Increasing arc axial fans
High Performance l High Static Pressure l Corrosion Proof l Robust l Light Weight l Fit for Inlet Conditions
Multi-Wing’s Increasing Arc blade profile ensures high performance in space-restricted inlet conditions. The fan is half the weight of steel and its lower moment of inertia reduces wear on drive components. The broad tip area of the increasing arc improves fan performance in applications where space restrictions make inlet conditions less than ideal.
The available diameter range is 222-1255mm (8.7-49.5 inches). Our Increasing Arc blade is suitable for compressors, generators, construction machines, cranes and chassis.
Effective Upgrade to Any Fan l Increased Efficiency l Minimalized Turbulence l Easy Maintenance l Lowers Noise
Multi-Wing ePS™ is a highly efficient upgrade to any custom-made axial fan. Multi-Wing ePS are special bristles attached at the end of the blade. ePS ensures closure of the boundary between a shroud and a fan, triggers minimal turbulence, offers smooth motion, lower noise, higher efficiency and pressure performance. Our bristles are easy to maintain, improve pressure capabilities up to 25%, boost efficiency up to 8% points and reduce noise emissions. Multi-Wing ePS bristles enhance performance in any application.
High chemical resistance verified by third-party testing
Bristles provide high mechanical and chemical resistance allowing for a multitude of uses in various industries and applications. They can endure temperatures up to 120 °C (248 °F). Static strength tests show that Multi-Wing ePS can withstand loads of more than 40N/mm, allowing for the usual maximum operating speed of PAG fans, which are used especially in the most demanding environments, such as off-road applications. Fatigue testing proves that performance and noise remain unchanged and maintain optimal performance levels even after 400,000 impacts. The chemical resistance test performed by a third party institute shows no damage to the Multi-Wing ePS when exposed to hydraulic oil, diesel fuel, coolant, as well as R134a refrigerant and lubricant.
MxFlo mixed flow fans
50% Higher Static Pressure l Peak Efficiency at Higher Pressure l Narrow Blade Profile l Clutches Fit l Tier 4F, Tier 5 and Stage V Compliant l Optimises Performance l Less Fuel Consumption
Multi-Wing’s custom MxFlo Mixed Flow fan achieves peak performance at higher pressures, optimises fuel consumption and provides ideal airflow, thereby reducing turbulence and increasing efficiency.
The MxFlo is designed to be used with clutches and combines axial and radial air flow for engine cooling. It consists of nine fan blades and one hub - all cast in polyamide-reinforced glass, which results in less wear and tear on motors and bearings.
MxFlo fans feature narrow blade profile optimally suited for fitting into tight engine compartments commonly used in off-road Tier 4F, Tier 5 and Stage V applications. MxFlo fans are available in diameter of 550-735mm (21.6-29 inches) and different pitch angles.

True reversible axial fans
High Efficiency & Pressure l Reversible Configuration l Equal Airflow in Both Directions l Low Noise l Cost Effective l Up to 74% More Efficiency
Multi-Wing’s True Reversible blade profile provides up to 74% more efficiency thanks to its reversible configuration, which allows for even airflow in both directions. The True Reversible blade performs well in high efficiency, high pressure and low noise, and still remains a cost-effective alternative. The available diameter range is 325-1606mm (13-63 inches). It can be used in drying kilns, tunnel ventilation, brick drying and other applications.
Add-on to the Tip of the Blade l Next Level of Low Noise Solutions l Effective Fan Upgrade l Impressive Reduction of Sound l Cost Saving
The winglet is a highly effective addition to the best axial fan technology. They reduce noise by up to 7dBA as the leakage of the air through the tip clearance is prevented and blade tip vortexes are minimized. Winglets are thermoplastic add-ons that are riveted to the top of each blade. The riveted attachment solution is very strong and maintains the temperature range of the blade material. Winglets are designed for industrial cooling applications in the middle pressure HVAC segment, such as condensers, flatbed coolers, and V-coolers, and offer standard fan design flexibility and cost savings. Our next level of low noise solutions has been designed specifically for 1W fan blades, but they could be modified to fit other blade profiles. The blades are available in a variety of materials.
Our Winglets are designed for pitches ranging from 40 to 50 degrees, and they can be mounted on impellers within diameter range 850mm to 1340mm. They are applicable in Bellmouth inlet. The data are available in Optimiser selection software.
