Self-ventilated or forced-ventilated motors of the IC 411 or IC 416 standard are part of everyday life and everyone knows them. The standard motor, or at least the drive of many industrial machines that looks like a standard motor, has a fan guard, a fan blade underneath it and associated cooling fins on the circumference of the stator housing.

From the outside you usually cannot see what is inside.
Often also with three-phase motors, which are operated by means of frequency converters from 50Hz or 60Hz to more than 300Hz. Fans cover, ribbed housing... From the outside, everything points to a "normal IEC motor"...

High flowrate and enormous pressure increase?
The Dietz SB High Performance Blower for frequency converter operation can do both! On the one hand, high flow rates and good efficiency over a wide range of characteristic curves, on the other hand high pressure increase or decrease...

High-pressure fans of the HR series solve the most diverse ventilation tasks in many areas. They are designed for high pressure differences (positive or negative pressure) and thanks to operation via frequency converters, these centrifugal fans can be flexibly optimised for a wide range of applications ...
