Before starting the compressor, ensure the following:
Q: Can I run the Compair Cyclon 111 continuously for 24 hours? A: Yes, but the manual specifies that the duty cycle is 100% only if the ambient temperature stays below 40°C. For continuous running, install a larger air receiver to reduce motor starts.
Q: My manual says "CS Evolution Oil" but I can’t find it. A: Compair CS Evolution (10W-40 semi-synthetic) is still available. Alternatives include Shell Corena S4 R or Mobil Rarus SHC 1025 – but check the manual’s approval list first.
Q: The safety valve opens at 12 bar, but I need 13 bar. A: Do not adjust the safety valve. This is illegal in most jurisdictions. Adjust the pressure switch’s upper limit (if equipped) or check that your dryer’s pressure drop isn’t fooling the sensor. Compair Cyclon 111 Manual
Note: Specifications can vary based on the specific motor voltage, enclosure type (Open or Sound Attenuated), and year of manufacture.
If you have lost your manual, here is the standard startup sequence as prescribed by Compair:
Before Start (Daily):
Start Procedure:
Normal Stop:
Emergency Stop:
If you are currently operating a Compair Cyclon 111 without the manual, stop and locate one before your next service. A common error among maintenance crews is replacing the air/oil separator incorrectly. The manual explicitly diagrams the positioning of the internal gasket and the locating dowel pin. If that pin is misaligned, the separator will collapse, sending sludge directly into the cooler and final discharge line—a repair that often exceeds the value of the compressor.
Occasionally, original paper manuals appear alongside used Cyclon 111 compressors. Ensure the manual’s part number matches your machine’s build year (e.g., 98260-xxx).
Warning: Avoid generic "manual download" sites asking for credit cards without previews. Many host only the parts list, not the full operation and safety guide. Before starting the compressor, ensure the following: Q:
