Axial fans - Import export

In the fluid dynamics laboratory of our Wasserburg competence centre, we design new fan wheels and turbines and optimise existing systems for performance, energy efficiency and noise emissions. We also develop complete systems of wheels with power units. Our range of tests includes suction operation, pressure operation and also unpressurised measurements. Revolutions up to 40,000 r/min and diameters of up to 250mm are possible. In our prototype department, we are able to simulate or modify the environmental circumstances of the fan wheels or turbines, thus achieving optimal operational conditions. Furthermore, we carry out mould-flow analysis, use ANSYS from external partners for the flow simulation and establish the fault probability and fault effect with FPFEs. New: Development of blower systems and optimization of ventilation systems.

ATEX fans are fans that are installed in environments where there is a risk that an explosive atmosphere can form. Therefore, these fans need to be designed according to the ATEX directives. Depending on the classification of the environment, internal solutions inside the fan, such as e.g. spark protection in the fan cover or non-sparking materials. While in other cases, EX-rated motors are also required. Explosive gases require special fans. Our factories are certified according to ATEX for the manufacture of fans for Zone 1 and 2 as well as for Zone 21 and 22 containing dust. The design, production and use of fans for explosive media or environment is clearly specified in Europe by standardized directives. To choose the right ATEX fan, one should start from operating data and process design, as well as whether there are any special requirements.

A roof fan can be the same name referring to two different types of fans. On the one hand, it is the classic fan that is mounted indoors in homes and spins around to create an air flow in a room (these are also called HVLS fans (High-Volume Low-Speed)). And partly it is the type of fans that we work with – i.e. fans that are mounted outdoors on roofs belonging to e.g. apartment buildings, schools or industrial premises. A roof fan is a fan that is part of the ventilation system and has the task of extracting hot air, moisture and pollution from the indoor space and blowing them outside. The fans are usually designed to be robust and weather resistant as they are mounted on the roof. Of course, there are a variety of material designs adapted to the application needs.

Renewable energy sources are something that is becoming more relevant every day. Biogas is an alternative and here FläktComp Sweden can contribute with high-quality fans that ensure that the biogas is handled correctly. Biogas fans are a type of gas-tight radial fan, adapted for use in biogas environments where the demands on materials and performance are very high. The fans are usually delivered as a complete unit consisting of fan wheel, motor, cover and vibration feet. In order to choose the right biogas fan, one should start from operating data and process design, as well as whether there are any special requirements.

Axial fans are a type of fan that creates airflow through a fan wheel that rotates around an axis and moves the air parallel to the axis. Axial fans can also be called propeller fans and are usually delivered as a complete unit consisting of fan wheel, motor and cover. Typically axial fans are direct driven with the impeller mounted on the motor shaft. There are also other designs such as e.g. belt-driven or with shaft bearing and coupling. The axial fan’s strength is to transport large volume flows at low pressures. At higher pressures, a centrifugal fan may be a better choice. To reach higher pressures with axial fans, these can be connected in series. Usually, the efficiency of an axial fan is comparatively lower than that of a centrifugal fan. But by using guide rails, diffusers and other accessories, an axial fan can reach the same or higher efficiency. The flow of axial fans can be regulated with vane or damper or speed regulation.

High flow wall fans for extraction and/or ventilation This type of fans provide significant air flows for the extraction and/or ventilation of industrial, livestock or agricultural premises. Main features - Air flow from 21,000 m3/h to 39,800 m3/h - Structure and overpressure slats in galvanized steel to avoid premature corrosion. - Propellers made of AISI 430 BA stainless steel. - High quality bearings. - IP-55 three-phase electric motor - V-belts. - Transmission pulleys made of magnesium aluminum. - Engine support with tensioner. - Side inserts for easy transport.

For large quantities of air with a low pressing force. Axial fans Axial fans are used wherever large quantities of air need to be moved with a low pressing force. They are frequently used for the aeration and ventilation of rooms. Axial fans can also be used for the cooling of rotary kilns in cement works.

