The 1616716187 is the OFS O-27 oil-free screw element, a compression stage built for the large end of the Atlas Copco oil-free screw range. Two numbers tell the scale before any catalog is opened: 99 x 80 x 68 cm of packed length, width and height, and 548 kg on the scale. An element of this class carries the full compression duty of a production-scale air supply, and everything about its service \u2014 from the renewal decision to the lifting plan \u2014 follows from that scale. Its defining property, however, is the same as in every Atlas Copco oil-free stage: the compression chamber stays dry, and no oil enters the air path at any point in the cycle.<\/p>\n

This page records the identification and physical data for the 1616716187, explains what the OFS designation stands for, and works through the renewal of a large-format element: how wear shows in the operating data, what the handling of a 548 kg stage involves, and how the ordering reference closes the identification. It is written for maintenance planners and parts buyers responsible for oil-free plant where the air end is not a component one person moves, but a unit the schedule is built around \u2014 and where every step of that schedule, from quotation to fitting, keys on the 1616716187 itself.<\/p>\n

What OFS O-27 Stands For<\/h2>\n

OFS is the Atlas Copco family mark for Oil-Free Screw elements. The letters place the unit in the oil-free screw branch of the range \u2014 helical rotor pairs compressing in a dry chamber \u2014 and the letter and number after the mark identify the size class within that branch. O-27 therefore does two jobs at once: it names the family the unit belongs to and it places the 1616716187 at the large end of that family’s size ladder. The element carries both identifiers, OFS O-27 on the documentation and the complete ordering number on the plate.<\/p>\n

For purchasing, the complete number is the reference that counts. Quotations, order confirmations and the parts documentation all key on the 1616716187, and quoting it in the first message settles identification before any discussion starts. The designation describes the component; the number selects the exact unit. An enquiry that carries the full number arrives at the parts desk already identified, which matters more at this scale than at any other \u2014 a large element is planned weeks ahead, and no planner wants identification questions inside that timeline.<\/p>\n

The plate on the element remains the anchor. A clear photograph of the plate, taken while the machine is open for routine service, records the complete 1616716187 reference together with the serial number, and those two lines are everything the parts desk needs to prepare the next quotation. At this scale the photograph also serves the maintenance file: when the renewal is eventually planned, the file states exactly which 1616716187 is fitted, when it went in, and what the lifting arrangement will face.<\/p>\n

Each 1616716187 leaves the factory serialized, and the number on the plate ties the physical unit to its documentation through installation and every service event after it. The dimensions above describe the element itself; the crate it ships in adds clearance around those figures, and the handling plan accounts for both. Keeping the serial and the 1616716187 reference together in the machine’s maintenance file keeps the element’s history readable for the next renewal.<\/p>\n

The Oil-Free Screw Principle at Large Format<\/h2>\n

The compression cycle of the 1616716187 follows the oil-free screw principle: air enters the inlet, twin helical rotors reduce its volume as their chambers turn past the housing, and the compressed air leaves through discharge with no injected oil anywhere in the path. The rotors run in a non-contact gap across an anti-friction coating, timing gears hold the two rotor pairs in phase, and the lubricated components \u2014 bearings and shaft seals \u2014 sit on the oil side of the chamber boundary, with the seals holding the line between the two sides.<\/p>\n

What the large format adds is duty. A stage of this class compresses a production-scale volume of air, hour after hour, and the heat that work generates is carried away by the machine’s cooling circuit while the element itself holds its clearances. The components that age are the ones around the rotors \u2014 the bearing sets that carry the rotor loads and the seals that keep the oil on its own side \u2014 and they are renewed with the element as a whole. That is why the renewal of the 1616716187 is an exchange of complete assemblies rather than a rebuild on site: the factory-set clearances, coatings and seal positions all arrive restored together, and a renewed 1616716187 delivers a chamber that is factory-fresh in every dimension that matters.<\/p>\n

For the air quality argument, the scale changes nothing. The chamber is dry in a large element exactly as it is in a small one, and the certified oil-free classification downstream is held by that dry chamber, not by the machine’s size. When the 1616716187 is renewed, the classification the process was designed around is restored with it.<\/p>\n

Wear Signals in a Large Installation<\/h2>\n

A large element gives the planner more data, and the data moves before anything breaks. Free air delivery slips against the same power input. Specific energy climbs, so the plant pays more kilowatt-hours for each cubic meter of air it produces. Discharge temperature drifts upward as internal clearances begin to leak, and vibration at the air end sharpens as bearing clearances grow. In a plant-room installation these readings come off logged instruments, and the log is what separates an element trend from a system fault: coolers, separators and instrumentation are ruled out first, and the 1616716187 is charged with the fault only when the readings point its way.<\/p>\n

