“Easy-service” centrifugal oil filter launched for diesel engines by MANN

MANN+HUMMEL has innovated a new, easy-service centrifugal oil filter.

Excess oil removal reduced to 10 minutes and technicians only need to remove rotor lining for cleaning

MANN+HUMMEL has responded to consumer requests and demand by launching a new-generation centrafugal oil filter, which is said to dismiss the need for technicians to use tools when servicing and substantially reduce servicing times.

The company has said in future, when cleaning the rotor of a centrifuge, service technicians will be able to put the heavy wrench to one side, provided they are servicing the new ESC (Easy Service Centrifuge) 600 from MANN+HUMMEL.

For this service-friendly solution, staff changed the design to ensure that servicing is easy, clean and quick.

The concept sets the standard for future developments, MANN+HUMMEL has confirmed.

In a statement, the company explained why they believe their new filter solution allows for longer gaps between service intervals. MANN+HUMMEL said: “Marine and hauling truck applications require high performance and maximum reliability under the most extreme operating conditions.

“This is also true for the filtration solutions which find application.

“The centrifuge range from MANN+HUMMEL reliably retain contaminants from the lubrication oil used in diesel engines in the partial flow and therefore contribute towards a considerably longer service interval.

“In this process, the contaminated oil passes through the centrifuge.

“The oil pressure causes the rotor to revolve at high speed and the resulting centrifugal forces dirt particles to separate from the oil.

“They are pressed against the inside walls of the rotor where they accumulate over time to form a thick filter cake.

“The cleaned oil then flows back to the oil sump of the engine.

“Easy to service”

“Numerous users have relied on the efficiency of this separation solution for many years.

“The only thing which was missing was an easy servicing concept.

“This is a requirement which MANN+HUMMEL has now fulfilled with the ESC 600.

Integrated handle

“Handling is improved through the integrated handle in the new single-part die-cast cover which simplifies removal.

“The lower lip seal is designed to be non-drip, which enables better sealing and prevents visible spillage.

“In order to easily remove the filter cake, the housing can be opened by releasing the bayonet lock without the need for tools while the low-weight rotor made from plastic reinforced with glass fiber remains in the centrifuge.

Remove excess oil in 10 minutes

“The service technicians only have to remove the rotor liner for the purpose of cleaning.

“This is made from durable silicone and after removal of the filter cake it can be reused a number of times.

“Finally, a new dump valve reduces the time to remove the excess oil compared to a conventional drain valve from 45 minutes down to only 10 minutes.

“As a result, the rotor liner can be removed very quickly.”

The easy-service centrifuge was originally developed for marine applications, but can also find application in off-highway trucks like mine haul trucks, power generation and genset units as well as trains.

In order to additionally extend the range of applications for this concept with considerably lower servicing costs, MANN+HUMMEL will expand the series with an ESC 200 and an ESC 400.
