Planned maintenance is the cheapest thing you can do for a GA screw compressor. A genuine service kitbundles the consumables your machine needs at each service into one part number — so nothing gets missed. Here’s what’s in a kit, when to change it, and how to pick the right one for your GA model.
Atlas Copco GA service intervals
Most GA compressors follow a step of scheduled services (your machine’s controller and manual give the exact hours for your unit):
- Minor / A-service — around every 2,000 running hours or once a year: air filter, oil filter, and oil check.
- Major / B-service — around every 4,000–8,000 hours: the above plus the oil separator and a full oil change, valves and o-rings inspected.
Running hours matter more than the calendar. A dusty site or long hours will pull these intervals in.
What’s inside a GA service kit
- Air filter element — protects the compression element from intake dust.
- Oil filter — keeps the circulating oil clean.
- Oil separator — removes oil from the compressed air (on major-service kits).
- Genuine oil — PAROIL, matched to your machine.
- O-rings and seals — so everything reseals correctly.
Choosing the right kit for your model
Kits are model- and service-specific — a kit for a GA30-45 is not the same as a GA55 or GA75 kit, and a 4,000-hour kit differs from an 8,000-hour one. The safest way to order is by the kit’s 10-digit part number; if you don’t have it, send us your exact GA model and serial number and we’ll match the correct genuine kit.
Genuine kits vs loose or copy parts
A genuine kit guarantees the parts are matched to each other and to your machine, in one order, at the right service life. Piecing a service together from copy filters is where compressors quietly lose efficiency and airends fail early.
