Hailea ACO-9902 Aquarium Air Pump (2.5W) – Single Outlet Oxygenator

Hailea ACO-9902 Aquarium Air Pump (2.5W) – Energy Efficient Single Outlet Oxygenator

Ensure your aquatic pets thrive in a healthy, highly oxygenated environment with the reliable Hailea ACO-9902 Aquarium Air Pump. Manufactured by HAILEA, a globally trusted aquatic brand established in 1989, this robust pump delivers consistent and powerful aeration to keep your fish active and your water parameters stable.

Housed in a sleek, minimalist black casing, the ACO-9902 is designed for outstanding daily utility. Operating on an ultra-efficient 2.5-Watt motor, it provides a steady airflow of 2.5 Liters per minute, making it the perfect engine for driving air stones, sponge filters, or action ornaments in small to medium-sized freshwater and marine setups.

Key Features & Benefits

• Energy Efficient Aeration: Consumes only 2.5W of electricity while delivering a reliable 2.5 L/min output, ensuring your tank stays heavily oxygenated without raising your monthly energy bill.

• Vibration Dampening Design: Built with a heavy-duty, integrated rubberized base pad that actively absorbs internal motor vibrations, keeping operation smooth and minimizing annoying rattling noises against your aquarium stand.

• Trusted Manufacturing: Engineered by an ISO9001:2000, ISO14001, and OHSAS18001 certified manufacturer, guaranteeing a high-quality, durable build that you can depend on for continuous 24/7 use.

• Single Outlet Efficiency: Equipped with a single white air nozzle that easily connects to standard 4mm aquarium airline tubing for a quick and straightforward installation.

• Versatile Expansion: While it features a single primary output, the manufacturer's "Installation & Connection" guide perfectly illustrates how the pump can be paired with external air valves to easily split the airflow and drive multiple air stones simultaneously.

Setup & Safety Guidelines

To maximize the lifespan of your Hailea air pump and protect your aquarium, please follow these standard industry practices:

1. Placement: Always place the air pump on a dry surface above the highest water level of your aquarium.

2. Use a Check Valve: If you must place the pump below the water line (such as inside a cabinet stand), you must install a non-return check valve on the airline tubing. This critical step prevents water from siphoning backward into the motor during a power outage, which would permanently damage the unit.

3. Routine Maintenance: Inspect and replace your air stones regularly. Mineral buildup and algae can clog air stones over time, creating back-pressure that forces the pump to work harder and wears out the internal rubber diaphragms.
