GB/T 22712-2008 Specification for G series cooling fans applying to variable frequency motors
Basic Information
Scope
This standard specifies the types, basic parameters, and dimensions of G-series cooling fans for YVF2 series (IP54) frequency-controlled three-phase asynchronous motors powered by frequency converters, as well as technical requirements, inspection rules, marking, packaging, and warranty period requirements.
This standard applies to G-series cooling fans (axial flow type) for YVF2 series (IP54) frequency-controlled three-phase asynchronous motors powered by frequency converters (hereinafter referred to as fans). Fans for other series of frequency-controlled three-phase asynchronous motors powered by frequency converters can also refer to this standard for fan selection. All fans derived from this fan can also refer to and implement this standard.
