Pondmaster AP-100 Air Pump

Pondmaster AP-100 Air Pump

Maximum Oxygenation for Large Lakes, Koi Ponds & Professional Aquatic Systems

The Pondmaster AP-100 is the most powerful model in the AP-Series, engineered for large-scale water features, commercial hatcheries, and expansive koi ponds up to 7,500 gallons. High-volume aeration is the most effective way to ensure a healthy habitat by increasing dissolved oxygen levels, especially during hot summer months or deep winter freezes.

With a heavy-duty motor that outputs a staggering 8,900 cubic inches of air per minute, the AP-100 can push vital oxygen down to depths of 11.6 feet. Despite its massive power, it remains remarkably efficient at 100 watts and maintains a quiet operational profile (45 dba). Its oil-free design ensures your water remains pure and free from mechanical contaminants.

Key Features:

• Industrial-Grade Airflow: Delivers a massive 8,900 cu.in/min to meet the demands of very large or heavily stocked aquatic environments.

• Superior Depth Performance: The highest pressure rating in the series, maintaining strong bubbles at depths over 11.5 feet.

• Energy-Efficient Heavyweight: Provides maximum aeration with a relatively low 100-watt power draw.

• Whisper-Quiet Performance: Engineered for low vibration and noise, operating at only 45 decibels—barely audible from a short distance.

• Safe & Oil-Free: Non-oil lubricated motor is safe for fish, plants, and the environment.

• Durable Construction: Built for 24/7 continuous operation in professional and residential settings.

Ideal For:

• Extra-large koi ponds and water gardens up to 7,500 gallons.

• Deep-water aeration for small lakes or deep ponds.

• Professional fish farming, hatcheries, and multi-tank retail displays.

Installation Note: The AP-100 is not submersible. To maximize the life of the motor, house the pump in a dry, ventilated area. For outdoor installations, a protective, weather-proof cover is required to shield the unit from rain and debris. Always ensure the pump is positioned above the water level to prevent back-siphoning.

Maintenance Tip: Due to the high volume of air processed, check the intake filter monthly in dusty environments. Keeping the filter clean prevents the motor from overheating and maintains maximum PSI. Replacement Diaphragm Kits are available to keep your AP-100 running like new for years.
