Versus scrubbers



Caeli filters

1. Complexity

Complex system of aggregates and apparatus designed to capture mechanical air particles (dust).

One or several cascade-connected grids through which the passing air is moistened by a system of nozzles. The nozzles spray water into a grid through which the air is passing. The grid is usually having a form of a labyrinth.

  • Compact

  • Single filter body

  • Easy to install

2. Principle

Mechanical (Grid)

Water cyclones

3. Pollutants


Mechanical particles only


+ All Mechanical (rough & finest) + All Biological (bacteria & viruses) + Most of Chemicals + Most of Aroma see how

4. Efficiency

Avg. efficiency: 86%

Avg. efficiency: 99.3%

5. Stand-alone option

Not possible


6. Retro-fit option

Not possible

Requires pre-defined design and infrastructure, also large available space. Complexity in re-arranging the space to fit the whole new scrubber.


With minor (quick, easy and low cost) adjustments

7. Maintenance

Time and money consuming, complex cleaning, high labor costs for staff training, daily operational monitoring, and for maintenance of all aggregates (as scrubber are complex systems and require constant maintenance).

Easy and low cost.

Self-cleaning: Fully-automated or
semi-automated (depends on the factory type and pollutant specifics).

8. Consumables

Numerous Water filters, nozzles (avg 100+ pieces per installation) which requires frequent change of elements.

No removable and/or interchangeable parts.

9. Outlet humidity

High (90-96%)

90-96% humidity of the outlet air (Additional investment in dehumidifiers is needed)

Normal (50-70%)

Low humidity at the outlet since the third cyclone of our filter works like an air drip and a dehumidifier.
