    The Kasco Marine RA5 Aeration System will work well in ponds up to 9 acres (based on a 15' depth or greater). Less depth will reduce surface aera coverage.

    Effective aeration can be achieved in 4 to 5 acre ponds 5 to 8 feet deep, 6 to 7 acre ponds 8 to 12 feet deep, and 9 acre ponds 12 to 16+ feet deep.

    Please contact us for a free aerial pond mapping to make sure this is the right aeration system for your pond.

    The combination of compressors in the RA5 draw 6.2 amps on a 120v power supply and 2.9 amps on an optional 230v power source (contact us if you require 230v).

    Air output is rated at 8 cfm's at 10 psi.

    Operational depth of the compressors is 50'.

    The Robust-Aire RA5 system includes:
    • One KM-60 model ¼ HP Teich-Aire compressor & one KM-120 model ½ HP Teich-Aire
    compressor. Cabinet is optional (see below).

    • Two valved aluminum manifolds: 1 dual-port, 1 triple-port.

    • Five Robust Aire diffuser assemblies

    The images above are for illustrative purposes only. No airline is included in this package which allows customers to only order what they may need. For any tubing run from the compressor to the diffuser that's under 300' you can use 3/8" airline. For any run greater than 300', please use 5/8" to maintain better airflow to the diffuser.

    ADDITIONAL INFORMATION

    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 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.

    Enclosures:

    The RA5 is available with two options for enclosures - this type of pump does require protection from the elements.

    A large base mount cabinet is suggested as the default method for the system.
    • Dimensions are 24” x 18” x 20”H
    • 120 volt receptacle or a 240 volt junction box.
    • Two cooling fans provide 220 CFM ventilation and are paired with the compressors.
    • Compressor is mounted at the factory in the cabinet which is provided with acoustical foam and a cabinet lock.

    No Cabinet (NC): This is desired when installing the compressor system in your own structure. Compressors need to be kept out of the weather and supplied with active ventilation. 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 is available in easy to handle 100 foot coils.

    RA systems 4-6 do not include airline allowing for the customer to order only what they need or require. To order click on the related products tab above.

    Each coil is boxed and includes our full packet of barbed connectors and adapter fittings, and 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. Non-weighted (5/8)tubing is also available for delivering air over land to the water edge before converting to Sure Sink. All tubing is also available in 500 foot reels. Reels do not include fittings.
