Air pump Tetra AirSilent Maxi by Tetra — aquarium air pump, model AirSilent Maxi

Tetra AirSilent Maxi is an aquarium air pump engineered to supply continuous and stable aeration for freshwater and marine aquariums. Designed for larger tanks, it provides an even airflow to support sponge filters, air-driven ornaments and general oxygenation. The unit operates at low noise levels suitable for home and office environments while helping maintain biological filtration and improved water circulation across the aquarium.

Advantages

The AirSilent Maxi delivers a steady airflow with minimal vibration and reduced operating noise thanks to sound-dampening design features. Its consistent performance supports long-term operation for extended filter runs and air-powered devices. The pump is easy to install, compatible with standard airline tubing and offers reliable pressure to distribute air to multiple outputs when needed.

Suitable for

• Aeration of medium to large freshwater aquariums
• Marine tanks requiring continuous oxygen supply
• Driving sponge filters and undergravel filtration systems
• Powering air-driven ornaments and bubble walls

Key specifications

• Intended use: aquarium aeration for freshwater and marine environments
• Noise level: low operating noise designed for domestic environments
• Air delivery: steady, continuous airflow suitable for filters and ornaments
• Design features: vibration damping and sound reduction elements
• Compatibility: works with standard aquarium airline tubing and common air accessories

How to use

Place the pump on a stable, level surface above or below the aquarium as recommended by the manufacturer, ensuring the unit remains dry and well-ventilated. Connect standard airline tubing from the pump's outlet(s) to the sponge filter, air stone or ornament, keeping tubing runs as short and straight as practical to maintain airflow. If air distribution to multiple devices is required, use a suitable manifold or multi-outlet valve. Power the pump using the provided mains lead and check airflow after start-up; adjust or add check valves and flow control accessories if backflow or uneven distribution is observed.

Usage recommendations

For reliable long-term operation, maintain the pump by periodically checking airline tubing for kinks or blockages, replacing worn valves or tubing, and positioning the unit to avoid exposure to splashes. If quieter operation is needed, place the pump on a soft anti-vibration pad and ensure it is not in direct contact with hard surfaces that can amplify sound.
