Axial fan airfoil high efficiency

Multi-Wing ƐPS

A new add-on to close the gap between the shroud and the fan.


New to the extensive range of modular Multi-Wing products are the Multi-Wing ePS™. Multi-Wing ePS™ are bristles which are attached to the end of the blade as adhesive "eyebrows". They are an ingenious yet highly effective addition to today's best fan technology, simply reducing the gap between the blade and its encasement, and minimising turbulence in the blade itself.

The result? Tangible improvements in fan performance, blades that move more smoothly, and fans that operate with less noise and higher efficiency.


Multi-Wing ePS™ is applicable on every Multi-Wing fan blade and the smart adhesive system enables easy maintenance, even in the field. The bristles provide high mechanical as well as chemical resistance making it usable in multiple industries and applications. They are usable for temperatures up to 120 degrees C, the same operating range as our PAG fans.

Static strength tests show that Multi-Wing ePS™ can withstand loads of more than 40N/mm allowing the usual max operating speed for PAG fans used particularly in the toughest environments such as in Off-Road applications. Fatigues testing prove that performance and noise remain unchanged even after 400.000 impacts.

Chemical resistance test at third party institute shows no or little deterioration of Multi-Wing ePS™ when exposed to hydraulic oil, diesel fuel, coolant, refrigiant R134a, and lubricant. 


Your benefits:

  • Improvements on performance, pressure, noise and efficiency

Stationary applications

Stationary equipment is typically compressors and generator sets often used as emergency equipment either at hospitals, mines or off-shore sites.

Wind turbines

This sub segment is very similar to the radiator manufacturing. However, as the wind turbines are often erected as off-shore installations the level of the demands are higher.

Broad paddle profile

Multi-Wing’s broad paddle axial fan series is designed for coil applications with low speed motors and moderate power consumptions.

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.

Sickle profile

Multi-Wing’s sickle axial fan series is the answer for generating pressure with low noise axial fans.

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.
