Depending on your Robinair machine generation, the filter serial number location varies. Follow this step-by-step guide:

Where to Buy & "Fake" Filters

When searching for these filters online, be aware of the following: robinair filter serial number

OEM vs. Aftermarket: There are aftermarket filters (usually cheaper) that fit Robinair machines.
- Review: Many HVAC techs report that high-quality aftermarket "lookalike" oil filters work fine, but for the Filter Drier (Moisture Indicator), it is highly recommended to stick with Genuine Robinair (OEM) parts. The sight glass accuracy on cheaper clones is often unreliable.
Amazon/eBay Caution: Listings often say "Fits Robinair" in the title. Do not rely on the title. Scroll down to the compatibility list. If your specific model number isn't listed, do not buy it.

How to Use Your Machine’s Serial Number to Find the Right Filter

Locate your machine’s data plate. This is a metal or heavy plastic sticker. It lists:
- Model Number (e.g., 34788)
- Serial Number (e.g., 34788-2105-12345)
- Voltage and Amperage
Go to the official Robinair parts lookup tool (my.robinair.com or the official Robinair website). Report: Understanding Robinair Filter Serial Numbers Part 5:

Refine by your machine’s serial number range. The parts catalog will say: “For serial numbers below 34788-9000, use part 12055. For serial numbers 34788-9000 and above, use part 12716.” USA: 1-800-822-5561 (Press 2 for Tech Support) Hours:

B. Factory Shift and Batch

In rare cases, a specific batch of filters might have a defect (e.g., leaking seals, insufficient desiccant). Robinair can issue a recall or technical service bulletin (TSB) referencing a range of serial numbers. If your filter’s serial number falls within RAI-2201-0001 through RAI-2201-5000, you may be eligible for a free replacement.

Q2: Does the filter serial number affect my machine’s warranty?

A: Yes. If you file a warranty claim for a failed compressor or stuck valve, Robinair may request the serial number of the last filter installed. If you cannot provide it, or if the serial number indicates an expired or counterfeit filter, your claim will be denied.

4. Locating the Equipment Serial Number

Robinair machines (34700, 34900, 35100 series): Serial number is on a silver or white label on rear panel or underside of unit.
Older units: May have serial number stamped into chassis or on compliance label.
