\u0627\u0644\u0640 1616727581<\/strong> is the ELEMENT LP-T3, the low-pressure oil-free screw element that Atlas Copco lists for the ZR and ZT 30\u201355 VSD compressors, with the VSD+ and FLX builds of the same range drawing the stage through their own ordering code. It is the first compression step of a two-stage oil-free package, and it is renewed as a complete factory assembly rather than rebuilt in place.<\/p>\n

The stage carries one number in two printed forms. The item record names it as the 1616727581<\/strong>, and the same element is printed in the form 1616 7275 81 on the housing plate and across the build documents. It is listed as serialized, so a plate on each unit identifies it on its own rather than by family alone.<\/p>\n

This article sets out what the LP-T3 designation covers, which machines take the stage, how the two ordering routes work, and how fitment is confirmed before an order is placed.<\/p>\n

It converts shaft power into air flow at pressure, and it is a long-life factory assembly: the rotor pair, the housing and the bearings are built as one and renewed as one.<\/p>\n

What the LP-T3 Designation Covers<\/h3>\n

LP stands for the low-pressure position, the first compression step of the two-stage oil-free packages in the ZR and ZT ranges. T3 is the stage code Atlas Copco records for this element, and it separates the LP-T3 from the other stages of the same oil-free family.<\/p>\n

Atlas Copco prints the same number in two forms. The ten-digit form 1616727581 is what the item record carries, and 1616 7275 81 is the printed form used on the housing plate and the build documents. Both name the same stage, and either one can be used when a renewal is being confirmed.<\/p>\n

One Stage, Two Ordering Routes<\/h3>\n

\u0627\u0644\u0640 1616727581<\/strong> itself is the element, but the route an order takes depends on the build of the machine it goes into. Atlas Copco records one service kit reference for the ZR and ZT 30\u201355 VSD builds and a separate DT reference for the VSD+ and FLX builds of the same range.<\/p>\n

Both routes deliver the same stage position, so the practical question for a renewal is not which number is correct but which build the machine carries. That question is settled from the nameplate, and the sections below take each route in turn.<\/p>\n

Compressors That Take the 1616727581<\/h2>\n

The table below collects the documented coverage.<\/p>\n\n\n\n\n\n\n\n

The ZR\/ZT 30\u201355 VSD Range<\/h3>\n

The ZR and ZT 30\u201355 VSD compressors are oil-free rotary screw machines with variable speed drive, built for plants that cannot allow lubricant into the air they produce. In the parts records for these machines the 1616727581<\/strong> appears as the LP-T3 low-pressure element.<\/p>\n

The stage is the point in the package where oil-free air quality is first set, because everything the high-pressure stage receives passes through the low-pressure position before it.<\/p>\n

The VSD+ and FLX Builds<\/h3>\n

The VSD+ and FLX builds share the compression platform and the same low-pressure stage, and Atlas Copco records the 1616727581<\/strong> for them under their own ordering code rather than the VSD kit reference. The stage itself does not change between the builds; what changes is the reference an order is placed against.<\/p>\n

That distinction matters at the counter, not in the machine. A fitter reading the housing plate sees the same element number on every build in the range, and the build decides only which route the order follows.<\/p>\n

\u0644\u0645\u0627\u0630\u0627 \u064a\u062a\u0645 \u062a\u0623\u0643\u064a\u062f \u0627\u0644\u062a\u0648\u0627\u0641\u0642 \u0644\u0643\u0644 \u0622\u0644\u0629 \u0639\u0644\u0649 \u062d\u062f\u0629\u061f<\/h3>\n

The ZR and ZT oil-free ranges do not draw on a single element number. Different generations and configurations of the same model family carry different stage codes, and which one applies is decided by the build of the individual machine.<\/p>\n

\u0648\u0644\u0647\u0630\u0627 \u0627\u0644\u0633\u0628\u0628 \u0641\u0625\u0646 1616727581<\/strong> is confirmed from the parts list for a machine serial number rather than from the model name alone. Two machines that read almost the same on the badge can take different stages, and the record is what settles it.<\/p>\n

Ordering Through the Service Kits<\/h2>\n

Atlas Copco channels the renewal of this stage through two references, one per build. Neither reference replaces the element number; both name the route the order takes for a given machine.<\/p>\n

