COOLANT FILTRATION SYSTEM, INDUSTRIAL COOLANT FILTRATION, EMULSION FILTRATION, HIGH EFFICIENCY FILTERS
Spring is a self-cleaning drum filtration system, with permanent metallic net, suitable for removal of magnetic or non-magnetic particles from neat oil or emulsion.
Restorable Stainless steel metallic net
Dredge system for mud discharge
It is available in 9 sizes with flowrates ranging from 25 to 1000 l/min of neat oil and from 50 to 2000 l/min of emulsion. The drum’s filtration efficiency can be customized according to customer requirements.
The metallic filter net covering the drum is clean (A). the dirty coolant passes through it depositing the pollutant particles and goes through the discharge opening (B). from here the clean coolant falls into the collection tank positioned below, from where pumps will transfer it back to the machine tool. During this phase the drum does not rotate and the dredging system is stationary. The polluting particles deposited on the filter net forms the actual filtering layer which can also reach a thickness of 10-15 mm.
As the filter net gradually gets dirty, the liquid level increases. The dirty coolant continues to deposit pollutant particles onto the drum surface, while the drum and dredging system (C) are still. The filtration level improves due to the thickness of the mud deposited on the filter net.
Coolant cannot pass though the filter net any longer – filter net clogging cycle is complete this phase is when the best filtration level is reached. The longer the filter operates under these conditions the better the average filtration will be. When the coolant reaches the maximum internal level allowed, a self-cleaning cycle is started automatically. At the end of this phase the coolant level descends and the filtration cycle begins again.
