Atlas Copco 1616724890 Service Stage Air End C106 OMCO

Descripción

Oil-free compressed air is a promise that is kept or lost at the compression stage, because that chamber is the one place the process air cannot avoid. The 1616724890 is the service-stage air end Atlas Copco records for that duty across the AQ range: description SERVICE STAGE AIREND C106 OMCO, rate group S3L Oil free screw, Element, country of origin Belgium. Oil-free screw elements compress air without oil in the chamber, and the 1616724890 is the renewed stage ordered when one of them comes up for service.

The C106 designation places this stage within the Atlas Copco oil-free element range, and the full description SERVICE STAGE AIREND C106 OMCO is recorded exactly as the parts system lists it. The element measures 58 x 36 x 32 cm and weighs 107 kg, a cast assembly delivered complete and ready to seat on the original mounts. Each unit carries its own serial number, which ties the stage to the machine record it was built for.

Product overview

An air end is the component that turns shaft power from the motor into compressed air, and in a screw machine that work happens between two meshing rotors. Every figure a user reads on the compressor nameplate, from free air delivery to specific power, is set by how this one stage performs. In the oil-free AQ machines the 1616724890 holds that role as the C106 element.

The word service in the parts description marks the ordering channel rather than a lesser build. Machine documentation lists the element fitted at the factory, while a renewal during service is ordered under the service-stage number the parts system holds for that duty. The 1616724890 is that number for the AQ oil-free machines whose parts lists call for the C106 element.

Technical specifications

The record for the 1616724890 carries the fields below as the Atlas Copco parts system lists them. These values travel with the part through ordering, into the service bay and onto the maintenance file.

Part identification

Dimensions and weight

Each 1616724890 measures 58 cm in length, 36 cm in width and 32 cm in height, with a recorded weight of 107 kg. The cast housing accounts for most of that mass, so the stage travels and is moved with lifting gear rather than by hand.

Inside the oil-free compression stage

Rotors, coating and timing gears

An oil-free screw element runs with no oil in the compression chamber, so the rotors turn in a non-contact gap protected by an anti-friction coating on their working surfaces. Timing gears hold the phase between the rotor pair, keeping the profiles from touching through the full sweep. That layout is what separates an oil-free stage from an oil-injected one, where oil does the sealing.

In the 1616724890 this design keeps the air path free of lubrication from inlet to discharge. The air leaving the stage stays outside the oil circuit entirely, which is what lets the AQ machines hold the ISO 8573-1 Class 0 purity level their rating is built on.

Housing, bearings and shaft seal

The housing is a precision-bored casting that holds the rotor clearance, and the rotor pair runs in precision rolling bearings that carry both radial and thrust loads. A shaft seal keeps drive-side lubrication away from the air side, holding the boundary the stage exists to protect. None of these internals are reconditioned in the field.

When coating wear or a performance drop appears, the element is exchanged as a complete assembly rather than stripped down. That exchange practice is the reason the 1616724890 exists as a service-stage part with its own ordering identity.

Traceability and serialization

El 1616724890 is recorded as a serialized item, so each unit carries its own factory identity through the supply chain. The serial on the plate ties the physical stage to the build and quality record behind it, from assembly through to the service event where it is fitted.

For the buyer, serialization shows up at the confirmation step. A serialized stage is checked against the compressor model and serial rather than matched by size, because one element family can serve several builds. Seadweer runs that check against the machine record before the 1616724890 is ordered.

Fitment across the AQ oil-free range

El 1616724890 is listed for the oil-free screw compressors of the AQ range. The confirmed fixed-speed models are AQ 30 (W), AQ 37 (W), AQ 45 (W) and AQ 55 (W), and the variable-speed line runs from AQ 37 VSD through AQ 55 VSD. The (W) suffix marks the water-cooled version of each size.

These machines share the C106 element platform, which is why a single service-stage number covers the group. Fitment for an individual machine is still read from the parts list of its serial, so the 1616724890 is ordered by model and serial rather than by a visual match to the removed unit.

Installation and service planning

Handling a 107 kg cast stage

El 1616724890 weighs 107 kg as a complete cast assembly, so the move from transport to the machine runs on lifting gear with a clear path. The stage seats on the original mounts, and the inlet and discharge ports meet the existing pipework without modification.

Installation is scheduled inside a planned shutdown once the stage is confirmed. Aligning the housing to its original position protects the rotor clearance, and the machine returns to stable delivery after the restart.

Reading the condition of the stage

Oil-free elements are renewed on condition rather than at a fixed hour count. A rise in specific energy, drifting discharge pressure, unusual noise or vibration, and a higher running temperature at the stage are the signals that turn a renewal into a planned line item.

Vibration checks and temperature trends read the condition of the 1616724890 long before any calendar date would. Recording those trends at each service stop keeps the next exchange inside a shutdown that was chosen, not one that chose itself.

Preguntas frecuentes

What does the C106 designation on the 1616724890 mean?

C106 is the element model within the Atlas Copco oil-free element range, and the 1616724890 is the service-stage ordering identity for that element. The full description SERVICE STAGE AIREND C106 OMCO is recorded by the parts system exactly as printed.

Which compressors take the 1616724890?

The confirmed models are AQ 30 (W), AQ 37 (W), AQ 45 (W) and AQ 55 (W), plus the variable-speed AQ 37 VSD through AQ 55 VSD. Fitment for a specific serial is read from its parts list before the order is placed.

Why is the element exchanged as a complete stage?

The rotors, coating, bearings and clearances are set at the factory as one matched assembly, and none of the internals are reconditioned in the field. Exchange keeps the 1616724890 returning the machine to its rated delivery and purity in one planned stop.

What purity does the machine hold with this element fitted?

The compression chamber runs without oil, so lubrication never enters the air path. That is the basis on which the AQ oil-free machines deliver air at the ISO 8573-1 Class 0 level.

What are the recorded dimensions and weight?

Each 1616724890 measures 58 cm long, 36 cm wide and 32 cm high, with a weight of 107 kg. The cast housing makes lifting gear part of the installation plan.

How is the 1616724890 confirmed for my machine?

Send the model and serial number from the compressor nameplate, and the parts list for that serial names the service-stage air end. The 1616724890 is confirmed against that record before the order is placed, never matched by appearance.

Genuine supply from Seadweer

When a renewal is planned for an AQ oil-free machine, send the model and serial number so the stage is confirmed against the build record before anything moves. Each serial carries its own parts list, and the nameplate holds everything that check needs. The 1616724890 ordered this way arrives as the stage that record names.

Seadweer supplies the 1616724890 as the genuine Atlas Copco service-stage air end, with the description, rate group, origin and tariff recorded exactly as the parts system lists them. A confirmed number also keeps the maintenance file accurate, because the element on record and the element in the machine stay the same thing. Send the machine details, and the stage is checked and prepared for the planned stop.
