Description
The 2901990826 is the Atlas Copco Preventive Maintenance Pack, the scheduled service set for GA stationary oil-injected compressors in the 18-30 kW class. It is the kit that covers the 8000 running hour service in one order, and it carries the same part number across every record that lists it.
Packs are ordered by part record rather than by contents, because a service set of one programme can look close to another while covering a different interval. The 2901990826 is the current pack for its position, and the number itself is the line the planner carries.
What the 2901990826 Preventive Maintenance Pack Is
The 2901990826 is the preventive maintenance pack built for the GA stationary oil-injected compressor in the 18-30 kW class. The pack bundles the six service kits of the 8000-hour service into one standing order, so the workshop receives the full set instead of sourcing each kit on its own. Item data puts the pack at 60 × 30 × 25 cm and 5.10 kg.
The pack belongs to the service kit family of the Atlas Copco parts programme. Because the 2901990826 is listed under one standing number, the workshop matches it to the record it already holds, and the physical contents are the same whether the pack is read by code or by name. The pack travels as one carton, and the item data is the data sheet the quotation repeats.
Designation and Part Record
The official listing names the part under the number 2901990826, with Preventive Maintenance Pack as the description of the item. The product group code of the item is CKOA, and the material group is S1. Those codes are the internal reference of the parts programme, and they are repeated here only so the workshop can match the 2901990826 to the record it already holds.
The product company of the item is the compressor service division, which is the context the GA service kits also carry. The 2901990826 and its six kits are one package on the spares list, and the number stays valid because it is the current version of the 8000-hour set.

The 8000-Hour Service for GA Compressors
A GA stationary oil-injected compressor reaches its scheduled service at 8000 running hours, and the 2901990826 is the pack that the interval calls for. The service renews the wearing parts that decide air quality and reliability, so the machine returns to its normal duty without a parts gap.
Why the Interval Matters
The 2901990826 is timed to the 8000-hour mark because the filter and separator elements in the pack lose their margin as the hours build. A pack kept current on the list is the pack that fits when the interval arrives, and the service window stays short. The set is built for the GA 18-30 kW class, and the machine record confirms the fitment before the order is placed.
The 8000-hour service protects the compression line and the air path at once. The 2901990826 covers both sides of the service, and the workshop plans the swap knowing every kit is in the carton. A compressor left past the interval works harder than it should, which is why the pack is a planned spare rather than an emergency buy.
What the 2901990826 Pack Contains
The 2901990826 bundles six service kits, each a defined component of the 8000-hour service. The list below is the official bill of the pack, and every kit is present in the carton when the pack arrives.
The Six Kits at a Glance
- KIT FILTER AIR/OIL RXD/FG — 1 piece (air/oil filter kit)
- MIN. PRESS. THERMO. VALVE KIT — 1 piece (minimum pressure thermostatic valve kit)
- KIT OIL SEPERATOR 18-30KW — 1 piece (oil separator kit for the 18-30 kW band)
- KIT CUBICLE FILTERS — 1 piece (cubicle filters kit)
- NON RETURN VALVE KIT — 1 piece (non-return valve kit)
- KIT WEAR DRAIN — 1 piece (wear drain kit)
The 2901990826 lists each kit once, so the service covers the filter, the separator, the valve and the drain in a single pass. The quantity of every item is one, and the pack is the complete 8000-hour set for the GA 18-30 kW compressor.
The Air/Oil Filter and Oil Separator Kits
The first two kits of the 2901990826 guard the air quality of the machine. The KIT FILTER AIR/OIL RXD/FG renews the filter that keeps oil out of the delivered air, and the KIT OIL SEPERATOR 18-30KW renews the separator sized for the 18-30 kW band.
Filter and Separator Duty
The air/oil filter of the 2901990826 is the element the compression line depends on for clean air, and the oil separator is the element that returns oil to the circuit while the air leaves dry. Both are timed to the 8000-hour interval, and the pack carries the correct size for the GA class. The workshop fits the two kits in the same service, and the machine returns to its normal air picture.
The separator kit of the 2901990826 is matched to the 18-30 kW output, so the bore and the media are the ones the compressor was built for. A separator left past its interval lets oil carry into the air path, which is why the pack renews it on schedule rather than by sight.

The Thermostatic and Non-Return Valve Kits
The 2901990826 also renews the valves that shape the oil and air circuit. The MIN. PRESS. THERMO. VALVE KIT holds the minimum pressure and the thermostatic function, and the NON RETURN VALVE KIT keeps the flow in the correct direction.
Valve Renewal in the Pack
The minimum pressure thermostatic valve of the 2901990826 is the part that sets the warm-up and the pressure floor of the oil circuit, and the non-return valve is the part that stops backflow during stop and start. Both sit in the service because their wear shows up as lost efficiency before it shows as a fault. The pack carries each as a one-piece kit, so the technician replaces rather than repairs.
The 2901990826 keeps the valve kits with the filter and separator kits so the 8000-hour service is one job. A planned valve renewal avoids the drift that a tired thermostatic element brings, and the machine holds the duty it was built for.
The Cubicle Filters and Wear Drain Kit
The last two kits of the 2901990826 close the service on the control side and the drain side. The KIT CUBICLE FILTERS renews the filters of the cubicle, and the KIT WEAR DRAIN renews the drain that wears with the hours.
Closing the Service
The cubicle filters of the 2901990826 protect the control air and the cabinet, and the wear drain kit renews the part that discharges condensate as it ages. Both are small parts with a large effect on reliability, and the pack includes them so nothing is left for a second order. The 8000-hour service is complete when the six kits are in, and the 2901990826 is the carton that holds them.
None of these kits is dramatic on its own, which is why the 2901990826 is a planned pack. A filter that stays past its interval, a separator that loads up, or a drain that no longer seats are all reasons to plan the service and keep the pack on the list.
Installation and Service Window
The 2901990826 arrives as one carton with the six kits inside, so the service replaces the whole set in a single step. The compressor is stopped and made safe, the kits are fitted in the order the service calls for, and the machine returns to duty with its 8000-hour items renewed.
Handling the 5.10 kg Pack
The 2901990826 weighs 5.10 kg, so it is a light carton that stores as a standing spare. The 60 × 30 × 25 cm box is the packed size, and the kits are laid out for the technician before the panels come off. A pack kept current on the list is the pack that fits when the interval arrives, and the service window stays inside the planned stop.
The 2901990826 is planned as a single-carton service. The machine record shows the 8000-hour mark, the pack is opened, and the six kits go in together. One confirmation covers the full renewal, so the workshop schedules the swap without waiting for a second item.
Ordering the 2901990826 Through Seadweer
Packs are ordered by record rather than by contents, because a service set of one programme can share a size while covering a different interval. The ordering routine of the 2901990826 is built around that fact.
Machine Record Check
Send Seadweer your compressor model and serial number, and the team checks the record against the 2901990826 before the quotation is issued. If your paperwork still shows an older number or a related kit, the check resolves it in the same pass, and the order is confirmed under the current production record.
What the Quotation Confirms
The quotation repeats the item data of the 2901990826: the description, the box figures and the complete six-kit scope of the order. One confirmation covers the whole service, so the workshop can schedule the swap without waiting for a second item. The 8000-hour set is planned and shipped under the one number the order travels under.

Tariq Al-Rashid –
We run our GA compressor in the 18-30 kW band and the 8000-hour service used to mean gathering several kits by hand. The 2901990826 put the full set in one order, and Seadweer matched it to our machine record before it shipped. The technician found every kit present, the swap went in during the planned window, and the compressor returned to its normal duty without a second parts call.
