Drum filtration unit Spring Compact series

for coolantcompactstainless steel

Spring Compact is a self-cleaning drum filtration system capable of treating from 100 to 5000 l/min of neat oil or emulsion. Drum filtration efficiency can be customised according to customer requirements. Spring Compact has the special feature that it only processes the amount of coolant required by the machine; the clean liquid collection tank is welded as a single block with the filter. Spring Compact works in real time, eliminating sludge deposits in the tank and thus guaranteeing zero deposits at the bottom of the machine. Given the characteristics of the filter, the system is designed and sized to the customer’s specific requirements. This type of self-cleaning filter is especially suitable in the mechanical engineering and automotive industries, where there are machining operations involving chip removal with tools, abrasion removal, deformation and washing. The Spring system uses a metal filter cloth which is cleaned by the Autoclean system. In this way, no consumable materials are used, significantly reducing maintenance and waste disposal costs. This is an automatic cleaning system for the wire cloth used for filtering liquids. Inside the filter is a sensor that rotates the drum when the maximum filter cloth clogging level is reached. During the rotation, a countercurrent jet system washes the wire mesh, removing the residue while the dredging system scrapes the sludge from the bottom of the tank, transporting it to the outside.
