Aerosol booster with piston pumps and PRO-CYCLON® technology with up to 10bar to produce fine oil-air mixtures

Main application range:

Internal MQL for single channel rotary union, middle and upper rotational speeds.

Operating principle:

In the case of internal lubrication only the finest drops are able to get through as the centrifugal forces inside the spindle eject the bigger oil droplets. The Centermat® C30 utilizes this effect through its use of PRO CYCLON® technology. Coarse droplets are separated in the Centermat® C30 early on and transported back to the supply reservoir, thereby minimizing consumption. The smallest droplets in the µ-range that remain form a fine, stable aerosol mixture which is transported to the drill holes in the machine tool all the way through the feed tube, rotary union and spindle. The Centermat® C30 can be operated with up to 10bar operating pressure and 8bar spray pressure. This means that the Centermat® C30 achieves 83% more aerosol throughput than its predecessor (4 bar spray pressure).

Product versions:
The Centermat® C30 can be ordered with one, two or three spray nozzles. The C30 version with only one spray nozzle is sufficient for applications where only a single or a small number of tools with similar total cross sections (TotalQWZ) are to be lubricated. Two or three spray nozzles are useful when lubricating a wide range of tools with different total cross sections (TotalQWZ).

In addition, you can choose whether all nozzles are installed as large nozzle “G” or whether you want a mini nozzle “M”. The mini-nozzle is required for particularly small total cross-sections (TotalQWZ) of 0.07-0.28mm².

All C30 versions always have an additional, separately controllable supplementary air. This can optionally be used for blowing out the spindle, removing chips or increasing the air volume for particularly large tools.
