LONGWELL ADH 900-K fan assembly specification

On May 18, 2026, LONGWELL opened a project to provide an engineering assembly drawing for a single ADH 900-K double-inlet centrifugal fan unit without an integrated motor. The customer requirement specified a complete assembly set—including the impeller, scroll housing, bearings, and shaft—to be retrofitted and paired with an external 30 kW motor. The drawing required itemized identification of all included components.
