Axial fan MAXvent owlet

ACEC motorindustrial

Overview
A few years ago, ZIEHL-ABEGG set an important milestone with the introduction of biomimetic blades. The third generation of MAXventowlet medium-pressure fans benefits from this proven design offering low noise emissions (improvement up to 12 dBA compared to previous models). The unique ZAmid® high performance composite material makes the light blades corrosion-free and ideally suited for medium pressure ranges. The modular MAXventowlet system (up to a blade diameter of 1,400 mm) provides high adaptability with different blade materials, housing lengths and number of blades. The Ex design provides suitability for applications with flammable gases and dusts.

Product specification
This modular, high-performance axial fan can be optimally adapted to individual requirements. The biomimetic blade design ensures optimal efficiency with low noise development and high performance density thanks to internal rotor motors. Available with AC and EC technology (ECblue). Sizes available from 315 – 1,400 mm with flow rates up to 144,500 m3/h and static pressures up to 2,200 Pa.

Properties & special features
