Profiles and styles for overpressure applications
The rotary lobe compressor unit Delta Hybrid has a 3+3 twisted rotor profile which is used for low pressures up to 800 mbar (12 psi) whereas a 3+4 rotor profile is used for pressures up to 1500 mbar (22 psi): a compressor with optimum efficiency can be selected for the needed pressure range.
