Pond Pro® CA-65 High Flow Air Compressor - 1/4 HP
The Pond Pro® CA-65 High Flow Air Compressor is a North American-made, oil-less rocking piston compressor designed for pond, lake, and dugout aeration systems. This compact 1/4 HP compressor suits aeration applications in water about 5–30 ft deep.
The CA-65 delivers 5.50 CFM open flow and maintains 3.10 CFM at 15 PSI. It can support several small diffusers or up to two large diffusers, depending on operating depth, diffuser requirements, airline length and overall system design.
Part of the Pond Pro® Can-Air® series, the CA-65 is designed for continuous or intermittent operation and combines strong airflow under pressure with readily available replacement parts and rebuild components.
Compressor Only – Replacement or Warranty Use
This compressor is offered as a replacement component for Can-Air® Aeration Systems. It is intended for warranty replacement, service, repair, or maintenance of an existing Can-Air® aeration system.
Protect Your Compressor: Keep the compressor protected from the elements and properly ventilated and cooled. For outdoor installations, consider the Pond Pro Post-Mount Compressor Cabinet with cooling fan, sold separately.
