Description
Quiet diaphragm air pumps with the manifold in the box
The Hailea V Series is a compact diaphragm air compressor in a cast aluminium-alloy shell with a double damping, multi-stage silencing system, which is why it runs quiet and feels heavy for its size. The air is non-oil-lubricated, so it stays clean all the way to the stone. Three sizes: V10 at 10 L/min, V20 at 20 L/min and V30 at 30 L/min. Unlike most pumps in this class the manifold, tubing and brass connector are included - a 4-way on the V10 and V20, a 6-way on the V30 - so it is plug-and-play for a multi-bucket DWC or a big reservoir.
Key Benefits
- Manifold included - 4-way (V10, V20) or 6-way (V30), plus tubing and a barbed brass connector
- Diaphragm compressor, non-oil-lubricated - clean air, no lubricant in the nutrient
- Cast alloy shell with multi-stage silencing - the quiet end of the range at 35-40 dB
- Removable filter cover so the pump can draw clean air from outside a dusty or CO2-enriched tent
- Fully weatherproof - indoor or outdoor
- Low running cost - 10W, 15W and 25W
Low dissolved oxygen in warm, still nutrient
Roots in a reservoir or DWC bucket depend on the air you push in: warm water holds less dissolved oxygen, and a pump sized for a fish tank leaves the bottom of a 20-litre bucket flat. Pick the V by stone count and water volume, and go up a size if the room runs warm.
How to Use
- Site the pump above the water line or fit non-return valves on each line.
- Connect the 8mm outlet to the supplied manifold and run standard 4mm airline from each tail to a stone.
- Sizing guide: V10 about 2-4 stones or up to roughly 100L; V20 about 4-8 stones or 200L; V30 about 6-10 stones or 300L.
- Keep the filter cover clean; it lifts off without tools.

Questions & answers
What comes in the box?
The pump plus a manifold, tubing and a barbed brass connector: a 4-way manifold with the V10 and V20, and a 6-way with the V30.
Which size suits my system?
As a guide, the V10 runs about 2–4 stones or up to roughly 100 litres, the V20 about 4–8 stones or 200 litres, and the V30 about 6–10 stones or 300 litres. Go up a size if the room runs warm.
Should I choose the V30 or the Hailea Professional?
Both reach 30 L/min. The V30 has a cast alloy shell and comes with a 6-way manifold; the Professional has a six-outlet 30 L/min model and a ten-outlet 60 L/min model if you need more air.
How quiet is it?
Around 35–40 dB, helped by the cast aluminium-alloy shell and double damping, multi-stage silencing.
Can it go outdoors?
Yes, it's fully weatherproof. The removable filter cover also lets it draw clean air from outside a dusty or CO2-enriched tent.
