The pre-separators operate either according to the principle of centrifugal force or by using the thermal energy of particles. Keller offers three choices of models to meet any requirement.
Material separator MVA of high-quality sheet steel construction, consists of:
By centrifugal force, the dirty air enters the cylindrical chamber of the spark pre-separator through an external inlet. The dust particles are propelled against the outer wall and spiraled downward to the funnel-shaped discharge. The clean air exits the spark pre-separator through an upper exhaust air outlet.
This compact impact separator is designed with high-quality sheet steel for direct installation on filter units VARIO 1-6, for the purpose of preventing sparks. The dirty air flows into the pre-seperator, is deflected by the baffle plate, and continues into the hopper area. Hot embers are removed and large particles are seperated from the airflow. Disposal occus via a bucket mounted underneath.
This high performance cyclone separator is designed in high quality sheet steel and consists of:
The mechanical seperators operate according to the centrifugal forces principle. The dirty air enters the cylindrical chamber of the spark pre-separator through an external inlet. The dust particles are propelled against the outer wall and separated downwards through the funnel-shaped discharge. The clean air exits the pre-separator through an upper, central exhaust air outlet.
