- Understanding Battery Safety in Tool Development: When designing battery-powered tools, prioritizing battery safety is crucial. Firefighting PPV fans like the RAMFAN EX150Li 1.9 hp model or the smaller 0.9 hp EX50Li draw high currents (in amps) to maintain power, especially during their 30-45 minute runtime. To ensure safety, certain design measures are essential.
- Recognizing Heat Generation in Batteries: It’s a well-known fact in the battery industry that high discharge currents produce heat. However, for tools with short runtimes, like rescue tools (less than 30 seconds) or power tools (less than 5 seconds), heat buildup is minimal, and thus, special design considerations for heat management may not be necessary.
- The Risks of Overheating in Lithium-Ion Batteries: Lithium-ion batteries, commonly used in various applications, are sensitive to high temperatures. Overheating can lead to ignition, which is difficult to extinguish due to the battery’s internal fuel source. Therefore, it’s crucial to use batteries within their designated heat range.
- Understanding RAMFAN Battery Packs’ Heat Management Features:
- Cell Specification: RAMFAN’s R2 and M1 series battery packs, for PPV ventilation fans, use cells designed for a maximum continuous discharge current of 35A, ensuring a high safety margin. The Samsung 21700-40T cell is known for its high capacity and ultra-high discharge capabilities.

- Proprietary Battery Management System (BMS): Tailored specifically for each fan model, the BMS processes data from various sensors, including cell temperature, current, and voltage. This continuous monitoring ensures the battery remains within a safe operational zone.
- Heat Dissipation Design: The hard-anodized aluminum housing serves as a 360-degree heatsink, effectively dissipating heat to maintain ambient temperature levels.
- Choosing the Right Battery Pack: When selecting a battery pack, consider the specific demands of your equipment. Packs designed for other applications may not meet the unique requirements of tools like PPV fans. Always prioritize safety and suitability in your choice.

BrushlessPPV™
Motor
- Continuous Duty
- Greater than 90% efficiency
- TAEO Design
- Ultra lightweight
- Optimized for firefighting PPV use
RAMFAN has developed a range of high-performance brushless motor fans from 700W to 2.4kW, which we call our “BrushlessPPV” technology. We’ve leveraged our expertise in advanced power electronics to design a “power ladder” of choice for firefighters working with PPV equipment, based on the concept that higher voltage motors enable higher power output in a compact and lightweight package. Our singular mission is to develop the technologies necessary to replace high-performance petrol-driven fans with zero-emission alternatives.
Why does RAMFAN build its own brushless motors for first responders- what are the advantages?
Brushless electric motors are typically more efficient and lighter than conventional (brushed) motors due to several reasons:
- Improved Energy Efficiency: Brushless motors have less energy loss due to the lack of brush friction and improved heat dissipation, resulting in higher energy efficiency and longer battery life.
- Lightweight Construction: Brushless motors use permanent magnets instead of heavy copper windings in the rotor, making them lighter in weight.
- Better Control: Brushless motors can be precisely controlled using electronic speed controllers, leading to more efficient power usage and improved performance.
- Lower Maintenance: Brushless motors have fewer moving parts and do not require brush replacement, reducing maintenance costs and downtime.
- Higher Reliability: Brushless motors are less prone to wear and tear, leading to higher reliability and longer life.
Here’s another reason why RAMFAN is the most trusted brand by first responders for performance and safety. No other PPV fan company understands the rugged performance requirements of our emergency teams and builds the critical components, like brushless motors.
Electric brushless motors are made using several key components and manufacturing processes.
Here’s how our BrushlessPPV motors are assembled by RAMFAN engineers:
- Stator Core: The stator core is the stationary part of the motor and is typically made of laminated sheets of magnetic material, such as silicon steel. These sheets are stacked and bonded together to form the stator core.
- Stator Windings: Copper wire is wound around the stator teeth, which are projections on the stator core. The windings are typically arranged in a specific pattern, such as a star or delta configuration, depending on the motor design. The windings form electromagnets when an electric current flows through them.
- Rotor Assembly: The rotor is the rotating part of the motor and usually consists of permanent magnets mounted on a shaft. The magnets can be made of materials like neodymium, ferrite, or samarium cobalt. The rotor assembly is balanced and precision-machined to ensure smooth rotation.
- Hall Effect Sensors: In many brushless motors, Hall effect sensors are incorporated into the stator assembly. These sensors detect the position of the rotor magnets and provide feedback to the motor controller, enabling precise control of the motor’s speed and direction.
- Motor Housing: The stator assembly, rotor, and other components are housed within a protective enclosure made of materials like aluminum or plastic. The housing provides structural support, protects the internal components, and often includes mounting features for easy installation.
- Motor Controller: Brushless motors require a motor controller or drive electronics to control the flow of electric current to the stator windings. The controller receives input signals from various sources, such as Hall effect sensors or an external control system, and adjusts the timing and magnitude of the current supplied to the windings.
- Assembly: The various components, including the stator assembly, rotor, and motor controller, are carefully assembled according to the motor design specifications. Precision assembly techniques ensure proper alignment and efficient operation of the motor.
- Testing: Once the motor is assembled, it undergoes rigorous testing to ensure it meets the required performance specifications. Tests may include checks for electrical characteristics, mechanical integrity, temperature tolerance, and overall efficiency. Quality control measures are implemented to identify and address any manufacturing defects.
ADVANCED SAFETY FEATURES

AVAILABLE ON
40V and 52V BrushlessPPVTM Fans
Variable Input Power Management System
Key Features
- Variable Input Power Management System
- Maximize the performance based on available power source
- Auto detection of input power: battery & AC circuits
- Optimize for performance, safety & durability
Variable input power management (VIPM) maximizes performance of the fan based on the available power to the fan. Battery power is limited—powering a high-powered fan from a single battery doubles the discharge current required from that pack, increases cell temperatures, thus approaching or surpassing maximum current limits of cells. Spreading the load across two parallel packs allows fan performance to be increased.
115VAC circuits typically top out at 15A, or 1725W, while 230VAC allows more than double the power. Now one fan can automatically adjust its performance depending on the power available—simultaneously maximizing performance safety, and durability.
Rollover Protection System (ROPS)
Key Features
- Detect abrupt, unsafe fan movements
- Auto shutdown of fan to prevent injury
- Embedded sensor detection
- Safety technology built into all BrushlessPPV fans
The Rollover Protection System uses digital accelerometers embedded in the fan controller to automatically turn off the fan if it is abruptly knocked off its axis during operation. This ensures firefighters have both power and safety in a PPV fan when it is needed the most.
AVAILABLE ON EX, GX, WX Models
Key Features
