OXYBOOST PLUS APR‑300 – aerator

The OXYBOOST PLUS APR-300 is a membrane air pump for aquarists keeping tanks in the 200–300 L range who need two air outlets from a single unit. It delivers up to 2 x 150 L/h, so it can supply two separate air lines or airstones in one setup.

Why it matters

• Two outlets: the APR-300 model has two air outlets, which allows two independent air lines to run from one device.
• Stepless regulation: the APR models are adjusted with ergonomic knobs on the top of the housing, so airflow can be set smoothly rather than in fixed steps.
• Quiet operation: the pump runs quietly, which matters in living rooms and bedrooms where tanks are often placed.
• Low power consumption: 2.5 W for 2 x 150 L/h output keeps energy use low for continuous operation.
• Easy cleaning: the rounded, disc-like housing has few edges to collect dust and dirt.

What it works with

The APR-300 suits freshwater and marine tanks in the 200–300 L capacity range that need aeration or water movement from two points. Its two outlets and 4/6 mm hose connection make it practical for splitting air between a sponge filter, an airstone, or a decorative element. Check the hose and valve compatibility with your existing setup before installation.
