About brand
Many of the compact fans inside control cabinets, drives and cooling units carry a Papst or ebm-papst label. The company, based in Mulfingen, Germany, and dating from 1963, makes fans, blowers and the motors that drive them. Seven Star LLC lists Papst industrial cooling fans and supplies ebm-papst fans as replacement parts to plants and panel builders in Oman and the GCC.
ebm-papst fan types
The catalog divides into axial fans, centrifugal fans and blowers, and compact fans for electronics cooling, in AC, DC and EC motor versions. Older compact fans are labeled Papst only, which is why maintenance staff still ask for a "Papst fan" by that name. The label gives a type code, and that code is what defines size, voltage, speed and air performance.
Ordering ebm-papst fans: what we need
Copy the complete type code from the fan label, for example a four-digit type with its letter suffix, or the longer code used on larger fans. Add the voltage and frequency, frame size and depth in millimeters, the connection (leads, terminals or plug) and the airflow direction. If the label is unreadable, send the dimensions, voltage and a photo.
