A detailed technical guide to SPAL fans — brushed DC axial fans for 12V and 24V systems. Learn how they work, their key benefits (IP68 sealing, high airflow, quiet operation) and how to choose the right model.
Contents
SPAL fans are among the most recognised names in the world of cooling systems for vehicles and stationary applications. Italian manufacturer SPAL Automotive has been designing and producing fans, centrifugal blowers and coolant pumps for over 60 years, and its brushed DC axial fans are now an industry standard for reliable cooling of engines, radiators and condensers.
What are SPAL fans?
At their core, these are axial fans that move air parallel to the rotor's axis of rotation. SPAL builds them in 12 V and 24 V versions, with rotor diameters ranging from roughly 96 mm to 385 mm, covering everything from compact installations to powerful cooling for heavy machinery. They are driven by a brushed direct-current (DC) motor that delivers constant, efficient airflow with low energy consumption.
The full range of SPAL axial fans is available in our axial fans category, and you can browse all of this manufacturer's models on the SPAL Automotive brand page.
Key technical advantages
- IP68-sealed motor – the drive is protected against water and dust ingress, making SPAL fans reliable in harsh operating conditions.
- High, constant airflow – the compact blade design ensures powerful air movement at low noise levels.
- Quiet operation – optimised rotor geometry reduces aerodynamic noise, which matters for installation in vehicles and machinery.
- Long working life – every component is engineered for maximum efficiency and durability.
How to read a SPAL fan part number
SPAL uses a systematic nomenclature that starts with the VA prefix (axial fan), followed by alphanumeric codes for the series, airflow direction and diameter. For example, the SPAL VA69A-A101-87A is a 12 V axial fan, while models such as the SPAL VA53-BP70/LL-39A run on 24 V. The trailing "A" and "S" letters in the part number indicate the rotation direction and air intake/push configuration, so when replacing an original part it is important to select the exact matching version.
Sample performance data
According to the manufacturer, a reference model of around 280 mm diameter delivers airflow of up to roughly 208 m³/h at free flow, with static pressure up to about 245 Pa and a current draw in the order of 1.8–2.2 A. As SPAL notes, technical specifications are purely indicative and may change without prior notice, so the official datasheet of each model should always be used for accurate sizing. Complete technical specifications, performance diagrams and datasheets are available on the official SPAL website.
Where are SPAL fans used?
Thanks to their rugged construction, SPAL axial fans are used in cars and trucks, buses and coaches, agricultural and construction machinery, mobile refrigeration systems, and industrial and stationary applications. They most commonly cool engine radiators, air-conditioning condensers and heat exchangers.
How to choose the right model
When selecting a fan, consider the system voltage (12 V or 24 V), the required diameter and airflow, the airflow direction, and the available installation space. For replacing an original part, the safest approach is to match the part number. The range includes more affordable models such as the SPAL VA32-A101-62S 12V as well as more powerful versions like the SPAL VA33-BP91/LL-65A 24V for higher thermal loads.
Warranty and technical support
SPAL defines general warranty conditions and recommendations of use for its products (separately for brushed and brushless versions). You can find the current warranty terms on the official warranty conditions page.
Conclusion
SPAL fans combine Italian engineering heritage with modern cooling technology: IP68 protection, high airflow, quiet operation and a long service life make them a reliable choice for replacing original parts and upgrading cooling systems. The full range is available in our axial fans category.
