About ebm-papst RadiCal Series
Backward Curved EC Centrifugal Fans
The ebm-papst RadiCal series is the benchmark of compact modular EC centrifugal ventilation technology. Equipped with ebm-papst proprietary GreenTech EC electronically commutated motors, these backward curved centrifugal fans deliver excellent static pressure performance. Different from axial fans, RadiCal units operate efficiently under high air flow resistance caused by filters and complex ductwork.
With modular construction, flexible intelligent control options and long service life, RadiCal fans are widely adopted globally for data center thermal management, precision air conditioning, telecom thermal control and industrial HVAC systems.
We stock 100% genuine original ebm-papst RadiCal EC centrifugal fans. Highly competitive pricing, up to 40%-90% lower than official list prices. Complete datasheets, performance test documents and reliable after-sales service are available for all orders.
