C-serien


D-serien

D-Serien

The D series covers diameters from 360mm up to 660mm. The relatively small diameter and the broad, paddle-shaped profle of the fan blades makes the D series ideal for smaller heat exchanger applications such as oil coolers, air-cooled condensers and dry coolers. With fan blades of glass reinforced polyamide it can be used in low temperature evaporator applications as well.

The D series provides a successful combination of high airfow and high-pressure rates at low speeds and produces low noise levels. The fact that its made up of a modest number of components makes it highly cost-effcient.

G-serien

G-Serien

The G series is the perfect solution for larger applications that require high effciency, high-volume airfow and low noise. The series has a diameter range of 13002746 millimeters and features two of our most popular impellers: the 10G airfoil and the 1G sickle.

Our G series sickle impellers generate more pressure while reducing noise, and our G airfoil design saves horsepower while generating high-volume airfow for optimum effciency. The spectrum of G series impellers is ideal for applications ranging from industrial heat exchangers to HVACR.

H-serien

H-SerienThe H series covers diameters from 225 mm up to 742 mm. As with all Multi-Wing impellers, the H series is designed to have high efficiency and low noise level and to be corrosion resistant. It is robust yet light-weight resulting in less wear and stress on motors and bearings.

Its compact but solid design is well suited for a variety of applications. For engine and compressor cooling this impeller type offers a flexible solution that will meet all dimensioning criteria - especially when noise levels are critical. Type H is also applicable to agricultural ventilation, which calls for high performance at low static pressure. For cooling applications, this type is often used in evaporators and in smaller condensers.

Z-serien

Z-Serien

The Z series is one of our broadest series; therefore it can be used in just about any air moving application. It covers diameters from 225 mm to 1261 mm. As with all Multi-Wing impellers, the Z series is designed to have high efficiency and low noise level and to be corrosion resistant. It is robust yet light-weight resulting in less wear and stress on motors and bearings.

The Z series is widely used in the ventilation and cooling industry as well as in automotive applications where environmental requirements are more demanding. It also offers a suitable solution in applications that demand high performance in difficult flow conditions, where there is less focus on power consumption. The Z series also features reversible impellers designed specifically for drying applications.
