General description

Introduction

QOF 20, QOF 22 and QOF 30 are stationary, oil free compressors.
Dependent on the model, the compressors have 3 or 4 electric motor driven compressor

modules, enclosed in a sound insulating canopy. The front door panel houses the controller

with graphical display and the emergency stop button. An electric cabinet with the electric

components is located behind the front panel.

The compressors can be delivered with or without integrated refrigerant air dryer.
QOF is the type designation of the compressor variant without integrated dryer. On QOF,

the compressed air of each compressor module flows via an individual check valve to a

common air cooler and leaves the compressor via the air outlet valve.

QOF with dryer compressors are QOF compressors provided with a refrigerant air dryer,

integrated in the bodywork.
The dryer removes moisture from the compressed air by cooling the air to near freezing

point and automatically draining the condensate.
