S-4000B 5W

Boyu S-4000B 5W is the flagship model for high-volume oxygenation. It features an analog dial to regulate air flow on 4 simultaneous outlets, providing stunning micro-bubble barriers and lowering harmful CO2 concentrations in dense tanks. Ideal for collectors or those who own multiple nearby aquariums, it allows you to finely regulate the amount of air delivered. Its pressure stability ensures fine and constant bubbles even at significant depths.
