1.5.2 Purpose

The screw compressor air ends are oil-injected 

screw compressor air ends that form a perfectly 

matched compressor unit when completed with 

components from the ROTORCOMP product 

range. 

The sole intended use of the system is the com-

pression of atmospheric air. The screw compres-

sor air ends may only be used to compress gases 

or other media following written approval by 

ROTORCOMP.

The installation of the screw compressor air ends 

or the assembly of these with components to form 

a compressor unit may only be carried out by spe-

cialized companies with the corresponding know-

how.

The safety precautions, technical data, limits, 

installation guidelines and regulations for commis-

sioning and operation specified in this operating 

manual must be observed and complied with.

1.5.3 Delivery scope

ROTORCOMP supplies screw compressor air 

ends in accordance with the order confirmation.

1.5.4 Optional components

ROTORCOMP offers matching components for all 

screw compressor air ends for system construc-

tion. As a result, there are also matching compo-

nents for an extremely broad range of applications 

and operating modes. The "Screw Compressor 

Technology" catalog from ROTORCOMP is avail-

able to help you choose the right screw compres-

sor air ends and components. 

Optionally available components are marked with 

(optional).
