The JBL ProAir a100 is the next step up in performance within the ProAir series and is recommended for aquariums that require noticeably more powerful aeration - for example, those with a higher stocking density, warm temperatures, or at night to stabilize the oxygen balance. With a flow rate of 100 l/h at > 80 mbar and only 2.5 W, it is efficiently dimensioned and designed for tanks of approx. 60-200 l. The air volume can be adjusted as required (from a100), allowing the surface movement and bubble formation to be specifically adjusted. Sound-absorbing construction and vibration-damping feet ensure quiet continuous operation, the noise level is 39 dB(A).
