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.
A: Even if your machine is rarely used, change the filter every 12 months. The desiccant inside has a shelf life. Look at the filter’s manufacture date from its serial number. If the filter was made 18 months ago, it is already degraded – do not install it.
When it is time to change the filter, follow this safety checklist. The serial number plays a role at multiple steps. robinair filter serial number
Beyond inventory logistics, the serial number is the key to the regulatory kingdom.
1. Warranty Validation Robinair offers a standard warranty (typically one year) on parts and labor. The warranty clock starts ticking based on the manufacture date encoded in the serial number, or the date of purchase if a receipt is provided. If a machine fails and the serial number plate is missing or unreadable, the manufacturer may default to the earliest possible manufacturing date, potentially shortening the customer’s warranty window. A: Yes
2. The "Filter Change" Algorithm Modern Robinair machines, particularly the AC Pro series, track filter saturation internally. They calculate when a filter needs changing based on how much oil and refrigerant has passed through the system. However, when replacing the filter, the machine often prompts the user to reset the filter timer. This does not require inputting a serial number, but it relies on the premise that the new filter is fresh. If a technician installs an old filter found on a shelf—identified by an old date code/serial on the canister—the machine’s algorithm will be out of sync with reality, leading to potential contamination of the refrigerant tank.
3. EPA Compliance Under Section 608 of the Clean Air Act, technicians must maintain records. While the regulation focuses on the amount of refrigerant recovered, the equipment used is part of the record. When an EPA auditor checks a shop's compliance, they match the service logs to the specific machine serial numbers. A shop claiming to use a new high-end Robinair unit while actually using an older, non-compliant unit is a red flag that triggers deeper investigations. A: Even if your machine is rarely used,
This is the most common user question: "I have my machine’s serial number. Which filter do I buy?"
Critical rule: The machine’s serial number determines the filter part number, not the old filter’s serial number.
Robinair has changed filter designs over the years. For example:
The most common source of confusion with Robinair filters is terminology.
