Atlas Copco 2906064500 ZR500 VSD 16000H Maintenance Kit

Description

The 2906064500 is the Atlas Copco maintenance kit recorded for the ZR500 VSD oil-free screw compressor, the parts scope for the 16000-hour service point of that machine. The kit arrives as one packed case that carries ten recorded lines: the muffler, the valve-side kits, a nested 4000H maintenance kit, the sealing hardware, and the brush set that belongs to the variable speed drive of this machine class.

That brush set is what separates this kit from the maintenance kits of the fixed-speed ZR frames. A VSD machine regulates its motor through power electronics, and the drive side carries wear parts of its own: the 2906064500 gathers the EARTHING BRUSH ZR400/900 and the ZR500-900VSD CARBON BRUSH in the same case as the mechanical scope, so the electrical and mechanical sides of the stop are ordered together instead of through separate investigations.

This page follows the case of the 2906064500 from the recorded contents outward: the nested 4000H kit with its own part number, the check valve kit with its own contents, the brushes and their designations, the single muffler, and the machine the 16000-hour stop is planned around. Every figure below is drawn from the official part data, so the tables can be used directly at the bench and in the machine file.

What the 2906064500 Kit Covers

The contents recorded on the official part page for the 2906064500 show the scope of the stop in ten lines:

Three of the ten lines are kits or named assemblies with identities of their own: the nested 4000H kit, the check valve kit, and the inlet valve kit. The brush lines carry the designations of the drive side, and the remaining hardware renews the sealing and wearing positions the stop opens: two O-rings, one set of rubbers, two sets of wearing parts and one membrane.

Read as a whole, the ten lines of the 2906064500 describe one complete pass over the mechanical, pneumatic and electrical wear points of the machine at the 16000-hour mark.

For the planner, the ten lines are also the receiving checklist. Each line of the 2906064500 is verified against the packing list before the machine comes off load, and the three kit lines are opened at the bench so a missing spring or washer is found before the shutdown starts, not during it.

The Nested 4000H Kit: 2906064300

The line ZR500 VSD 4000H MAINTEN. KIT is supplied inside the 2906064500 case under its own number, 2906064300. The official part page records it as the ZR500 VSD 4000H maintenance kit for ZR and ZT oil-free compressors, with Belgium as country of origin, 84813099 as its customs tariff code, an 840 × 730 × 430 mm frame and a weight of 25.6 kg — the bulk of the 16000H case in a single boxed kit.

Its own contents page lists five lines, and each one maps to a service position of its own:

The filter element and the air/oil filter kit are the filtration scope of the 4000H cycle, the valve line renews a valve position in its own right, and the Dowty seal washer and the membrane close the sealing points the stop opens. Inside the 2906064500, this whole 4000H scope travels pre-assembled as one line: the planner orders the 16000-hour kit and the filtration cycle arrives inside it, checked against the same packing list.

The Check Valve Kit: 2906054100

The +4++ CHECK VALVE KIT+ line of the contents table is supplied under its own number, 2906054100, recorded as the check valve kit for oil-free compressors. The kit is a light one — 100 g in a 100 × 100 × 20 mm frame — and its own contents page lists five lines: one SPRING, two RING units, four LUG BEARING units, two SPRING SLEEVE units and two PIN units.

The contents of the 2906054100 describe a complete rebuild set for a check valve of this class: the spring and its sleeve carry the closing force, the rings and the pins locate and retain the moving parts, and the four lug bearings take the wear at the pivots.

When the 2906054100 is opened at the bench, the twelve small parts are counted against the list before the valve they serve is disassembled. A check valve rebuilt with a missing bearing is a fault discovered at restart rather than at the bench.

Brushes for the VSD Drive

Two lines of the 2906064500 belong to the electrical side of the machine. The EARTHING BRUSH ZR400/900 is recorded by its designation across the ZR400 to ZR900 frames, and the ZR500-900VSD CARBON BRUSH is designated for the VSD builds of the ZR500 to ZR900 range. Both travel in the case as single units, and both are renewed at the stop rather than measured and reused.

