- Replacement compressor for Kasco Robust-Aire and Home Series systems
- Upgrade for non-Kasco diffused aeration systems
Airflow by Model (CFM)
Airflow drops as back pressure rises (deeper diffusers mean more pressure). Kasco's published figures:
1/4 HP (KM-60C / KM-60HC): 3.8 CFM at 0 PSI, 2.9 CFM at 20 PSI, 2.2 CFM at 50 PSI.
1/2 HP (KM-120C / KM-120HC): 5.5 CFM at 0 PSI, 4.2 CFM at 20 PSI, 2.7 CFM at 50 PSI.
3/4 HP (KM-200C / KM-200HC): 7.4 CFM at 0 PSI, 6.4 CFM at 20 PSI, 5.0 CFM at 50 PSI.

FAQs
Teich-Aire Rocking Piston Compressors FAQs
Answers to common questions about the Teich-Aire Rocking Piston Compressors.
What is the difference between the 120 V and 230 V options?
Both are the same compressor wound for different supply voltages. Kasco rates them 115 V (60 Hz) and 208-240 V (50/60 Hz); the higher-voltage models draw roughly half the amps.
Does the compressor need oil?
No. Teich-Aire compressors are an oil-less rocking piston design.
Can I use a Teich-Aire in a non-Kasco aeration system?
Yes. Kasco says Teich-Aire compressors can replace old or damaged compressors and upgrade non-Kasco diffused aeration systems.
Which size do I need?
It depends on how many diffusers you run and how deep they sit. More depth means more back pressure and less airflow. Call the Weeders Digest team at 877-224-4899 and we will help you size it.
Is it designed to run all the time?
Yes. Kasco designs Teich-Aire compressors for continuous, year-round aeration.
Does it have overload protection?
Yes, each compressor has thermal overload protection and a ramped valve plate that lets it restart under load.
