Rena Air Pumps

Precisely engineered Rena air pumps minimize noise and vibrations for extremely quiet operation. Their curved casing and expansion chambers help absorb vibrations to significantly reduce noise output compared to standard air pumps. Careful fitting of the base further ensures soundproofing. Plus, they're powerful enough to maintain optimum flow rates under the greatest of depths, even with a clogged airstone. Rena's sleek, European, contoured design is available in a variety of sizes to suit most aquariums.

Features:

• Noise Suppression Chambers - Absorb vibrations caused by valve and air movement.
• Vibration Reduction Design - Traps vibrations caused by motor operation.
• Unique Precision Assembly - Base and housing are securely fitted to contain noise within the housing.
• Powerful Pump Technology - Produces maximum air output even in deep aquariums.
• Control Knob on Rena Air 200, 300, 400 - Adjustable airflow rate for custom control.
• Two Air Hose Outlets on the Rena 400 - Each controlled separately by its own air control knob.

NOTE: For indoor use only.

Care must be taken to prevent any back flow of water from entering the Rena Air pump when it is turned off. Water in the unit will cause damage or even render the unit inoperable. It is recommended that the unit be installed above the water level of the aquarium. However, the unit should not be placed where it could fall into the aquarium. If the unit is installed at or below the water level, the return of a check valve is highly recommended.

A drip-loop should be arranged to prevent water coming in contact with the electrical outlet. Once your air stone or air driven device is attached, plug the unit in to start the airflow. The Rena 200 & 300 Air Pumps are equipped with a control knob to adjust the airflow into the aquarium. The Rena 400 Air Pump is equipped with 2 control knobs to adjust the airflow into the aquarium.

Maintenance:
To maximize the output of your air pump, you should replace the diaphragm when you notice a drop in the airflow. Smoke and cooking oils can build up in the air pump and shorten the life of the interior parts, causing a drop in air flow. The air filter pad located on the bottom helps to protect and lengthen the life of these parts and should be replaced monthly.
