8-Way Steel Air Manifold

8-Way Steel Air Manifold — Tap-Controlled Airstone Splitter

A sturdy 8-way steel manifold for splitting air pump output across multiple airstones — reduces airflow per outlet to match airstone requirements, and includes individual taps on each outlet so you can alter flow or shut off unused lines completely. Essential for running multiple DWC reservoirs or aerating multiple zones from a single air pump.

Why growers choose the 8-way steel manifold:

• 8 individually-controlled outlets — split one air pump across 8 airstones or zones
• Individual tap on each outlet — balance airflow per line, shut off unused outlets
• Steel construction — rust-resistant, proper durability in humid grow-room conditions
• Reduces airflow to airstone-suitable levels — prevents overflow or airstone damage from over-pressure
• Essential for multi-DWC setups — one air pump serving multiple bubblers cleanly
• Compatible with standard 6mm airline — fits industry-standard aquarium/hydro air tubing

Who it's not for:

For smaller setups (2-4 airstones), a 4-way manifold is cheaper and adequate. For very large commercial systems (12+ airstones), multiple 8-ways or a dedicated commercial manifold works better. Check your air pump's total output can supply 8 airstones adequately — undersized pumps will leave downstream airstones starved.
