El 1616738291<\/strong> is the Atlas Copco Service Air End OIS I-01, the complete exchange unit for the C80 oil-injected screw element<\/a>, and the official ERP lists it as the replacement for 1616738281<\/strong>. It serves the smaller frames of the oil-injected GA range, with confirmed applications on the GA18, GA22, GA26, GA26 VSD+, GA26+ and GA30.<\/p>\n

The unit is a full air end rather than a set of internal parts. It arrives as a serialized assembly with its own nameplate, it is exchanged as one piece, and the old unit goes back to the bench for the comparison that closes the job. The ERP records it in the rate group S3K Oil injected screw, Element, Belgium as the country of origin.<\/p>\n

En este art\u00edculo se explica qu\u00e9 es el 1616738291<\/strong> is, how the number chain runs from the earlier item to the current one, which machines it is recorded for, and how the exchange is planned and ordered.<\/p>\n

What the 1616738291 Service Air End Is<\/h2>\n

El 1616738291<\/strong> is listed as SERVICE AIR-END OIS I-01 in the Atlas Copco parts programme. The OIS I-01 designation is the oil-injected screw element of the I-01 size, and the C80 family code is the one the machine records use for the element line that serves this class of machines.<\/p>\n

A Complete Exchange Unit<\/h3>\n

A service air end is exchanged as a whole. The compression element, its shafts and its bearing positions arrive assembled and checked, so the machine receives a renewed compression core in one piece of work instead of an open rebuild on the shop floor.<\/p>\n

The ERP marks the 1616738291<\/strong> as a serialized item. The nameplate on the unit carries the part number, the serial number and the country of build, and that plate is the identity the workshop checks against the order before the package is opened.<\/p>\n

The C80 I-01 Element<\/h3>\n

The machine records tie this line to the element description C80 I-01. That description is what appears on the official machine record for the XAS87KD and in the parts documents of the GA frames listed below, and it is the common thread that connects the numbers in the chain.<\/p>\n

The element is the core of an oil-injected screw machine. Two rotors turn in a filled chamber, the oil seals the clearances and carries the heat away, and the output of the machine follows the condition of the element. Wear at the rotors and bearings opens the working clearances, and the exchange of the air end is the way the programme restores it.<\/p>\n

The Number Chain from 1616738281 to 1616738291<\/h2>\n

The numbers around this air end form a short chain, and each number has its own role. The official ERP carries the direct replacement: 1616738281<\/strong> is replaced by 1616738291<\/strong>, the service air end ordered today.<\/p>\n

The Official Replacement<\/h3>\n

The Parts List of the GA30 shows the chain in one line. Section 3.8, Element GA 30, lists the element under 1616738281<\/strong> with the instruction that it is substituted by 1616738291<\/strong> SERVICE AIR-END OIS I-01. A plant that holds the older number on a drawing or an invoice reaches the same unit through that line.<\/p>\n

The Wider Number Set<\/h3>\n

Two further numbers sit in the same line. The number 1616738290<\/strong> appears as the OLD number beside the 1616738291<\/strong> NEW on an official purchase file for a GA26+, and 1616738280<\/strong> is the number the machine records carry for the C80 I-01 element itself. The table collects the four numbers and their roles.<\/p>\n\n\n\n\n\n\n\n

The chain is read in one direction. Machines and documents that carry an older number reach the 1616738291<\/strong> through the replacement line, and the current number is what goes on the order.<\/p>\n

Machines the 1616738291 Is Recorded For<\/h2>\n

The confirmed applications cover six machines of the smaller oil-injected GA range. The evidence differs in level, and the strongest record stands on the official Parts List.<\/p>\n

GA30, the Official Parts List Record<\/h3>\n

The GA30 is the cleanest record of the set. The Atlas Copco Parts List carries its own section for the element, and that section lists 1616738281<\/strong> substituted by the 1616738291<\/strong> service air end. The application needs no inference: the machine, the position and the number appear on one official page.<\/p>\n

GA26+, the Purchase File Record<\/h3>\n

The GA26+ application is documented by an official purchase file of a water utility. The file names the machine as GA26+ of the model GA26P_18 with the serial APIS45159909, and it orders the air end under 1616738291<\/strong> NEW with 1616738290<\/strong> as the OLD number. A real machine of this type therefore took the current service number in service.<\/p>\n

GA18, GA22, GA26 and GA26 VSD+<\/h3>\n

The remaining four machines are documented by equipment-level records. A spare parts record for a GA18-80 compressor lists a new C80 I-01 air end under the 1616738291<\/strong> number. A data sheet of a GA22-125 AP unit lists the element line with 1616738280, 1616738290 and 1616738291<\/strong> together. Parts documents of the GA26 place 1616738290 on the C80 I-01 element line, and matching records for the GA26 VSD+ follow the same chain to the current number.<\/p>\n\n\n\n\n\n\n\n\n\n

