CT‑101B – adjustable aerator

This SunSun CT-101B is an adjustable air pump for aquarium keepers who need reliable aeration in their tanks. Gas exchange in an aquarium consumes oxygen and releases CO2, and excess CO2 can harm fish and plants. This pump adds air to the water so that oxygen levels stay adequate and pH remains stable.

Why it matters

• Adjustable output: Power is regulated steadily, so the oxygen and CO2 balance can be fine-tuned for the tank.
• Low power draw: The manufacturer attributes the 3.5 W consumption to a more efficient electromagnet coil with more windings in the same volume.
• Vibration control: Soft rubber feet and a rubber hanger keep vibrations from transferring to the surface the pump sits on or hangs from.
• Wear-resistant parts: The manufacturer uses a titanium alloy connecting pin between the electromagnet and the diaphragm, and a diaphragm made from a proprietary elastic material.

Specifications

• Power consumption: 3.5 W
• Pressure: 0.016 MPa
• Output: 2.5 l/min
• Number of outlets: 1

What it works with

The pump is designed for aquarium aeration and fits into the aquatic filtration and aeration category. With a single outlet and 2.5 l/min output, it suits setups that need one air line for gas exchange. Its adjustable output lets the keeper match the airflow to the tank's needs.
