Inside the G Series: Modular, powerful, and built for Africa

When airflow demands are large, continuous, and mission-critical, the Multi-Wing G Series delivers. Designed to handle the toughest climates and operating conditions, this modular axial impeller system offers unmatched size, precision, and flexibility.

Why choose the G Series?

Purpose-built for large-scale applications, the G Series combines aerodynamic efficiency with fine-tuned control:

• High airflow efficiency – Moves large volumes of air at low to medium static pressure with reduced energy input.

• Fine pitch adjustment – Tunable in precise 1° increments between 15° and 50° for performance optimisation.

• Robust modularity – Replace blades, hubs, or inserts without removing the whole fan.

• All-weather durability – Injection-moulded from polyamide glass-filled nylon with carbon black to withstand harsh UV exposure, high temperatures, corrosion, dust, and humidity.

• Direct-drive ready – Supports high tip speeds without the need for a gearbox thanks to its robust mechanical design. Pairs directly with a motor and variable speed drive for efficiency and low maintenance.

This makes the G Series ideal for engineers and operators who need powerful performance without compromising serviceability or system design.

Built for Africa’s big jobs

With diameters ranging from 980 mm to 3 500 mm, the G Series is the largest in the Multi-Wing range. It’s engineered for use in high-demand sectors such as:

• Cooling towers – Essential in mining, power generation, and heavy industry.

• Central HVAC systems – For malls, airports, and data centres.

• Generator and engine cooling – Especially in off-grid or remote installations.

• Evaporative condensers and heat exchangers – In refrigeration and chemical processing.

• Tunnel and infrastructure ventilation – Reliable airflow in public transport and utilities.
