History lingers - we still use fans designed in 1920

People have been moving air since the dawn of time. At the start of the 20th century, sustained heavier-than-air flight became a reality. While the aircraft industry drove the development of modern aerodynamic principles, fans have fallen well behind. Suppliers could convince their customers that their fans were efficient, the fans were cheap to manufacture, performance was good enough and power prices were low.

Energy efficiency and lifetime costs are now KPI's for high performing fan operators, and the people paying for power now have more input to the design, specification and purchasing process.

The aerodynamic engineering of currently installed and market-leading new product offerings is historically powerfully price driven, to the exclusion of significant efficiency potential - which in a stable electricity sector without price volatility made good sense. The energy market has changed significantly in NZ (and worldwide) in the last 5 to 10 years - and this pace of change isn’t slowing. Legacy equipment has generally been installed with a 10 to 20 year service life expectancy and the main supply options in the 800mm to 1800mm diameter sector (7.5-40kW) have remained largely unchanged for decades, in a race to the bottom for installation price.


the solution: 21st century design

The range of AerotekFan fans have been specifically designed with modern aerodynamic and manufacturing principles. The result, a cost-effective highly efficient fan design that can immediately start saving you money.


INDUSTRY standards

Our existing products are designed for adverse environmental and loading conditions. Once we complete design refinement based on ongoing lab and field evaluation, we will begin licensing and certification against AMCA and other industry standards.



Total cost of ownership is further reduced, as our fans are designed for use as new built, or easily retrofitted to existing assets. These fans are supplied balanced, vibration and performance validated and ready to fit as adaptive drop-in replacements for a variety of hub/blade/duct setups.


reduced motor sizes

New builds can achieve comparable airflow performance and potentially drop motor sizes by more than 30% (e.g. reduce motor size from 11kW to 7.5kW), a significant saving in asset costs. Reduced weight and noise mean fixed assets will have higher reliability and reduced need for unscheduled maintenance, potentially leading to extended asset replacement cycles.



Our low cost web based, mobile optimised airflow and condition monitoring system measures airflow, pressure, vibration, temperature, humidity, and power. It allows maintenance to be scheduled when problems are detected, such as bearing failures, fan or hub imbalances, airflow, power quality or pressure issues.

Superior design

Our products’ superior design offers significant power reduction potential without loss of performance AND our exclusive production process enables a ROI of less than 2 years.
