Thermatic® Electric Fan Range

Davies Craig Thermatic® Electric Fans are available in sizes from 8" to 16", with 12V and 24V options across the range.

Note: Airflow figures are based on the Davies Craig published specifications. Always consider available space, system requirements and electrical capacity when selecting a fan.

---

What Size Electric Fan Do I Need?

Selecting the correct fan starts with the available space and the cooling requirements of your application.

Step 1 – Check the Fan Selection Guide

Use the Davies Craig Fan Selection Guide to search by vehicle make and model.

[FAN SELECTION GUIDE]

Step 2 – Measure Your Radiator

If your vehicle is not listed, measure:

• Radiator core width
• Radiator core height
• Available installation depth
• Clearance between the radiator and engine or surrounding components

Step 3 – Select the Largest Suitable Fan

As a general guide, one larger fan will normally provide greater airflow than two smaller fans. However, the shape of the radiator and available installation space may require multiple smaller fans.

Where two fans are required, select the largest combination that can be accommodated.

Fans should not be installed on opposite sides of the radiator core unless they are positioned so that the airflow from one fan does not interfere with the other.

Pusher or Puller?

Upstream (Pusher) or Downstream (Puller)

Davies Craig Thermatic^® Electric Fans can be configured to either push air through or pull air through the heat exchanger.

Upstream – Pusher

The fan is mounted in front of the radiator or heat exchanger and pushes air through the core.

This configuration is useful when there is limited space between the radiator and engine.

Downstream – Puller

The fan is mounted behind the radiator and pulls air through the core.

Where space permits, a downstream puller configuration can provide an efficient airflow arrangement and has less impact on frontal airflow at vehicle speed.

Factory Fan Configuration

Davies Craig Thermatic^® Fans are supplied in the upstream (pusher) configuration.

For downstream applications:

1. Remove the fan blade.
2. Turn the blade over.
3. Adjust the wiring as required.
4. Confirm the fan rotates in the direction indicated by the arrows on the blade.
5. Test the fan before permanently securing it to the radiator.

Always verify correct fan rotation before final installation.

Thermatic^® Fan Performance

Davies Craig Thermatic^® Fans are designed to provide controlled airflow regardless of vehicle speed.

As an add-on cooling source, electric fans can provide constant airflow across the radiator or A/C condenser, particularly when the vehicle is stationary or travelling at low speed.

When replacing a mechanical fan and fan clutch, an electric fan can also reduce the mechanical load associated with the original fan system.

---

Straight Blade Technology

Engineered for Efficient Airflow

Davies Craig has conducted extensive research into fan blade and shroud design, including comparisons between straight and curved blade designs.

Testing found that curved blades can generate less noise but may experience reduced performance at higher static pressure. Davies Craig's Thermatic® fan design uses straight blades with shaped shroud struts and blade-tip winglets to optimise airflow efficiency.

The result is a fan design engineered to provide effective airflow through the heat exchanger while maintaining efficient operation.

Straight vs Curved Fan Blades ~

Dispelling the Myth!

The relative merits and technology of curved vs. straight fan blades, has been debated for some time. Davies, Craig conducted an extensive research program to formulate the design of fans in which several design types including curved blades with and without a ring were considered. Curved blades generated less noise but at the expense of a significant loss in performance caused by the fact that curved blades stall at a lower static pressure than straight blades. If a fan moves less air, then, simply you can expect less noise. As shown in the performance curves below, Davies, Craig Thermatic Fan outperforms its competitor across the full pressure range:

 

   

Noise Control: Most fan noise is generated from a blade passing a shroud strut. The noise level is higher when the whole length of a blade overlaps/passes a shroud strut and if all the blades pass all the struts of a shroud at the same time, NOISE IS AT ITS WORST. Some manufacturers have chosen to curve the blades and keep the struts straight. Since this approach significantly affects performance, Davies, Craig has proven it's best to adopt the reverse approach of having straight blades and curving the struts.
Our investigations also found that when air flowed in layers (laminar flow), it breaks up into counter rotating airflow vortices (whirlwinds): Figure 2

 

These vortices consume energy and therefore reduce the airflow. It was found that by inserting triangular protrusions near the leading edge of the blade, the air is tripped into going into vortices earlier but they were much smaller and removed much less energy therefore making the blade more efficient (Figure 3).

 

The idea of a ring around the blade tips was also researched and rejected since the performance suffered due to the increased energy required to propel the blade with the extra weight at the tips. While the purpose of a ring is to reduce losses from air passing from the high-pressure side of the blade to the low-pressure side as shown, Davies, Craig managed to achieve this by adding winglets to the blade tips without energy loss.

When all aspects of blade design are considered, straight blades with tips, winglets and the correct shroud is the optimum, test-proven combination for efficient fan operation.
