Thruster Filters

Thruster Filters from CJC® dry, clean and maintain your gear oil quickly and cost-effectively. Whether fixed propeller or variable pitch propeller, whether fishing boat or container ship, whether mineral oil or biodegradable lubricant, CJC® Thruster Filters are precisely configurable for your ship. Installed in the offline or lube oil circuit, they continuously ensure maximum oil cleanliness. They remove water, wear particles, oil degradation products and acids — even microbial infestation — efficiently and reliably.

How you benefit from installing a CJC® Thruster Filter

  • You save the gear oil – even if it contains a lot of water – and you achieve a longer service life for the oil filling.

  • You ensure maximum wear protection and save time and money during maintenance and repair.

  • You minimize unplanned downtimes and off-hire times for more reliability and availability of your vessel.

  • You ensure the highest possible oil cleanliness and thus provide manoeuvrability at all times.

Product Advantages — CJC® Thruster Filters

Thruster-Filter, Allrounder

Flexible all-rounder

CJC® Thruster-Filter dry each gear oil independent from additives, viscosity and air content in the oil. Optionally with oil sensors for integration into your condition monitoring system.

Thruster-Filter, Maximum oil cleanliness

Maximum oil cleanliness

Clean and dry gear oil within a very short time. The CJC® Thruster Filter removes all contaminants – independently, continuously and highly efficiently. For maximum service life of oil filling and thruster components.

Thruster-Filter, Economical & ecological

Economical & ecological

Depth filter made of 100% natural fibers — 0% plastic and 0% metals. High recording capacities and thus long filter life ensure excellent price-filter performance of the CJC® Thruster Filters.

Thruster-Filter, Easy installation & maintenance

Easy installation & maintenance

Easy and flexibel installable in an independent circuit — e. g. as offline filter. Filter change is possible during thruster operation. Low-maintenance, robust and durable, the CJC® Thruster Filter also convinces.

Details about your products — CJC® Thruster Filter

The various concepts for the dewatering, filtration and care of gear oil, as well as the modular design, make it possible to adapt our thruster filters individually to your stern or bow thruster. They are ideal for counteracting the continuous ingress of water into thrusters and keeping the gear oil consistently dry and clean — free of water, particles and oxidation residues. For decades, we have documented the oil cleanliness achieved on various thruster drives and vessel types. Achieve a longer service life for your thruster drives quickly, efficiently and cost-effectively and avoid unnecessary failures and off-hire times for a more economical operation.
