Inside the robust Multi-Wing G Series fans
19 September 2025
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 3,600 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.
