  8. Pentair Aquatic Eco-Systems Point Four Pressurized Column

    Pentair Aquatic Eco-Systems Point Four Pressurized Column

    $0.00

    High-performance gas injection system—flexible with low operating costs

    The Point Four Pressurized Column has applications in aquaculture, horticulture, wastewater and effluent treatment, and mining. In a typical system, pressurized water is side-streamed to the column, where it is supersaturated with dissolved gas and then re-integrated to the mainstream.

    The system can be controlled manually, semi-automatically, or automatically. An automatic system consists of a level or oxygen controller, water flow meters, pressure gauge, and control valves.

    Features and Benefits

    100% gas utilization

    • No gas losses from the system. 100% of the oxygen is dissolved into the water with no bubbles.

    High absorption capacity

    • Packs the most gas into a given volume of water; e.g., 200 mg/L of dissolved oxygen at 60 psi and 15ºC.

    Custom engineered system

    • Each system is designed to meet your specific needs.

    Low operating costs

    • Only a small side-stream is required (typically 5% of the main flow) to achieve desired D.O. levels. If the system has adequate line pressure, integrating the column into the main flow requires no additional pumping.

    Optional automatic control

    • Simply enter the desired oxygen level into the controller. Oxygen concentration, and column water level are continuously monitored and controlled.

    Flexibility

    • The system is designed to accommodate varying water flows.

    Retrofit

    • The system is easily installed into any pre-existing facility with minimal disruption or down time.

  9. Sweetwater® Piston Compressor, 50 psi max pressure, 3/4 hp, 115/230V, 60 Hz, 9.7 amps @ 20 psi, 4.7 cfm @ 10 psi

    Sweetwater® Piston Compressor, 50 psi max pressure, 3/4 hp, 115/230V, 60 Hz, 9.7 amps @ 20 psi, 4.7 cfm @ 10 psi

    $852.59

    These oilless piston-type, motor mounted air compressors are for those applications requiring higher pressures than are available from our vane type compressors. These 50-psi models deliver much more air than the 100-psi models normally found in the marketplace.

    Whether you're aerating a deep water lake, overcoming the friction loss of a long run of air piping, forcing air through a fine pore diffuser or filling up car tires, these compressors will provide a continuous supply of oil-free air. Price includes an 8' power cord (230V only), air filters, thermal overload protection and 50-psi pressure relief valve. Due to amp draw, 115V models do not have power cords.

    One-year warranty. Made in USA.