The chip cooler of the HXB series by SEPA EUROPE is a compact combination of fan and heat sink and is an attractively priced combination with an adequate cooling capacity. But the development engineers at SEPA EUROPE wanted to go further and this pushing ahead marked the birth of the 3DQler. The cooperation with the experts of APWORKS provided the decisive impulse. Due to the metal 3D printing, also known as additive manufacturing, APWORKS is in the position to produce geometrically highly complex heat sinks. Without having to change the external dimensions or make the fan more powerful, the additively manufactured version can be realized with 30% more efficient waste heat. With the 3DQler, SEPA EUROPE and APWORKS have developed a modern and active cooling concept that offers numerous advantages: Freedom of design with regard to installation space and a reduction of the manufacturing costs.

As the need for fans that are used in applications subject to high temperatures is constantly on the increase, SEPA EUROPE is presenting its latest sleeve bearing fan equipped with MagFix technology that can be used for operating temperatures up to 85 °C. An added advantage is the extraordinary high life expectancy of 210.000 h (MTBF). This fan is not only available in the standard sizes but also as a tailor-made solution. With the high operating temperature of up to 85 °C, this innovative fan generation by SEPA EUROPE opens up a wide range of new applications for the user, not least the automotive sector. The term MagFix stands for magnetic fixation (positioning) of the fan propeller/rotor in sleeve bearing fans.

Serie LPE HELICAL FANS FOR WALL The LPE serie’s fans, present constructive characteristics that allow both the utilization in the industrial applications and the installations in the tertiary environments (workshops, stores, breedings, glasshouses) where there is the real necessity of the employment of a fan with easy installation, low consumptions, and reduced noise pressure levels.

Even the micro fan MF17B05 from the RaAxial range was a true innovation simply because it can be used not only as an axial fan but also as a radial fan. The micro fan has now a „big brother“– the LF40E05. The LF40E05 provides numerous possibilities for embedded applications. It can be used either as an axial fan with integrated finger guard or as a radial fan in combination with a heat sink. Together with a matching Kühligel® the flat cooling units have a height of approx. 12 mm. In other words, they are ideal for compact applications. In order to achieve the optimum size and heat dissipation, customized dimensions and shapes can be realized. The new model with its 0.15 W power input during operation, is extremely economical with regard to its diverse application possibilities. And that’s not all, the new RaAxial fan has aerodynamically optimized blades that have a significant effect on the noise behaviour. The LF40E05 is thus exceptionally quiet.

The fan and cooling specialist SEPA EUROPE has now added three further models to its slimline radial fan series. The latest additions impress with their compact dimensions of 38 x 40 x 5 mm, 54 x 52 x 6 mm and 45 x 45 x 4 mm and have more than deserved the name „slimline“. All fans are equipped with the reliable Magfix sleeve bearings and have a service life of 210 000 h (MTBF) and 40 000 h /L10) at 40 °C. The PWM input in combination with the tacho output enables the speed to be controlled and monitored. It is not obvious at first glance, but the Model HY45AB05PNK00A tops with a pressure of 143 Pa. The new models will be included in the standard range and will therefore be available shortly from stock. SEPA EUROPE specializes in customized cooling solutions. Thanks to over 25 years of experience, SEPA EUROPE can offer you the appropriate solution for virtually every task.

The significance of air quality measurements whether in industry, households or in vehicles is constantly increasing. Manufacturers therefore, should equip their applications with the optimal sensor fan and in this respect SEPA EUROPE is exactly the right partner! SEPA EUROPE has complemented its range of microfans with the radial fan HY20A with the dimensions of 20 x 20 x 6.3 mm. The air intake of the radial fan which is on one side is 2 l/min and with a sound pressure level of 5dB(A) at a distance of 1m, it is virtually inaudible. As is the case with all microfans, the HY20A is equipped with the reliable Magfix sleeve bearing and has a service life of 400 000 h (MTBF) or 50 000 h (L10) at 40°C. The tachometer output constantly monitors the speed at which the fan is running. The HY20A is also an interesting solution for the cooling of hot spots in embedded applications. This compact blower ensures that optimal use is made of limited installation space.

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.

One of the most popular SEPA EUROPE fans is the axial fan with the dimensions 40x40x10 mm and the popular Magfix® sleeve bearing. This year it underwent complete revision and further development. The new fan generation is known as the LF40P and with the same external dimensions is installed in the same way as the previous model. The new and currently unique rotor geometry is obvious at first sight. It is completely different from the previous shape and layout. Thanks to the distinctive rotor blade with a cut, either a clear noise reduction can be achieved at the same speed or the same noise level as previous generations with 25% more air performance. The current model is equipped with the SEPA MagFix® bearing and PWM input with which the speed can be set to meet the necessary requirements. The LF40P is an excellent example for the permanent further development of products at SEPA EUROPE.

