Continuous ultra-clean air
Filters work, until they don't
Traditional filters trap particles in material.
The material clogs. Pressure rises, energy increases, performance drops and the denser the filter, the faster it happens.
Cler doesn't trap particles. It separates them.
Air spins at high speed, centrifugal force pulls particles out by weight, and they drain away continuously.

Filters work, until they don't
Traditional filters trap particles in material. As the material fills up, pressure rises, energy increases and performance drops. The denser the filter, the faster it happens.
Cler doesn't trap particles. It separates them. Air spins at high speed, centrifugal force pulls particles out by weight, and they drain away continuously.
How Cler is built


Air spins at high speed. Centri-fugal force separates particles by weight. Forces up to 5,000 g. Catches particles down to PM0.5.


Stacked cone-shaped plates. Air passes through narrow gaps. 25-000 m² separation surface. Low pressure drop maintained under heavy load.

Particles rinse away continuously. 0.5 dl/month for a 1,000 m² building. No manual cleaning. The separation surface stays clear.
