This is one of the larger stages in the oil-free screw range. Packed, the 1616635681<\/strong> measures 126 \u00d7 86 \u00d7 85 cm and weighs 904.00 kg, and Belgium is recorded as the country of origin. The item record lists the unit as serialized, which means a plate on each element identifies it on its own rather than by family alone.<\/p>\n

What the 1616635681 OFS Q-21 Element Is<\/h2>\n

It converts shaft power into air flow at pressure, and it is a long-life factory assembly rather than a consumable. When a stage reaches the end of its working life it is renewed as a complete unit, with the rotor pair, the housing and the bearings built as one.<\/p>\n

The interfaces on that assembly are set by the machine it was built for. Two stages can share a designation and still fill different positions on different builds, so the match is confirmed from the compressor record rather than from the code on the casting. That is why the 1616635681<\/strong> is ordered against a machine rather than against a description.<\/p>\n

The OFS Q-21 Designation<\/h3>\n

OFS is the oil-free screw designation, and Q-21 is the stage code Atlas Copco records for this element. The code is quoted in the parts records exactly as it stands, and it separates the Q-21 stage from the other stages of the same family. It is the first reference to check when a renewal of the 1616635681<\/strong> is being confirmed.<\/p>\n

The Plate on the Housing<\/h3>\n

It carries the part number and a unit number, and the same number appears in the printed form 1616 6356 81 across the shipping and build documents. Both forms name the same stage.<\/p>\n

Between the two, the unit number is the more specific. It links the stage to the record it was built under and to the compressor it was fitted to, which is the detail a machine file needs. Where several machines of one model stand side by side, the unit number is what keeps their histories apart.<\/p>\n

How an Oil-Free Screw Element Compresses Air<\/h2>\n

Oil-free compression starts from a simple condition: nothing inside the compression chamber of the 1616635681<\/strong> lubricates the rotors. The rotor pair turns in a precision-bored housing with the running gap held small enough to seal the pocket, and the two rotors stay apart instead of riding on each other.<\/p>\n

With no oil film carrying the load, timing gears at the drive end hold the rotor pair in phase. An anti-friction coating on the rotor surfaces protects them inside that non-contact gap, precision rolling bearings take the radial and thrust loads of the shafts, and a shaft seal keeps gear-end lubrication on the gear side of the 1616635681<\/strong>.<\/p>\n

The result is an air path with no lubricant to remove. Plants that run oil-free screw units work to air quality classes where oil must not enter the air at all, and the compression stage is the point where that condition is set. Everything downstream of the discharge port inherits the quality the stage of the 1616635681<\/strong> delivers.<\/p>\n

The envelope decides the access path. A stage of this size 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 turning space in front of the machine. The lifting gear is matched to the 904.00 kg of the 1616635681<\/strong>, and the slinging is arranged so the load stays level through the move.<\/p>\n

A second pair of hands at the machine is worth planning for. Setting a stage of this mass onto its faces is a controlled two-point operation, and the same care covers the removal of the unit being replaced. The 1616635681<\/strong> is handled the same way on the way out as on the way in.<\/p>\n

Fitment and the Machine Record<\/h2>\n

An oil-free package compresses in one stage or in two, with intercooling between them, and the position the 1616635681<\/strong> fills is fixed by the build of the machine. On a two-stage unit the low pressure and high pressure positions take different stages, and each of them is ordered by its own number.<\/p>\n

Interfaces the Renewal Must Match<\/h3>\n

The shaft end that takes the drive, the faces of the inlet and discharge ports and the mounting faces that set its position in the frame are all part of that build. A stage made for one position carries the port arrangement and the drive interface of that position, so the 1616635681<\/strong> does not move to another position unless the parts list for the serial number says it does.<\/p>\n

Air reaches the inlet after the filter and leaves the discharge towards the aftercooler and the treatment line, which puts the stage at the centre of the air path through the package. Seals and gaskets are renewed with the 1616635681<\/strong> rather than carried over from the unit coming out.<\/p>\n

Air-Side Readings<\/h3>\n

The rotor coating is what changes first. As it wears, the running gap opens and the stage delivers less air at the same shaft power, so 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

A stage that has to work harder for the same output draws more power for each unit of air. Recorded beside the delivery figure, that reading separates a worn 1616635681<\/strong> from a machine whose demand has simply changed.<\/p>\n

Mechanical Readings<\/h3>\n

Vibration at the bearing housings and the noise level around the 1616635681<\/strong> form the second line of evidence. Bearing fatigue develops slowly, and a single measurement says little on its own; taken at a fixed interval, the same reading becomes a trend.<\/p>\n

Left unchecked, bearing fatigue can end with the rotors touching, and at that point the stage is written off rather than renewed. A planned renewal avoids that outcome, because the unit is changed while the frame, the drive and the pipework are still in good order. The unit number recorded in the machine file is what makes the timing judgement on the 1616635681<\/strong> easier.<\/p>\n

Two pieces of information lock the order down: the number on the stage being replaced, which reads 1616635681<\/strong> or 1616 6356 81 in the printed form, and the model and serial number from the compressor nameplate. The nameplate matters because stage position and port arrangement differ across the builds that use this element family.<\/p>\n

What does the unit number on the 1616635681 record?<\/h3>\n

The item record lists the stage as serialized, so each 1616635681<\/strong> carries a part number and a unit number on its housing plate. The unit number links the stage to its build record and to the machine it was fitted to, and it is the reference to log in the machine file after a renewal.<\/p>\n

Which compressors take the OFS Q-21 stage?<\/h3>\n

The OFS Q-21 belongs to the oil-free rotary screw family, which covers stationary oil-free compressors. Stage position and port arrangement differ across those builds, so the parts list for your machine serial number is the record that confirms the 1616635681<\/strong> for your position.<\/p>\n

How is a 904.00 kg element handled on site?<\/h3>\n

The item data lists 904.00 kg in a 126 \u00d7 86 \u00d7 85 cm package, so the move is planned with lifting gear rated for that mass and an access route measured in advance.

Does an oil-free element ever need oil?<\/h3>\n

No oil enters the compression chamber of the 1616635681<\/strong>. The rotor pair runs in a non-contact gap held by timing gears, and gear-end lubrication stays behind the shaft seal, away from the air path.<\/p>\n

What readings show that the stage is due for renewal?<\/h3>\n

Possible signs can include falling free air delivery at the rated pressure, rising discharge temperature at a steady load, more power for each unit of air, and growing vibration at the bearing housings. Recorded at a fixed interval, those readings form the trend the decision is based on.<\/p>\n

How do I confirm the right stage for my machine?<\/h3>\n

Read the number on the stage being replaced and note the model and serial number from the compressor nameplate. Send both to Seadweer and the fitment is confirmed against the machine record before the order is placed.<\/p>\n
