LOUISVILLE, Ky. – A new, heavy-duty spin-on by-pass filter from Luber-finer promises to reduce the added soot and neutralize the acid contaminants that can destroy vital engine parts in today’s emission-compliant engines, according to company officials who were at the Mid-America Trucking Show.

The Zgard LFP9750 by-pass filter uses filtration technology to protect the buffers in engine lubricating oil additive packages, increase corrosion resistance and reduce soot concentration levels.

That means less frequent drain intervals and longer life for emission-compliant engines, say Luber-finer officials.

Field tests showed the Zgard filter maintained the soot level below three per cent though 300 hours. This compared to the test fleet’s recommended field replacement of four per cent soot oil or 300 hours.

And other tests concluded the Zgard can extend oil drain intervals by up to 75 per cent.

The filter is configured to operate in a by-pass filtration mode and employs a louvered Zinc alloy sheet, co-pleated with a synthetic blend media to filter heavy soot and neutralize acid.

The composite filter media neutralizes oxidized nitrogen and sulfur components in lubricating oil.

Company officials say it also removes corrosive pressure from oil additives and sensitive metal surfaces.

The filter can remove damaging particles of less than one micron, company officials claim.

The by-pass filter uses a double-filtration design to increase overall capacity – it can hold more contaminants compared to full flow filters, it is claimed.

It also includes a new spin-on design for easy installation and removal.
