EC fans cool towers efficiently

EBMPAPST W3GZ50 Axial fan with AxiTop diffuser and 1.250mm double flange housing size is for use in cooling towers. Product’s robust design includes a special coating for metal parts and electronics circuit boards, protecting it from extremely harsh ambient conditions with 100% humidity. Designed with Electronically Commutated (EC) technology, units cut air flow in half, thus reducing noise level by 15dB, whereas an improvement of only 3dB is attained with ac fans. Products are also suited for use in FanGrid arrangement, a system of centrifugal or axial fans operating in parallel.
