Kasco RA1-NC, Robust-Aire (No Cabinet)
Robust-Aire Owner's Manual
Robust-Aire Spec Sheet
The Kasco Robust-Aire pond aerator diffusers are the most efficient on the market and create 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 thick HDPE plastic and a locking fill plug allows you to fill it with pea 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 ensures 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.
