It is relatively easy to calculate how much horsepower a fan is consuming in the field. Once calculated, this information can be used to identify the additional amount of flow and pressure the fan can produce within the limitations of the motor. To perform the calculations, we just need two field measurements which include the motors amperage draw and the line voltage (both can be measured with a voltage meter) and two items shown on the motor’s nameplate. This includes motor efficiency (often shown as “NEMA NOM. EFF.”) and power factor (shown as “PF”).  

New York Blower continues to be the experts in the air-moving industry, going back to the founders of the company. Henry Mathis, Vice-President of nyb at the time, wrote an article about Fan Performance and Selection that was originally published in October, 1932 in the publication The Aerologist.

AirEng, a nyb subsidiary, has been busy lying the groundwork for mechanical and electrical construction for the Gwalia project. They are providing a turnkey ventilation system for Australia's oldest and deepest golf mine, including primary fans, the electrical power unit, and civil construction systems. One major challenge is getting proper ventilation to the workers underground.
