Add reliable airflow to compact cooling applications with the SPAL 30103018 4-Inch Low Profile Electric Puller Fan. Designed for applications where space is extremely limited, this compact 12-volt fan delivers approximately 147 CFM of airflow while maintaining a shallow profile. SPAL specifically positions this fan for smaller cooling applications where a conventional radiator fan would simply be too large.
The 30103018 is a puller-style fan, meaning it mounts behind the radiator, oil cooler, or other heat exchanger and draws air through the core. Its compact size makes it particularly well suited for engine oil coolers, transmission coolers, power-steering coolers, motorcycles, ATVs, and other auxiliary heat exchangers.
Featuring five paddle-style blades, a low-profile housing, and SPAL's purpose-built electric motor, the 30103018 provides a clean and dependable solution for adding forced airflow where natural airflow is limited or inconsistent.

Compact Cooling for Auxiliary Heat Exchangers
- The biggest advantage of the SPAL 30103018 is its extremely compact footprint. Large radiator fans are unnecessary—and often impossible to package—when cooling a small oil, transmission, or power-steering cooler.
- SPAL's 4-inch fan provides dedicated airflow directly through the heat exchanger, helping the cooler continue rejecting heat during idling, low-speed driving, staging, stop-and-go traffic, or other situations where natural airflow is reduced.
- Setrab USA specifically offers the 30103018 for pairing with its compact oil coolers and lists the fan at approximately 148 CFM at zero static pressure. SPAL/Holley documentation rates it at 147 CFM, which is the figure I would use for a retail listing.
Low-Profile Puller Design
- As a puller fan, the 30103018 should be positioned on the downstream side of the heat exchanger whenever the installation allows. When operating, it draws ambient air through the cooler and exhausts the heated air away from the core.
- Its low-profile construction makes it especially useful for installations where the cooler is positioned close to bodywork, suspension components, engine accessories, intercooler piping, or other equipment.
- SPAL's installation documentation lists the 30103018 at approximately 4.29 inches across the primary housing with a 2.38-inch dimensional depth in its fan-selection chart. Some distributor measurements differ depending on whether the motor, housing, or overall mounting envelope is being measured, so installers should use SPAL's dimensional drawing when verifying extremely tight clearances.
Ideal for Setrab Oil Cooler Systems
- The 30103018 is particularly popular for compact Setrab oil-cooler installations. Setrab USA specifically lists FAN30103018 as its 4.0-inch puller fan and provides compatibility information for adapting it to its fan shrouds.
- Adding a fan can be particularly beneficial when an oil cooler cannot be positioned directly in the vehicle's primary airflow path. Instead of relying entirely on vehicle speed to move air through the cooler, the SPAL fan provides active airflow whenever the cooling system requires it.
Installation Note
- The SPAL 30103018 is a universal fan, rather than a complete vehicle-specific cooling kit. Depending on the application, additional mounting brackets, shrouds, wiring, connectors, relays, switches, or controllers may be required.
- SPAL lists the fan at 3.4 amps, while its fan-selection documentation specifies a 4-amp recommended fuse at 13 volts. Electrical wiring and circuit protection should always be selected for the actual installation and according to SPAL's recommendations.
The SPAL 30103018 4" Low Profile Puller Fan is an excellent solution for customers who need reliable forced airflow in an exceptionally compact package, making it especially well suited to oil coolers, transmission coolers, power-steering coolers, motorcycles, powersports vehicles, and custom performance cooling systems.
