Master is a range of high efficiency gravity filters, using non-woven fabric as filter media.
Master series is available in 4 models, able to manage flowrates from 200 to 1000 l/min of neat oil and from 400 to 2000 l/min of water based emulsion, contaminated by magnetic or non-magnetic particles. Medio Master is available in 3 models, able to manage flowrates from 200 to 400 l/min of neat oil and from 400 to 800 l/min of water based emulsion, contaminated by magnetic or non-magnetic particles. Mini Master is available in 3 models, able to manage flowrates from 60 to 200 l/min of neat oil and from 100 to 400 l/min of water based emulsion, contaminated by magnetic or non-magnetic particles.
The filtering fabric (A), stretched inside the filter, is perfectly clean. The dirty liquid enters in the system and has to pass through it to go to the lower tank, thus depositing pollutant particles on its surface. The clean liquid goes through the lower part where the discharge opening (B) is located and falls into the tank underneath. During this phase the system is idle and the fabric is not advancing; pollutant which is deposited on the filter fabric forms the actual filtering layer, which in many applications can reach a thickness of 10 mm.
The dirty filter fabric permeably is reduced, because the dirty liquid continues to deposit the pollutant onto its surface, and the coolant level starts increasing. The filtration degree improves due to the thickness of the mud deposited on the filter fabric. During this phase the system idle.
The liquid has reached its maximum level, at this stage the best possible filtration degree is actually reached. The longer the filter operates in this conditions, the better the average filtration will be. The system is idle also in this phase.
When the fabric is totally obstructed and the liquid cannot pass through it anymore, the regeneration cycle begins. Motor reducer allow the system to rotate and moves the dirty filter fabric (C), while the clean one is introduced and permeability restored, allowing for the level to descend and return to intermediate condition 2.
Superficial oil skimmer, it allows to lengthen coolant quality and eliminate odors generated by anaerobic bacteria.2. DMD
Pre-filtration system with rotating magnetic discs for the separation of magnetic polluting particles from coolant.3. Electrical panel
For powering the system, control and command all signals.
For clean liquid to be sent back to machine tool.5. Transfer tank
To collect dirty liquid for feeding the filter.6. Pumps
For pressure from 0,1 to 100 bar for returning clean liquid.
