Item #: RA1-NC
OUR PRICE: $998.00

Introducing the Kasco Robust Aire complete pond aerator kits. If you own a deep pond (8 to 50 feet deep) then our Kasco Robust Aire Pond aeration system is your best option. This aeration system is ideal to eliminate foul odors and reduce the presence of excess nutrients. It also improves and expand the oxygenated habitat for the fish and oxidize organic bottom muck that often accumulates at the bottom of deep ponds.

Product Description:
  • 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.
This system includes:
  • 1 Teich-aire KM-60 1/4 HP piston compressor
  • One, 100-foot roll of 3/8 inch Sure Sink weighted tubing
  • Robust Aire diffuser assembly
  • Post Mounted Cabinet (optional)
The Kasco RA1 Pond Aerator System is available with three options for enclosures:
 Large Base Mount Cabinet
• Dimensions are 24” x 18” x 20”H
• 120 volt receptacle or a 240 volt junction box
• 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.
Post Mounted Cabinet is mountable on an exterior wall or wooden post.
• Dimensions 19” x 12” x 12”H.
• 120 volt receptacle or a 240 volt junction box.
• 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.
No Cabinet:
This is desired when installing the compressor system in your own structure. Compressors need to be kept out of the weather in a well-ventilated area. A galvanized mounting bracket system is included with each compressor to allow mounting to a floor, wall, or pedestal. Rubber mounting feet and all hardware are included as well. Remote manifold is easily mounted via wood screws.
Sure Sink Weighted Tubing 
Available in easy to handle 100 foot coils. RA systems 1-3 include 100 feet of 3/8 tubing for each diffuser. Each coil is boxed and includes our full packet of barbed connectors and adapter fittings, and all-stainless steel tubing clamps. You will be prepared to make any connection necessary with the tubing kit. Additional 3/8 or 5/8 Sure Sink weighted tubing is available when additional length is needed.

Advantages of Using a Robust-Aire System

  • No electricity in the water. This can be especially important where swimming is allowed.

  • No floating equipment at the surface. Boating is not hindered and the natural view of the lake can be enjoyed.
  • No electricity needed at the edge of the pond or lake. Robust-Aire can be remotely installed away from the water’s edge. Air can be delivered to the water’s edge instead of electricity. This can result in an installation cost savings. This option may be preferred where it is more convenient to have the compressor system consolidated with other equipment.
  • Robust-Aire is more effective at aerating deeper waters than a floating fountain or high-volume surface aerator. Robust-Aire becomes effective at 8 feet of depth and increases efficiency with respect to water flow at the water deepens. Water is pumped directly from the bottom, all the way to the top. Robust-Aire compressors can inject air 50 feet deep!
  • Robust-Aire is cost effective to purchase and operate for larger surface areas. These systems can effectively destratify and aerate deep lakes with much lower equipment costs and energy consumption. Robust-Aire systems are the most efficient on the market.
  • Low maintenance. Most maintenance and inspection may be conducted onshore. Rocking piston compressors do not require internal maintenance as often as other compressors.

Excellent product! Very easy install!

This aerator came in a few days and is very nice quality. Installation was a breeze. Working great and definately got my pond moving water off the bottom.


Kasco Robust Aeration System Works Great

Bought this system for my 1/3 acre pond. Previously had used my windmill but was becoming expensive and time consuming to maintain. System came in excellent packaging and easy to follow instructions. Placed in my pond within an hour and has been working great. Seems to be turning over much more water than my windmill system did. Purchased optional case with fan that hangs on a post by my pond. Most work involved was to run electric out to the post. Great purchase - very happy.
