A quiet, energy-efficient four-outlet aeration kit for water gardens and koi ponds up to 3,500 gallons — built for year-round summer aeration and winter de-icing.
Adequate oxygen levels and circulation are critical for pond and fish care. The CAS4 kit provides quiet, energy-efficient aeration with four independent outlets, letting you place diffusers in four different spots for the best coverage in ponds and water gardens up to 3,500 gallons.
Like the rest of the Compact Aeration Series, it's a continuous duty system built for both summertime aeration and wintertime de-icing. The 115V compressor draws only 8.2 watts and operates in water up to 4' deep. If used outdoors, the compressor needs a proper enclosure.
Runs quietly enough for water gardens and ponds near seating areas.
Run four diffusers in different spots for the widest circulation coverage in the Compact Series.
Continuous duty design handles both summer aeration and winter de-icing.
Compressor is backed by a 2-year warranty for reliable long-term use.
