Remote Manifold (RM Option)
Robust-Aire™ systems are available with an optional remote manifold which allows you to install the compressor up to a mile away from the water's edge! The remote manifold 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 edge of the lake or pond.

Oversize Compressor Choices (DP and XL Options)
The Robust-Aire™ systems all come with Teich-Aire compressors, but for heavier duty applications, two larger sizes are available: DP and XL.
