SPAL VA82A-BBL375P/R/A/N-94A – 24V Brushless Cooling Fan with Electronic Control
The SPAL VA82A-BBL375P/R/A/N-94A is a 24V electric axial fan designed for cooling systems that demand controlled airflow and dependable operation. Featuring a 305mm impeller, integrated brushless motor electronics and an advanced control interface, this model offers a versatile solution for commercial vehicles, HVAC installations and specialist automotive cooling applications.
Operating at speeds up to 3,100 rpm, the SPAL VA82A-BBL375P/R/A/N-94A delivers approximately 2,700 m³/h of airflow under free-air conditions. The puller configuration is designed to draw air through radiators and heat exchangers, making it suitable for installations where the fan is positioned behind the cooling surface.
Intelligent motor control with PWM and feedback
One of the distinguishing features of the SPAL VA82A-BBL375P/R/A/N-94A is its electronic motor control interface. Rather than relying solely on fixed-speed switching, the integrated electronics allow the fan to respond to external control signals.
The motor supports PWM-based speed control and compatible analogue control signals. This enables airflow to be adjusted according to cooling requirements and allows integration into more advanced vehicle cooling systems.
The control interface also incorporates a feedback output for motor status information and an economy input for additional operating control.
Important control features include:
- Variable-speed operation using compatible PWM signals
- Support for analogue motor control
- Feedback output for status monitoring
- Additional economy control input
- Integration with suitable external cooling controllers
The motor must be operated with compatible control electronics following SPAL's electrical interface specifications.
Reliable forced airflow for commercial vehicles
Maintaining sufficient airflow through a radiator becomes particularly important when vehicles operate at low speeds, remain stationary for extended periods or experience high engine loads.
The VA82A-BBL375P/R/A/N-94A provides forced airflow through the cooling surface, supporting temperature management in a wide range of vehicle and equipment applications.
Potential applications include:
- Trucks and heavy commercial vehicles
- Buses and coaches
- Rally raid and specialist off-road vehicles
- 24V engine cooling systems
- Vehicle air conditioning and HVAC systems
- Industrial equipment and heat exchangers
- Custom vehicle cooling installations
Actual airflow depends on the static pressure resistance of the radiator or heat exchanger. The manufacturer's performance curve should be considered when determining suitability for a particular cooling system.
