Cler installs at the kitchen hood, where cooking exhaust is at its most concentrated. As air passes through the unit, it is spun at high speed. Centrifugal force separates grease particles from the airstream based on weight. The clean air continues into the ductwork while the grease drains away automatically during operation.

Grease separated from the airstream drains continuously into a collection container attached to the Cler unit. The container is emptied as part of routine upkeep. No grease enters the ductwork, which is what keeps the downstream system clean over time.

Maintenance is minimal. Cler monitors its own performance around the clock, tracking air quality, pressure, power, and temperature in real time. If performance drops or something requires attention, an alert is sent automatically. There are no filters to replace and no manual cleaning of the separation surface.

Because Cler captures grease before it enters the ductwork, grease deposition in the ducts is significantly reduced. At McDonald's Gotland, duct inspection after twelve months with Cler recorded the lowest grease levels the attending chimney sweep had seen in an active kitchen. Most kitchens with Cler require less frequent professional duct cleaning than under a conventional filter system.

Both units use the same filter-free centrifugal separation technology and deliver the same performance. The Compact is a smaller version designed to fit tighter spaces and installations where the standard unit would not. Your site assessment will determine which is the right fit.