The new super flat active chip cooler of the cooling specialist SEPA EUROPE is a convincing solution for applications in the embedded computing sector, in particular for single board computers. The HZ25B05 with its dimensions of 25x25x6.5 mm can be installed even in flat applications and ensures highly effective heat dissipation. The size of this super flat design is not its only advantage, but also its exceptionally low noise level. The heat sink is made of high-purity aluminium and has low thermal resistance. The integrated micro fan is also equipped with a special, highly durable MagFix® sleeve bearing designed for operating temperatures of up to 80°C. Particularly noteworthy is the fact that the micro fan which is operated with a voltage of 5VDC, has a power input of only 0.3 W and a life expectancy of 400000 hours. The fan can also be equipped, if necessary, with a tacho output for monitoring the function. Both and the fan and the heat sink are available separately.

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 microfan 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).

By mounting an axial fan, the effectiveness of the new Kühligel® can be increased considerably. Fanless solutions require a lot of space. They are heavy and expensive. For cooling with active coolers by SEPA EUROPE however, the new Kühligels are not only small and light but also extremely inexpensive. Thanks to intensive development work, SEPA EUROPE was able to construct a heat sink that enables fan mounting without extensive reworking using conventional screws. The choice of the suitable fan (size, sleeve or ball bearings, 5, 12, or 24 VDC, tacho, connector) enables the best possible combination that is required for the application in question. The fans used have a MTBF of up to 350000h (40°C) and thus meet the highest requirements. Thanks to its light weight, the Kühligel® can usually be mounted using double-sided adhesive heat conduction pads (TCTxx) or thermally conductive two-component adhesive (Hernon 746) which are both available from the SEPA EUROPE product range.

Thanks to the intelligent combination of DC fans with a fully integrated AC/DC converter, AC fans can now be operated at speeds that are independent of the power frequency. Up to 4500 rpm can be realized and the flow rate significantly increased if required. The EC generation in the dimensions 80mm to 280mm and with several different speeds replaces the previous AC fans in situtations where there is no DC voltage available and requires less power in the process. The previous AC fans can be replaced without restriction as the EC fans have identical dimensions and thickness. The versions that are smaller than 180mm have a wide-range input and can be connected without problem, worldwide to all AC voltage networks without need for further adaptation. This is underlined by the UL approval of the entire fan series.

SEPA EUROPE offers a 40 mm frameless fan especially for embedded systems. It is 10 mm high and provides a compact solution for chip cooling when used in combination with the appropriate heat sink. In addition to the 50 mm frameless fan which is already on the market, the new round 40 mm fan is also a much sought-after model for embedded systems. This is because many standard cooling solutions in this business sector are based on the 40 x 10 mm fan. Strictly speaking, the 40 mm fan has a rotor diameter of 37 mm. The version offered by SEPA EUROPE is equipped with two ball bearings and can boast a remarkable service life of 70.000 h at a temperature of 40°C. In addition to an impulse output for speed monitoring, it also has a PWM input for speed setting in the range of approx. 35 – 100% of the nominal speed. In conjunction with the power block pin-fin heat sink, this virtually silent fan with 22 dB(A) is also available ready for connection in the „Kühligel“ version.

Passive cooling solutions are usually too big. Small active heat sinks are the ideal solution. Stable light colours, a high life expectancy and low energy requirements are the unbeatable advantages of LED technology. However, whereas the energetic superiority comes virtually automatically, considerable investment must be made in thermal management to fulfil the demands on the colour values and service life. Only well cooled diodes can keep what they have promised in the long run. For optimum thermal management, SEPA EUROPE offers not only passive cooling solutions but also active heat sinks. Active cooling concepts usually provide the ideal solution when space is a problem. They are smaller and lighter, can attain the desired service life, are attractively priced and find space virtually everywhere. SEPA EUROPE already supplies its customers with fans that are adapted to the application in question and in some cases with special waterproof fans.