The trend line settles it. A slow climb across quarters of logs tells one story; a step change after a cooling fault tells another, and the history in the log distinguishes the two. When the trend points at the stage, planning starts: the 1616716187 goes on order, and the service window, the lifting arrangement and the technician time are set around the delivery already confirmed. Running a worn element of this class to the end of its life is not a tolerable risk \u2014 internal contact in a dry chamber finishes the rotor profiles for good, and the element comes out as scrap. Renewing on condition, with the 1616716187 scheduled into a booked window, keeps the timing in the hands of the maintenance calendar and restores rated delivery in one planned operation.<\/p>\n

Handling a 548 kg Element<\/h2>\n

The physical work of renewing the 1616716187 is a lifting job, and it rewards a plan written in advance. Five hundred and forty-eight kilograms moves with proper equipment: a forklift or pallet truck to the machine-room door, and a crane or hoist with the capacity and the clear headroom to set the 1616716187 at its mounting position. The route from delivery point to machine \u2014 door widths, floor loading, the space around the compressor \u2014 is walked before the window opens, and the old element’s way out is agreed at the same time, because the new unit does not come off the crane until the old one is clear.<\/p>\n

The fitting sequence itself is mechanical and familiar to any service team: crate opened at the machine, port caps removed only at connection so nothing enters the chamber, mounting faces cleaned, fastener torques set to the values in the compressor manual. The serial numbers of the old and new units, with the 1616716187 reference recorded alongside each, go into the maintenance record before the machine is closed up. Planned this way, the exchange fits inside a scheduled service stop of a fixed and known length \u2014 the element arrives as one complete factory-set assembly, so the time in the window is spent on connections and checks rather than on assembly work.<\/p>\n

That is the practical difference the large format makes: not a harder job, but a scheduled one. A 39 kg element can be swapped on short notice; a 548 kg element is planned like plant work, and the reward for the planning is that the window holds, the crane time is used once, and the compressor returns to rated delivery on the day the calendar said it would.<\/p>\n

Ordering the Correct Element<\/h2>\n

Two details close the identification: the part number and the machine. The 1616716187 is read from the plate on the element being replaced, from the machine parts list or from a previous quotation, and the compressor is identified by the model and serial number on its nameplate. Send the pair together and the 1616716187 match is confirmed in one pass, without a chain of follow-up questions \u2014 which is exactly what a renewal with a booked window needs.<\/p>\n

Where the plate on the old element has worn past reading, the nameplate details still identify the machine, and the parts documentation for that serial carries the element reference. Either route ends in the same place: the correct 1616716187 on order, the identification settled, and the lifting plan and service window aligned with the confirmed supply. One message with the plate photograph and the nameplate details is enough to start all of it.<\/p>\n

What does OFS O-27 stand for?<\/h3>\n

OFS is the Atlas Copco family mark for Oil-Free Screw elements, and O-27 identifies the size class within that family \u2014 the large end of the range, consistent with the element’s 99 x 80 x 68 cm dimensions and 548 kg weight. The complete ordering reference is 1616716187, and that number identifies the part in quotations, order confirmations and the parts documentation.<\/p>\n

What handling does a 548 kg element need?<\/h3>\n

A forklift or pallet truck to the machine-room door and a crane or hoist rated for the weight to set the element at its mounting position, with the route walked in advance. The 1616716187 arrives as one complete assembly, so once it is set, the remaining work is connections, torques and checks inside the booked window.<\/p>\n

How do I confirm the 1616716187 matches my machine?<\/h3>\n

Read the number from the plate on the element being replaced, or take the model and serial number from the compressor nameplate. Send either or both, and the 1616716187 is checked against the parts documentation before the order is placed. One message with those details closes the identification.<\/p>\n

Does the large size change the oil-free property?<\/h3>\n

No. The compression chamber is dry in a large element exactly as in a small one: no oil is injected at any point in the cycle, the working profiles carry a coating and run in a non-contact gap, and the seals keep the lubricated components on the oil side of the boundary. The certified oil-free classification downstream is held by that chamber, not by machine size.<\/p>\n

What happens if a worn element stays in service?<\/h3>\n

Delivery and efficiency fall first, and the plant pays more energy for the same air. In a dry chamber, internal contact finishes the rotor profiles for good, and an element at that stage comes out as scrap. Renewing the 1616716187 on condition, inside a planned window, avoids the unscheduled stop and restores rated output in one operation.<\/p>\n

Is the element supplied as a complete assembly?<\/h3>\n

Yes. The 1616716187 arrives as one factory-set unit with the coated rotor pair, timing gears, bearings and shaft seals in place, so the renewal is an assembly exchange with no on-site internals work. The unit is serialized, and the plate number links it to its documentation through installation and service.<\/p>\n
