Fans for aviation technology from SEPA EUROPE
Aviation technology relies on thermal management as a key factor to ensure the safety and performance of aircraft. Modern aircraft are equipped with numerous electronic systems and components that generate a considerable amount of heat when they are in operation. Fans are essential components of active thermal management and contribute substantially to maintaining the temperatures within the safe operating limitations.

Electronics in the cockpit
The aircraft cockpit is equipped with central control, navigation and communication systems that all generate heat. If the heat is not effectively dissipated, system failures and potentially critical situations can be the result. Fans, therefore play a major role in ensuring that the operating temperature remains constant and likewise the stability of the aircraft systems.
The super light LY60B radial fan is particularly suited for the aircraft cockpit. It operates reliably where ample power is required yet space limited. The blower has a flow rate of 11m3 per hour and builds up 110 Pa pressure in extreme cases. It suctions in the air on both sides and is available in 5V and 12V. All models have a tacho output, the 5V version also has a PWM input.
Lightweight
As weight represents a critical factor in aviation, fans and other cooling systems have to be light and compact so that the overall weight of the aircraft is not significantly increased. It is therefore, vitally important to develop not only lightweight but also powerful fans.
In-flight entertainment
In-flight entertainment is an essential element of passenger flight experience and requires reliable yet low-noise thermal management. Fans play a decisive role in the cooling of sensitive components and their low-noise performance is essential for ensuring the comfort of the passengers. These fans must be efficient, durable and virtually noiseless when running. Airlines that place emphasis on optimum cooling and acoustic quality ensure both the functionality of their systems and the satisfaction of their customers.
The LF40P axial fan is one of SEPA EUROPE’s most popular fans and is ideally suited for providing reliable and quiet thermal management on board the aircraft. The new fan blades considerably improve the performance while maintaining the same noise level. The hub was deliberately kept as small as possible to avoid excess “dead space” in the centre and to aerodynamically optimize the longer rotor blades. The blades are elegantly curved with a cut at the ends. This cut prevents the blade from being hit by the air turbulence of the previous blade during rotation and in turn from achieving its own airflow performance.
When compared with the equally sized previous model a performance boost of 25% is achieved with the same noise level. Furthermore, the fan and the speed can be adapted to the required cooling performance via the PWM input which means that only as much noise as absolutely necessary is generated to operate the equipment reliably.
Low-noise level
Fans create noises that can be disturbing to passengers in the aircraft cabin. To assure a good level of acoustic comfort it is therefore important to develop low-noise fan technologies.
Ground Power Unit
In avionics the Ground Power Unit (GPU) is decisive for providing an aircraft with electrical power while it is on the ground. It maintains the necessary electrical power supply required for the aircraft systems to prevent the overload condition of the on-board power unit or engines. This is of vital importance during maintenance and boarding. The GPU supplies the avionics systems, lights, air conditioning and other electronic components with electricity. The cooling of the ground power unit is essential to ensure the service life of the electronic components, control electronics and the energy storage system as well as to maximize the operational safety. Without efficient cooling, the GPU can overheat which can result in both premature failures and affect the safety and reliability of the entire power supply while the aircraft is on the ground.
The KA1725HA2BMT-Mg axial fan is ideal for cooling the GPU. It is compact, powerful, reliable and has a wide operating temperature range. The housing and the rotor blades are manufactured from a magnesium alloy with good heat dissipation characteristics. The high-quality materials play a key role when it comes to durability and efficiency.
Reliable
Avionics cooling fans must be highly reliable to prevent a failure that could have severe consequences. High-quality materials and robust constructions plus regular maintenance are vital to ensure operational safety.
Customized solutions
The combination of heat sink and fan so-called active coolers can be seen as the key to success in accomplishing these tasks.Here SEPA EUROPE offers a wide range of individual components that can be combined in a variety of ways. This allows SEPA EUROPE to meet customer requirements in every respect.
Products for aviation technology
Axial fan with high performance MFB30G
With a very small size of 30 mm x 30 mm x 10 mm, the fan achieves a maximum air performance of 113 l/min. In addition, it offers maximum reliability due to 100% burn-in.
Radial fan LY60B05P
The fan is equipped with the durable and reliable Magfix® plain bearing. It offers a high flow rate of 185 l/min. Further advantages are the integrated reverse polarity and stall protection and the virtually vibration-free running behavior, which it achieves thanks to its low rotor weight and precision balancing.
The universal micro fan: MF17B
With minimal size (17x17x4.5 mm), this fan can be used as an axial fan and also as a radial fan. It is excellent for small battery-powered devices, has high shock and vibration resistance and is
Almost inaudible. For the compact dimensions it offers a high flow rate of 18 l/min.
