Displacement and dynamic compressors — Performance test code for electric driven low-pressure air compressor packages

This document specifies the performance test method of electrically driven low-pressure air compressor packages, where the compression is performed by positive displacement or dynamic compression; utilising atmospheric air as the compression gas. Low-pressure air compressor packages are often referred to as “blowers”.

NOTE??????????? Throughout this document, the term ‘low-pressure compressor’ is used to describe a low-pressure air compressor (“blower”) package

Low-pressure compressors with and without means of controlling flow (control may be electrical (e.g. with a variable frequency drive) or mechanical or both) are covered.

This document applies to low-pressure compressors meeting all the following limits:

—???? Atmospheric inlet air pressure between 0,5?bar and 1,1?bar.

—???? Discharge vs inlet pressure differential between 0,1?bar and 2,5?bar.

—???? Discharge vs inlet pressure ratio between 1,1 and 3,5.

This document is not applicable to:

—???? positive displacement low-pressure compressors with a liquid in the compression element (such as liquid ring pumps and liquid injected low-pressure compressor of screw type)

—???? multi-stage low-pressure compressors other than multistage centrifugal compressors comprised of multiple, identical or very similar uncooled sections along a single shaft (repeating stages).

—???? single shaft, multistage centrifugal compressors are treated from the point of measurement and calculation as a single stage
