20 way plastic airline manifold for distributing one larger air supply across multiple air stones, air curtains and aeration points.

This 20 Way Plastic Airline Manifold provides a straightforward way to divide the output from a larger air pump or compressor across multiple airline runs. With 20 separate outlets available, it is particularly useful for larger hydroponic systems where numerous reservoirs, pots or air stones require aeration.

Bringing multiple airline feeds together at one central manifold helps keep larger aeration systems organised and avoids the need for a separate pump outlet for every air stone.

The manifold can be used with compatible 4mm airline to supply air stones and air curtains throughout a growing system. It can also be used to distribute nutrient solution in suitable NFT installations.

Why use a 20 Way Airline Manifold?

  • 20 separate outlets – distribute one main supply across up to 20 individual lines.
  • Designed for 4mm outlet line – connect individual airline runs for air stones, air curtains and other compatible aeration equipment.
  • Ideal for larger aeration systems – particularly useful when one air pump or compressor needs to serve numerous growing positions.
  • Centralised distribution – keeps multiple airline branches together for a cleaner, more organised installation.
  • Suitable for hydroponics – useful for aerating nutrient reservoirs, DWC systems and other hydroponic setups.
  • Air or nutrient distribution – can also be incorporated into suitable NFT systems for distributing nutrient solution.

What is a 20 way airline manifold used for?

A 20 way manifold is designed for larger systems where a single high-output air pump or compressor needs to supply numerous aeration points. The incoming supply enters the manifold and is divided between 20 individual outlets.

Individual airline runs can then be routed to air stones, air curtains or other compatible aeration equipment positioned throughout the growing system.

This makes the manifold particularly useful for multi-pot hydroponic installations, larger nutrient reservoirs and systems containing several separate tanks or growing modules.

How to use the 20 Way Plastic Airline Manifold

Connect the manifold inlet to a suitable main supply from your air pump or compressor. Attach compatible 4mm airline to the required outlets and route each line to its air stone, air curtain or other aeration device.

When running a large number of outlets, the connected air pump needs sufficient output to supply the complete system. Air delivery at each point will depend on pump performance, the number of outlets being used, airline length and the resistance created by the connected air stones or diffusers.

Keep airline routes as tidy and direct as practical, avoiding unnecessary kinks or restrictions that could reduce airflow.

20 Way Plastic Airline Manifold FAQs

What does a 20 way airline manifold do?

It divides one larger air supply between up to 20 individual airline runs, allowing multiple air stones or other aeration devices to operate from a suitable air pump or compressor.

How many air stones can I connect to the manifold?

The manifold provides 20 outlets, allowing up to 20 individual airline runs. The number of air stones that can operate effectively will depend on the output of the connected air pump and the requirements of the aeration equipment.

What size airline fits the outlets?

The manifold uses 4mm outlets for connecting compatible airline to air stones, air curtains and other aeration accessories.

Can I use this manifold with a hydroponic air pump?

Yes. It is designed to split the supply from a suitable larger air pump or compressor across multiple airline feeds.

Can the manifold be used with air stones and air curtains?

Yes. It can distribute air through individual airline runs to compatible air stones, air curtains and similar aeration equipment.

Is a 20 way manifold suitable for DWC?

Yes. It is particularly useful for larger DWC installations where one suitably sized air pump needs to supply multiple buckets, reservoirs or air stones.

Can this manifold distribute nutrient solution?

Yes. This style of plastic manifold can also be used to distribute nutrient solution in suitable NFT systems.

Does the manifold have individual airflow controls?

No. This is a simple plastic distribution manifold rather than a valved manifold, so the individual outlets do not have built-in airflow adjustment controls.

Do I need a larger air pump for a 20 way manifold?

A pump needs sufficient output for the number of outlets and aeration devices being operated. Running 20 air stones will require considerably more air than using only a few outlets, so the pump should be sized for the complete installation.
