Hailea Air Pumps

Adjustable air pumps sized for every reservoir

Hailea Air Pumps cover the everyday grow-room aeration duties, from a single-outlet model putting out 1.6 litres per minute, up to a four-outlet model moving 4 x 2.5 litres per minute - so there's a match for anything from a propagator to a small RDWC line. Every model uses Hailea's adjustable diaphragm design with a multi-level muffler and suspension feet, letting you turn output up or down without a big jump in running cost or noise.

Struggling to keep every bucket in an RDWC system evenly oxygenated?

Uneven aeration usually shows up as one or two plants lagging behind the rest, with slower roots and patchier feeding than their neighbours. Choosing a pump with enough outlets and adjustable output for the whole system - rather than daisy-chaining stones off an undersized pump - keeps dissolved oxygen consistent bucket to bucket.

Key Benefits

• Adjustable output matches air flow to the number of stones in use
• 1, 2 or 4 outlets for one bucket up to a small RDWC line
• Low power draw for a pump that runs around the clock
• Multi-level muffler and suspension feet for quiet, low-vibration running
• Under 45dB across the range for occupied living spaces

How to Use

• Pick a model with at least one outlet per air stone you plan to run
• Stand the pump above the water line, or fit check valves, to stop back-siphoning
• Connect airline to each outlet and its stone or diffuser
• Turn the dial up gradually until every stone gives a steady curtain of bubbles
• Check each bucket on multi-outlet models so output stays balanced
