Avoid oil changes, repair costs and “off-hire” times
Thruster filters from CJC®: Your solution for consistently dry and clean oil
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
Product Advantages — CJC® Thruster Filters
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.
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.
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.
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.

Customer cases
Find out in our application studies how operators benefit from the installation of the CJC® thruster filters.
“Only with the CJC® Thruster Filter could the transmission oil finally be dried satisfactorily. Without CJC®, we would have had to change the 1,500 litres of transmission oil soon. By avoiding the oil change, we were able to save 4,890 EUR (3.26 EUR/litre) – an important contribution not only in terms of budget, but also in terms of resource conservation. The excellent results convinced us, so that we decided to purchase two identical CJC® systems for our tugs “Bugsier-5” and “Bugsier-6”.
“The CJC® Thruster Filter allows us to remain the tug in operation for 6 months before its next technical shutdown. The results of the oil analyses are clear and clearly demonstrate the effectiveness of the CJC® Thruster Filter.”
„After having tested nearly every piece of water removing equipment on the market in order to solve our water and contamination problem, we went for the CJC® Thruster Filters, because it was simply the best. The filters did the job to our greatest satisfaction, removing particles, water and other waste products. CJC® Thruster Filters for oil maintenance are a very good investment. The return of investment is very short.“
