SunSun CT-201 Adjustable Silent Air Pump

Give your aquarium the oxygen-rich environment it deserves—without the noise. The SunSun CT-201 Air Pump is built for modern aquarists who want silent operation, steady airflow, and full control, making it ideal for small to medium tanks up to 75 liters.

Key Features & Benefits

• Whisper-Quiet Operation – Double-layer sound insulation + vibration-dampening feet ensure near-silent performance

• Energy Efficient (4W) – Designed for 24/7 use without high electricity cost

• Steady Pressure Output – Maintains consistent airflow (0.012 MPa) for reliable aeration

• Compact & Sleek Design – Minimalist build that fits neatly behind or inside setups
