Gravity filtration system Micro Master series

Micro Master is a series of high-efficiency, gravity-operated, high flow coolant lubricant purifiers using non-woven fabric as the filter medium. The Micro Master series is available in two models with flow rates from 60 to 100 l/min of neat oil and from 100 to 300 l/min of water-based emulsion, polluted by metal and non-metal particles. Micro Master is reliable and guarantees stable, consistent operation over time. This type of filter is particularly suitable for heavy-duty machining, machining with light alloys (aluminium, brass, etc.), applications with neat oils and 24- hour machining. All Master series models are equipped with a corrugated metal chain which, thanks to the side sealing discs, guarantees a perfect seal of the dirty liquid in the filter section. The filters in this series use a disposable filter medium, which allows the degree of filtration to be varied by changing only the type of filter, always achieving excellent results. Compared to flatbed filters with the same flow rate, the Master range has a considerably smaller footprint and achieves a better degrees of filtration. Operation In the initial phase the fabric, stretched inside the filter, is completely clean. The dirty liquid entering must pass through it into the lower tank, where it deposits the pollutants on its surface. The clean liquid then passes into the lower part where it finds the drain opening and falls into the collection tank. During this phase, the system is stationary and the belt does not advance. The pollutant material that settles there forms the actual filter layer, which in many applications can be up to 10 mm thick.
