4-Way Steel Air Manifold — Small-Scale Airstone Splitter

4-Way Steel Air Manifold — Small-Scale Airstone Splitter

The entry-size air manifold — 4 stainless steel outlets with individual hand-operated on/off taps. Ideal for small DWC setups, dual-bucket systems, or any application where 4 airstones from one pump is enough. Stainless steel eliminates rust; simultaneous applications let you run several processes from a single air pump.

Why growers choose the 4-way manifold:

• 4 individually-controlled outlets — perfect for 2-4 airstones or small aeration zones
• Individual tap per outlet — balance airflow, shut off unused outlets
• High-grade stainless steel — eliminates rust, ensures long service life
• Simultaneous applications — run 4 independent air-delivery processes from one pump
• Robust construction — simple, durable, nothing to fail
• Fits standard 6mm airline — universal air-system compatibility
• Best value for small setups — no point buying 8-way if you only need 4

Who it's not for:

For 6+ airstones, step up to a 6-way, 8-way, or larger manifold. For single-airstone setups, a direct connection from the air pump is simpler. Check your air pump can supply 4 airstones adequately — undersized pumps leave outlets starved of air.
