New addition to Centriguard filter line - filtration - Brief Article

Diesel Progress North American Edition, Feb, 2004

Fleetguard also recently released a new model in its Centriguard centrifugal lube filtration system family. The CH41111 centrifuge, which incorporates the patented SpiraTec teclmology, is designed for 8L to 30L engines. Larger engines can be accommodated by the use of multiple milts, the company said.

The CH41111 centrifuge has a IL capacity and offers up to 50% reduction in soot levels--a significant improvement over conventional centrifuge designs, the company said.

The Centriguard units were first introduced in the 1990s. This newest model combines a split-flow design, combined with the SpiraTec spiral vane technology to provide high soot removal efficiency. "These advancements ensure better performance than an empty rotor, since the empty rotor's performance is fixed and lower than Fleetguard's latest technology," said John Clevenger, director of product management at Fleetguard.

The series includes the CH41111 Remote Mount Gravity Drain System and the CH41112 Remote Mount Air Assisted Drain System. The system is designed to reduce cylinder liner polishing and valve bridge/rocker arm wear caused by accumulation of particles smaller than five microns. This requires higher efficiencies at smaller micron sizes with a greater capacity. SpiraTec technology effectively removes these tiny particles, while extending full flow service intervals (depending on severity of duty cycles) and improving oil viscosity and fuel economy, the company said.

The CH4111's performance can be customized for a specific OEM need, the company said. Other benefits include reduced operating costs through extended service reduced replacement part cost and lower labor cost to service. Environmental waste is also reduced because the system is disposable and incinerable. "We ensured that the design has minimal environmental impact," said Clevenger, "because that is a critical issue to our customers and to our company."
