SPAL 500W 16in Drop-In Brushless Fan w/Jumper Harness

500 Watts of Brushless Cooling Power in a 16-Inch Drop-In Package

The SPAL SPL30107101-PKG is a 500-watt brushless electric puller fan built for high-demand cooling applications where maximum airflow and long-term reliability are non-negotiable. At 16 inches in diameter and 2,430 peak CFM, this drop-in style fan integrates directly into a custom shroud and delivers variable-speed control through the included jumper harness, automatically ramping up as coolant temperature climbs. The IP68 and IP6K9K sealed motor withstands full water immersion and high-pressure washing, making SPL30107101-PKG a lasting upgrade for race builds, heavy tow rigs, or high-performance street cars.

About SPAL

SPAL Automotive has been engineering high-performance electric fans for OEM and aftermarket applications since 1959. Based in Italy with manufacturing operations worldwide, SPAL supplies cooling solutions to automotive, motorsport, and industrial markets across the globe. The Plus Series brushless fan line represents SPAL's most advanced offering for custom cooling builds, combining sealed motor technology with variable-speed control for efficiency and reliability unmatched by conventional brushed fans.

Frequently Asked Questions

This fan requires one of the SPAL Plus Series temperature sensors such as the SBL-TS-165P (140F off, 165F on), SBL-TS-185P, SBL-TS-195P, or SBL-TS-215P depending on your cooling system target temperature. The sensor is sold separately.

You need the SBL-YAZ-PT10 pigtail harness that plugs directly into the fan connector, and the SBL-TS-HARN harness to connect your temperature sensor to the SBL-YAZ-PT10. Both are required for each fan and are sold separately.

A drop-in fan (like the SPL30107101-PKG) sits partially inside the shroud, so the shroud must have enough depth between the radiator and motor to accommodate the fan body. A flush mount fan sits on top of the shroud surface and does not require shroud depth clearance.

The fan speed adjusts automatically based on coolant temperature as read by the SPAL Plus Series temperature sensor. At lower temperatures the fan runs slower, reducing parasitic electrical load. As temperature rises toward the sensor's on-threshold, fan speed increases to its peak. The blue override wire allows you to run the fan at full speed regardless of temperature when wired to a manual switch.

No. The Plus Series fans require the Plus Series temperature sensors (SBL-TS-XXP suffix models). The older Nuova series sensors and harnesses are not compatible with the Plus Series fan connector.

At peak output on a 12V system, the 500W motor draws approximately 41.67 amps (500W divided by 12V). Always size your wiring, fuse, and relay appropriately for this current draw to ensure safe operation.

Each SPAL Plus Series brushless fan requires its own SBL-YAZ-PT10 pigtail harness. Multiple fans can share a single temperature sensor by splitting the sensor signal, but each fan needs its own dedicated pigtail connection.

Yes. Drop-in style brushless fans are designed for use inside a custom or semi-custom shroud that provides proper clearance between the radiator core and fan motor. The shroud depth must accommodate the fan's 3.20-inch depth. Universal mounting adapters and shroud kits are available from SPAL and aftermarket suppliers.

Installation Instructions

1. Measure the available shroud depth between the radiator core and any obstacles to confirm 3.20 inches of clearance for the fan body.
2. Position the fan in the shroud opening with the motor facing away from the radiator (puller configuration).
3. Secure the fan to the shroud using appropriate mounting hardware for your shroud design.
4. Connect the SBL-YAZ-PT10 pigtail harness to the fan's connector.
5. Connect the SBL-TS-HARN harness between the pigtail and your temperature sensor.
6. Install the temperature sensor in a 3/8-inch NPT threaded port in your radiator or cooling system fitting.
7. Route and secure all wiring away from heat sources and moving parts.
8. Connect power and ground using appropriately sized wire and a fuse rated for at least 50 amps.
9. Test operation by allowing the engine to reach operating temperature and verify fan activates at the correct temperature threshold.
10. Confirm all connections are secure and no wiring contacts hot or rotating components.
