Atlas Copco 2906049400 ZR450 16000H Maintenance Kit

Description

The 2906049400 is the Atlas Copco maintenance kit recorded for the ZR450 oil-free screw compressor, listed under the full designation ZR450 16000H MAINTENANCE KIT FOR OIL FREE COMPRESSORS. The kit is the parts scope for the 16000-hour service point of the machine: it arrives as one packed case that carries the mufflers, the valve-side kits, the membrane and the sealing hardware for that stop, so the service is planned and ordered as a single line instead of being assembled part by part.

A 16000-hour stop on an oil-free machine of the ZR class is one of the heavier service events in the maintenance calendar. The machine comes off load, the casings open at the valve and muffler positions, and every seal and rubber that the stop touches is renewed rather than inspected and reused. The 2906049400 exists so that this scope is complete before the shutdown begins, with each line checked against the packing list at the bench.

This page walks through the recorded contents of the kit, the components that carry their own part numbers and data, the machine the kit is recorded for, and the way a workshop plans the 16000-hour stop around it. The goal is that a maintenance planner can order the 2906049400, receive it, and put every line to work inside one planned window.

What the 2906049400 Kit Covers

The contents recorded on the official part page for the 2906049400 show the scope of the stop in seven lines:

Three of those lines are kits in their own right: the inlet valve kit, the check valve kit line, and the 4000H maintenance kit nested inside the larger case. The remaining lines cover the hardware that the stop renews in pairs and sets: two mufflers, one membrane, two O-rings and one set of rubbers. Read together, the seven lines describe a complete pass over the valve, muffler and sealing positions of the machine, which is exactly what the 16000-hour stop is planned around.

For the planner, the detail that matters is that the 2906049400 carries this scope as checked lines from the start. A missing O-ring or an unlabelled kit discovered mid-job is the one delay a planned shutdown cannot absorb, and the kit exists to keep that risk out of the schedule.

The Muffler Pair: 1830020479

The two MUFFLER lines of the 2906049400 are supplied under their own number, 1830020479. Each muffler is recorded with Germany as country of origin, 84879090 as its customs tariff code, a 200 × 90 × 90 mm frame and a weight of 715 gr. The pair travels in the kit as two boxed units, matched to the two muffler positions the 16000-hour stop renews.

The muffler is the part that stands in the path between the element stages, and it is renewed in pairs so the two sides of the circuit stay matched in condition. On the bench, the two 1830020479 units are checked against the packing list of the 2906049400 before the casings open, because the muffler positions are among the first accesses the stop takes.

Labelled Components with Their Own Data

Besides the muffler pair, the packages of the 2906049400 carry labels with their own recorded data. One labelled package reads 1614874799, with Germany as country of origin, 84212980 as its customs tariff code, a 146 × 99 × 97 mm frame and a weight of 657 gr. The number identifies the component against the machine parts list, and it is checked in at receiving like every other line of the kit.

A further label reads 1630040799, recorded as FILTER AIR and marked as packed under 1635040700. The component carries Germany as country of origin, 84213925 as its customs tariff code, a 490 × 400 × 400 mm frame and a weight of 8.4 kg, which makes it the largest single item to check in beside the 41.7 kg case of the kit itself.

The labels that were not clearly readable at receiving are not listed here. Every line of the 2906049400 is verified against the packing list that travels with the case, and that list remains the record for the parts that arrive without a legible label of their own.

The ZR450 and the 16000H Service Point

The application record names one machine: the 2906049400 is the 16000H maintenance kit of the ZR450, the large frame of the Atlas Copco oil-free screw compressor range. The designation carries the service marking directly in its name, and the kit is the parts scope recorded for that service point of the machine.

Within the ZR450 fleet, build variants and market versions still differ, and the serial number is what separates them. The parts list for each serial is the record that names the maintenance kit for that unit, and Seadweer confirms the 2906049400 against that list before an order is placed. A kit from a neighbouring service interval is not a substitute, because the scope it gathers belongs to a different stop.

Technical Specifications

The tables below collect the identification data and the physical figures recorded for the 2906049400.

Part Identification

Dimensions and Weight

The figures set a two-person handling case. At 41.7 kg in a 125 × 83 × 57 cm frame, the 2906049400 moves on a pallet or a trolley rather than by hand, and the case is positioned beside the machine before the stop begins so the lines can be checked in without re-handling. Seadweer confirms the current package details with the quotation.

Working the 16000H Service with the Kit

The contents of the 2906049400 are checked in at the bench before the machine comes off load, each line against the packing list. The three nested kits deserve their own check: the inlet valve kit, the check valve kit and the 4000H maintenance kit are opened at the bench and their own contents verified before the shutdown starts, because each of them covers a position the stop cannot leave half-done.

The muffler pair goes in as a matched set, the membrane and the O-rings take their positions with the sealing faces clean, and the rubbers are renewed where the stop opens the casings. The fastener and gasket scope inside the 4000H kit is consumed at the positions it was gathered for, so nothing from the old build returns to service by habit.

After assembly, the machine is run under observation before it returns to load, with the readings compared against the record of the previous stop. A short log of those readings, filed with the 2906049400 and the service date, is the baseline the next service interval starts from.

Ordering the 2906049400 Through Seadweer

Two pieces of information lock the order: the number on the kit or the machine file, which reads 2906049400, and the model and serial number from the compressor nameplate. Send both to Seadweer and the parts desk confirms the kit against the machine record, including the nested kits and the hardware lines it carries, in one pass.

Plants that run several ZR machines keep model, serial and kit number together in one record per unit. That record turns the next 16000-hour stop into a single confirmed message instead of a new investigation, and it keeps the service scope of each machine consistent across the fleet.

FAQ

Which compressor is the 2906049400 kit recorded for?

The kit is the 16000H maintenance kit of the ZR450 oil-free screw compressor, recorded under the full designation ZR450 16000H MAINTENANCE KIT FOR OIL FREE COMPRESSORS. The parts list for your machine serial number is the record that confirms the kit for that unit.

What is inside the 2906049400 kit?

Seven recorded lines: two MUFFLER units under 1830020479, one KIT VALVE INLET, one MEMBRANE, one check valve kit line, one KIT MAINT. 4000H, two O-RING units and one SET RUBBERS. The three kit lines carry their own contents and are checked in as boxed units.

What is the muffler number in the kit?

The two mufflers of the 2906049400 are supplied under 1830020479, each recorded with a 200 × 90 × 90 mm frame and a weight of 715 gr, with Germany as country of origin and 84879090 as the customs tariff code. The pair is renewed together so the two positions stay matched.

What does the 16000H marking mean?

It is the service marking carried in the official designation of the kit, and the kit is the parts scope recorded for that service point of the ZR450. The scope of the 16000-hour stop is exactly the seven lines the kit gathers.

What is the FILTER AIR 1630040799?

It is a labelled component of the 2906049400, recorded as FILTER AIR and marked as packed under 1635040700, with a 490 × 400 × 400 mm frame and a weight of 8.4 kg. It is checked in at receiving against the packing list of the kit.

How do I order the kit for my compressor?

Read the number on the kit or machine file, which reads 2906049400, and note the model and serial number from the compressor nameplate. Send both to Seadweer and the fitment is confirmed before the order is placed.
