How Cler works

Continuous ultra-clean air

Filters work, until they don't

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

High-speed separation

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

The lamella creates separation

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

Selfcleaning during operation

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

No maintenance. No waste.

Just clean indoor air.

How Cler works
in practice

01

Commercial kitchens

Grease captured before it enters ducts. Clean ventilation ducts. Minimal maintenance and a system that runs continuously.

02

Commercial buildings

Consistent ultra-clean indoor air quality. No filter schedules. No performance drop between maintenance.

03

industrial facilities

Particle removal without downtime. Stable cooling performance. No risk of filter-related outages.

04

Data centers

Handles extreme particle loads. No clogging under dust bursts. Continuous operation in harsh environments.
