Installation precautions for fans
The mainstream installation methods of fans are horizontal and vertical shaft installation, but the installation requirements of each fan are different, and not every installation method is supported.
First, fans basically support horizontal shaft installation
Let's look at centrifugal fans: (When the centrifugal fan shaft is installed horizontally, pay attention to the direction of the lead wire)
The lead wire is facing downward because when used outdoors, the direction downward can prevent water from directly entering the terminal gap
Second, sometimes you will face the form of vertical shaft installation. At this time, you must pay attention. The fan generally requires the stator side to face up and the rotor side to face down. Some fans have drip holes on the rotor. If the rotor is installed upward, if there is condensed water, the water will enter the drip hole and cannot be discharged, so the rotor must be installed downward so that the condensed water can be discharged
For backward centrifugal fans with brackets and mounting plates, ensure that the brackets are on the left and right sides of the fan during installation. If the brackets are on the upper and lower sides of the fan like the second picture, the brackets may be deformed due to long-term operation and rub against the fan.
Of course, this is not absolute. Some fans can still support any form of installation. -
Characteristics and classification of centrifugal fans
It is called a centrifugal fan because it relies on the centrifugal force of the impeller to inhale the gas axially but blow it out radially. Its structural characteristics enable it to withstand greater wind pressure than axial flow fans.
EBM-PAPST centrifugal fans are divided into forward centrifugal fans and backward centrifugal fans according to the different impeller structures. Different impellers create different characteristics and applications of the two fans.
The forward centrifugal fan has small blades, large numbers, and high density, so the overall structure is more compact and quieter, suitable for small spaces and high wind pressure environments, but it outputs a small amount of air and generally needs to be used with a volute.
The backward centrifugal fan adopts a free wheel design and does not require a volute. Compared with the forward centrifugal fan, it can output a larger amount of air, but it can withstand less wind pressure.
For centrifugal fans with external rotor motors, the motor is integrated into the impeller, which not only ensures excellent cooling of the motor, but also achieves a very compact design.
The entire product range offers AC fans and EC fans with EC technology. In addition to energy saving, the integrated control circuit of EC fans can also realize control, monitoring and maintenance functions, which are particularly suitable for purification, industrial air conditioning, fresh air systems, electronic cooling and other related applications.
ebm-papst centrifugal fans are unparalleled high-pressure experts in centrifugal design with 90° air deflection and carefully optimized impellers.
