How Much Air Does the CA-125 Produce?
The CA-125 produces 6.80 CFM at 0 PSI, 5.80 CFM at 5 PSI, 5.70 CFM at 7.5 PSI, 5.55 CFM at 10 PSI, and 5.20 CFM at 15 PSI.
How Deep Can the CA-125 Operate?
The CA-125 is suitable for pond, lake, and dugout aeration applications approximately 5–35 ft deep. Actual requirements depend on diffuser type, airline length, elevation, pressure loss, and system configuration.
Can the CA-125 Run Continuously?
Yes. The CA-125 is suitable for continuous or intermittent duty.
Can the CA-125 Run on 120V or 240V?
Yes. The CA-125 has a dual-voltage motor for 120V or 240V, 60 Hz operation.
How Many Diffusers Can the CA-125 Operate?
The CA-125 can support up to two large diffusers. Actual capacity depends on diffuser airflow requirements, operating depth, airline length, and system pressure.
Does the CA-125 Require Oil?
No. The CA-125 uses an oil-less rocking piston design.
How Often Should the CA-125 Be Rebuilt?
Rebuilds are required every 18–24 months of use. CA-Series rebuild kits are available here.
