Danner Pondmaster AP-100 Pond Air Pump — 115V Oil‑Less, 9,150 cu in/min (150 L/min), 33-Outlet Manifold

The Danner Pondmaster AP-100 is a high-capacity, oil-less air pump engineered to deliver steady aeration for ponds and water features up to 11.5' deep.

Built for continuous use in a variety of aquatic systems, the AP-100 combines a quiet, energy-smart motor with a large output and multiple manifold outlets. It runs on standard 115V power, includes a six-foot cord, and is constructed without oil to reduce maintenance. For outdoor installations, place the pump inside a weatherproof enclosure to shield it from rain and debris.

How much air does this pump move and what does that mean for my pond?

The AP-100 produces approximately 9,150 cubic inches of air per minute (about 150 L/min), providing robust circulation for oxygen exchange and water movement. That volume supports aeration across multiple diffusers or fountains, helping maintain water quality and reducing stagnation.

• Air volume: 9,150 cu in/min (≈150 L/min)
• Pressure: up to 6.53 psi — suitable for many diffusers and shallow manifolds
• Maximum recommended water depth: 11.5 feet
• 33 manifold outlets to supply several air stones or devices

Is the AP-100 energy-efficient and quiet enough for yard installations?

The unit uses an oil-less motor designed for efficient power consumption and reduced upkeep. Noise output is rated around 45 dBA, which is comparable to a quiet office; this makes it reasonable for garden and backyard settings when placed inside a simple enclosure or equipment shed.

• Rated noise level: 45 dBA
• Power draw: 100 watts for continuous operation
• Oil-free design eliminates lubrication maintenance
• Recommended to enclose for outdoor sound dampening and weather protection

How do I connect and distribute air from the pump to my pond devices?

The AP-100 accepts standard tubing and can be extended using up to 3/4" I.D. tubing to reach distant manifolds. With 33 separate outlets on the manifold, you can feed multiple air stones, diffusers, or aeration loops; use check valves and proper fittings to balance flow and prevent backflow.

• Includes 33 manifold outlets for multi-point aeration
• Accepts up to 3/4" inner-diameter tubing for longer runs
• Use inline check valves and restrictors to equalize output if needed
• Compact footprint (11 3/4" x 8" x 8 7/8") fits inside enclosures or basements

What are the unit’s physical specs and installation considerations?

The AP-100 weighs about 16.5 pounds and is sized to sit on a level surface inside a ventilated box or equipment cabinet. It ships with a six-foot power cord; for outdoor use route the cord safely and obey local electrical codes. Elevating the pump slightly and providing vibration-damping feet will further reduce transmitted noise.

• Dimensions: 11 3/4" L x 8" W x 8 7/8" H
• Weight: 16.5 lbs for stable placement
• Standard 115V power, 6' cord included
• Ideal mounting: ventilated, weather-protective enclosure with vibration pads

Who this is for: The Danner Pondmaster AP-100 suits pond owners, koi and water garden hobbyists, and small commercial water feature operators who need a dependable, high-volume air source with many outlet options. It's a practical choice when you require continuous, low-maintenance aeration across multiple diffusers or zones, and when noise and energy efficiency matter in a backyard or landscaped setting.
