Suitable for dry and clean compression of air and neutral gases.

A single series for all volume flows.

They are among the world’s best-selling compressors: the direct-drive units that bear the name Delta Screw. Why? Because there is probably no other compressor that so uncompromisingly fulfils even the most demanding client requirements. Because you can cover a very broad range of volume flows with a single machine. Because these compressors are most efficient. Because they are legendary for their operational availability and longevity. And finally, because these amazing all-rounders have a huge advantage: they are “Made by AERZEN”.

11 Models. All contingencies.

They operate reliably in all the world’s temperature zones, indoors and out, in mobile or stationary deployment. What makes the Delta Screw so flexible? 11 direct-drive machines. 2 compressor groups with the specialised AERZEN rotor profile. A choice of discharge port sizes in the cylinder for ideal internal compression. And an almost unlimited spectrum of possible adaptations and accessories. Designed for the compression of air, nitrogen, and other neutral gases, the Delta Screw compressors are perfect for almost any possible application. The spectrum of the extended Delta Screw series additionally includes 7 belt-driven compressor models for volume flows (actual delivery depends on intake parameters) from 120m³/h to 2,650m³/h.

Delta screw E-compressors. The savings will pay for the machine.

6% lower energy usage compared to conventional compressors – the AERZEN E-class (VML 60 G5-E, VML 95 G5-E, VM 45 G5-E, VM 75 G5-E, VM 100 G5-E) is making a significant contribution to the realisation of legal and company energy savings programs. And with almost 90% of total costs taken up by energy, this means releasing serious potential that can be devoted to environmental protection, improved company liquidity, and reduced life-cycle costs.

5 x E. Discover the Delta Screw success principle.

Efficiency. Essentials. Ecology. Elasticity. Evolution:

AERZEN’s guiding principle for success is compressed into the 5 big “E”s. It’s expressed in a number of intelligent details – and in a well thought out generation of compressors: the Delta Screw E-Compressor.

Efficiency

Lower TCO

  • Up to 6% energy savings
  • Low maintenance costs
  • Flexible on-site service

Cool external supply air (E-Compressor)

  • Compressor air intake from outside the acoustic hood
  • Up to 10°C lower intake temperature
  • Separate intakes for process and cooling air

Essentials

Just plug & play
