Q Will fitment of
a centrifuge affect the lube oil pressure on my engine?
A No. Almost all medium
to high-speed diesel engines have minimum surplus to
requirements oil pressure at lube pump in excess of
30%. The Mann+Hummel centrifuge takes up to a maximum
of 10% of the engine oil pump output.
Therefore it is important to use the correct SPINNA
for the application. |

Q Will the centrifuge
remove the additives in the oil?
A No. All additives are in
solution. The centrifuge at best creates G forces of around
3,000 times the force of gravity and cannot remove additives,
it is like sugar mixed with coffee, it cannot be removed.
Spent additives, when mixed with soot become additional
wear particles and contribute to oil thickening. Only
spent additive package in lubricating oil is removed along
with soot and other debris by the spinna. It’s to
be remembered that additives deplete, that’s why
we change oil. It is also a known fact that the dirtier
the oil the quicker the additive pack will destruct. This
explains why engine oil burn often stops or decreases
and oil lasts longer after fitting a spinna. |

Q If I fit a centrifuge
do I still need a full flow filter or a by-pass filter?
A A full flow filter is a
barrier filter, it stops large particles and should be
left on the engine. Certain engine manufacturers fit a
by-pass filter to tackle small damaging particles. The
best by-pass filter can only filter down to around 10
microns. Most are around 20 microns. When you fit a Mann+Hummel
centrifuge you must remove any additional by-pass filter
unless it is incorporated in the full flow filter, because
collectively they could affect the oil pressure. As the
centrifuge is the superior cleaner, extracting dirt particles
less than 1 micron, there is not need to have both. This
results in an added economy and extends oil life. |

Q Why is lube oil type
and temperature so important?
A The perfect installation
for the fitment of Mann+Hummel centrifuge to an engine
is with an oil specification of SAE30 or multigrade with
a temperature of 75% or higher. At 75% on a SAE30 = 25CST
this low viscosity through the centrifuge will create
greater rotational speed as there is less restriction.
In conclusion, the hotter the oil the thinner the oil
the better the separation. The cleaner the oil the longer
engine componentry life, which results in substantial
$avings in rebuilds and down time and of course dollars
and cents. The better the oil quality, the better the
result. |

Q Can the Centrifuge
remove soot?
A The Mann+Hummel Centrifuge
has an excellent track record in controlling soot. Today’s
modern diesel engines all suffer from some sort of soot
related problems, some much more than others. When soot
is present in lube oil and not removed, not only will
you see oil thickening but the soot has the ability to
attack the ZDDP antiwear additive resulting in premature
breakdown of the oil, there is nothing in the market place
designed to totally address soot related problems. The
Mann+Hummel centrifuge is widely accepted as the industry
leader world wide for maintaining traditional oil change
intervals. Also with Quality oil sampling, many spinna
users can substantially extend oil & filter change
intervals within the boundaries of OEM oil cleanliness
parameters. |

Q Can the centrifuge
contribute in any way to destructing my engine?
A Definitely not, the centrifuge
has a preset cut off valve set at approximately 20psi.
It cannot function under that pressure. If the engine
oil pump became weak or ceased to work, once the pressure
dropped to less than 20 psi the centrifuge would cut off
oil supply. Therefore the spinna can never contribute
to engine failure, that factor is one of the significant
reasons why the spinna enjoys support of now 52 engine
manufacturers worldwide |
