Filter
The Gen-Kleen II from Centek Industries is a compact, purpose-built exhaust filter designed for marine generators and onboard gensets. It captures hydrocarbons and other pollutants from generator exhaust discharge so only clean water is returned overboard, helping eliminate the oily sheen that can form around a boat while its generator is running. That combination of reduced visual pollution and improved water quality makes it a practical addition for boat owners who operate generators frequently or are concerned about marina and coastal water cleanliness.
Built to fit tight installations, the Gen-Kleen II measures 28 inches high by 25 inches wide by 25 inches deep. Its size and boxed footprint allow it to be mounted in spaces where larger systems would not fit, making it suitable for a wide range of recreational and commercial vessels. Centek’s patented filter media is engineered to capture hydrocarbons and other soluble and insoluble contaminants from the generator’s wet exhaust stream so discharge leaving the vessel is visibly clear and free of surface sheen.
The unit is described by the manufacturer as a practical retrofit for existing genset installations or as original equipment in new fit-outs. Because it treats exhaust discharge at the point where generator coolant and exhaust mix, the Gen-Kleen II prevents hydrocarbon-laden water from entering the surrounding waters, which is particularly important in harbors, marinas and environmentally sensitive areas. The design emphasizes straightforward integration and minimal footprint rather than extensive plumbing or structural modification.
Owners and operators should expect routine attention to the filter as part of normal vessel maintenance. Like all filtration systems used in marine environments, the Gen-Kleen II requires periodic inspection and servicing of its filter elements to maintain performance. Regular servicing ensures the filter continues to capture contaminants effectively, preserves the expected discharge quality, and helps avoid operational issues downline in the exhaust or bilge systems. Centek provides replacement parts and service guidance to support ongoing use.
Beyond its environmental benefits, the Gen-Kleen II can also contribute to a cleaner appearance around a vessel at anchor or under way. Eliminating the rainbow-like sheen commonly observed when a generator runs through a small bilge or hull outlet improves the experience for owners, guests and nearby boaters. For operators whose vessels use marinas, yacht clubs or commercial berths, the reduction in visible oil or hydrocarbon residue can also help address local rules or expectations about keeping shared waters free of contamination.
The manufacturer lists a starting MSRP of $3,995. For purchasing inquiries, installations or technical questions, Centek Industries can be reached by phone at (229) 228-7653. Additional product details and support information are available directly from the manufacturer. www.centekindustries.com
The Gen-Kleen II represents a straightforward approach to a common onboard concern: managing generator exhaust discharge so it does not leave a visible sheen or contribute unnecessary hydrocarbons to the water. Its compact dimensions, patented filtration approach and emphasis on ease of installation make it a practical option for many boats and small commercial craft that rely on gensets for power.
When evaluating exhaust filtration solutions, consider the physical footprint of the unit, how it will be routed into existing exhaust and cooling systems, and the manufacturer’s guidance for routine service and part replacement. Properly installed and maintained, a dedicated exhaust filter like the Gen-Kleen II can reduce the environmental footprint of onboard power generation while keeping the area around the vessel looking cleaner and more professional.
