PRESENTATION
The LAFFI FILTRATION Centrifugal Separator Filters remove by centrifugal action, the solids (grains, fine metal chips, fines and other high density solids), with high efficiency keeping low concentration of solids in tanks and various processes, reducing the accumulation of solids in cooling towers, heat exchangers, chiller and other cooling system equipment.
Performance and quality approved in several market segments.
These units require little or no maintenance, as there are no moving parts that can fail or wear out, or filter elements to clean or replace. The unit requires only a simple automated purge eliminating downtime for cleaning
It meets flow rates of 0.7 ~ 2900 m3 / h with solids retention efficiency of up to 98% for solids above 50µ.
PRINCIPLE OF OPERATION
1. Liquids / Solids enter the unit tangentially to produce a circular flow.
2. Liquids / solids pass through tangential grooves where they are accelerated into the separation chamber.
3. The centrifugal force hurls the heavier particles to the perimeter of the separation chamber, depositing them on the bottom of the unit.
4. The liquid free of solids is kept in the center of the separator by going to the outlet at the top.
5. Clean liquid outlet.
6. Concentrated solids are periodically purged or continuously drained from the separator as needed.
