OIL FILTRATION SYSTEM"Miracle Boy" prevents deterioration of lubricating/hydraulic oil
Eliminating contaminating particles,
moisture and oxides all together
If the oil replacement is failed, the mechanicalequipment gets broken and stops its work. It isbecause the degrading factors which come up inoil decrease the oil performance.
Miracle Boy which was patented keeps the oil
performance at the new oil level or more.
The goal is to reduce a waste of work such assupport for sudden failure and raising operation
rates and reduce the running cost.
More than 10,000 units has been sold since 1970.

The reason why we need to replace oil.
(To run the machine at a high operating rate and to avoidtroubles)
Cracking on the internal
parts of the machine andclogging of the circuit
Rusting, viscosity changing,

Dust in oil

clogging due toemulsification

Moisturein oilOiloxidation

Wearing out of oil film
resulting in wear,
rust and viscosity change

3 advantages!

❶ Remove dust from oil

Keep oil which is used in the operated machine freshWith "Miracle Boy", your machine will be freefrom maintenance, not requiring oil❷ Remove moisture
To the level of ppm (0.0001%)
Remove emulsion too. Cloudy oil gets clear.

❸ Keep acid value

To the level of ppm(0.0001%)

Removedust

Absorb and filter oxidized sludge which occurs in oil
Removeselectively with using the patented technology and suppress
moisture
the increasing of the oxide level physically and safely withoutchemical materials.
The oil viscosity will not change by removal of malignant oxidized sludge.

To keep oil fresh

The oxide level hardlyRemoveoxidechanges after more than tenyears' use of oil.

Machine failures can be reduced to a minimum
under the condition oil is kept fresh,viscosity and moisture are at theappropriate level.
☑ Bearing will not break☑ Gear will not break☑ Hydraulic pump and solenoid valve will not break☑ Mechanical equipment will not break☑ Sudden failure will not happen☑ Wasted cost can be reduced☑ Productivity will improve

For various mechanical equipment"Miracle Boy" works offline with the machine oil tank.
Installation is easy.
Filter elements can be replaced without stopping theproduction line.

The multifunctional filter element eliminates
deterioration factors all together.

The filter element is divided into adsorption layers to remove very-fine particles,
moisture and oxidized sludge in oil. (W series do not remove moisture), and the element
traps contaminating particles in ㎛ increments.

Depth filtration(Depth type: Adsorption

Surface filtration(Surface type: Filtrationon the filter surface)

Oxidized sludge

Moisture
adsorption layer
Moisture
adsorption layer＊Each adsorption layer collects contaminants, oxides or moisture (Max. 1,000 cc/layer), trapping and removing the deterioration
factor until it becomes full (Maximum trap mass: Approx. 5,700 kg/layer).
＊The standard element corresponds to low-viscosity (VG2 -) to high-viscosity (VG460) hydraulic oil.
＊You can incinerate used elements and cases, which are made of inflammable materials.
＊Soluble additives (equivalent to oil molecule) contained in new oil are not eliminated.

Filtration precision
The high-precision element GE-21-SHG can be used for general mineral oil. Miracle Boy is adsorption-type filtration
device. The center of filtration accuracy distribution of GE-21-SHG is 3㎛, means it is designed to filter especially 3㎛ particles during adsorption 0.01~10~100㎛.
General mesh filter is replaced when it clogged. Against this, Miracle Boy is the special depth-type filtration and it
accumulate contaminations in the element. This great filter capacity is the reason why "we can keep oil fresh at thenew oil level or more.

Mechanism to remove oxidized sludge ➡ Viscosity invariance● GE-41-DC : For oil which is easy to oxidize under the high-temperature● GE-21-W4 : For water-glycol fluid which half consists of solution water to increase the flash point
for aluminum die casting machine, etc.
● GE-41-MR1 : For synthesized ester oil which is used for hydraulic control system of the power
plant steam turbine, the lubricant for jet engine, the latest aluminum die casting machine, etc.

Innovative!!

"Miracle Boy" contributes
to global greenhouse gas
reduction.

The appropriate disposal method is combustion (dumping in ocean and mountainis illegal). The amount of greenhouse gas which is caused by waste oil disposal is2,500kg.
Conventional oil maintenance
Purchase of oil
The operator stops the machine for oil
replacement.
Waste oil disposal
Burning of waste oil produces
greenhouse gas emissions.

machine at the paper factory

Below graph shows the analysis results of the oil contamination levels and the moisturelevels, total acid value since installed Miracle Boy in 1990. The contamination level is 33.3mg after one-year
operation without Miracle Boy. However, it decreased to 0.1mg by using Miracle Boy for one month. At thistime, the elements were replaced. One year after that, the contamination level increased to 0.6mg but
decreased to 0.2mg after the second elements replacement. Since then, the contamination level increases
and decreases depend on the timing of the element replacement. Nevertheless, the apex in the graph ishigher than that of the new oil on the market. No oil replacement for over 30 years with the better condition
than the new oil
