Key Features & Benefits

• 4-Way Air Distribution: Equipped with four durable, metal-tipped air nozzles that deliver 4 Liters per minute each. Easily power multiple aeration devices across a single massive tank, or split the airlines to oxygenate up to four separate aquariums at once.

• Precision Adjustable Airflow: The large, ergonomic rotary dial on the top of the unit gives you complete control over your air output. Seamlessly increase or decrease the intensity to perfectly match the specific surface agitation needs of your aquatic livestock.

• Advanced Noise Reduction: Engineered with a state-of-the-art air compressing system, internal shock-absorbing damping system, and a multilevel muffler. This ensures that despite its massive output, the pump operates with extremely low noise.

Installation & Safety Guidelines

To protect your investment and ensure the safety of your home, please strictly adhere to these setup instructions:

Crucial Setup & Safety Advice:

• Always Use Check Valves (Essential): If you position this air pump on a shelf or inside a cabinet that is below the water level of your aquariums, you must install non-return check valves on all four airline tubes. In the event of a power outage, these valves prevent aquarium water from siphoning backward down the tubes, which will flood your room and permanently destroy the pump motor.

• Above-Tank Placement: If you do not use check valves, you must securely position the air pump on a surface that sits higher than the highest water level of your aquariums to naturally prevent back-siphoning.

• Vibration Reduction: Ensure the pump rests flat on its rubber feet on a solid, level surface. Do not stretch the airline tubing too tight, as tension can transfer minor vibrations to the tank glass. Never submerge this pump in water.