Kit 1837035000 for ZR\/ZT 30\u201355 VSD<\/h3>\n

For the ZR and ZT 30\u201355 VSD builds, the 1616727581<\/strong> is ordered through service kit 1837035000. The kit reference groups the stage with what the build needs around it, so the renewal arrives as one documented package for that machine family.<\/p>\n

Where a machine file carries the kit number, it describes the same stage position the element number names. Both references can appear in the same record, and they resolve to one stage.<\/p>\n

DT 8153349455 for VSD+ and FLX<\/h3>\n

For the VSD+ and FLX builds, the ordering reference is DT 8153349455. The DT prefix marks the route for those builds, and the 1616727581<\/strong> sits behind it exactly as it sits behind the kit reference on the VSD machines.<\/p>\n

Reading the build off the nameplate is what picks the route. Once the build is known, the reference follows, and the stage that arrives is the same LP-T3 either way.<\/p>\n

The Low-Pressure Position in a Two-Stage Unit<\/h2>\n

Oil-free packages of this range compress in two stages with cooling between them, and the two positions take different elements. The 1616727581<\/strong> is the low-pressure stage, the first compression step where ambient air is brought to an intermediate pressure.<\/p>\n

What the LP Stage Does<\/h3>\n

The rotor pair of the 1616727581<\/strong> turns in a precision-bored housing with nothing added to the compression chamber, so the air moving through it picks up no lubricant from the stage itself. Timing gears at the drive end hold the rotors in phase, and precision rolling bearings carry the shaft loads.<\/p>\n

The discharge of the low-pressure position feeds the second stage, so its output condition shapes what the whole package delivers. A stage renewed here restores the first half of that chain.<\/p>\n

Stage Pairing and the HP Position<\/h3>\n

The high-pressure position of the same machine draws a different element, recorded under its own number for each build. The two stages are ordered separately, and the parts list for the machine names each one.<\/p>\n

When a package reaches renewal age, both positions are read from the machine record rather than assumed together. The 1616727581<\/strong> covers the low-pressure position only, and its counterpart is confirmed the same way: from the parts list for the serial number.<\/p>\n

Handling the 90 kg Stage<\/h2>\n

At 90 kg and 45 \u00d7 45 \u00d7 52 cm, the 1616727581<\/strong> sits in the middle of the handling scale: too heavy to swing by hand, small enough to move with the gear most workshops already run. The figures describe the unit as it is supplied, and they shape the route from the unloading point to the machine.<\/p>\n

Dimensions and Moving Plan<\/h3>\n

The compact envelope reaches the machine on a pallet or in a case, and the openings it has to pass are measured in advance: doorway widths, lift capacity and the standing room in front of the machine. A hoist or engine crane rated for the 90 kg of the 1616727581<\/strong> covers the lift, and the slinging keeps the load level through the move.<\/p>\n

The stage is carried on its mounting faces and never on its shaft. Port caps stay in place until the moment of fitment, so nothing reaches the bore while the unit is exposed.<\/p>\n

Setting Down and the First Run<\/h3>\n

Before the machine is closed up, the mounting faces are cleaned and checked for burrs, the drive layout is inspected, and alignment and direction of rotation are confirmed. Once running, the machine is brought up unloaded and watched while the readings settle.<\/p>\n

Discharge temperature, pressure and vibration are logged through the first running period, and fasteners are re-torqued after the first hours. That short log becomes the baseline for every later check on the 1616727581<\/strong>.<\/p>\n

\u0639\u0644\u0627\u0645\u0627\u062a \u0627\u0644\u062a\u0622\u0643\u0644 \u0648\u0645\u0648\u0639\u062f \u0627\u0644\u062a\u062c\u062f\u064a\u062f<\/h2>\n

\u062a\u062c\u062f\u064a\u062f 1616727581<\/strong> is decided on condition rather than on a fixed hour count. Two lines of evidence carry most of that decision, and both read best as trends taken at a fixed interval rather than as single figures.<\/p>\n

\u0639\u0644\u0627\u0645\u0627\u062a \u0627\u0644\u062a\u062d\u0630\u064a\u0631 \u0627\u0644\u0645\u062d\u062a\u0645\u0644\u0629<\/h3>\n

The rotor coating is what changes first. As it wears, the running gap opens and the low-pressure stage delivers less air at the same shaft power, so a falling free air delivery measured at the rated pressure is the reading that follows that change. Discharge temperature at a steady load moves with it.<\/p>\n
