Hailea ACO Adjustable Air Pump — 0.4 to 42L/min Output

Hailea ACO Series Adjustable Air Pump — Single or Multi-Outlet Quiet Operation

The Hailea ACO Series is a lightweight, super-silent, high-performance air pump available in single or multi-outlet configurations. Delivers user-adjustable airflow from 0.4 up to 42 L/min, perfect for oxygenating nutrient reservoirs in DWC and recirculating systems. Low power consumption makes this affordable to run continuously, and the quiet operation suits domestic grow rooms where noise matters.

Why growers choose the Hailea ACO:

• Adjustable output 0.4–42 L/min — match airflow to airstone count and reservoir size
• Single or multi-outlet variants — pick the right configuration for your system
• Super silent operation — noticeably quieter than budget air pumps
• Lightweight, portable — easy to position anywhere convenient
• High-performance Hailea quality — proven brand, reliable build
• Low power consumption — cheap to run 24/7 continuously
• Perfect for nutrient reservoir oxygenation — DWC, recirculating systems, propagation

Who it's not for:

Match the pump output to your airstone count — undersized pumps leave airstones starved of air. Use a check valve in the airline if pump sits below reservoir level (prevents backflow flooding the pump). For very large commercial DWC, dedicated commercial blower pumps may be more efficient. Pair with a 4-way, 6-way, 8-way or 12-way manifold to split output across multiple airstones.
