Hydrofarm Active Aqua Air Pump - 8 Outlet - 25 L/min (400 GPH) - 12W

Whisper-Quiet 8-Zone Aeration for Hydroponic Systems

The Hydrofarm Active Aqua Air Pump delivers 25 liters per minute (400 GPH) of adjustable airflow across eight independently usable outlets — all at a whisper-quiet noise level thanks to its super-silent multi-level muffler design. Running on just 12 watts at 120V/0.1A, it keeps energy costs low while delivering steady, reliable dissolved oxygen to reservoirs, water culture systems, and air stone arrays. Special artificial rubber internals maintain consistent pressure output and allow free adjustment from low to high without performance loss.

Key Features & Benefits

• 8 independently usable outlets — power up to eight air stones, diffusers, or manifolds simultaneously from a single pump.
• Super-silent multi-level muffler — dramatically reduces operational noise, making it suitable for grow rooms and indoor environments.
• Freely adjustable pressure — special artificial rubber components allow output pressure to be dialed up or down while maintaining a steady flow.
• Energy efficient — 12W draw at 120V/0.1A keeps electricity costs low even during 24/7 aeration cycles.
• 25 L/min (400 GPH) output — sufficient airflow to support multiple reservoirs, RDWC systems, or large air stone runs.
• Compact footprint — 7.1in L × 5.5in W × 11in H fits neatly in equipment areas without dominating bench space.

Who Should Use This

Deep water culture (DWC), recirculating deep water culture (RDWC), and reservoir-based growers who need reliable, quiet, multi-zone aeration without running separate pumps for each station.

Compatibility

Eight standard air outlets compatible with most 3/16in airline tubing and air stones. Requires 120V AC power supply.

Frequently Asked Questions

Can I run all 8 outlets at the same time?

Yes — the pump is rated to support all 8 outlets simultaneously, though individual outlet flow will vary based on back-pressure from air stones and tubing length.

How do I adjust the air pressure?

The pump includes a freely adjustable pressure control. Turn it to increase or reduce output across all outlets, then fine-tune each line with individual flow regulators as needed.

Is this pump suitable for continuous 24/7 operation?

Yes — it is designed for continuous duty use in hydroponic and aquatic aeration applications.

What size tubing fits the outlets?

Standard 3/16in (4-5mm) airline tubing fits directly onto each outlet barb without adapters.
