300W Brushless Surface Mount Cooling for 15-Inch Shroud Builds
The SPAL SPL30107125-PKG is a 300-watt brushless puller fan in a 15.2-inch flush mount configuration, delivering variable-speed cooling that sits on top of the shroud surface rather than recessing inside it. Producing 1,765 peak CFM with an IP68 and IP6K9K sealed motor, SPL30107125-PKG is ideal for installations where shroud depth is limited but a large fan diameter is needed to cover the radiator core. The included jumper harness enables straightforward integration with the SPAL Plus Series sensor system.
Key Features
- 300-watt brushless motor with automatic variable-speed control, approximately 25 amps at peak
- 1,765 peak CFM airflow at maximum operating temperature
- 15.2-inch diameter, flush mount style sits on top of the shroud surface
- IP68 and IP6K9K sealed motor for water submersion and high-pressure spray protection
- Includes jumper harness for SPAL Plus Series sensor system integration
- Curved blade design for efficient cooling at variable speeds
- Integrated EMC filters and built-in electrical protection
- Requires SPAL Plus Series temperature sensor and SBL-YAZ-PT10 pigtail harness (sold separately)

Frequently Asked Questions
What is the difference between the 300W 15.2-inch flush mount and the 500W 15.2-inch flush mount?The SPL30107125-PKG produces 1,765 CFM and draws approximately 25 amps at peak. The 500W version (SPL30107328-PKG) produces 2,432 CFM and draws approximately 41.67 amps. Choose the 300W model for stock-electrical vehicles and the 500W model for builds with high-output alternators or significant thermal demands.
What temperature sensor is compatible with the SPL30107125-PKG?A SPAL Plus Series temperature sensor is required, such as the SBL-TS-165P (140F to 165F), SBL-TS-185P, SBL-TS-195P, or SBL-TS-215P. Choose based on your coolant operating temperature. All sensors are sold separately.
What additional harnesses are needed for the SPAL 300W 15.2-inch flush mount fan?You need the SBL-YAZ-PT10 pigtail harness (plugs into the fan connector) and the SBL-TS-HARN harness (connects sensor to pigtail). Both are sold separately and required in addition to the included jumper harness for a complete installation.
Why would I choose a flush mount fan over a drop-in model?Flush mount fans are the correct choice when the space between your radiator and engine components is too shallow for a drop-in style fan to recess inside the shroud. They mount flat to the shroud surface and require no additional depth behind the shroud face, making them well-suited for tight engine bays.
Can the SPL30107125-PKG replace a factory dual-speed electric fan?The SPAL Plus Series uses a different control system than factory two-speed fans and requires the dedicated sensor and harness kit. While the airflow output is comparable to or greater than many factory fans, you must install the SPAL sensor and harness to control the brushless motor properly.
Is a custom shroud required to mount the SPAL 15.2-inch flush fan?Yes, a shroud with a 15.2-inch fan opening is required. The fan mounts to the front face of the shroud using its integral mounting tabs. Universal shroud kits and custom shroud fabrication are common approaches for installing this fan.
What fuse and wire gauge should I use for the 300W 15.2-inch flush mount fan?Use 10-gauge wire for power and ground, with a 30-amp inline fuse positioned close to the battery. This provides appropriate overcurrent protection for the fan's 25-amp peak draw and ensures the circuit is protected from short-circuit faults.
Does SPAL warrant the Plus Series brushless fans?SPAL provides a manufacturer warranty covering defects in materials and workmanship for the Plus Series brushless fans. Warranty terms vary by region. Contact your authorized SPAL dealer or distributor for specific warranty details applicable to your purchase.
Installation Instructions
- Confirm the shroud has a 15.2-inch opening on its mounting surface for the flush mount fan.
- Position the fan on the shroud surface with the motor facing away from the radiator.
- Mark and drill mounting holes per the fan's tab pattern and secure with appropriate hardware.
- Connect the SBL-YAZ-PT10 pigtail harness to the fan connector.
- Attach the SBL-TS-HARN harness between the pigtail and the temperature sensor.
- Thread the temperature sensor into a 3/8-inch NPT port in the radiator or inline cooling fitting.
- Route and secure all wiring away from heat sources and moving components.
- Run power and ground in 10-gauge wire with a 30-amp inline fuse near the battery.
- Warm the engine to operating temperature and verify the fan cycles on correctly.
- Inspect fasteners and wiring after the first heat cycle and test drive.
