The verified records for Bosch cover the Air Flux 4300 / 5300 / 5300A / 6300A families. They are intended to build a purchasing shortlist; they do not prove that codes from two markets are direct equivalents.
Bosch VRF model codes can change with country, electrical supply, refrigerant, product generation and local certification. The table below brings together examples verified in publicly available manufacturer documents.
Important: A matching capacity number or similar series name does not mean that voltage, frequency, refrigerant, board software, connection ratio or certification is identical.
Bosch model-code comparison by country and region
| Country / market | Product group | Verified example codes | How to interpret it | Source |
|---|---|---|---|---|
| Türkiye | Series / product family | Air Flux 5300AF5300 | Code or family verified in a local product/project document. | [1] |
| Poland / Europe | Series / product family | AF4300AAF5300A(C)AF6300A C | Generation and regional naming used in the European document. | [2] |
| East Africa | Outdoor unit | AF5300A 25-3AF5300A 28-3AF5300A 33-3AF5300A 90-3 | Numbers indicate capacity classes; the range is not one single unit code. | [3] |
How should a VRF model code be read?
Letters at the beginning usually identify the family and indoor/outdoor unit type, the middle number often indicates capacity class, and ending letters can describe generation, power supply, regional package or factory variant. The exact logic changes by brand and series.
The indoor-unit code matters as much as the outdoor-unit code. Cassette, ducted, wall and ceiling units use different prefixes; the approved combination table must be checked even when controls and communication protocols look similar.
Checklist before quotation and ordering
- Destination country and installation city
- Supply voltage, phase and frequency
- Refrigerant and local environmental rules
- Complete outdoor and indoor unit model codes
- Nominal capacity, operating range and connection ratio
- Catalogue revision, technical data and certification
- Controller, central control and BMS gateway compatibility
- Spare-parts and service coverage in the destination market
When searching for a Bosch code
Use the complete code together with the country and terms such as “technical data”, “submittal”, “catalogue” or “service manual”. Ask for the full equipment-label code in the quotation instead of an abbreviated family name.

Share the destination, capacity, voltage and application so the current product family and exact model code can be rechecked at quotation stage.
