Axial fan airfoil high efficiency

EMAX axial fans

Multi-Wing’s EMAX axial fan series is designed for ventilation applications that require high efficiency rates. 

EMAX_content

Multi-Wing’s high efficiency fan EMAX4 has a unique profile which pushes efficiencies of standard axial fans. It helps minimising the power consumption of your product enabling you to comply with the ErP Directive. It can even help you meet the proposed 2020 requirements, Stage III. And it does so more quietly than before - reducing noise emission by 2-3dB.
The EMAX4 is designed to fit our existing range of hubs and therefore retains all the advantages of the Multi-Wing modular system with variable pitch angles. Avaliable in 5, 6, 7, 9 and 12-bladed configurations with a diameter range from 624 mm to 920 mm.
The high number of possible configurations means that solutions incorporating the EMAX4 is even more flexible than standard solutions. The EMAX4 provides high efficiency rates for a majority of the performance curve and not only in the best efficiency point.

Your benefits:

EMAX profile
  • ErP compliant axial fan with exceptionally high efficiency capabilities.
  • Improving efficiency by 2-4%.
  • Highly adjustable performance as it enables 23 different pitch angles.
  • Available for 5 different hub sizes with different mounting options.
  • Reducing sound emission by up to 2-3dB.
  • Diameter range from 624mm to 920mm
  • Fan blades available in PPG and PAG, hub parts in a pressure die cast silumin alloy.

EMAX - an ErP compliant fan

The unique EMAX profile is designed to meet the requirements of the ErP Directive. With its high efficiency capabilities it helps minimising the power comsumption of the final product. The EMAX can even help you meet proposed 2020 requirements (Stage III). Connected to an eco-design 2020 compliant 2-4-6 pole motor, the EMAX is significantly above the proposed 2020 requirements.

Does the ErP Directive apply to your product?

The ErP Directive applies to energy-related products placed on the EU market. It applies to suppliers of individual components, to suppliers of complete fan sets, and to suppliers integrating electrical motors and fans into their products either as parts or complete fan sets. The fan industry is impacted by the Commission Regulation (EU) No 327 on fans driven by electrical motors with an input power between 0,125 kW and 500 kW and the Commission Regulation (EU) No 640/2009 on electrical motors.

Multi-Wing can assist you with detailed information on ErP compliance. Visit our web site erpfans.eu or contact your local sales person.
Select ErP compliant fans using our selection software Multi-Wing Optimiser. It also provides the necessary documentation.

Dryers and kilns

The main success criterion is to achieve homogeneous drying whether that is of timber or bricks. To comply with these demands we can offer a range of true reversible impellers producing equal air flow and pressure in both operating directions.

Z series axial fans

The Z Series represents the medium diameter axial fans in the Multi-Wing product line, with a range in diameters from 315 mm to 1295 mm.

True reversible profile

Multi-Wing’s innovative true reversible axial fan series is designed for applications that require high efficiency in a reversible configuration.

Airfoil profile

Multi-Wing’s airfoil axial fan series can be used in almost any air moving application such as cooling towers, engine cooling.

PressureMAX profile

This remarkable axial fan can help your company meet the Tier 4 emissions standards and the Stage III B Standards for off highway engines.

Increasing arc profile

Multi-Wing’s increasing arc axial fan series is a suitable solution in applications that demand high performance in challenging inlet conditions.
