Magnetic Filtration The Micromag Way

25 August 2005

Eclipse Magnetics Ltd latest product, the Micromag filtration system promises huge advantages in fluid filtration claims Steve McAllorum, Eclipse’s Technical Sales Manager.

Re-circulating magnetic particles in any machine tool, especially precision grinding applications, have many negative effects. Pump, slide way & hydraulic seals wear prematurely, oil & coolant life is massively reduced due to bacterial growth, which can be associated with foreign bodies such as metallic particles and in some cases stops the fluid from performing their critical tasks of cooling & lubricating at the cutting face.

Surface finish and component accuracy can also be affected along with the need to redress cutting wheels on an excessive basis. All resulting in higher operating costs and reduced profit!

Micromag can be utilised in any fluid application where ferrous or paramagnetic contamination is present. The unit is especially effective with machine tool oils & coolants and comprises of a hard wearing clear filter body, anodised Aluminium lid and a high intensity magnetic core.

The magnetic core incorporates Neodymium Iron Boron magnetic material or ‘Rare Earth’ as it is more commonly known, that generate extremely high intensity magnetic fields. It is these high magnetic forces that can attract even a sub micron sized particle ensuring that even the dirtiest of fluids are thoroughly treated prior to it being used.

Micromag is available in three housing sizes 5” & 10” with 1” inlet/outlet ports and a 20” unit with 1½” ports. All units are supplied with port adaptors to suit most pipe connection sizes.

The 10” bodied Micromag’s core can hold 2kgs of contamination before the unit requires cleaning. This allows for extended operating durations and minimises downtime resulting in uninterrupted machining. Where contamination generation is high, the 20” Micromag can be utilised, which is capable of holding 4.5kgs. Where loading is extreme and machine operation is critical Micromag’s can be installed on a duplex set up.

The clear filter housing gives the operator a visual indication when the unit requires cleaning. Cleaning is very simple and is conducted using the supplied cleaning tool. The units can be fully cleaned and back on line within one minute, minimising downtime.

Micromag has many benefits over more conventional forms of filtration. There is no fluid loss and no pressure drop even when fully loaded with contamination. The Sub micron filtration efficiency means that if the particle is magnetic the Micromag will remove it. The unit is maintenance free and no consumables are required. Machine downtime is reduced and productivity increased.
