A part number is the safest starting point for an Atlas Copco spare-parts enquiry. A commonly encountered format is the 10-digit identifier, such as 1622507381, sometimes printed with spaces. It narrows the request to a specific item, but it should be checked together with the machine and the physical label before anyone promises fitment.
What the part number does — and does not do
“Air filter for GA55” can mean several different parts. The number is much more precise. It gives the buyer and supplier a common reference and reduces the chance of quoting a visually similar component. It does not automatically confirm authenticity or fitment for every serial range. If you already have a number, you can search any part number to get a genuine-parts quote.
Where to find the number
Check the component label, the original box, the compressor parts list and a previous invoice. Transcribe every digit; do not rely on a filename or a handwritten note. When the label shows grouped digits such as 1622 5073 81, remove the spaces only when entering it into a search field. Keep a photo of the original layout.
Build a small evidence pack before requesting a quote
For filters and standard consumables, the number may be enough for a preliminary quote. For controllers, valves, motors and airends, send the compressor model, complete serial plate, old-part label, connector side and mounting arrangement. This is faster than resolving a mismatch after the part has crossed a border.
Five checks for authenticity and traceability
- Match the exact number on the part, the box, and your quote — all three should agree.
- Check the packaging — genuine parts come in Atlas Copco branded packaging with clean printing and a part label.
- Look at build quality— correct materials, clean seams, proper markings. Copies often feel and look “almost right”.
- Ask about the source — use an identifiable supplier that can document the item and its commercial origin.
- Be wary of prices that are too good — a price far below the market usually means a non-genuine part.
Atlas Copco has also introduced package-label QR verification for selected genuine parts. Where it is present, scan the code and follow the official verification flow. A missing QR code is not a universal counterfeit test, because implementation varies by product and packaging date.
What a superseded part number means
Manufacturers revise parts. An older number may point to a newer service replacement, but a supplier should confirm the supersession and whether the replacement needs an adapter, cable, software configuration or companion kit. Never turn “the old number is unavailable” into an automatic order for the nearest-looking alternative.
What a usable quote request contains
- Exact part number and required quantity.
- Compressor model and serial number or serial range.
- Destination country and requested shipping method or Incoterm.
- Clear label photos and the deadline for the planned maintenance stop.
For a practical comparison, ask every supplier to quote the same scope: current part number, condition, quantity, lead time, origin, warranty terms and shipping basis. That makes a low price easier to evaluate without losing the technical details that determine whether the part is usable.
Why genuine parts are worth evaluating on total cost
A genuine part is engineered to the same tolerances, materials and service life as the component your machine was built with. A non-genuine filter or separator that looks similar can flow differently, break down sooner, or shed material into the oil — and a small saving on a separator can cost you an airend. Genuine performance or contaminate the oil circuit. Confirm warranty and air-quality requirements for the specific compressor and application rather than assuming a universal policy.
