RESUN
RESUN Air Pumps
RESUN's air pumps are built around multi-outlet aeration, the 6-outlet pump delivers 1320 L/HR split across six independent outlets, and the 12-outlet steps up to 3000 L/HR. Both suit larger DWC setups or multiple buckets running off one central pump rather than wiring up a separate pump per bucket.
Splitting output across more outlets does reduce flow at each individual outlet compared to a single-outlet pump running the same total output, so for a single bucket or small reservoir, a dedicated single-outlet pump like those in the Aqua One range is often the more efficient choice. The multi-outlet RESUN pumps earn their place once you're running several buckets that need to stay synchronised off one air supply.
Frequently Asked Questions
Should I get the 6-outlet or 12-outlet RESUN pump?
Count your air stones, then choose the pump with enough outlets to run all of them without splitting tubing further than the pump's rated capacity supports. More buckets generally means the 12-outlet is the better fit.
Is a multi-outlet pump better than several single pumps?
For several buckets, yes, it's one unit to maintain instead of several, and outputs stay balanced across all outlets. For a single bucket, a dedicated single-outlet pump is usually more efficient.
