GRAF S.p.A. compressor units series GRF115-4B come out from the growing need, arose from our customers, for more capacity with low inlet pressure.
These compressors are projected and realized in order to get high performances and to maintain low energy consumption, reducing the overall dimensions and then the installation of additional compressors, where high flow is requested (i.e. bus stations). They are designed in order to reduce the ordinary and extraordinary maintenance costs and avoid unexpected machine stops.
Compressor units are realized with latest-generation components and European high technology for ensuring its safe use in accordance with the valid safety rules.
All the compressor units are available with a range of electric power from 90 up to 450 kWh with different inlet pressure, capacity and stages.
