SRTVAUTC 10″ Radiator Fan – Slim Pull/Push 24V
The SRTVAUTC 10″ radiator fan delivers high-performance cooling with 24V operation and a compact 2.36-inch thickness. It features 6 blades and a maximum airflow of 800 CFM at up to 2400 RPM (±10%). The fan draws 5-7 amps and outputs about 80W, making it suitable for cooling radiators, A/C systems, intercoolers, and transmission oil circuits. The unit is designed for flexible installation with a reversible push-pull configuration; blades can be flipped, and wiring reversed to switch air direction. Ideal for tight engine bays needing strong cooling without bulk.
Radiator Fan 24V 16in Slim – Naroote
Designed for broader engine bays, this 16-inch 24V slim fan by Naroote uses 10 blades to maximize airflow at up to 2250 RPM and 120W. It supports full engine-compartment cooling, including radiators, AC systems, and oil circuits, while maintaining relatively low noise. The ultra-slim profile helps installation in tight spaces without sacrificing cooling efficiency, making it a solid choice for trucks, RVs, and trailers requiring robust air movement through the radiator core.
LSSOCH 24V Electric Cooling Radiator Fan Blower
The LSSOCH unit is a 24V radiator fan blower listed as 30100465 and is designed to be compatible with SPAL VA09-BP12/C-54A models. It provides a straightforward match for SPAL-based cooling systems and is positioned as a compatible replacement or upgrade. This option emphasizes compatibility with established SPAL configurations, simplifying installation in vehicles that use these standard valve assemblies while offering reliable 24V operation.
14 Inch Slim Electric Radiator Fan – Wepeculior
Wepeculior offers a 14-inch 24V radiator cooling fan with an 80W rating and a slim profile designed for engine bay clearance. The unit claims 24V operation with 50-80W typical draw and supports cooling the radiator, A/C condenser, intercooler, oil system, and transmission. Its universal slim construction is meant to fit a wide range of vehicles while maintaining solid airflow to prevent overheating in cramped compartments.
SRTVAUTC 12″ Slim Radiator Fan
The 12-inch SRTVAUTC fan features a slim 2.56-inch thickness with 10 blades designed to deliver substantial airflow. It operates on 24V and provides 80W of power with an approximate 5-7 amp draw. Similar to the 10-inch model, it supports push-pull configuration, enabling flexible installation and airflow direction. This option suits installations requiring higher CFM in a mid-sized footprint for robust radiator cooling and related systems.
Buying Guide: Key Considerations for 24V Radiator Fans
- Airflow capacity (CFM): Match CFM to radiator size and vehicle demands. Higher CFM improves cooling under heavy loads but may increase noise.
- Voltage and power draw: Ensure your vehicle’s electrical system can handle the fan’s 24V operation and amperage requirements (typically 5–7A for these models).
- Physical size and mounting: Slim designs save space in tight engine bays; verify thickness and overall dimensions to avoid clearance issues.
- Push-pull flexibility: Reversible blades or wiring allow adaptable airflow direction without multiple units, beneficial for dual-radiator setups.
- Compatibility: Some fans are designed as direct replacements or SPAL-compatible units; check compatibility with your radiator, A/C condenser, intercooler, and trans cooler.
- Durability and materials: Look for corrosion-resistant housing and blade materials suitable for automotive environments and heat exposure.
- Noise level: Consider the noise profile, especially for daily drivers or quiet environments; higher RPM fans may produce more sound at peak operation.
- Sensor and control options: Some fans pair with thermal switches or fan controllers to optimize operation based on coolant temperature.
When selecting a 24V radiator fan, balance airflow needs with space constraints and electrical capacity. For compact engine bays, slim 10–12 inch fans offer strong cooling with minimal intrusion. For larger radiators or higher-demand systems, 14–16 inch models provide greater airflow at potentially higher power usage. Reversible/push-pull designs deliver installation flexibility, especially in multi-component cooling systems. Finally, verify compatibility with existing components, especially SPAL-based or OEM configurations, to ensure reliable performance and ease of replacement.
