Description
The Robust-Aire RA2 system includes a rocking piston compressor, 200 feet of 3/8 inch Sure Sink weighted tubing, and two (2) Robust Aire diffuser assembly.
Robust-Aire Diffusers
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.
Enclosures: Each of the systems is available with three options for enclosures:
Option #1 – No Cabinet (NC): This is desired when you want to install the compressor system in your own structure. Compressors need to be kept out of the weather in a ventilated area. Remote manifold is easily mounted via wood screws.
Option #2 – Post mounted cabinet (PM) is mountable on an exterior wall or wooden post.

A single cooling fan provides 110 CFM ventilation.
Compressor is mounted at the factory in the cabinet which is provided with acoustical foam and a keyed cabinet lock.
