Hailea ACO Series Adjustable Air Pump for Hydroponics

Dial In Exactly the Oxygen Your Reservoir Needs

The Hailea ACO Series is a lightweight, super silent diaphragm air pump for oxygenating nutrient reservoirs, adjustable from 0.4 up to 42 litres per minute from the control on top. Most growers either drown a small tank in turbulence or starve a big one - this lets you set the air to the tank. Models run single or multi-outlet, draw 2 to 18 Watts, and sit on suspension feet, with air passing through an internal muffler on the way out.

Key Benefits

• Adjustable 0.4 to 42 L/min - match the air to the tank, not the other way round.
• Genuinely quiet - internal muffler and rubber feet keep noise and vibration down.
• Low running cost - 2W to 18W depending on model, running continuously.
• Single or multi-outlet - feed one stone or a bank across a multi-pot system.
• Steady pressure - the oscillating diaphragm gives consistent, even output.

Warm, Flat Solution and Roots That Never Get Going

An under-aerated tank quietly costs you the grow. Dissolved oxygen falls away, roots discolour, poor nutrient uptake sets in, and you are left with slow growth and low yields that look like a feed problem but are not. Being able to wind output up as root mass fills out means one pump covers propagation through to a fully loaded reservoir.

How to Use

• Siting: flat surface near the reservoir and above the water line so solution cannot siphon back.
• Connection: fit airline to the outlet, push an airstone on the far end and submerge it.
• Setting output: adjust the top control until bubbling is steady without splashing the lid.
• Multi-outlet models: spread stones evenly, or run one per DWC pot.
• Run time: leave it running continuously - aeration should never be timed.
• Maintenance: keep the underside air intake clear and check stones for clogging.
