AHRI 430 (I-P/2020): Performance Rating of Central Station Air-handling Unit Supply Fans
This standard applies to a factory-made encased assembly consisting of a supply fan or fans in parallel which may also include other necessary equipment to perform one or more of the functions of circulating, cleaning, heating, cooling, humidifying, dehumidifying and mixing of air and which does not contain a source of mechanical cooling. The CSAHU must have a maximum design external static pressure (ESP) greater than 1.0 inches [250 Pa]. This standard establishes the test requirements, rating requirements, and minimum data requirements for Fan Speed, Fan Electrical Power, and Shaft Power.
