AC Infinity Hydroponics Air Pump for Reservoir Aeration
This is a small electromagnetic air pump that keeps bubbles moving through a reservoir or water-culture tank. Roots sitting in still water use up dissolved oxygen quickly, and warm water holds less of it to begin with. It is rated at 45 GPH (2.8 L/min) through 2 outlets, and it draws just 4W on 110V AC. At that draw, running it around the clock barely registers on a power bill. A turn dial on the front adjusts air pressure from low to high, which helps when a shallow tank does not need full flow. Each outlet feeds its own line, so one pump can serve two buckets or two stones in one reservoir. The box holds 2 air stones at 1.88 in, 2 air tubes at 78.74 in and 2 check valves. Cut the tube about 6 in from the pump and fit the check valve with its arrow pointing away from the pump. That one step keeps water from running back during a power cut.
Setting Up This Hydroponic Air Pump Kit
Placement matters more than people expect. Set the pump on a shelf or bench above the water line, then run the tubing down to the stones. Keep the intake vent below the control knob clear, because a blocked vent starves the pump of air. The heavy shell and internal muffler keep it quiet, though a hard shelf can still pick up a little hum. A folded towel or rubber pad under the feet takes care of that. This size suits DWC buckets, small reservoirs, aquaponics tanks and aquariums, not a large recirculating system. Larger air stones ask for more volume, so check the bubble pattern after you change stones. Pull the stones out and let them dry when the pump sits idle between runs. Stones clog over time from salts and biofilm, so a soak between crops keeps them working. The body is not waterproof, and the warranty excludes submersion, so keep it out of spill range. Two years of coverage comes standard against manufacturing defects.
Key Features
- Two independent outlets: Each line runs its own stone, so one pump can serve two buckets.
- Low power draw: The electromagnetic motor is efficient enough to run continuously without adding much to the bill.
- Adjustable dial: Dial pressure down for shallow tanks or small stones and up for a deeper reservoir.
- Complete aeration kit: Stones, tubing and check valves are in the box, so setup needs nothing extra.
- Check valve protection: One-way valves keep water from running back toward the pump.
- Muffled shell: A heavy body and multi-layer muffler keep noise down for rooms people work in.
- Two-year warranty: Coverage applies to manufacturing defects for two years.
