Description

RobustAire™ systems pump compressed air from a shore-mounted compressor through self-weighted lines to a diffuser on the pond, lake, or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen transfer as well as beneficial water movement and mixing.

Inclusions

RobustAire™ Diffusers

The diffusers are designed to produce fine air bubbles with minimum pressure. The base is made of durable plastic and comes with a seal that allows you to fill the base with gravel or other ballast substrate. The design keeps the diffusers at an optimal level above the pond bottom. The fittings are durable and bolted to ensure that the ballasted pipe does not come loose during installation or while maintaining the diffusers. A check valve with Viton seals prevents water from entering the pipe when the system is not in operation.

Self-Sinking Airline

Available in easy-to-handle rolls of 100 feet. Rolls are delivered in a box and come with our complete set of connectors, fittings and all necessary stainless steel collars. Additional lengths of ballasted hose ⅜″or ⅝″ are available when required (special order of SureSink™ Weighted Air Line Tubing).
