Description

Kasco Robust-Aire Systems are available as complete packages from one to six diffuser heads.  These highly efficient and effective diffused aeration systems are designed and sized to meet most typical aeration applications and come complete with everything you need including all connectors and adapter fittings.  Installation is quick and easy with Kasco’s exclusive SureSink weighted air lines by simply sinking in place without separate weighting or anchoring.

All Robust-Aire diffused aeration systems are available with an optional remote manifold allowing you to install the compressor up to a mile away from the water’s edge. The remote manifold also allows you to adjust airflow to each individual diffuser head to get the balance of airflow and performance you need. Simply run PVC pipe from the compressor to the remote manifold located near the pond or lake edge.
