The JBL ProAir a200 is the right choice when more air output and, above all, more pressure reserve are required - e.g., for deeper aquariums, fine air diffusers, or air-driven filters/air lifters that generate higher back pressure. With a flow rate of 200 l/h and > 130 mbar, it is significantly more powerful than the smaller models while remaining efficient (3.2 W). The air volume is electrically controlled so that the bubble pattern and surface movement can be adjusted to suit the stock and situation (e.g., at night). Recommended for approx. 90-300 l, the acoustic level is 43 dB(A) (at 1 l/min).
