About EC Backward

The EC Backward category represents ebm-papst's comprehensive selection of electronically commutated centrifugal fans with backward-curved impellers. With 357 products ranging from compact 24V units to high-performance 48V models, this is the largest single sub-collection within the ebm-papst catalog.

EC backward curved fans deliver exceptional static pressure and airflow efficiency, making them ideal for applications requiring medium to high pressure — including data center cabinet cooling, inverter drives, industrial machinery ventilation, and telecommunications equipment. The product lineup covers voltage inputs from 24V to 48V and power outputs from 19W up to 325W, with a broad spectrum of impeller diameters to match different system resistance requirements.

Every model in this category benefits from ebm-papst's GreenTech EC technology, which reduces energy consumption by up to 50% compared to conventional AC fans while maintaining precise speed control and extended service life.

Bag

Bag packaging indicates that a specified quantity of product is packaged by the manufacturer in a bag, sealed pouch, or similar container and sold as a unit without repackaging. It is also used to describe kits/assortments where components are packaged in separate bags according to part number or parametric value, rather than in a compartmentalized box or similar rigid container.
