Nicotra Gebhardt RZM direct driven centrifugal fan with coupling

Nicotra | Gebhardt Direct driven centrifugal fans

RZM

Economic, quiet and compact: the RZM coupled direct driven centrifugal fans set new standards for economy and quiet operation.

Overview

About RZM

Nicotra Gebhardt developed the series by combining two high technologies: the aerodynamics of the rotavent impeller and energy efficient IEC motors.

Features

Your benefits

Powerful fan range direct driven with coupling

Maintenance and wear free drive (no V-belts)

Short payback time due to high energy saving, especially with long operating periods

Higher comfort levels through particularly low noise fans and motors

Problem free speed control with frequency inverter

Optimal aerodynamics

Low turbulance velocity for both inlet and discharge due to the large free cross section and minimal flow restraint of the impeller, an example of aerodynamics and performance of the rotavent.

Acoustics

Reduction of high frequency noise levels is just one of the advantages of the rotavent, together with optimised motors and frequency inverters. Minimal sound levels due to low blade passing frequencies from the optimised impeller geometry of the rotavent. The impeller has obliquely inclined blades with trailing edges, and the throat plate is inclined opposingly.
