Aquarium Air Manifolds

Aquarium Air Manifolds

Find an air manifold to use with your aquarium air pump at Finest Filters. Our aquarium air manifold products are designed to direct air from your pump to air stones or bubble disks in your fish tank, while allowing you to vent off back pressure if you aren’t using all of your pump’s outlets. An air flow manifold can be a versatile investment, and you’ll find a great choice available in our collection. 

The Ista Metal Air Splitter Valve Manifold is a good option, as it comes with 2, 3, 4, or 5 individually controllable outputs, depending on your specific requirements. This particular aquarium air manifold is compatible with standard 4mm (internal diameter)/6mm (external diameter) air line. It also comes with an acrylic mounting plate so it can be fitted to the top of your aquarium or inside the aquarium cabinet easily.

We also stock 4 way, 8 way, 10 way, and 12 way air line splitter air manifolds to use with either your fish tank or pond pump, as well as a range of accessories to help you adjust the air flow in your home aquarium. These include the Ista Twin Air Flow Control Valve and Straight Airline Connectors, which are available in packs of 5 or 10. 


Try using an air manifold and see if it makes a difference to the air flow in your fish tank or home aquarium. When you purchase an aquarium air manifold from Finest Filters, you can be sure you’re getting a high quality product.
