The SPAL EF3610 (VA18-BP70/LL-86S) is a commercial-grade, heavy-duty 16-inch performance electric cooling fan engineered specifically for 24-Volt electrical systems. Operating in a front-mounted pusher (blower) configuration, this high-output fan utilizes a specialized long-life motor and straight blades to force a massive 2204 CFM of air through thick, dense radiator cores in severe-duty environments.

Common Applications & What People Use It For

Because it is built for 24V architectures, the EF3610 is the industrial standard for heavy transport, commercial machinery, and specialized off-road builds across New Zealand and Australia:

• Heavy Transport & Trucks: Used as supplementary or primary cooling on commercial medium-to-heavy duty trucks running 24V systems.
• Agricultural & Earthmoving Equipment: Ideal for tractors, excavators, and loaders operating under continuous, high-load thermal stress in dusty conditions.
• 24V Off-Grid & Military Vehicles: Selected for custom overland rigs, military-surplus trucks, and heavy-duty safari setups requiring independent 24V electrical accessories.
• Large Industrial Heat Exchangers: Frequently paired with large industrial hydraulic oil coolers or remote-mount transmission coolers.
