A clean production environment is crucial for process reliability, machine availability, and employee protection. Especially with modern CNC lathes such as those from the Tornos Group, high coolant pressures generate fine oil and emulsion mists that must be reliably captured and separated.
With the two-stage electrostatic air filter system E 120-2, LTA offers a powerful solution for precisely these requirements.
Single-stage or two-stage electrostatic filtration – the difference
In electrostatic air filter systems, “single-stage” does not mean that there is only a single filter component. Even single-stage systems have:
- a pre-filter
- an ionizer
- a collector
What does two-stage filtration mean?
In the two-stage version, such as with the E 120-2, the existing system is extended by a further electrostatic stage:
additional ionizer
additional collector
This second ionization and separation stage ensures that even the finest aerosols are specifically charged and separated again. This significantly increases the separation efficiency, especially for very fine oil and emulsion mists.
When is a two-stage solution appropriate?
The decision between single-stage and two-stage filtration depends largely on the coolant pressure:
Up to 40 bar
→ Single-stage systems (e.g. E 120-1) are generally sufficientOver 40 bar
→ Two-stage systems (e.g. E 120-2) are recommended
At high pressures, particularly fine aerosols are produced, which can be separated much more efficiently with an additional electrostatic stage.
