RA5-NC, Robust-Aire (No Cabinet)

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.

1 Teich-aire KM-60 1/4 HP piston compressor

1 Teich-aire KM-120 1/2 HP piston compressor

Cooling fan and mounting kit
