12-Way Steel Air Manifold

12-Way Steel Air Manifold — Mid-Scale Airstone Splitter

A 12-way stainless steel manifold — the mid-scale option between the 8-way and 18-way. Each of the 12 outlets has its own hand-operated on/off tap for individual airflow control. Stainless steel construction eliminates rust for reliable long service in humid grow-room conditions. Right-sized for mid-size DWC setups or multi-bucket aeration.

Why growers choose the 12-way manifold:

• 12 individually-controlled outlets — mid-scale splitting for 6-12 DWC buckets or aeration zones
• Individual tap per outlet — balance airflow, shut off unused lines
• Stainless steel construction — rust-resistant, durable in humid environments
• Long service life — high-grade steel outlasts cheap alternatives
• Simultaneous applications — run multiple DWC systems or aeration zones from one pump
• Fits standard 6mm airline — universal compatibility
• Mid-scale right-sizing — better value than 18-way if you only need 12

Who it's not for:

For smaller setups (2-4 airstones), a 4-way manifold is cheaper and adequate. For larger commercial systems (15+ airstones), step up to the 18-way or multiple 12-ways. Check your air pump's total output can supply 12 airstones — undersized pumps leave downstream outlets starved of air.
