CT‑202 – adjustable aerator

This adjustable air pump is intended for aquarium keepers who need reliable aeration with two outlets. Aeration supports gas exchange in the water, which matters when fish and plants produce carbon dioxide and the water needs fresh oxygen. The pump's stepless power control lets the keeper set the air output to the actual needs of the aquarium.

Why it matters

• Stepless power control: the output can be adjusted smoothly, so the air flow can be matched to the tank rather than running at a fixed level.
• Two outlets: the pump supplies two air lines at 2 x 1.5 L/min, so two points in the aquarium can be aerated from a single unit.
• Titanium alloy pin: the pin connecting the electromagnet to the membrane is made of a titanium alloy, which the manufacturer describes as heat resistant and considerably lighter than standard parts.
• Low-vibration mounting: soft rubber feet and a rubber hanger reduce the transfer of vibration to the surface the pump stands on or hangs from.

What it works with

The CT-202 is classified in the aquatic category as an aquarium air pump, so it is used for aerating freshwater or aquarium setups rather than terrariums. Its 2 x 1.5 L/min output and 0.015 MPa pressure are the parameters to check against the volume and depth of the tank. The pump can be combined with airstones or other air-line accessories that work with its two outlets.
