SynC · Topic
These are the standards in the SynC Standards library that cover Fans. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
General-purpose, field- or factory-installed air-moving equipment serving commercial, institutional, and light-industrial HVAC systems. Covers centrifugal fans (housed and plenum/plug type), axial fans (vaneaxial, tubeaxial, and propeller), inline (cabinet and tubular) fans, utility/SWSI exhaust fans, roof- and wall-mounted power ventilators (upblast and downblast), ceiling-mounted exhaust fans, and dedicated kitchen grease-exhaust fans. Addresses aerodynamic and sound rating and certification (AMCA 210 / 300 / 211 / 311), Fan Energy Index compliance under ASHRAE 90.1 (AMCA 208), AMCA construction class and drive arrangement, direct-drive and belt-drive selection, induction and electronically commutated (EC) motors, bearings, materials and finishes, spark-resistant construction for hazardous exhaust (AMCA 99), accessories, vibration isolation, and the electrical and controls interface to variable-frequency drives and the building automation system.
