DUALLUBE is a two-stage oil-lubricated screw compressor family for industrial air at 8/10/13 bar.
Description
DUALLUBE two-stage oil-lubricated screw compressor
DUALLUBE is an oil-lubricated two-stage screw air compressor that splits the compression process across two separate sets of helical rotors. Dividing the total compression ratio into two steps lowers internal leakage, reduces bearing stress, and can deliver up to 15% more airflow using the same power as a single-stage unit. It is for plants that need a two-stage machine rather than a single-stage SILVERLUBE unit.

What does the DUALLUBE two-stage range cover?
DUALLUBE is the two-stage oil-lubricated family. The brochure shows 8, 10 and 13 bar. Confirm the exact kW and FAD on the current model row; do not reuse single-stage SILVERLUBE figures.
Architecture
Two-stage screw
- Pressure options
- 8 / 10 / 13 bar
- Why two-stage
- Higher pressure ratio and up to 15% more airflow
- Not the same as
- SILVERLUBE single-stage
How to choose
By duty point
- Start with
- Required FAD and pressure
- Then check
- Whether two-stage is needed
- Before a quote
- Confirm the model row
Use the brochure for the full model table, then confirm the selected row before quotation.
How do you select a two-stage oil-lubricated screw compressor?
Use a two-stage compressor when a single-stage cannot meet the required pressure ratio and capacity and better energy efficiency is needed. Start with FAD and working pressure, then confirm the DUALLUBE model.
Duty point
Set airflow and pressure
Record required FAD and 8, 10 or 13 bar.
Architecture
Confirm two-stage is needed
If a single-stage SILVERLUBE model already fits, do not force a two-stage quote.
Quote check
Select the exact model
Confirm the DUALLUBE model, FAD and package contents on the current datasheet.
What should you confirm before asking for a quote?
These checks keep a series overview from being treated as a project specification. Wider system design stays a separate discussion when it is needed.

Frequently asked questions
What pressure options does DUALLUBE offer?
The family table shows 8, 10 and 13 bar. Confirm the model row.
Is DUALLUBE the same as SILVERLUBE?
No. DUALLUBE is two-stage. SILVERLUBE is the single-stage family.
Is this a system design page?
No. It is a product page for a two-stage oil-lubricated screw compressor.
