The Cyclofilter can operate under both positive and negative pressure. The particle-laden air enters the dust filter through a tangent inlet; the particles are centrifuged down to the cone section where they are continuously collected by a pneumatic or mechanical system. The finer dust is captured upward in the filtering section using filter bags. The clean air is returned to the plant or to the atmosphere.

The particle-laden filter bags are cleaned continuously with an air-pulse jet system controlled by a sequential timer.
The conception of the Cyclofilter reduces the upkeep of filter bags, since the cyclonic pre-separator reduces to a minimum the dust load on the filter bags during the operation of the Cyclofilter.

Rodrigue Métal has developed a whole range of remarkably efficient Cyclofilters based on research and development as well as on our numerous accomplishments.