Their presence in a mechanical maintenance kit is the practical fingerprint of the VSD concept: the drive that varies the motor speed carries brushes that wear with the hours, and the 16000-hour stop is the point where the parts list renews them together with the rest of the machine. A workshop that services the ZR500 VSD keeps both designations in the machine file beside the 2906064500 number, so the next stop starts from a complete record.

One Muffler: 1830020479

The MUFFLER line of the 2906064500 is a single unit, supplied under the number 1830020479 — the same muffler reference recorded across the 16000H kits of the ZR oil-free frames. It carries Germany as country of origin, 84879090 as its customs tariff code, a 200 × 90 × 90 mm frame and a weight of 715 gr, and it is renewed where the 16000-hour stop opens the muffler position of the machine.

The single line is worth a note against the kit structure: where the fixed-speed sister kits of this class renew mufflers in pairs, the 2906064500 records one muffler and puts the difference into the drive-side brushes. The parts list of each machine decides that split, and the serial number of the unit confirms which structure applies before the order is placed.

Technical Specifications

The tables below collect the identification data and the physical figures recorded for the 2906064500.

Part Identification

Dimensions and Weight

The figures set the handling plan for the stop. At 30.7 kg in a 120 × 80 × 90 cm frame, the 2906064500 moves on a pallet or a trolley, and the case is positioned beside the machine before the shutdown so the ten lines can be checked in without re-handling. Package details for the current build are confirmed with the quotation.

Planning the 16000H Stop on the ZR500 VSD

The 2906064500 is recorded for one machine, the ZR500 VSD, and the 16000-hour mark is where its parts list calls for the full scope in this case. Build variants and market versions still differ within the fleet, and the parts list for each serial is the record that names the kit for that unit — the reference Seadweer confirms before any order for the 2906064500 is placed.

On the bench, the work follows the three layers of the 2906064500 case. The nested 4000H kit covers the filtration cycle first, the valve-side kits and the muffler take the pneumatic positions, and the brushes close the drive-side scope that only a VSD machine carries. The sealing hardware — the O-rings, the rubbers, the wearing parts and the membrane — is consumed at every position the stop opens, 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 filed beside the 2906064500 and the service date. Plants that run several ZR machines keep that record per unit, which turns the next 16000-hour stop into a single confirmed message to the parts desk instead of a fresh investigation.

FAQ

Which compressor is the 2906064500 kit recorded for?

The kit is the 16000H maintenance kit of the ZR500 VSD oil-free screw compressor, recorded under the designation in the table above. The parts list for your machine serial number is the record that confirms the kit and the ten lines it gathers for that unit.

What is inside the 2906064500 case?

Ten recorded lines: one MUFFLER, the EARTHING BRUSH ZR400/900, the +4++ CHECK VALVE KIT+, one KIT VALVE INLET, the ZR500 VSD 4000H MAINTEN. KIT, two O-RING units, the ZR500-900VSD CARBON BRUSH, one SET RUBBERS, two SET OF WEARING PARTS and one MEMBRANE.

What is the nested 4000H kit?

The nested line of the 2906064500 is supplied under its own number 2906064300, with Belgium as origin and 84813099 as its customs tariff code. Its five contents lines cover the filter element, the air/oil filter kit, a valve, a Dowty seal washer and a membrane.

Why does this kit contain brushes?

The ZR500 VSD regulates its motor through a variable speed drive, and the drive side of the 2906064500 carries the EARTHING BRUSH ZR400/900 and the ZR500-900VSD CARBON BRUSH as wear parts of the machine. The 16000-hour parts list renews them together with the mechanical scope, which is why both travel in the same case.

What does the check valve kit contain?

The kit travels inside the 2906064500 under its own number 2906054100 and lists five contents lines: one SPRING, two RING units, four LUG BEARING units, two SPRING SLEEVE units and two PIN units — twelve small parts in a 100 g kit of 100 × 100 × 20 mm.

What does Seadweer need to confirm the order?

The kit number, which reads 2906064500, and the model and serial number from the compressor nameplate. Send those two details to Seadweer and the parts desk confirms the kit against the machine record before the order is processed.
