning units. The fans may be of a built-up or monolithic construction and with or without resilient hubs. The sizes typically range from 10 in. (250 mm) to 30 in. (760 mm) in diameter. This...
This document sets out the specific procedures to be considered when carrying out vibration diagnostics of various types of fans and blowers. This document is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical, step-by-step,...

This part of ECMA-275 specifies methods for measuring the airborne noise emitted by small air-moving devices (AMDs), such as those used for cooling electronic, electrical, and mechanical equipment where the sound power level of the AMD is of interest. Examples of these AMDs include propeller...
The purpose of ISO 20154:2017 is to provide general guidelines on the design of ship vibration isolation based on the basic methodology of vibration isolation for shipboard machinery, for example, auxiliary engine, compressor, fan, pump, etc. A well-designed vibration...
