3/4 HP - Kasco Teich-Aire Rocking Piston Compressor

3/4 HP Kasco Teich-Aire rocking piston pond aeration compressor is designed for demanding pond aeration and other deep-water applications where reliable, oil-free air delivery matters. Built around a rugged rocking piston design, this compressor is a strong fit for customers who want consistent performance with minimal routine upkeep and the flexibility to run either continuously or intermittently, depending on seasonal needs and dissolved oxygen goals.

Because it is oil-less, it helps keep the air stream clean—an advantage for aeration systems where maintenance simplicity and long-term reliability are priorities. The unit also includes thermal overload protection to help safeguard the motor, along with a ramped internal valve plate designed to support restart under load after a power interruption. A 6 ft. power cord is included for straightforward setup in common installations.
