BPS Marine BPS-4 4-Transducer Ultrasonic Antifouling System - 12VDC

The BPS Marine BPS-4 4-Transducer Ultrasonic Antifouling System is engineered to protect your hull, through-hull fittings, and intake systems from marine growth without chemicals or moving parts. After decades on the water, any serious boater knows that biofouling—barnacles, mussels, algae, and slime—degrades hull performance, increases fuel consumption, and can block cooling intakes. This ultrasonic system operates silently and continuously at 12VDC, delivering the protection you need whether you're running a saltwater center console, freshwater cruiser, or commercial fishing vessel.

The four-transducer array generates ultrasonic waves that create an inhospitable environment for larval organisms and fouling species, preventing settlement before it starts. Unlike biocide coatings that wear away or require frequent reapplication, this system provides year-round, maintenance-free protection by emitting continuously whenever 12VDC power is available. The transducers are designed for durability in harsh saltwater and freshwater environments, and the compact unit integrates easily into existing electrical systems without requiring hull modifications or invasive installation procedures.

This antifouling system is ideal for vessels that spend extended time in port or cruising waters where biofouling accelerates, including commercial fishing boats, charter operations, and liveaboards. Installation is straightforward—mount the unit securely and connect it to your vessel's 12-volt DC system. The BPS-4 works across freshwater, brackish, and saltwater environments, making it a versatile solution for boaters operating in multiple regions who want to eliminate the cost and labor of regular hull cleaning and haul-outs.
