Axial fan MAXVENTOWLET

industrialgalvanised steelstainless steel

Overview
The MAXventowlet medium-pressure axial fan integrates ZIEHL-ABEGG's biomimetic blade geometry to deliver reduced acoustic emissions and a high performance density for industrial ventilation applications. The modular design supports blade diameters from 315 to 1,400 mm and offers multiple material and housing configurations to match site requirements.

Product specification
This modular, high-performance axial fan is configurable to customer specifications. The biomimetic blade design provides efficient airflow with reduced noise. Options include ZAmid® high-performance composite blades, alternative blade materials, short and long housings per Eurovent, and AC or EC (ECblue) motor technologies. The MAXventowlet range meets the current ErP Directive and is available in ATEX category 2 and 3 configurations. Performance: flow rates up to 144,500 m3/h and static pressures up to 2,200 Pa.