The XAS87KD Record<\/h3>\n

The official machine database carries an XAS87KD RENTAL unit with the C80 I-01 element against it, listed under the number 1616738280<\/strong>. That record confirms the element family of the machine, but the collected material holds no direct record of the 1616738291<\/strong> service air end for the XAS87KD itself.<\/p>\n

The number therefore stays out of the application table above. A plant running an XAS87KD sends the serial number with the enquiry, and the parts desk settles the exchange number from the machine record before the order is written.<\/p>\n

Reading the Air End Before the Exchange<\/h2>\n

The exchange is a planned job, and the decision is taken on the readings of the machine and the hours of the air end.<\/p>\n

Las lecturas que determinan la decisi\u00f3n<\/h3>\n

Free air delivery at the rated pressure is the first reading to fall when the element wears. Discharge temperature follows, because air that leaks back across the clearances is compressed more than once, and the power drawn per unit of air rises with the same wear.<\/p>\n

Read at fixed intervals, the trend tells a plant whether the 1616738291<\/strong> belongs in the next planned stop, while the machine still delivers inside its rated band.<\/p>\n

The Nameplate and the Serial Number<\/h3>\n

The air end is a serialized unit, and its nameplate is the identity of the job. The plate on the new unit is checked against the order before the package is opened, and the serial of the outgoing unit is recorded in the machine file with the date of the exchange.<\/p>\n

Plants that keep this record build a traceable history of the element line on each machine, and the next enquiry is settled from that file in one step.<\/p>\n

Resumen del intercambio<\/h2>\n

The work divides into taking the old air end out, fitting the 1616738291<\/strong>, and the first run under observation. On this class of machine the exchange is a one-shift job with ordinary workshop equipment, at 58 kg on a 39 \u00d7 34 \u00d7 28 cm footprint.<\/p>\n

Taking the Air End Out<\/h3>\n

The machine is isolated, vented and locked out, the oil lines are drained and capped, and the drive and the pipework are freed. The air end comes off its mounts as a unit and moves to the bench, where the nameplate is read and photographed for the machine file.<\/p>\n

The old unit is kept until the new one is confirmed against it, which is the last point at which a wrong-number exchange is caught with the machine still complete.<\/p>\n

Fitting and the First Run<\/h3>\n

El 1616738291<\/strong> goes in on the same mounts, the oil lines and the pipework are closed in the reverse order, and the rotation and the oil level are confirmed before the start. The machine runs unloaded under observation, and discharge temperature, pressure and delivery are logged through the first running period.<\/p>\n

That log becomes the baseline of the new element, and the serial number of the 1616738291<\/strong> goes into the machine file beside it.<\/p>\n

Ordering the 1616738291<\/h2>\n

The current number is what the order carries, whatever number the plant holds on paper.<\/p>\n

Qu\u00e9 hay que enviar junto con la solicitud de informaci\u00f3n<\/h3>\n

Send Seadweer the compressor model and serial number together with whichever of the chain numbers is at hand. The team confirms the exchange unit for the machine, the replacement line from the older number, and the gaskets and small parts the stop calls for.<\/p>\n

The confirmation comes back with the identity line the workshop will check at the bench, so the nameplate on the unit is verified against a known order before the work begins.<\/p>\n

Preguntas frecuentes<\/h2>\n

What is the difference between 1616738281 and 1616738291?<\/h3>\n

El 1616738281<\/strong> is the earlier item in the official ERP, and the 1616738291<\/strong> is the service air end that replaces it. A plant holding the old number on a drawing reaches the same unit through the replacement line, and the current number goes on the order.<\/p>\n

Which machines take the 1616738291?<\/h3>\n

The confirmed applications are the GA30, the GA26+, the GA18, the GA22, the GA26 and the GA26 VSD+. The GA30 stands on the official Parts List, the GA26+ on an official purchase file with the machine serial, and the rest on equipment-level records.<\/p>\n

Does the 1616738291 fit the XAS87KD?<\/h3>\n

The official machine record for an XAS87KD lists the C80 I-01 element under 1616738280, and the collected material holds no direct record of the 1616738291<\/strong> for that machine. The serial number settles the exchange number at the parts desk before an order is written.<\/p>\n

What arrives with the 1616738291?<\/h3>\n

The unit arrives as a complete, serialized air end with its nameplate carrying the part number, the serial number and the country of build. The plate is checked against the order before the package is opened, and the serial enters the machine file at the exchange.<\/p>\n

What does the C80 I-01 designation mean?<\/h3>\n

It is the element line the Atlas Copco machine records use for this class of oil-injected screw element, and it is the description that ties the numbers of the chain together. The OIS I-01 in the item description names the same element in the service programme.<\/p>\n

How is the 1616738291 ordered?<\/h3>\n

Send Seadweer the compressor model and serial number with the number at hand, old or new. The team confirms the unit for the machine, the replacement line, and the small parts the stop calls for alongside the air end.<\/p>\n
