‘E’ Is For Energy Efficiency | Introducing The New E-Wheel

Having previously offered both the W and B series of backward curved impellers, Axair supplier partner Rosenberg have developed a new addition to the range; the E-Wheel.



Driven by an increased market requirement concerning noise levels Rosenberg’s new E-Series impeller design produces significant increases in energy efficiency and major reductions in operating noise levels. It features seven aerofoil design blades for high flow and low to medium pressure applications like computer room air conditioning and air handling (CRAC/CRAH), energy recovery ventilation (ERV), energy recovery units (ERUs), box and roof fans.

E-Series impellers have the same external dimensions as existing impellers and a similar airflow/pressure mix, but system energy efficiency is increased by 4% while the noise level is lowered by 3 to 5 dB(A) depending on system airflow and static pressure.

Key Features Summarised:

  • Low Noise Volume (reduces operating noise by 3 – 5dB depending on system)
  • High Efficiency (4% increase compared with previous design)
  • Glass fibre Reinforced ABS impeller
  • Meets all 2015 Erp Legislation
  • Suitable for high flow and low-medium pressure applications
  • 450 diameter available in multiple single & 3 phase AC and 3 phase EC variants

E-Series fans are available with EC (electronically commutated) and AC external rotor motors and meet ErP 2015 energy efficiency requirements with all available motor combinations.

Thermal contacts provide standard motor protection. All are CE, UL and RoHS approved. Different input voltages are available.

For now, the E-wheel is available in a 450mm diameter with other sizes coming in the near future. To download a copy of the 450 diameter E-wheel datasheet Click Here, alternatively, contact us to discuss how the new series can improve the efficiency of your project.
