Robust Aire Diffuser Assembly [772100]

Price: $199.50 

Robust-Aire diffusers are the most efficient on the market and create more water flow to aerate your pond. Diffusers are designed to provide a fine air bubble with the least amount of pressure.

The base is made of durable plastic and a locking fill plug allows you to fill it with gravel or other weighted substrate. It has a raised design that keeps the diffusers performing at an optimal level above the pond bottom.

A durable, bolted,strain relief attachment insures that the weighted tubing will not become detached during installation or maintenance. A check valve with Viton seals keeps water from entering the tubing when the system is not operating.

Can be used on existing pond aeration systems as well.
