Atlas Copco 2236050100 ATSL-165E Oil-Free Scroll Air End

Description

The Atlas Copco 2236050100 is the ATSL-165E air end for the Atlas Copco oil-free scroll compressor range, rated at 3.7 kW and 8 bar. It belongs to a different branch of the Atlas Copco element program than the screw elements most catalogs lead with: the scroll line, where compression is produced by two spiral scrolls in orbital motion rather than meshed rotors. The unit measures 36 x 33 x 30 cm and weighs 19.5 kg, a package that keeps renewal work on the light end of the scale.

This page records the identification and ratings of the 2236050100, explains how scroll compression produces oil-free air, and works through the service structure Atlas Copco has built around it — the kit routing by configuration, the SF series applications, and the ordering details that close the match in one pass.

The ratings are part of the selection. ATSL-165E is the model identity, and the 3.7 kW and 8 bar ratings sit beside it in the Atlas Copco description because the scroll line is offered in more than one pressure class. The rating pair on the machine’s nameplate is the check that closes the match, and with the nameplate details sent together with the part number, the identification of the 2236050100 is complete in one pass.

An Air End from the Oil-Free Scroll Line

Three layers make up the identity, and each does its own job. ATSL-165E is the air end model within the scroll line. The 3.7 kW / 8 bar pair places it in its performance class. And the ordering number is what selects the unit in the parts system: quotations, order confirmations and supply documentation for the 2236050100 all key on that number. The Atlas Copco description reads AIR END ATSL-165E 3.7KW 8BAR, and every element of that line is confirmed the moment the order is placed against the compressor’s own records.

Where the number is read from matters less than that it is read correctly. A photograph of the compressor’s parts list page, the service record from the last renewal, or a previous quotation will each carry the 2236050100 in full. Any of them is enough: the parts system selects the air end by the complete number, and partial references are what create wrong-part orders in the scroll range, where the rating pair separates models that look identical from the outside.

How Scroll Compression Works

A scroll air end compresses with geometry instead of contact. Two spiral scrolls are mated inside the housing: one stays fixed while the other orbits around it without spinning on its own axis. Air drawn in at the outer edge is trapped in crescent-shaped chambers, and as the orbit continues, those chambers spiral inward and shrink, raising the pressure step by step until the air discharges at the center. The 2236050100 carries that principle into the SF range at its 3.7 kW and 8 bar rating.

The orbital motion brings two properties the scroll range is built on. The moving parts are few, so the element runs smoothly and quietly for its size, and the compression chambers form a closed path that needs no injected oil — unlike an oil-injected screw stage, which relies on oil to seal the rotor clearances. Air leaves the 2236050100 dry, which is the property the machines around it were purchased to deliver.

That is the practical meaning of the oil-free scroll classification this air end carries. The scroll principle and the oil-free air path are the same fact read from two sides, and both are why the 2236050100 sits inside machines specified for air that cannot carry oil.

Few moving parts narrow the maintenance conversation as well. With no oil circuit to service around the compression chambers and no rotor clearances to adjust, the condition of the 2236050100 is read almost entirely from the machine’s operating data rather than from physical inspection of the element itself. That makes the logs — delivery, power, discharge conditions — the working document of scroll maintenance, and it makes the renewal of the complete air end the service action that resets everything the logs are measuring.

Service Kits Routed by Compressor Configuration

Atlas Copco’s service documentation for this air end routes the matching kit by compressor configuration rather than by a single kit for every machine. The material accompanying the 2236050100 makes the routing explicit, and the three pairings are worth recording where the maintenance team can see them:

• SF Mono — kit 2902022201
• HDM — kit 2902022203
• SF Multi — kit 2902022207

The configuration names describe how the compressors are set up, not three machine models, and the kit that applies to a specific compressor is confirmed against the latest Atlas Copco service documentation — the ECB API0532 the same material references. Quoting the configuration together with the compressor model and serial number settles the kit question in the first exchange, before the 2236050100 is even on order.

Alongside the complete kits, the ATSL-165E is supported at the repair-parts level, with dedicated sets for the internal components of the air end. For a renewal of the complete unit, the 2236050100 itself is the reference that goes on the order, and the internal sets belong to a different decision — one the service documentation also covers.

The practical habit that keeps the routing reliable is recording the configuration in the compressor’s maintenance file, next to the serial number and the parts fitted. When the next kit or the next 2236050100 is needed, the file answers the configuration question on the spot, and the enquiry that reaches the parts desk carries everything needed for a same-day confirmation — model, serial, configuration and the complete part number.

Applications Across the SF Series

The 2236050100 serves Atlas Copco’s oil-free scroll range. Documented applications place it across the SF4, SF8, SF11, SF15 and SF18 compressors, with service application inside SF Multi configurations as well — one air end model behind a family of machines built around oil-free scroll air. The compressor’s own model and serial number remain the final word on fitment, which is why the nameplate details belong in every enquiry for the 2236050100.

The scroll range exists for points of use where oil-free air is not negotiable and a large installation would be out of proportion: laboratories, medical and dental air, food and beverage lines, electronics benches. Machines of this class run continuously and quietly at the point of use, and the air end inside them is the component whose condition decides whether the air stays at class. Renewing the 2236050100 when wear shows restores that boundary with the same part the machine was built around.

Handling and Renewal

At 19.5 kg the 2236050100 stays on the light side of renewal work — a two-person lift or a small hoist, with no crane and no special route to plan. The unit arrives as a complete air end: the scrolls, their housing and the drive are exchanged as one assembly, so the renewal is a replacement rather than an on-site rebuild.

Wear in a scroll element shows through the operating data, the same way wear announces itself in any compression stage. Delivery that slips against the same power input, discharge conditions that drift, noise that changes character — the compressor’s logs carry the evidence long before the process feels it. When the trend points at the air end, the 2236050100 goes on order while the service window is set, and the machine returns to rated output inside a planned stop measured in hours.

The fitting itself is deliberately uneventful. Port caps stay on until the 2236050100 stands at its mounting position, mounting faces are cleaned before the unit is set, and fastener torques follow the values in the compressor manual. With no oil circuit to reconnect around the compression chambers and no clearances to set, the time in the window goes into connections and checks — and the machine closes up with the new air end already turning.

Ordering the Correct Air End

Two details close the order: the part number and the machine. The 2236050100 is read from the compressor’s parts list, the service documentation or a previous quotation, and the machine is identified by the model and serial number on its nameplate. Send the pair together and the match — the ATSL-165E air end at 3.7 kW and 8 bar — is confirmed in one pass.

The rating check is worth the extra line in the enquiry. The scroll line is offered in more than one pressure class, and the 8 bar rating of the 2236050100 is part of its identity, not a footnote. A quotation prepared against the nameplate details arrives correct the first time, with the configuration noted so the matching service kit travels with the order from the start.

The same record does double duty across the air end’s life. The serial and order details of the 2236050100 as installed, kept in the maintenance file beside the configuration, give the next renewal planner a complete starting point: what is fitted, when it went in, and which kit the service documentation routes to that configuration. Renewal by renewal, the file turns into the compressor’s parts history — and every future enquiry starts from evidence instead of memory.
