Atlas Copco 1303032090 S67 OIS H-72 Screw Element

Description

The 1303032090 is the Atlas Copco S67 oil-injected screw element, listed in the item data under the designation S67 OIS H-72 SPARE. It is the compression stage of a screw compressor rather than a consumable, and it carries two further references in the parts records: the production number 1303032080 and the current ordering number 1303033090. This article sets out the identity of the 1303032090, the numbers that travel with it, the working principle of the stage and the figures you need before ordering.

Identity of the 1303032090 Element

An element is the heaviest spare a compressor owner orders, and its identity rests on the designation in the item record and on the numbers that travel with it. For the 1303032090 the record carries one designation and two further references, and reading them together is what keeps an order on track.

What the S67 OIS H-72 Designation Covers

The item data lists the 1303032090 as S67 OIS H-72 SPARE. The S67 names the element family, the OIS marks the stage as oil-injected screw, and the H-72 gives the version within that family. The spare suffix records the part as a service stage rather than a factory assembly item.

The same record places the 1303032090 in the rate group S3K Oil injected screw, Element, which is where the item sits in the compressor parts classification. That group is the one an order travels under, and it confirms the 1303032090 as a compression element rather than a filter, a valve or a control part.

At 37 × 23 × 20 cm and 32.04 kg as packed, the 1303032090 is a two-person handling job with lifting gear rather than a bench item. The figures belong in the machine file beside the identification, because they set the lifting plan for the fitting day.

The Production Number 1303032080

The 1303032090 is also recorded under the production number 1303032080. The production number is the reference used when the element is fitted to new machines at the factory, while the service number is the order code used when the element is ordered as a spare.

Both numbers name the same S67 element, and a machine file can carry either one. When a record shows 1303032080, the enquiry that follows still reaches the same stage, and Seadweer reads the pair as one identification rather than as two parts.

Keeping both references in the file matters at the point of ordering, because a workshop reading the production number off an assembly drawing and a planner reading the service number off a spare-parts list are looking at the same item. The 1303032090 is the reference this article uses throughout.

Where Orders Go Today: the 1303033090

Atlas Copco directs current orders for this stage to the 1303033090, the H-73 version of the S67 element. The direction follows a version step within the family: the H-72 stage listed here is the reference in the documentation of machines already in service, and the current order code is the H-73 stage.

In practice the ordering conversation runs in two steps. A plant reads the code on the old element tag, finds the 1303032090 or the production number 1303032080 in its records, and the order is then placed under the current 1303033090. Seadweer performs that check with every quotation, so the number in the machine file and the number on the order do not contradict each other.

Nothing about the direction changes the position of the stage in the machine. The 1303032090 stays the compression stage of the compressor, and the machine documentation keeps the 1303032090 as its element reference.

What the Screw Element Does in the Compressor

The 1303032090 is an oil-injected rotary screw element, the air end that turns drive power into compressed air. Its working principle explains both its efficiency and its service profile.

Two intermeshing helical rotors spin inside a precision-bored housing. Injected oil seals the running clearances between the rotors and the housing, carries the compression heat away and lubricates the bearings, so the rotors stay separated by an oil film rather than by metal-to-metal contact.

Air enters the stage after filtration, is compressed along the rotor path and leaves at working pressure, and the oil is removed downstream by the separator of the host machine. Because the oil does three jobs at once, the stage holds its efficiency over long runs, and wear concentrates in the bearings rather than in the rotors themselves.

The element is also the part of the compressor that most affects its running cost. Compression work is where the energy of the machine is spent, so the condition of the rotors, the housing bore and the bearing set is what decides how much power the machine needs for each cubic metre of air it delivers.

The S67 Element in the Oil-Injected Family

The 1303032090 belongs to the oil-injected rotary screw family, and the family sets the machine classes the stage serves.

Oil-Injected Element Characteristics

An oil-injected element differs from an oil-free stage in how it seals the gap between the rotors. Oil injection does the sealing in this design, while an oil-free stage relies on a coated rotor pair held in phase by timing gears.

Two consequences follow for the 1303032090. The oil circuit of the host machine is part of its working environment, so oil quality and separator condition belong to the service life of the element. Its bearings also carry the rotor loads through an oil film, which is why bearing condition is the reading that drives renewal decisions on the 1303032090.

The Machine Classes It Serves

The 1303032090 is associated with oil-injected rotary screw compressors in general plant duty, where a single compression stage carries the air demand of the site. The element is renewed as a complete serviced unit when its service life is reached, rather than being rebuilt on site.

Because the version and the machine build decide the exact stage, the fitment is confirmed from the machine rather than from the family name. Send Seadweer the old tag code, the compressor model and the serial number, and the stage for your build is identified from the records of the 1303032090 and the current ordering number.

Wear Signs and Renewal Timing

An element of this class announces its aging through measured trends long before it fails outright, and the trends are readable with the instruments most plants already run.

Possible Warning Signs

Possible signs of element wear can include rising specific energy, drifting discharge pressure, unusual noise or vibration, higher oil temperature and metal traces in the oil sample. Specific power often climbs first, because widening internal clearances let compressed air slip back instead of leaving the stage.

Any one of those trends is a reason to inspect the element and plan the renewal. On a machine that carries a whole production section, the inspection is worth doing before the next planned stop rather than during a breakdown.

Timing the Renewal

Oil-injected elements commonly reach their first major bearing service somewhere in the 20,000 to 40,000 running-hour range as a family-level reference, but the real timing follows the condition of your machine and the service documentation that applies to it rather than a fixed hour target.

Vibration checks, oil analysis and temperature trends predict bearing condition long before a fixed count is reached. A planned renewal with the 1303032090, ordered under the current ordering number, beats an unplanned stop, because bearing fatigue left alone can let the rotors seize, which in most cases writes the element off instead of allowing a repair.

Handling the Element Into the Machine

At 32.04 kg and 37 × 23 × 20 cm as packed, the 1303032090 is a lifting job with a clear route from the store to the machine, and the figures belong on the plan for the fitting day.

The 1303032090 is moved with lifting gear and kept sealed until it is at the machine, because the rotor bore and the shaft end are the two faces that set the running clearances of the element. The mounting face of the host machine is cleaned before the stage goes in, and the drive coupling is aligned to the element shaft.

Once the 1303032090 is in place, the oil circuit of the machine is refreshed and the separator is checked at the same visit. The element is then run in under observation, so the pressure band and the oil temperature settle back to their normal readings before the machine returns to full duty.

Ordering Through Seadweer

Two references and one ordering direction are enough to make the order unambiguous, and the check that ties them together is worth one message.

Read the code on the old element tag, note the compressor model and the serial number, and send all three to Seadweer together with the item number 1303032090. The team checks the number against the machine build and confirms the order under the current 1303033090, with the production number 1303032080 kept in the records beside it.

One pass of verification removes the wrong-stage risk entirely, and it is the same check that keeps the machine file, the order and the delivery all pointing at the one element your compressor needs.
