What is an axial fan anyway?
In axial fans, the air is sucked in and expelled again at an angle of 180° in the direction of the impeller’s axis of rotation. The impeller has a blade arrangement similar to an aircraft propeller. It is a simple and effective way to dissipate heat in electronic equipment.
Axial fans are used wherever high volume flows (air volumes) are required in conjunction with low pressures (resistances that have to be overcome).
At SEPA EUROPE you will find a wide range of axial fans.
New fan generation LF40P
One of the most popular SEPA EUROPE fans is the axial fan with the dimensions 40x40x10 mm and the popular Magfix® sleeve bearing. It underwent complete revision and further development. The new fan generation is known as the LF40P and the fan blades deliver significantly more power with the same level of noise.
The hub of the 40 mm model has been deliberately kept as small as possible which means that there is less „dead space“ in the centre and the longer rotor blades can be aerodynamically better optimized. The blades are elegantly shaped with a cut at the ends. The so-called „pressure gap“, provides the necessary compensation of the pressure ratios so that the performance of the otherwise relatively closely positioned rotor blades is optimized. In comparison with the previous model of the same size, 25% increase in performance can be observed with the same noise level. Furthermore the fan and the speed can be adapted to the required cooling capacity via the PWM so that only as much airflow noise is generated as is absolutely necessary to operate your device reliably.
Small axial fans by SEPA EUROPE – Cooling
concepts for limited designed spaces
With dimensions from 15x15x4.5mm to 20x20x8mm, flow rates of axial fans are between 0.6m³/h and 2.2m³/h.
In order for such a small fan to convey the optimum amount of air, we had to increase the speed, optimize the blade geometry and improve the inlet/outlet geometry. The optimum interaction of all relevant components enables power-saving operation.
Our smallest model MF15B05 measures 15x15x4.5 mm and weighs only approx. 1 g thanks to the housing and fan propeller that are made of vibration-reducing glass fibre reinforced plastic. This enables the mini fans to withstand adverse environmental conditions. The operating temperature is between -10°C and 80°C.
PLB60B – a powerful upgrade
Based on the axial fan series MFB60B that has been extremely successful for many years on the market, SEPA EUROPE is now presenting a powerful upgrade with its PLB60B series.
The fans of the PLB60B series, with the dimensions 60x60x15 mm have an optimized blade geometry that enables a maximum flow rate of 28 m³/h. The new SEPA fans set new standards in their class and are suitable for reliable CPU cooling in a broad range of applications.
The robust ball bearing system guarantees a long service life of 70.000 h L10 and 350.000 h MTBF at 40 °C and ensures a safe and smooth operation over many years.
The fail-safe axial fans are available in the operating voltages 5, 12 and 24. A PWM input with which the speed can be adjusted according to requirements is an available option.
RaAxial fan MF17B05
The fan and cooling specialist SEPA EUROPE unveils a true innovation this year: The RaAxial fan. This created term is a combination of the words radial and axial. The minifan with its dimensions of 17x17x4.5mm is ideal for compact, embedded applications and offers numerous possibilities.
E.g. as an axial fan for the ventilation of housings or as a radial fan for blowing air onto the heat sink. A tailor-made „Kühligel®“ has already been developed for the latter which makes the cooling of hotspots child’s play when space is limited.
Reliability has top priority at SEPA EUROPE. For this very reason the new fan is equipped with the tried and tested Magfix® bearing system. The life expectancy at 40 °C is 210 000 h (MTBF) or 40 000 h (L10).
HXB40FGK for efficient chip cooling
Inspired by customer inquiries, SEPA EUROPE has developed a new, modular assembly for the efficient cooling of chips. The core component is a SEPA axial fan that is mounted on a 40 mm pure aluminium heat sink – a so-called Kühligel®. It is equipped with a finger guard and a double-sided adhesive heat pad for screwless mounting on the housing or inside the device.
Thanks to the compact design, the light weight and the screwless mounting, this assembly enables accurate positioning and thus effective cooling of the hot spot. The chip cooler HXB40FGK is equipped with a high precision ball bearing and can be used at ambient temperatures between -10 and +85 °C thus opening up a wide range of application possibilities. A further advantage is the long service life of the fan with 350 000 h (MTBF) at 40°C.
The chip cooler assembly HXB40FGK is supplied as a standard component. It can however, be customized. Parameters, e.g. size, tacho output, PWM input, operating voltage or connector assembly, can be specially tailored by SEPA EUROPE to meet the requirements of the customers.
Compact, powerful and reliable – AC axial fan KA1725HA2BMT-Mg
SEPA EUROPE has the KA1725HA2BMT axial fan in its product range. This fan is specially designed for server rooms, computer centres and fast charging station.
It is compact, powerful and reliable and suitable for use at temperatures from -40°C to 85°C. The housing and the rotor blades are manufactured from a high-quality magnesium alloy that ensures that the induced self-heating is dissipated and the bearings are reliably cooled. High-quality materials play a key role in the durability and efficiency of a product.
The AC fans are available in the sizes 60 to 280 mm and have solid double ball bearings. In this SEPA EUROPE series naturally features the protection rating IP55.
When every millimetre counts: the frameless
axial fan AD0405
The AD0405 frameless axial fan impresses with its flat height of just 10 mm, making it ideal for applications with limited space.
Thanks to its open design, the axial fan can be integrated into heat sinks with a fin or pin structure and ensures optimum airflow directly at the heat source. It is available in 5V (AD0405), 12V (AD0412) and 24V (AD0424) and offers maximum flexibility for a wide range of electronic applications. The integrated PWM control enables whisper-quiet operation at low speeds, while the FG signal allows precise speed monitoring. The robust ball bearing guarantees a long service life even at constantly high ambient temperatures. The AD0405 is the ideal solution when a flat design, quiet operation and high reliability are required.
