AC Axial Fans | AC Radial Fans
Decades of development work and experience gained from millions of units produced in series make PAPST AC fans products that are constantly being copied. With its multitude of patented innovations PAPST today is still setting increasingly new standards. Where the functional reliability of high-tech appliances demands efficient cooling, the very latest AC fan series heads the priority list as far as quality and reliability are concerned.

DC Papst Fans
DC Axial Fans | DC Mixed Flow Fans | DC Radial Blower
Users of PAPST fans can choose from the widest range of DC fans. PAPST offers a comprehensive range from 25 mm edge length to a diameter of 172 mm. Every single type of fan can be integrated in the individual device concept. The highly economical, brushless motor technology of these fans offers a unique variety of intelligent innovations - advantages of the DC fan that can be realized today at prices that were unthinkable just a few years ago.

Technical Features: Maximum power consumption of forward curved centrifugal fans is reached at free blowing. As the back pressure increases, the power consumption decreases. The integrated external rotor motor is mounted in the air stream for optimal cooling. All motors have a special torque vs. speed characteristic and are speed controllable.

Scroll Housing: Forward curved centrifugal fans with scroll housing are available in three different versions: a) aluminium die-cast alloy, with the two housing parts being screwed together b) Case and side parts consist of galvanised sheet steel and are joined together by shorts and tabs c) heat-resistent plastic

Scroll dimension / Scroll Housing Forward curved centrifugal fans require scrolls as guide. The scroll leads the air stream from the impeller to the pressure stud. The dimensions of the centrifugal blowers can been taken from the corresponding datasheet.

Single Inlet Centrifugal Blowers are available in either single or 3 phase. Impeller diameters range from 76mm to 250mm. Please choose required data sheet:

230v Single Phase or 400v Three phase

The integrated external rotor motor is mounted by means of a bracket on one side of the scroll housing. An external rotor motor with standing shaft (EW) can be used for size 133 and bigger. The motor is mounted on both sides of the scroll by means of anti-vibration mounted brackets. These fans have extremely low vibration values.

Double Inlet Centrifugal Blowers are available in impeller sizes 97mm to 250mm. Voltage of 230v Single phase and 400v Three Phase are available.

The main feature of backward curved centrifugal impellers are the extremely long, backward curved blades, when looking at the direction of rotation. These impellers are less sensitive to dirt and dust. Furthermore, they offer very good hydraulic efficiency. Their primary advantage is in sucking operation. A scroll housing is often not required. Depending on the application, it might be sufficient to mount the centrifugal fan in a rectangular or round scroll to convert part of the dynamic pressure. The dimensions and performance of these impellers are particularly suitable for use in range hoods, computers and computer peripherals, duct fans, roof ventilators, etc. In range hoods, for example, the rectangular over-pressure area makes it possible for the user to select the outlet direction, either "exhaust air" or "recirculated air".

Hot air blowers move hot air in cookers, convection ovens, climate chambers, etc. The hot air blower and its motor are designed in such a way that the high ambient temperatures do not affect its operation and long mechanical life is assured.

The main features of external rotor motors as drive motors are constant speed, very low noise levels and compact construction. The relatively high inertial mass of the external rotor motor guarantees constant speeds at different loads. The motors listed in this catalogue only give an overview of our complete motor range. If required, the motor design can be made to customer specifications. Motors for thermostats and beverage coolers, usually closed, are equipped with a stainless steel shaft. All rotors are varnished black. On request external rotor motors are available as brushless DC motors. These motors have a high efficiency and are offered in different electronic options. We also offer external rotor motors as brushless EC motors. These motors have a high efficiency and with the electronics used they can be offered in different versions. Even connection to a 230 VAC power supply is available. See also ebm EC standard.

Hot gas fans are ideal if hot gas needs to be moved. Using the same principle of a centrifugal blower, gas is drawn in from the side and pushed out. This unit is ideal if pressure is required

The name "JB Motor" comes from the German word "jochbewickelt" and means that the coils of the stator winding are wound in radial direction over the stator stack. This special winding is similar to the winding of a toroidal core transformer or a variable resistor. The stator is completely moulded with Duroplast. At the same time the Duroplast moulding serves as the housing of the motor. The motor is an asynchronous short-circuit rotor motor designed as single-phase AC motor with operating capacitor. Three-phase motors are available on request. A particular advantage of the JB motor is the small coil form resulting in shorter motor stacks and more compact motor design. The moulding of the stator guarantees smooth running, free from solid-borne noise and vibration, and higher life expectancy of the stator winding as dust and other damaging particles, humidity in particular, cannot penetrate. The construction of the JB motor ensures high reliability.

Crossflow fans have been in existence for more than 80 years, but it is only the result of intensive development work carried out over the past few years that has made it possible to construct them with characteristics comparable with those of other fans. From the basic conception, we have, through systematic research, developed a new type of crossflow fan. The introduction of a perforated “V” shaped guide vane into the air stream gives the following technical advantages: • high stability • excellent performance characteristics in relation to overall dimensions • very low noise level • a wide range of applications
