Description
LWAA4E450S-5MEB-15 at a glance
The LONGWELL LWAA4E450S-5MEB-15 is a Ø450 mm AC axial fan with an external-rotor motor delivering up to 5665 m³/h, 1400 rpm, 60 dB(A). Axial fans move large air volumes against low resistance, which makes them the standard choice wherever a heat exchanger, condenser or enclosure has to be cooled rather than ducted.
Every figure in the tables below is the catalogue rating for this exact model — impeller diameter, blade count, guard type, air direction and connection style are all fixed by the type code, so what you order is what you get. The performance curve and dimensional drawing further down are model-specific too.
