Description
Hailea Adjustable 2-Outlet Air Pump is a compact, energy-efficient aeration pump that we have been supplying to UK hydroponic growers since 2017 for oxygenating small to medium reservoirs, propagation trays and individual DWC buckets. With two independently adjustable outlets, the Hailea 2-outlet pump gives you precise control over airflow distribution — an advantage over fixed single-outlet pumps when you need to balance aeration between two separate zones, reservoirs or DWC containers of different volumes.
Why Adjustable Outlets Make a Difference
In a standard two-outlet air pump, both outlets deliver the same airflow regardless of the differing needs of two zones. If you are aerating both a 30-litre propagation reservoir and a 100-litre main nutrient reservoir from a single pump, fixed equal-flow outlets will over-aerate the small reservoir while under-serving the large one. The Hailea adjustable 2-outlet design puts a needle valve on each outlet, letting you throttle each independently — so you can deliver gentle aeration to the propagation side and full output to the main reservoir simultaneously. This flexibility makes the pump far more versatile across different setups and growing stages than a fixed-output equivalent. The electromagnetic diaphragm mechanism provides quiet, reliable continuous operation without the heat or maintenance demands of rotary compressors.
Setup, Positioning and Maintenance
Position the pump above reservoir water level and fit non-return valves on both outlet lines to prevent back-siphon during power loss. Connect to standard 4mm air tubing and place air stones on the reservoir floor. Set each outlet to the required flow rate using the needle valve adjustment. Replace air stones every 3–6 months as calcium deposits reduce output. For reservoirs above 100 litres, upgrade to the Hailea 8-outlet adjustable pump or Hailea V30/V60 for higher-volume oxygenation. Pair with a Newa Therm heater for complete reservoir environmental management.
