One Family, Three Displacements: Find Your Bitzer 4-Cylinder Match
Bitzer's F400 bus compressor family is the workhorse of coach and transit cooling around the world. Three 4-cylinder members cover the mid-range cooling band, and choosing correctly starts with matching displacement to vehicle length:
Model |
Bitzer 4PFCY |
Cylinder volume |
558 cm³ |
Displacement (1450 rpm) |
48.5 m³/h (1712 CFH) |
Displacement (3000 rpm) |

Family siblings |
4NFCY 647 cm³ | 4GFCY 744 cm³ |
Typical application |
7–9 m coaches, minibuses & mid-size trucks |
If your fleet already runs 4NFCY or 4GFCY units, the 4PFCY fills the compact end of the range – ideal where the AC duty is moderate but the space under the floor or on the roof is tight.

Bitzer 4PFCY – Frequently Asked Questions
Q: What is the difference between 4PFCY and 4NFCY? A: Both are 4-cylinder F400 compressors; the 4PFCY displaces 558 cm³ versus 647 cm³ for the 4NFCY, so it suits smaller cooling loads while the 4NFCY covers larger coaches.
Q: Is this an original Bitzer compressor? A: We supply both original and professionally remanufactured 4PFCY units – state your preference when ordering.
Q: Which clutch voltage can I get? A: Both 12V and 24V DC magnetic clutch versions are available.
Q: What is the delivery time? A: Standard models ship within 3–7 business days worldwide.
Q: Can you confirm fitment? A: Send your bus model, AC unit brand and OEM part number – our engineers will verify before you order.
